Recommendations
| Recommendation | Strength rating |
|---|---|
| Diagnostic evaluation | |
| Check for concomitant diseases, drugs and substances that can interfere with testosterone production/action. | Strong |
| Measure total testosterone in the morning (07.00 and 11.00 hours) and in the fasting state, with a reliable laboratory assay. | Strong |
| Repeat total testosterone on at least two separate occasions when < 12 nmol/L and before starting testosterone therapy. | Strong |
| Use 12 nmol/L total testosterone (3.5 ng/ mL) as a reliable threshold to diagnose late onset hypogonadism (LOH). | Strong |
| Measure sex hormone-binding globulin and free-testosterone calculation when indicated. | Strong |
| Analyse luteinising hormone and follicle- stimulating hormone serum levels to differentiate between the different types of hypogonadism. | Strong |
| Measure prolactin (PRL) levels if low sexual desire (or other suggestive signs/ symptoms) and secondary hypogonadism is present. | Strong |
| Perform pituitary magnetic resonance imaging (MRI) in secondary hypogonadism, with elevated PRL or symptoms specific of a pituitary mass and/or presence of other anterior pituitary hormone deficiency. | Strong |
| Perform pituitary MRI in secondary severe hypogonadism (total testosterone < 6 nmol/L). | Weak |
| Screening | |
| Screen for LOH only in symptomatic men. | Strong |
| Do not use structured interviews and self- reported questionnaires for systematic screening for LOH as they have a low specificity. | Strong |
Recommendations for testosterone therapy outcome
| Recommendation | Strength rating |
|---|---|
| Do not use testosterone therapy in eugonadal men. | Strong |
| Use testosterone therapy as first-line treatment in hypogonadal patients with mild erectile dysfunction (ED). | Strong |
| Use a combination of phosphodiesterase type 5 inhibitors and testosterone therapy in more severe forms of ED. | Weak |
| Use conventional medical therapies for severe depressive symptoms and osteoporosis. | Strong |
| Do not use testosterone therapy to reduce weight and enhance cardio-metabolic status. | Weak |
| Do not use testosterone therapy to improve cognition vitality and physical strength in ageing men. | Strong |
Recommendations for late-onset hypogonadism choice of treatment
| Recommendation | Strength rating |
|---|---|
| Treat, when indicated, organic causes of hypogonadism (e.g., pituitary masses, hyperprolactinemia, etc). | Strong |
| Improve lifestyle and reduce weight (e.g., obesity); withdraw, when possible, concomitant drugs that can impair testosterone production; treat co-morbidity before starting testosterone therapy. | Strong |
| Fully inform patients about expected benefits and adverse effects of any treatment option. Select the testosterone preparation in a joint decision process, and fully inform patients of the risks and benefits. | Strong |
| Use testosterone gels rather than long- acting depot administration when starting initial treatment in high-risk men. | Weak |
Recommendations on safety and monitoring in testosterone treatment
| Recommendation | Strength rating |
|---|---|
| Fully counsel symptomatic hypogonadal men who have been surgically treated for localised prostate cancer (PCa) and who are currently without evidence of active disease considering testosterone therapy, emphasising the benefits and lack of sufficient safety data on long-term follow- up. | Weak |
| Restrict treatment to patients with a low risk for recurrent PCa*. Treatment should start after at least one year follow-up with prostate-specific antigen (PSA) level < 0.01 ng/mL. | Weak |
| Advise patients that safety data on the use of testosterone therapy in men treated for breast cancer are unknown. | Strong |
| Assess cardiovascular risk factors before commencing testosterone therapy. | Strong |
| Assess men with known cardiovascular disease (CVD) for cardiovascular symptoms before testosterone therapy and with close clinical assessment and evaluation during treatment. | Strong |
| Treat men with hypogonadism and pre- existing CVD, venous-thromboembolism or chronic cardiac failure, who require testosterone therapy with caution, by careful clinical monitoring and regular measurement of haematocrit (not exceeding 54%) and testosterone levels. | Weak |
| Exclude a family history of venous- thromboembolism before starting testosterone therapy. | Strong |
| Monitor testosterone, haematocrit at three, six and twelve months after testosterone therapy initiation, and thereafter annually. A haematocrit > 54% requires testosterone therapy adjustment or withdrawal and venesection if required. Re-introduce testosterone therapy at a lower dose once the haematocrit has normalised and consider switching to topical testosterone preparations. | Strong |
| Evaluate patients with polycythaemia vera and those with a higher risk of developing elevated haematocrit every three months during the first year of testosterone therapy, and at least every six months thereafter. | Strong |
| Evaluate total PSA in PCa survivors at three, six and twelve months during the first year of testosterone therapy, and annually thereafter. | Strong |
Recommendations for the diagnosis of erectile dysfunction
| Recommendation | Strength rating |
|---|---|
| Take a comprehensive medical and sexual history in every patient presenting with erectile dysfunction (ED). Consider psychosexual development, including life stressors, cultural aspects, and cognitive/ thinking style of the patient regarding their sexual performance. | Strong |
| Use a validated questionnaire related to ED to assess all sexual function domains (e.g., International Index of Erectile Function) and the effect of a specific treatment modality. | Strong |
| Include a focused physical examination in the initial assessment of men with ED to identify underlying medical conditions and comorbid genital disorders that may be associated with ED. | Strong |
| Evaluate laboratory tests, including glucose and lipid profile and total testosterone, to identify and treat any reversible risk factors and lifestyle factors that can be modified. | Strong |
| Include specific diagnostic tests in the initial evaluation of ED in the presence of the conditions presented in Table 1. | Strong |
Recommendations for treatment of erectile dysfunction
| Recommendation | Strength rating |
|---|---|
| Fully inform patients of the mechanism of action and the ways in which phosphodiesterase type 5 inhibitors (PDE5Is) should be taken, as incorrect use/ inadequate information is the main causes of a lack of response to PDE5Is. | Weak |
| Direct the patient to Cognitive Behaviour Therapy as a psychological approach (include the partner), when indicated, combined with medical treatment to maximise treatment outcomes. | Strong |
| Discuss with patients undergoing active treatment for prostate cancer about the risk of sexual changes other than erectile dysfunction (ED), including sexual desire reduction, changes in orgasm, anejaculation, Peyronie’s like disease and penile size changes. | Strong |
| Initiate lifestyle changes and risk factor modification prior to, or at the same time as, initiating ED treatments. | Strong |
| Use PDE5Is as first-line therapy for the treatment of ED. | Strong |
| Use intracavernous injections as an alternative first-line therapy in well- informed patients or as second-line therapy. | Strong |
| Use topical/intra-urethral alprostadil as an alternative first-line therapy in well- informed patients who: • do not wish to have or are not suitable for oral vasoactive therapy; • do not wish to have intracavernous injections; • in patients who prefer a less-invasive therapy. | Weak |
| Use low intensity shockwave treatment (LI-SWT) with/without PDE5Is in patients: • with mild vasculogenic ED; • as an alternative therapy in well- informed patients who do not wish to have or are not suitable for oral vasoactive therapy; • who are vasculogenic ED patients that are poor responders to PDE5Is. | Weak |
| Use vacuum erection devices in well- informed patients requesting non-invasive, drug-free management of ED. | Weak |
| Use supplements with L-arginine or ginseng daily in men with mild ED who refuse pharmacological treatment after counselling them that the improvement of EF could be mild. | Weak |
| Implant a penile prosthesis if other treatments fail or depending upon patient preference. Patients should be fully informed of the benefits an harms associated with the procedure. | Strong |
| Inform patients that available data are inadequate to support any specific regimen for penile rehabilitation. | Weak |
| Start pro-erectile treatments at the earliest opportunity after radical prostatectomy/ pelvic surgery and other curative treatments for prostate cancer. | Weak |
Recommendations for the diagnostic evaluation of premature ejaculation
| Recommendation | Strength rating |
|---|---|
| Perform the diagnosis and classification of premature ejaculation (PE) based on medical and sexual history, which should include assessment of intravaginal ejaculatory latency time (IELT) (self- estimated), perceived control, distress and interpersonal difficulty due to the ejaculatory dysfunction. | Strong |
| Use patient-reported outcomes in daily clinical practice. | Weak |
| Include physical examination in the initial assessment of PE to identify anatomical abnormalities that may be associated with PE or other sexual dysfunctions, particularly erectile dysfunction. | Strong |
| Do not perform routine laboratory or neuro- physiological tests. They should only be directed by specific findings from history or physical examination. | Strong |
Recommendations for the treatment of premature ejaculation
| Recommendation | Strength rating |
|---|---|
| Treat erectile dysfunction (ED), other sexual dysfunction or genitourinary infection (e.g., prostatitis) first. | Strong |
| Use either dapoxetine or the lidocaine/ prilocaine spray as first-line treatments for lifelong premature ejaculation (PE). | Strong |
| Use off-label oral treatment with daily selective serotonin re-uptake inhibitor (SSRIs) or daily/on-demand clomipramine as a viable alternative for second-line treatments. | Strong |
| Use off-label tramadol with caution as a viable on-demand third-line treatment alternative to on-demand/daily antidepressants (SSRIs or clomipramine) | Strong |
| Use PDE5Is alone or in combination with other therapies in patients with PE (without ED). | Strong |
| Use psychological/behavioural therapies in combination with pharmacological treatment in the management of acquired PE. | Weak |
| Use hyaluronic acid injection with caution as a treatment option for PE compared to other more established treatment modalities. | Weak |
| Do not perform dorsal neurectomy as more safety data are warranted. | Weak |

| Recommendation | Strength rating |
|---|---|
| Perform the diagnosis and classification of low sexual desire (LSD) based on medical and sexual history, which could include validated questionnaires. | Weak |
| Include physical examination in the initial assessment of LSD to identify anatomical abnormalities that may be associated with LSD or other sexual dysfunctions, particularly erectile dysfunction. | Weak |
| Perform laboratory tests to rule out endocrine disorders. | Strong |
| Modulate chronic therapies which can negatively impact toward sexual desire. | Weak |
| Provide testosterone therapy if LSD is associated with signs and symptoms of testosterone deficiency. | Strong |
Recommendation
| Recommendation | Strength rating |

Recommendations for diagnosis of Peyronie’s disease
| Recommendation | Strength rating |
|---|---|
| Take a medical and sexual history of patients with Peyronie’s disease (PD), include duration of the disease, pain on erection, penile deformity, difficulty in vaginal/anal intromission due to disabling deformity and erectile dysfunction (ED). | Strong |
| Perform a physical examination, including assessment of palpable plaques, stretched or erect penile length, degree of curvature (self-photography, vacuum-assisted erection test or pharmacological-induced erection) and any other related diseases (e.g., Dupuytren’s contracture, Ledderhose disease) in patients with PD. | Strong |
| Use the intracavernous injection (IC) method in the diagnostic work-up of PD to provide an objective assessment of penile curvature with an erection. | Weak |
| Use the PD specific questionnaire especially in clinical trials, but mainstream usage in daily clinical practice is not mandatory. | Weak |
| Do not use ultrasound (US), computed tomography or magnetic resonance imaging to assess plaque size and deformity in routine clinical practice. | Weak |
| Use penile Doppler US in the case of diagnostic evaluation of ED, to evaluate penile haemodynamic and vascular anatomy, and to assess location and calcification of plaques, especially prior to surgery. | Weak |
Recommendations for non-operative treatment of Peyronie’s disease
| Recommendation | Strength rating |
|---|---|
| Offer conservative treatment to patients not fit for surgery or when surgery is not acceptable to the patient. | Strong |
| Fully counsel patients regarding all available treatment options and outcomes before starting any treatment. | Strong |
| Do not offer oral treatment with vitamin E, potassium para-aminobenzoate (potaba), tamoxifen, pentoxifylline, colchicine and acetyl esters of carnitine to treat Peyronie’s disease (PD). | Strong |
| Use nonsteroidal anti-inflammatory drugs to treat penile pain in the acute phase of PD. | Strong |
| Use extracorporeal shockwave treatment (ESWT) to treat penile pain in the acute phase of PD. | Weak |
| Use phosphodiesterase type 5 inhibitors to treat concomitant erectile dysfunction or if the deformity results in difficulty in penetrative intercourse in order to optimise penetration. | Weak |
| Offer intralesional therapy with interferon alpha-2b to patients with stable curvature dorsal or lateral > 30o seeking a minimal invasive procedure. | Weak |
| Offer intralesional therapy with Collagenase Clostridium Histolyticum to patients with stable PD and dorsal or lateral curvature > 30o, who request non- surgical treatment, although the placebo effects are high. | Strong |
| Do not offer intralesional treatment with steroids to reduce penile curvature, plaque size or pain. | Strong |
| Do not use intralesional platelet-rich plasma or hyaluronic acid, either alone or in combination with oral treatment, to reduce penile curvature, plaque size or pain outside the confines of a clinical trial. | Strong |
| Do not offer ESWT to improve penile curvature and reduce plaque size. | Strong |
| Offer penile traction devices and vacuum devices to reduce penile deformity or as part of a multimodal therapy approach, although outcome data is limited. | Weak |
Recommendations for the surgical treatment of Peyronie's disease
| Recommendation | Strength rating |
|---|---|
| Perform surgery only when Peyronie’s disease (PD) has been stable for at least three months (without pain or deformity deterioration), which is usually the case after twelve months from the onset of symptoms, and intercourse is compromised due to the deformity. | Strong |
| Assess penile length, curvature severity, erectile function (including response to pharmacotherapy in case of erectile dysfunction [ED]) and patient expectations prior to surgery. | Strong |
| Use tunical shortening procedures as the first treatment option for congenital penile curvature and for PD with adequate penile length and rigidity, less severe curvatures and absence of complex deformities (hourglass or hinge). The type of procedure used is dependent on surgeon and patient preference, as no procedure has proven superior to its counterparts. | Weak |
| Use tunical lengthening procedures for patients with PD and normal erectile function, without adequate penile length, severe curvature or presence of complex deformities (hourglass or hinge). The type of graft used is dependent on the surgeon and patient factors, as no graft has proven superior to its counterparts. | Weak |
| Do not use the sliding techniques as there is a significant risk of life changing complications (e.g., glans necrosis). | Strong |
| Do not use synthetic grafts in PD reconstructive surgery. | Strong |
| Use penile prosthesis implantation, with or without any additional straightening procedures (modelling, plication, incision or excision with or without grafting), in PD patients with ED not responding to pharmacotherapy. | Strong |
Recommendations for classification of short penile size
| Recommendation | Strength rating |
|---|---|
| Perform a detailed genital examination in all men and particularly in men with BMI > 30, lichen sclerosis or penile cancer history and complaints of urinary/sexual difficulties or poor cosmesis to exclude the presence of an adult acquired buried penis (AABP) condition. | Strong |
| Use classification systems to classify AABP clinical presentation and surgical management. | Weak |
| Inquire on the presence of body dysmorphic disorder/penile dysmorphic disorder in patients with normal-sized penis complaining of short penile size. | Strong |
Recommendations for diagnosis of short penile size
| Recommendation | Strength rating |
|---|---|
| Take a comprehensive medical and sexual history in every patient presenting complaining of short penile size. | Strong |
| Use stretched penile length measurements (skin junction-to-glans tip or dorsally from the pubic bone-to-glans tip) to define penile length. | Weak |
| Measure flaccid and erect measurements to assess penile length in detail. | Weak |
| Measure penile girth in every patient presenting complaining of a short penile size. | Weak |
| Use validated questionnaires to screen for body dysmorphic disorder (BDD) in cases of a normal-sized penis. | Weak |
| Use validated questionnaires (e.g., IIEF-15, BAPS) to assess baseline sexual function and beliefs concerning penile size. | Weak |
| Refer patients with BDD for mental health counselling. | Strong |
Recommendations for non-surgical management of short penile size
| Recommendation | Strength rating |
|---|---|
| Consider psychotherapy when psychopathological comorbidities are detected, or when aversive relationship dynamics may underlie the request for penile augmentation. | Strong |
| Consider the use of penile traction therapy as a conservative treatment to increase penile length. | Weak |
| Consider the use vacuum erection devises to increase penile length. | Weak |
| Use endocrinological therapies to restore penile size in boys with micropenis or disorders of sex development. | Strong |

Recommendations surgical treatment
| Recommendation | Strength rating |
|---|---|
| Adult acquired buried penis (AABP) | |
| Extensively counsel patients on the benefits and complications of AABP surgery. | Strong |
| Initiate lifestyle changes and modification of risk factors, particularly weight loss, to minimise AABP surgical complications and to optimise surgical outcomes. | Strong |
| Consider surgical treatment to address AABP. | Weak |
| Congenital intrinsic penile shortness | |
| Perform surgery for AABP in high volume centres. | Strong |
| Use suspensory ligament release (SLR), ventral phalloplasty and suprapubic lipoplasty/liposuction/lipectomy to address penile lengthening. | Weak |
| Extensively discuss possible complications related to SLR, ventral phalloplasty and suprapubic lipoplasty/liposuction/ lipectomy. | Strong |
| Use total phallic reconstruction to restore genital anatomy in patients affected by congenital micropenis. | Weak |
| Acquired penile shortness | |
| Do not recommend penile prosthesis implantation, penile disassembly or sliding technique to patients seeking penile lengthening options. | Strong |
| Use total phallic reconstruction to restore genital anatomy in genetic males with penile inadequacy due to traumatic loss. | Weak |
Recommendations
| Recommendation | Strength rating |
|---|---|
| Counsel patients extensively regarding the risks and benefits of penile girth enhancement techniques. | Strong |
| Do not use silicone, paraffin and petroleum jelly (Vaseline) to address penile girth enhancement. | Strong |
| Use hyaluronic acid, soft tissue fillers and autologous fat injection to address penile girth enhancement. | Weak |

Recommendations for the diagnosis of ischaemic priapism
| Recommendation | Strength rating |
|---|---|
| Take a comprehensive history to establish the diagnosis which can help to determine the priapism subtype. | Strong |
| Include a physical examination of the genitalia, perineum and abdomen in the diagnostic evaluation. | Strong |
| Include a full blood count, white blood cell count with blood cell differential, platelet count and coagulation profile for laboratory testing. Perform directed further laboratory testing depending upon history and clinical and laboratory findings. Perform a complete evaluation of all possible causes of priapism in children. | Strong |
| Perform a haemoglobinopathy screen in patients with low flow priapism who are at high risk of sickle cell disease or thalassemia. | Strong |
| Analyse the blood gas parameters from blood aspirated from the penis to differentiate between ischaemic and non- ischaemic priapism. | Strong |
| Perform colour duplex ultrasound of the penis and perineum before aspiration to differentiate between ischaemic and non- ischaemic priapism. | Strong |
| Use magnetic resonance imaging of the penis in cases of prolonged ischaemic priapism or refractory priapism, and as an adjunct to predict smooth muscle viability. | Weak |
Recommendations for the treatment of ischaemic priapism
| Recommendation | Strength rating |
|---|---|
| Start management of ischaemic priapism as early as possible (within four to six hours) and follow a stepwise approach. | Strong |
| Decompress the corpus cavernosum by penile aspiration and washout until fresh red blood is obtained as first treatment step. | Strong |
| Replace blood aspiration with intracavernous injection of a sympathomimetic drug as the first step in priapism secondary to intracavernous injections of vasoactive agents. | Strong |
| Perform intracavernous injection of a sympathomimetic drug in priapism that persists despite aspiration. | Strong |
| Repeat aspiration and intracavernous injection of a sympathomimetic drug in cases that persist despite prior aspiration and intracavernous injection of a sympathomimetic drug, before considering surgical intervention. | Strong |
| Treat ischaemic priapism associated with sickle cell disease in the same fashion as idiopathic ischaemic priapism. Do not use exchange transfusion as a primary treatment. Provide other supportive measures (intravenous hydration, oxygen administration with alkalisation with bicarbonate, blood exchange transfusions), but do not delay initial treatment to the penis. | Strong |
| Proceed to surgical treatment only when blood aspiration and intracavernous injection of sympathomimetic drugs have failed. | Strong |
| Perform distal shunt surgical procedures first and combine them with tunnelling if necessary. | Weak |
| Use proximal procedures in cases of distal shunt failure (< 48 hours) or in patients who do not wish to proceed with immediate penile implant insertion. | Weak |
| Discuss implantation of a penile prosthesis in cases of delayed presentation (> 48 hours) and in cases refractory to injection therapy and distal shunting. | Weak |
| Delay implantation of a penile prosthesis if a shunt has been performed, to minimise the risk of infection and erosion of the implant. | Strong |
| Decide on which type of implant to insert based on: • patient suitability; • surgeons’ experience; and • availability and cost of equipment. If a malleable penile prosthesis is implanted it can be exchanged later for an inflatable penile implant. | Strong |
Recommendations for treatment of stuttering priapism
| Recommendation | Strength rating |
|---|---|
| Manage each acute episode according to the treatment recommendation for ischaemic priapism. | Strong |
| Use hormonal therapies (mainly gonadotropin-receptor hormone agonists or antagonists) and/or anti-androgens for the prevention of future episodes in patients with frequent relapses. Do not use them before sexual maturation is reached. | Weak |
| Initiate treatment with phosphodiesterase type 5 inhibitors only when the penis is in its flaccid state. | Weak |
| Use digoxin, α-adrenergic agonists, baclofen, gabapentin or terbutaline only in patients with frequent and uncontrolled relapses. | Weak |
| Use intracavernous self-injections of sympathomimetic drugs at home for treatment of acute episodes on an interim basis until ischaemic priapism has been alleviated. | Weak |
Recommendations for the diagnosis of non-ischaemic priapism
| Recommendation | Strength rating |
|---|---|
| Take a comprehensive history to establish the diagnosis, which can help to determine the priapism subtype. | Strong |
| Include a physical examination of the genitalia, perineum and abdomen in the diagnostic evaluation. | Strong |
| Include a neurological examination if neurogenic non-ischaemic priapism is suspected. | Strong |
| Include complete blood count, with white blood cell differential, and coagulation profile for laboratory testing. | Strong |

| Perform colour duplex ultrasound of the penis and perineum to differentiate between ischaemic and non-ischaemic priapism. | Strong |
| Perform selected pudendal arteriography when embolisation is planned for non- ischaemic priapism. | Strong |
Recommendations for the treatment of non-ischemic priapism
| Recommendation | Strength rating |
|---|---|
| Perform definitive management for non- ischaemic priapism at the discretion of the treating physician as it is not a medical emergency. | Weak |
| Manage non-ischaemic priapism conservatively with the use of site-specific perineal compression as the first step. Consider androgen deprivation therapy only in adults. | Weak |
| Perform selective arterial embolisation when conservative management has failed. | Strong |
| Perform the first selective arterial embolisation using temporary material. | Weak |
| Repeat selective arterial embolisation with temporary or permanent material for recurrent non-ischaemic priapism following selective arterial embolisation. | Weak |
| Reserve selective surgical ligation of a fistula as a final treatment option when repeated arterial embolisations have failed. | Weak |
Recommendations
| Recommendation | Strength rating |
|---|---|
| Include a parallel assessment of the fertility status, including ovarian reserve, of the female partner during the diagnosis and management of the infertile male, since this might determine decision making in terms of timing and therapeutic strategies (e.g., assisted reproductive technology (ART) versus surgical intervention). | Strong |
| Examine all men seeking medical help for fertility problems, including men with abnormal semen parameters. | Strong |
| Take a complete medical reproductive and family history, assessment of lifestyle and behaviour risk factors, physical examination and semen analysis. | Strong |

| Provide genetic counselling in all couples with a genetic abnormality found on clinical or genetic investigation and in patients who carry a (potential) inheritable disease. | Strong |
| Perform scrotal US in patients with infertility, as there is a higher risk of testis cancer. | Weak |
| Discuss invasive diagnostic modalities (e.g., US-guided testicular biopsy with frozen section versus radical orchidectomy versus surveillance) in infertile men with US-detected indeterminate testicular lesions, especially if additional risk factors for malignancy are present in a multidisciplinary team setting. | Weak |
| Perform transrectal US if a partial or complete distal obstruction is suspected. | Strong |
Recommendations
| Recommendation | Strength rating |
|---|---|

Recommendations
| Recommendation | Strength rating |
|---|---|
| Advise men with testicular microcalcification (TM) to perform self-examination even without additional risk factors, as this may result in early detection of a testicular germ cell tumour (TGCT). | Weak |
| Do not perform testicular biopsy, follow- up scrotal ultrasound (US), measure biochemical tumour markers, or abdominal or pelvic computed tomography, in men with isolated TM without associated risk factors (e.g., infertility, cryptorchidism, testicular cancer, and atrophic testis). | Strong |
| Offer testicular biopsy to infertile men with TM, who belong to one of the following higher risk groups: spermatogenic failure (infertility), bilateral TM, atrophic testes (< 12 mL), history of undescended testes and TGCT. | Weak |
| Perform inguinal surgical exploration with testicular biopsy or offer orchidectomy after multi-disciplinary team meeting and discussion with the patient, if there are suspicious findings on physical examination or US in patients with TM with associated lesions. | Strong |
| Manage men treated for TGCT in a multi- disciplinary team setting with a dedicated late-effects clinic and survivorship program, since they are at increased risk of developing hypogonadism, sexual dysfunction and cardiovascular risk. | Strong |
| Perform sperm cryopreservation prior to planned orchidectomy or before additional neoadjuvant or adjuvant oncological therapies. | Strong |
| Offer onco-testicular sperm extraction (onco-TESE) at the time of radical orchidectomy in men with testicular cancer and azoospermia or severe abnormalities in their semen parameters. | Strong |
Recommendations
| Recommendation | Strength rating |
|---|---|
| In adolescents offer surgery for varicocele associated with a persistent small testis (size difference of > 2 mL or 20%), which should be confirmed on two subsequent visits performed six months apart. | Strong |
| Do not treat varicocele in infertile men who have normal semen analysis and in men with a sub-clinical varicocele. | Strong |
| Treat infertile men with a clinical varicocele, abnormal semen parameters and otherwise unexplained infertility in a couple where the female partner has good ovarian reserve to improve fertility rates. | Strong |
| Varicocelectomy may be considered in men with raised sperm DNA fragmentation with otherwise unexplained infertility or who have suffered from failure of assisted reproductive techniques, including recurrent pregnancy loss, failure of embryogenesis and implantation. | Weak |
Recommendations
| Recommendation | Strength rating |
|---|---|
| Treat male accessory gland infections as it may improve sperm quality, although it does not necessarily improve the probability of conception. | Weak |
| Refer sexual partners of patients with accessory sex gland infections that are known or suspected to be caused by sexually transmitted diseases for evaluation and treatment. | Strong |
Recommendations
| Recommendation | Strength rating |
|---|---|
| Inform infertile men about the detrimental effects of obesity, low physical activity, smoking and high alcohol intake on sperm quality and testosterone levels. Therefore, advise infertile men to improve life style factors to improve their chances of conception. | Strong |

| Offer dopamine agonist therapy in men with proven hyperprolactinemia to improve sperm quality. | Weak |
| Withdraw anabolic steroids in infertile men for 6 to 12 months before considering treatment with selective oestrogen receptor modulators or gonadotrophin therapy to induce spermatogenesis. | Weak |
Recommendations
| Recommendation | Strength rating |
|---|---|
| Perform microsurgical vasovasostomy or epididymovasostomy for azoospermia caused by vasal or epididymal obstruction in men with female partners with good ovarian reserve. | Strong |
| Use sperm retrieval techniques, such as microsurgical epididymal sperm aspiration (MESA), testicular sperm extraction (TESE) and percutaneous techniques (PESA and TESA) either as an adjunct to reconstructive surgery, or if the condition is not amenable to surgical repair, or when the ovarian reserve of the partner is limited or patient preference is not to undertake surgical reconstruction and the couple prefer to proceed to ICSI treatment directly. | Strong |
Recommendations
| Recommendation | Strength rating |
|---|---|
| Confirm a diagnosis of non-obstructive azoospermia (NOA) in two consecutive semen analyses, when no sperm are found after centrifugation. | Strong |
| Perform a comprehensive assessment, including detailed medical history, hormonal profile, genetic tests and scrotal ultrasound to investigate the underlying aetiology and associated co-morbidity in patients with NOA. | Strong |
| Genetic counselling is mandatory in couples with genetic abnormalities prior to any assisted reproductive technology. | Strong |
| Perform surgery for sperm retrieval in men who are candidates for assisted reproductive technology (i.e., ICSI). | Strong |
| Do not perform surgery for sperm retrieval in patients with complete AZFa and AZFb microdeletions, since the chance of sperm retrieval is zero. | Strong |
| Do not perform fine needle aspiration (FNA) and testicular sperm aspiration (TESA) in patients with NOA. | Strong |
| Do not perform FNA mapping as a prognostic procedure prior to definitive testicular sperm extraction (any type) in patients with NOA. | Weak |
| Use microdissection TESE as the treatment of choice to retrieve sperm in patients with NOA. | Weak |
| Do not consider pre-operative biochemical and clinical variables as sufficient and reliable predictors of sperm retrieval outcome at surgery in patients with NOA. | Weak |
| Do not routinely use medical therapy, e.g., hormonal stimulation in men with NOA and hypergonadotrophic hypogonadism before c/mTESE to improve sperm recovery. | Weak |

| Indications for specific diagnostic tests for ED |
|---|
| Primary ED (not caused by acquired organic disease or psychogenic disorder). |
| Young patients with a history of pelvic or perineal trauma, who could benefit from potentially curative revascularisation surgery or angioplasty. |
| Patients with penile deformities that might require surgical correction (e.g., Peyronie’s disease and congenital penile curvature). |
| Patients with complex psychiatric or psychosexual disorders. |
| Patients with complex endocrine disorders. |
| Specific tests may be indicated at the request of the patient or their partner. |
| Medico-legal reasons (e.g., implantation of penile prosthesis to document end-stage ED, and sexual abuse). |
| Specific diagnostic tests for ED |
| Nocturnal Penile Tumescence and Rigidity (NTPR) using Rigiscan®. |
| Vascular studies: • Intracavernous vasoactive drug injection. • Penile dynamic duplex ultrasonography. • Penile dynamic infusion cavernosometry and cavernosography. • Internal pudendal arteriography. |
| Specialised endocrinological studies. |
| Specialised psycho-diagnostic evaluation. |
