BACKGROUND: Following on from the Rapport vers une stratégie nationale de lutte contre l\'infertilité (Report on a national strategy to combat infertility) submitted to the French Minister of Health in 2022, whose objective 13 is: to better identify and diagnose male infertility, we wanted to clarify with reproductive specialists what role the urologist should play in the management of the infertile couple.
METHODS: An expert consensus was reached with the Pedagogical Committee and pilots of the Transversal Specialized Training in Reproductive Medicine and Biology - Andrology, and with the presidents, board and scientific council of the French Federation for Reproductive Study (FFER).
RESULTS: In the case of infertility in a couple, the fertility of both partners should be assessed from the outset, and in the event of abnormality or failure of ART, the patient should be referred to a uro-andrologist for expert management. The uro-andrologist will set up medical or surgical treatments to improve the prognosis of the man\'s fertility, in conjunction with the entire ART team. It is also important for the urologist/andrologist to take charge of the man\'s health before conception, because of the benefits for the patient himself and for his offspring.
CONCLUSIONS: This expert consensus has shed light on the role of the uro-andrologist in the ART pathway, on the need for training in Andrology and on the medical demography required.

BACKGROUND: At a time when increasing attention is being paid to the limitations and risks of in vitro fertilisation techniques, surgeries to improve male fertility are attracting growing interest.
METHODS: Systematic review based on a Pubmed search of surgeries to improve male fertility.
RESULTS: Vasovasostomy (VV) gives patency rates of 70-97% and pregnancy rates of 30-76%. Vasoepididymostomy (VE) gives patency rates of 80-84%, with pregnancy rates of 40-44%. The duration of obstruction and the age of the partner are 2 predictive parameters for the occurrence of a natural pregnancy. In cases of obstructive azoospermia due to pelvic obstruction (prostatic cyst, obstruction of the ejaculatory ducts), several surgical procedures may be proposed. Transurethral resection of the ejaculatory ducts leads to an improvement in sperm parameters in 63-83% of patients, with spontaneous pregnancy occurring in 12-31% of cases. Microsurgical cure of varicocele by the subinguinal route is a benchmark technique with recurrence rates of less than 4%. It improves live birth and pregnancy rates, both naturally and by in vitro fertilization, as well as sperm count, motility and DNA fragmentation rates.
CONCLUSIONS: Whenever possible, the urologist should present the surgical options for improving male fertility to the ART team and to the couple, discussing the benefit/risk balance of the operation as part of a personalized approach.

BACKGROUND: Varicocele is the most common correctable cause of male infertility. It was the subject of recent Association française d\'urologie (AFU) Comité d\'andrologie et de médecine sexuelle (CAMS) recommendations. Since then, the literature has provided additional information. This review will comprehensively reassess current indications for the treatment of varicocele, and revisit contemporary issues in the light of current advances.
METHODS: Update of the literature search carried out as part of the CAMS recommendations for the period between 2020 and 2023.
RESULTS: Microsurgical sub-inguinal varicocelectomy remains the surgical treatment of choice for infertile men with clinical varicocele and abnormal sperm parameters. It offers recurrence rates of less than 4%. It significantly improves both natural and in vitro fertilization live birth and pregnancy rates, as well as sperm count, total and progressive motility, morphology and DNA fragmentation rates. All in all, it modifies the MPA strategy in around one in two cases. Varicocele grade and bilaterality are predictive of improved sperm parameters and pregnancy rate. Treatment of subclinical varicocele is not recommended. Complications are rare, notably hydroceles (0.5%), unilateral testicular atrophy due to arterial damage (1/1000), hematomas, delayed healing and postoperative pain. Retrograde embolization is an alternative to surgery.
CONCLUSIONS: Whenever possible, the urologist should present and discuss treatment options for varicocele with the MPA team and the patient, taking a personalized approach.

BACKGROUND: Among couples consulting for infertility, there is a male component, either alone or associated with a female aetiology in around one in 2 cases.
METHODS: Bibliographic search in PubMed using the keywords \"male infertility\", \"diagnosis\", \"management\" and \"evaluation\" limited to clinical articles in English and French prior to 1/01/2023.
RESULTS: The AFU recommends: (1) a complete medical history including: family history, patient history affecting fertility, lifestyle habits (toxicity), treatments, symptoms, sexual dysfunctions; (2) a physical examination including: BMI, signs of hypogonadism, secondary sexual characteristics, scrotal examination (volume and consistency of testes, vas deferens, epididymal or testicular nodules, presence of varicocele); (3) two spermograms, if abnormal on the first; (4) a systematic scrotal ultrasound,± an endorectal ultrasound depending on the clinic; (5) a hormonal work-up (testosterone, FSH; if testosterone is low: LH assay to differentiate between central or peripheral hypogonadism); (6) karyotype if sperm concentration≤10 million/mL; (7) evaluation of Y chromosome microdeletions if concentration≤1 million/mL; (8) evaluation of the CFTR gene in cases of suspected bilateral or unilateral agenesis of the vas deferens and seminal vesicles. The role and usefulness of direct and indirect tests to assess the effects of oxidative stress on sperm DNA will also be explained.
CONCLUSIONS: This review complements and updates the AFU/SALF 2021 recommendations.

BACKGROUND: The subinguinal microsurgical varicocelectomy is considered as the gold standard surgical technique for the treatment of varicocele. The objective of this study is to evaluate the results of this technique on the resolution of pain and the parameters of sperm analysis.
METHODS: Single-center, retrospective study that includes 22 patients who have been operated over a period of six months for a clinically palpable varicocele via the microsurgical subinguinal technique. Nine patients were operated for pain and 13 patients for infertility with an abnormality of their sperm analysis.
RESULTS: All the patients operated for pain had a complete resolution of pain at the postoperative follow-up (3 months). Concerning the patients operated for infertility, 76.92% of the patients had a normal sperm analysis, 7.69% of the patients presented a partial improvement, and 15.39% of the patients without any improvement. Analysis of sperm\'s parameters at 3 months showed a significant improvement in the morphology (4.3% vs 6.69% of typical forms according to Kruger ; P<0.05) and mobility (progressive mobility 15.6% vs 23% postoperatively; P<0.01). A non-significant improvement (low sample) in the concentration was noted (21.58 million/mL preoperative vs 34.9 million/mL postoperative, P=0.08). Pregnancies are noted in 38.5% of patients. A postoperative complication was noted with surgical site infection resolved with antibiotics.
CONCLUSIONS: This single-center study confirms that the treatment of varicocele by subinguinal microsurgical route is an effective therapeutic strategy on symptomatic varicocele and in infertile men. This technique is associated with few complications.
METHODS:

BACKGROUND: Although the progress in diagnosis methods revealed a high incidence of infra-clinical varicocele, the clinical signification of this pathology is controversial. We compared left unilateral varicocelectomy to bilateral surgery in patients with left clinical varicocele associated to an infra-clinical right one.
METHODS: It is a retrospective study conducted between January 2007 and December 2015 concerning men followed for a varicocele related infertility (one-year or more primary infertility) with two altered sperm analysis (oligospermia and/or asthenospermia) and had a left clinical varicocele associated to right infra-clinical one detected at Doppler Ultrasound. Surgical techniques used were open surgery (sub-inguinal way), antegrade sclerotherapy and coelioscopy. All patients were reviewed with a 6 month post operatively spermogram and minimum follow up of 1 year.
RESULTS: Our study included 95 men. Thirty-five patients have had a unilateral left surgery (Group I) and 60 patients have had a bilateral surgical treatment (Group II). The pre-operative spermatic parameters (concentration and progressive mobility) were comparable for the 2 groups. After the surgical treatment, an improvement of these parameters was noted in all the patients without significant difference between the two groups regarding sperm concentration (24.07±9.36×106/mL Vs 23.29±3.88×106/mL) and their progressive mobility (30.47±9.04% Vs 32.39±9.54%). The spontaneous pregnancy rate was 22.8% for patients in group I and 26.6% for those in group II without any statistically difference (p=0.68).
CONCLUSIONS: Treatment of a right s infra-clinical varicocele, when combined with a left clinical varicocele, gave better results in terms of sperm parameters and spontaneous pregnancy than unilateral varicocelectomy but without statistically significant results.

The diagnosis of varicocele is clinical, carried out in supine and standing position and in Valsalva maneuver. Only clinical varicoceles have to be treated. A scrotal ultrasound with Doppler is generally performed as part of the infertile man\'s evaluation or in case of examination difficulties. The main indication for varicocele treatment is the adult man with clinical varicocele and abnormalities of sperm parameters, in a context of infertility of couple, with a partner having a satisfactory ovarian reserve and no cause of female infertility or a curable infertility cause. The decision to treat varicocele must therefore be taken after evaluation of the two partners of the couple. Adults with symptomatic varicocele and those with spermogram abnormalities may also be offered a cure for their varicocele even in the absence of a paternity plan, as well as adolescents with reduced testicular growth, an ipsilateral decrease testicular volume, or a size gradient between the 2 testes. The cure of varicocele can be carried out by surgery or by percutaneous embolization. Microsurgery (inguinal or subinguinal) offers lower rates of recurrence and complications than high surgical approaches (laparoscopic or not) and surgeries without magnification. It is therefore the reference surgical technique. Percutaneous retrograde embolization is a minimally invasive alternative to microsurgery offering satisfactory outcomes with rare and often benign complications. The cure for varicocele results in an improvement in sperm parameters and recent data seem to confirm that it increases the natural pregnancy rate. These results appear after a delay of 3 to 9 months (at least 1 to 2 cycles of spermatogenesis). When the sperm involvement was severe (azoospermia, severe oligospermia), the improvement of the spermogram allow (1) to avoid surgery testicular sperm extraction or (2) perform intrauterine insemination rather than ICSI.

OBJECTIVE: To evaluate if a potential relationship exists between sperm nuclear DNA damage and clinical varicocele and to determine the impact of clinical varicocele on standard semen parameters.
METHODS: A prospective study involving 30 infertile patients with clinical varicocele and 15 controls patients referred to our laboratory for routine spermiological exploration. Spermograms were performed and analyzed according to World Health Organisation (WHO) guidelines 2010. The DNA fragmentation was detected by the terminal desoxynucleotidyl transferase-mediated deoxyuridine triphosphate biotin nick-end labeling (TUNEL) assay.
RESULTS: The DNA fragmentation index (DFI) was significantly higher in patients with clinical varicocele compared to controls (13.3±3.4% versus 6.1±2.5%, P=0.0001). In addition, the DFI was positively and significantly correlated with the degree of severity of varicocele thus the DFI was 15.24±1.9% in patients with grade 3 versus 12.92±3.5% in those with grade 2(P<0.0001). However, an abnormality of at least one of the spermatic parameters was found in 90% of varicocele patients, and all semen characteristics such as sperm count, vitality, mobility and typical forms were decreased compared to the controls. Furthermore, statistically significant negative correlations were noted between sperm DNA fragmentation index and sperm concentration (P=0.0001), motility (P=0.03), and normal sperm morphology (P=0.03).
CONCLUSIONS: Clinical varicocele generates a significant increase of sperm abnormalities and DNA damage, and these changes are positively correlated with varicocele grade. Sperm DNA damage independent of its cause, may affect the quality of the ejaculated sperm and may have implications on patient\'s fertility potential.

OBJECTIVE: Study the early postoperative course of sperm parameters after antegrade sclerotherapy (AS) of clinical left varicocele (CLV) in men consulting for infertility with sperm disruption, and to validate the efficacy and safety of treatment.
METHODS: Monocentric retrospective observational study of men with CLV, consultant in medically assisted procreation center for primary or secondary infertility of the couple. All patients were operated by SA via scrotal approach. After clinical and ultrasound checks at 6 weeks, a control spermogram was performed at 3-6 months of surgery. The following parameters were analyzed: sperm count, motility, percent of normal form, and total number of motile sperm (\"total motile sperm count\" [TMSC]).
RESULTS: The study involved 138 men (median age 33 years) with sperm alteration. All patients benefited from AS of their CLV. No Clavian complication > 1 was observed. Postoperative control demonstrated a significant improvement in all spermogram parameters, with a median progression of 40% of the count (55 vs 32×106), 80% of the concentration (20.3 vs 11.1×106/ml), 30% of the motility (34.7% vs 26.5%), 60% of the normal form percentage (4.0 vs 2.5%) and the 75% TMSC (41.5 vs 23%), 7×106) (p<0.005).
CONCLUSIONS: SA is an effective and safe technique for treating CLV and improving sperm parameters fertility indicators. Our results suggest that this treatment may be recommended to infertile men with CLV in the management of infertility of the couple.

BACKGROUND: Subinguinal microscopic ligation is the current standard of treatment of varicocele, and percutaneous embolization is a new alternative. We aimed to compare these procedures for reproductive and functional aspects.
METHODS: A consecutive series of 76 patients with clinical varicocele, alteration of semen parameters and infertility, undergoing either procedure (microsurgery in 49 cases and embolization in 27 cases) was prospectively analyzed preoperatively and postoperatively (at 1, 3, 6, 9 and 12 months). Outcome measures were: semen parameters, pregnancies, pain, side effects, recovery time and overall satisfaction. Subsequently, all patients were contacted by telephone in January 2015 (with a median delay of 4 years after the procedure) in order to determine reproductive events.
RESULTS: Preoperatively, both groups were identical for clinical and biological items. We observed an improvement of sperm concentration at 3, 6, 9 and 12 months (P<0.001, <0.001, 0.012, 0.018, respectively) and sperm motility at 6 months (P=0.002). The sperm concentration was higher at 6 months in PE group (P=0.043). With a median follow-up of 4 years after the procedure, 27 pregnancies occurred (spontaneous pregnancy rate of 32%). There was no difference between procedures on the sperm quality, pregnancy rate and the overall satisfaction. Patients undergoing percutaneous embolization reported a faster recovery time (P=0.002) and less postoperative pain (P=0.007).
CONCLUSIONS: Both procedures give equivalent results regarding sperm quality, pregnancy rate and satisfaction even though recovery seems faster and postoperative pain seems lower after percutaneous embolization.
