Abstract
OBJECTIVES To examine the changes in diagnostic practices and clinical management of patients with 5α-reductase type 2 (SRD5A2) or 17β-hydroxysteroid dehydrogenase type 3 (HSD17B3) deficiency since molecular diagnoses became available. METHODS Clinical, laboratory, and therapeutic data were retrieved from the medical records of 52 patients with a molecular diagnosis of SRD5A2 (n = 31) or HSD17B3 (n = 21) deficiency. Temporal trends regarding age at assessment and initial sex assignment over 1994-2020 were qualitatively analyzed. Age at molecular diagnosis was compared between two subgroups of patients according to their year of birth. RESULTS Fifty-eight percent (n = 30) patients were diagnosed during the perinatal period, 33% (n = 17) during infancy, and 9% (n = 5) during adolescence or adulthood. Over the studied period, the patients' age at initial assessment and diagnosis frankly decreased. The median (range) age at diagnostic confirmation was 10.5 (0-53.2) years for patients born before 2007 and 0.4 (0-9.3) years for those born in 2007 or later (P = 0.029). Genetic testing identified 27 different variants for the SRD5A2 gene (30% novel, n = 8) and 18 for the HSD17B3 gene (44% novel, n = 8). Before 2002, most patients were initially assigned as females (95%, n = 19), but this proportion dropped for those born later (44%, n = 14; P < 0.001). The influence of initial genital appearance on these decisions seemingly decreased in the most recent years. Therapeutic interventions differed according to the sex of rearing. Ten percent (n = 2) patients requested female-to-male reassignment during adulthood. CONCLUSION This study showed, over the past two decades, a clear trend toward earlier diagnosis and assignment of affected newborns as males.

Abstract
STUDY QUESTION Should testicular sperm extraction (TESE) in non-mosaic 47,XXY Klinefelter syndrome (KS) patients be performed soon after puberty or could it be delayed until adulthood? SUMMARY ANSWER The difference in sperm retrieval rate (SRR) in TESE was not significant between the 'Young' (15-22 years old) cohort and the 'Adult' (23-43 years old) cohort of non-mosaic KS patients recruited prospectively in parallel. WHAT IS KNOWN ALREADY Several studies have tried to define predictive factors for TESE outcome in non-mosaic KS patients, with very heterogeneous results. Some authors have found that age was a pejorative factor and recommended performing TESE soon after puberty. To date, no predictive factors have been unanimously recognized to guide clinicians in deciding to perform TESE in azoospermic KS patients. STUDY DESIGN, SIZE, DURATION Two cohorts (Young: 15-22 years old; Adult: 23-43 years old) were included prospectively in parallel. A total of 157 non-mosaic 47,XXY KS patients were included between 2010 and 2020 in the reproductive medicine department of the University Hospital of Lyon, France. However 31 patients gave up before TESE, four had cryptozoospermia and three did not have a valid hormone assessment; these were excluded from this study. PARTICIPANTS/MATERIALS, SETTING, METHODS Data for 119 patients (61 Young and 58 Adult) were analyzed. All of these patients had clinical, hormonal and seminal evaluation before conventional TESE (c-TESE). MAIN RESULTS AND THE ROLE OF CHANCE The global SRR was 45.4%. SRRs were not significantly different between the two age groups: Young SRR=49.2%, Adult SRR = 41.4%; P = 0.393. Anti-Müllerian hormone (AMH) and inhibin B were significantly higher in the Young group (AMH: P = 0.001, Inhibin B: P < 0.001), and also higher in patients with a positive TESE than in those with a negative TESE (AMH: P = 0.001, Inhibin B: P = 0.036). The other factors did not differ between age groups or according to TESE outcome. AMH had a better predictive value than inhibin B. SRRs were significantly higher in the upper quartile of AMH plasma levels than in the lower quartile (or in cases with AMH plasma level below the quantification limit): 67.7% versus 28.9% in the whole population (P = 0.001), 60% versus 20% in the Young group (P = 0.025) and 71.4% versus 33.3% in the Adult group (P = 0.018). LIMITATIONS, REASONS FOR CAUTION c-TESE was performed in the whole study; we cannot rule out the possibility of different results if microsurgical TESE had been performed. Because of the limited sensitivity of inhibin B and AMH assays, a large number of patients had values lower than the quantification limits, preventing the definition a threshold below which negative TESE can be predicted. WIDER IMPLICATIONS OF THE FINDINGS In contrast to some studies, age did not appear as a pejorative factor when comparing patients 15-22 and 23-44 years of age. Improved accuracy of inhibin B and AMH assays in the future might still allow discrimination of patients with persistent foci of spermatogenesis and guide clinician decision-making and patient information. STUDY FUNDING/COMPETING INTEREST(S) The study was supported by a grant from the French Ministry of Health D50621 (Programme Hospitalier de Recherche Clinical Régional 2008). The authors have no conflicts of interest to disclose. TRIAL REGISTRATION NUMBER NCT01918280.

Abstract
AIM To provide practice guidelines about fertility preservation (FP) in oncology. METHODS We selected 400 articles after a PubMed review of the literature (1987-2019). RECOMMENDATIONS Any child, adolescent and adult of reproductive age should be informed about the risk of treatment gonadotoxicity. In women, systematically proposed FP counselling between 15 and 38 years of age in case of treatment including bifunctional alkylating agents, above 6 g/m2 cyclophosphamide equivalent dose (CED), and for radiation doses on the ovaries ≥3 Gy. For postmenarchal patients, oocyte cryopreservation after ovarian stimulation is the first-line FP technique. Ovarian tissue cryopreservation should be discussed as a first-line approach in case of treatment with a high gonadotoxic risk, when chemotherapy has already started and in urgent cases. Ovarian transposition is to be discussed prior to pelvic radiotherapy involving a high risk of premature ovarian failure. For prepubertal girls, ovarian tissue cryopreservation should be proposed in the case of treatment with a high gonadotoxic risk. In pubertal males, sperm cryopreservation must be systematically offered to any male who is to undergo cancer treatment, regardless of toxicity. Testicular tissue cryopreservation must be proposed in males unable to cryopreserve sperm who are to undergo a treatment with intermediate or severe risk of gonadotoxicity. In prepubertal boys, testicular tissue preservation is: - recommended for chemotherapy with a CED ≥7500 mg/m2 or radiotherapy ≥3 Gy on both testicles. - proposed for chemotherapy with a CED ≥5.000 mg/m2 or radiotherapy ≥2 Gy. If several possible strategies, the ultimate choice is made by the patient.

Abstract
Klinefelter Syndrome (KS) patients, defined by a 47 XXY karyotype, have increased risk of fragility fractures. We have assessed bone microarchitecture by high resolution peripheral quantitative CT (HR-pQCT) at the radius and tibia in young KS patients, naïve from testosterone replacement therapy (TRT). Areal bone mineral density (BMD) and body composition were assessed by dual X-ray absorptiometry (DXA). Total testosterone (tT) was measured at baseline. Bone measurements have been repeated after 30 months of TRT. We enrolled 24 KS patients and 72 age-matched controls. KS patients were (mean ± SD) 23.7 ± 7.8 year-old. KS patients had significantly lower relative appendicular lean mass index (RALM) and lower aBMD at spine and hip than controls. Ten patients (42%) had low tT level (≤ 10.4 nmol/L). At baseline, we observed at radius a marked cortical (Ct) impairment reflected by lower Ct.area, Ct.perimeter, and Ct.vBMD than controls. At tibia, in addition to cortical fragility, we also found significant alterations of trabecular (Tb) compartment with lower trabecular bone volume (BV/TV) and Tb.vBMD as compared to controls. After 30 months of TRT, 18 (75%) KS patients were reassessed. Spine aBMD and RALM significantly increased. At radius, both cortical (Ct.Pm, Ct.Ar, Ct.vBMD, Ct.Th) and trabecular (Tb.vBMD) parameters significantly improved. At tibia, the improvement was found only in the cortical compartment. Young TRT naïve KS patients have inadequate bone microarchitecture at both the radius and tibia, which can improve on TRT.

Abstract
BACKGROUND NR0B1 pathogenic variants can cause congenital adrenal hypoplasia or primary adrenal insufficiency in early childhood usually associated with hypogonadotropic hypogonadism. NR0B1 is necessary for organogenesis of the adrenal cortex and to maintain normal spermatogenesis. In humans, restoration of fertility in patients carrying NR0B1 pathogenic variants is challenging. OBJECTIVE The aim of the study was to investigate the clinical, hormonal, histological, spermiological, and molecular genetic characteristics of a cohort of patients with NR0B1 pathogenic variants, monitored for fertility preservation. PATIENTS We included five patients, including four teenagers, with NR0B1 pathogenic or likely pathogenic variants. They all had primary adrenal insufficiency and were receiving replacement therapy with glucocorticoids and mineralocorticoids. Patients received recombinant follicle-stimulating hormone and recombinant human chorionic gonadotropin in order to induce spermatogenesis. Combined gonadotropin treatment was initiated between 13 years and 15 years and 6 months for the four teenagers and at 31 years and 2 months for the only adult. Physical and hormonal assessments were performed just before starting gonadotropin treatment. After 12 months of gonadotropin treatment, physical examination and hormonal assessments were repeated, and semen analyses were performed. If no sperm cells were observed in at least 2 semen collections at 3-month interval, testicular biopsy for testicular sperm extraction was proposed. RESULTS Bilateral testicular volume increased from 8 ml (interquartile range, 6-9) to 12 ml (10-16) after gonadotropin treatment. Inhibin B levels were relatively stable: 110 ng/L (46-139) before and 91 ng/L (20-120) at the end of gonadotropin treatment. Azoospermia was observed in all semen analyses for all cases during gonadotropin treatment. Three patients agreed to testicular biopsy; no mature sperm cells could be retrieved in any. CONCLUSION We characterized a cohort of patients with NR0B1 pathogenic or likely pathogenic variants for fertility preservation by recombinant gonadotropin treatment, which began either at puberty or in adulthood. No sperm cells could be retrieved in semen samples or testicular biopsy even after gonadotropin treatment, indicating that gonadotropin treatment, even when started at puberty, is ineffective for restoring fertility.

Abstract
Background Androgens are well known to be necessary for spermatogenesis. The purpose of this study was to determine Sertoli cell responsiveness to androgens according to age from birth to puberty. Results Testicular tissue samples were studied in a population of 84 control boys classified into seven groups according to age: group 1 (1–30 days), group 2 (1–3 months), group 3 (3–6 months), group 4 (0.5–3 years), group 5 (3–6 years), group 6 (6–12 years), and group 7 (12–16 years). We compared these data with those of 2 situations of pathology linked to androgens: 1/premature secretion of testosterone: 4 cases of Leydig cell tumor (LCT) in childhood; and 2 /defect of androgen receptors (AR): 4 cases of complete form of insensitivity to androgen syndrome (CAIS). In control boys, AR immunoreactivity (ir) in Sertoli cells appeared between 4.6 and 10.8 years of age, Anti-Mullerian Hormone (AMH) ir in Sertoli cells disappeared between 9.2 and 10.2 years of age. Connexin 43 (Cx43) ir in Sertoli cells and histological features of the onset of spermatogenesis appeared between 10.8 and 13,8 years of age. Cx43 ir was significantly higher in 12–16 year-olds than in younger boys. In case of CAIS, no spermatogenesis was observed, both AR and Cx43 ir were undetectable and AMH ir was elevated in Sertoli cells even at pubertal age. In the vicinity of LCTs, spermatogenesis occurred and both AR and Cx43 ir were strongly positive and AMH ir in Sertoli cells was low for age. Conclusions Androgen action on Sertoli cells is required for onset of spermatogenesis and premature androgen secretion by LCT can induce spermatogenesis in the vicinity of the tumor. AR ir appeared earlier than onset of spermatogenesis, with large interindividual variability. The timing and mechanisms of Sertoli cell responsiveness to androgens are important issues for understanding the induction of spermatogenesis at puberty.

Abstract
OBJECTIVES The Francophone Society of Sexual Medicine (SFMS) and the Andrology and Sexual Medicine Committee (CAMS) of the French Association of Urology (AFU) have brought together a panel of experts to develop French recommendations for the management of testosterone deficiency (TD). METHODS Systematic review of the literature between 01/2000 and 07/2019. Use of the method of recommendations for clinical practice (RPC) and the AGREE II grid. RESULTS TD is defined as the association of clinical signs and symptoms suggestive of TD with a decrease in testosterone levels or serum androgen activity. Diagnosis requires a T lower than the reference values in young men on 2 successive assays. Sexual disorders are often at the forefront, and concern the whole male sexual function (desire, arousal, pleasure and orgasm). The most evocative symptoms are: decrease in sexual desire, disappearance of nocturnal erections, fatigue, loss of muscle strength. Overweight, depressed mood, anxiety, irritability and malaise are also frequently found. TD is more common in cases of metabolic, cardiovascular, chronic, andrological diseases, and in cases of corticosteroid, opioid, antipsychotic, anticonvulsant, antiretroviral, or cancer treatment. Since SHBG is frequently abnormal, we recommend that free or bioavailable T is preferred over total T. The treatment of TD requires a prior clinical (DRE, breast examination) and biological (PSA, CBC) assessment. Contraindications to T treatment are: progressive prostate or breast cancer, severe heart failure or recent cardiovascular event, polycytemia, complicated BPH, paternity project. It is possible in cases of sleep apnea syndrome, psychiatric history, stable heart disease, prostate cancer under active surveillance and after one year of complete remission of a low or intermediate risk localized prostate cancer treated in a curative manner. It includes long-term testosterone supplementation and life-style counseling. Treatment is monitored at 3, 6, 12 months and annually thereafter. It is clinical (annual DRE) and biological (total T, PSA, CBC), the most frequent side effect being polyglobulia. CONCLUSION These recommendations should help improve the management of TD.

Abstract
Male infertility affects about 7% of the general male population. Balanced structural chromosomal rearrangements are observed in 0.4-1.4% of infertile males and are considered as a well-established cause of infertility. However, underlying pathophysiological mechanisms still need to be clarified. A strategy combining standard and high throughput cytogenetic and molecular technologies was applied in order to identify the candidate genes that might be implicated in the spermatogenesis defect in three male carriers of different balanced translocations. Fluorescence in situ hybridization (FISH) and whole-genome paired-end sequencing were used to characterize translocation breakpoints at the molecular level while exome sequencing was performed in order to exclude the presence of any molecular event independent from the chromosomal rearrangement in the patients. All translocation breakpoints were characterized in the three patients. We identified four variants: a position effect on LACTB2 gene in Patient 1, a heterozygous CTDP1 gene disruption in Patient 2, two single-nucleotide variations (SNVs) in DNAH5 gene and a heterozygous 17q12 deletion in Patient 3. The variants identified in this study need further validation to assess their roles in male infertility. This study shows that beside the mechanical effect of structural rearrangement on meiosis, breakpoints could result in additional alterations such as gene disruption or position effect. Moreover, additional SNVs or copy number variations may be fortuitously present and could explain the variable impact of chromosomal rearrangements on spermatogenesis. In conclusion, this study confirms the relevance of combining different cytogenetic and molecular techniques to investigate patients with spermatogenesis disorders and structural rearrangements on genomic scale.

Abstract
BACKGROUND The aim of these Association Française d'Urologie (AFU) and Société d'Andrologie de Langue Française (SALF) common recommendations are to provide practice guidelines for the French Urological and Andrological community regarding the evaluation of infertile men. MATERIAL AND METHODS Literature search in PubMed using the keywords "male infertility", "diagnosis", "management" and "evaluation" limited to clinical articles in English and French prior to 1/01/2020. To inform the level of evidence, the HAS grading system (2013) was applied. RESULTS Concerning the evaluation of infertile men, the AFU and the SALF recommend : (1) a systematic interview exploring the family history, the fertility history of the man outside the couple, the patient's personal history that may have an impact on his fertility, lifestyle habits, treatments, symptoms and possible sexual difficulties of the couple; (2) a general physical examination to assess signs of hypogonadism and secondary sexual characters; (3) a scrotal physical examination performed by an urologist or andrologist to assess (i) the testes for volume and consistency, (ii) vas deferens and epididymes for total or partial absence or nodules, and (iii) presence of varicoceles; (4) Performing two semen analyses, according to World Health Organization guidelines, if the first one has at least one abnormaly; (5) a scrotal ultrasound as part of routine investigation, that can be completed with an endorectal pelvic ultrasound according to the clinic; (6) an endocrine evaluation with at least a Testosterone and FSH serum determination; (7) Karyotype analysis in infertile men with a sperm concentration ≤10 106/mL; (8) assessment of Yq microdeletions in infertile men with a sperm concentration ≤1 106/mL; (9) Cystic fibrosis transmembrane conductance regulator gene evaluation in case of suspicion for bilateral or unilateral congenital agenesis of vas deferens and seminal vesicles. The interest of tests analyzing DNA fragmentation (TUNEL, SCSA) is still under investigation. CONCLUSION These guidelines can be applied in routine clinical practice in all infertile men.

Abstract
Globozoospermia is a rare phenotype of primary male infertility inducing the production of round-headed spermatozoa without acrosome. Anomalies of DPY19L2 account for 50-70% of all cases and the entire deletion of the gene is by far the most frequent defect identified. Here, we present a large cohort of 69 patients with 20-100% of globozoospermia. Genetic analyses including multiplex ligation-dependent probe amplification, Sanger sequencing and whole-exome sequencing identified 25 subjects with a homozygous DPY19L2 deletion (36%) and 14 carrying other DPY19L2 defects (20%). Overall, 11 deleterious single-nucleotide variants were identified including eight novel and three already published mutations. Patients with a higher rate of round-headed spermatozoa were more often diagnosed and had a higher proportion of loss of function anomalies, highlighting a good genotype phenotype correlation. No gene defects were identified in patients carrying < 50% of globozoospermia while diagnosis efficiency rose to 77% for patients with > 50% of globozoospermia. In addition, results from whole-exome sequencing were scrutinized for 23 patients with a DPY19L2 negative diagnosis, searching for deleterious variants in the nine other genes described to be associated with globozoospermia in human (C2CD6, C7orf61, CCDC62, CCIN, DNAH17, GGN, PICK1, SPATA16, and ZPBP1). Only one homozygous novel truncating variant was identified in the GGN gene in one patient, confirming the association of GGN with globozoospermia. In view of these results, we propose a novel diagnostic strategy focusing on patients with at least 50% of globozoospermia and based on a classical qualitative PCR to detect DPY19L2 homozygous deletions. In the absence of the latter, we recommend to perform whole-exome sequencing to search for defects in DPY19L2 as well as in the other previously described candidate genes.

Abstract
Beside cytotoxic drugs, other drugs can impact men's fertility through various mechanisms. Via the modification of the hypothalamic-pituitary-gonadal axis hormones or by non-hormonal mechanisms, drugs may directly and indirectly induce sexual dysfunction and spermatogenesis impairment and alteration of epididymal maturation. This systematic literature review summarizes existing data about the negative impact and associations of pharmacological treatments on male fertility (excluding cytotoxic drugs), with a view to making these data more readily available for medical staff. In most cases, these effects on spermatogenesis/sperm maturation/sexual function are reversible after the discontinuation of the drug. When a reprotoxic treatment cannot be stopped and/or when the impact on semen parameters/sperm DNA is potentially irreversible (Sulfasalazine Azathioprine, Mycophenolate mofetil and Methotrexate), the cryopreservation of spermatozoa before treatment must be proposed. Deleterious impacts on fertility of drugs with very good or good level of evidence (Testosterone, Sulfasalazine, Anabolic steroids, Cyproterone acetate, Opioids, Tramadol, GhRH analogues and Sartan) are developed.

Abstract
INTRODUCTION The Klinefelter syndrome (KS) is a genetic condition characterized by an X supernumerary sex chromosome in males. The syndrome is frequently associated with cognitive impairment. Indeed, the different areas of the executive sphere can be affected such as inhibition, cognitive flexibility but also attentional and visual-spatial domain. Social cognition disorders, predominantly on emotional recognition processes, have also been documented. In addition, the syndrome may be associated with psychiatric symptoms. MATERIAL AND METHOD Our study aims to characterize of the various components of social cognition in the SK: facial emotional recognition, theory of mind and attributional style. For this two groups (SK group versus control group) of participants (n=16) matched for age and sociocultural level were recruited. Participants with intellectual disabilities, psychiatric or neurological disorders were excluded. Three social cognition tests were available: the TREF, the MASC, the AIHQ. Neurocognitive functions were assessed by the fNart, the subtest "logical memory" of the MEM-III, the subtests of the two VOSP battery, the d2, the TMT and the Stroop test. RESULTS The SK group had specific social cognition disorders in comparison to the control group. Two emotions in particular were less well recognized: fear and contempt. In addition, the SK group had significantly lower results in theory of mind. Regarding the hostile attribution bias, no significant difference was found. Finally, the results showed correlations between specific attentional disorders and facial emotional recognition. DISCUSSION-CONCLUSION Our study emphasizes social cognition disorders in SK. These disorders could be considered as a phenotypic trait in the syndrome. The interest of better characterizing the cognitive phenotype of genetic disorders that can affect the neurodevelopment is to offer specific cognitive remediation strategies.

Abstract
Until now, complete ex vivo spermatogenesis has been reported only in the mouse. In this species, the duration of spermatogenesis is 35 days, whereas it is 54 days in the rat and 74 days in humans. We performed long-term (until 60 days) cultures of fresh or frozen rat or human seminiferous tubule segments in a bioreactor made of a hollow cylinder of chitosan hydrogel. Testicular tissues were obtained from 8- or 20-day-old male rats or from adult human subjects who had undergone hormone treatments leading to a nearly complete regression of their spermatogenesis before bilateral orchiectomy for gender reassignment. The progression of spermatogenesis was assessed by cytological analyses of the cultures; it was related to a dramatic increase in the levels of the mRNAs specifically expressed by round spermatids, Transition protein 1, Transition protein 2, and Protamine 3 in rat cultures. From 2% to 3.8% of cells were found to be haploid cells by fluorescence in situ hybridization analysis of human cultures. In this bioreactor, long-term cultures of seminiferous tubule segments from prepubertal rats or from adult men allowed completion of the spermatogenic process leading to morphologically mature spermatozoa. Further studies will need to address the way of optimizing the yield of every step of spermatogenesis by adjusting the composition of the culture medium, the geometry, and the material properties of the chitosan hydrogel bioreactors. Another essential requirement is to assess the quality of the gametes produced ex vivo by showing their ability to produce normal offspring (rat) or their biochemical normality (human).

Abstract
CONTEXT Testicular sperm extraction (TESE) in adult patients with nonmosaic 47,XXY provides a sperm retrieval rate (SRR) of approximately 50%. Age is the only significant prognostic factor. Whether TESE should be performed in adolescent patients for sperm cryopreservation remains to be determined. OBJECTIVE The objective of the study was to compare SRR between young (15-23 y) and adult (> 23 y) patients with 47,XXY, and to determine whether previous androgenic treatment had a deleterious effect. DESIGN We designed a prospective comparative study between two groups enrolled in parallel from September 2010 onward. SETTING University hospital. PATIENTS Forty one patients with nonmosaic 47,XXY karyotype and azoospermia were included. Twenty five patients from 15-22 years of age were assigned to the "Young" group, and 16 patients age 23 years or more, to the "Adult" group. INTERVENTION A bilateral testicular open biopsy was performed by a single surgeon. The reproductive biologist who performed TESE was blind to the patient's age. Principal Outcome Measure: The main outcome measure was the SRR. The TESE procedure was considered positive if at least 20 sperm cells could be cryopreserved for intracytoplasmic sperm injection. RESULTS SRR was 13/25 = 52% in the Young group and 10/16 = 62.5% in the Adult group, the difference being nonsignificant (P = .73). Ages were 24.3 ± 7.4 years in the 23 cases of positive TESE, and 23.7 ± 7.4 in the 18 cases of negative TESE, the difference being nonsignificant (P = .42). SRR was 9/17 = 52.9% for patients with and 14/24 = 59.1% for patients without previous testosterone (T) treatment, the difference being nonsignificant (P = .98). CONCLUSIONS According to the present results, performing TESE at a younger age (15-23 y) in patients with azoospermic nonmosaic 47,XXY Klinefelter did not increase SRR relative to adult patients (25-39 y). Previous replacement treatment with moderate doses of T did not seem to be deleterious for the recovery of sperm cells by TESE.

Abstract
Medical optimisation of sperm retrieval in non-obstructive azoospermia is reviewed. Gonadotropin treatment of hypogonadotropic hypogonadism allows obtaining sperms in the ejaculate in about 90% of cases provided the duration of treatment was long enough. TESE is indicated in case of persistent azoospermia at 2 years of continuous treatment. Some publications reported a possible effect of hormonal treatments (FSH, hCG, anti-estrogens, aromatase inhibitors) in primary spermatogenic failure, but mainly in cases selected for their favourable histology and normal hormonal levels. The effect on unselected cases remains doubtful. Conversely, the effect of the treatment of varicoceles is significant. Other medical treatments or advises need further investigations.

Abstract
Until few years ago, Klinefelter syndrome with a homogenous 47,XXY karyotype was considered a model of absolute male sterility. We will discuss first the potential fertility following Testicular Sperm Injection, then the physiopathology of spermatogenic failure and the origin of focal spermatogenesis and risk of aneuploidy in offspring, and third the advantage of searching spermatozoa earlier instead of adult age. The rate of positive sperm extraction seems to be better for younger patients. During childhood, there is a low rate of spermatogonia. The spermagonia, which completes the spermatogenesis, seems resulting from a rare clone of 46,XY gonia, having lost their extra X chromosome. Several arguments suggest that this focal spermatogenesis decreases with age. In addition, androgen treatment, frequently prescribed in case of Klinefelter syndrome, carries a risk of decreasing focal spermatogenesis by lowering gonadotropins. The question arises if it is necessary to expect the sperm cryopreservation before introducing androgen treatment. Further studies are necessary to determine the best age of sperm retrieval in case of Klinefelter syndrome.

Abstract
INTRODUCTION Relations between sexual desire and testosterone are more complex than previously thought particularly in ageing males. METHODS A Medline search of the existing literature utilizing terms testosterone, libido, sexual desire, hypogonadism, and andropause, was performed until January 2012. RESULTS Testosterone is a physiological stimulator of sexual desire. In case of complete hypogonadism, libido is very low and testosterone treatment restores sexual desire. In epidemiological studies, the relationship between testosterone and sexual desire is statistically significant but less strict because of interactions with other factors which decrease both sexual desire and testosterone levels. It is especially the case in ageing males: in addition to a possible late-onset hypogonadism, other etiological factors (health, partnership, socioeconomical and psychological factors) and other sexual dysfunctions (such as erectile dysfunction) must be taken into account. CONCLUSION The decrease of sexual desire is one of the symptoms seen in late-onset hypogonadism. The effect of testosterone replacement therapy is more obvious that testosterone is low and there are no other causes of impaired sexual desire. There is no evidence that testosterone therapy increases the risk of prostate cancer, benign prostatic hyperplasia or promotes the clinical expression of subclinical prostate cancer.

Abstract
The aim of this study was to compare anti-Mullerian hormone (AMH) plasma levels in patients with azoospermia according to the physiopathology. In a prospective clinical study from April 2008 to March 2009 in University Hospital, we measured AMH levels in 49 consecutive patients with azoospermia. AMH plasma levels were correlated with FSH, inhibin B, bioavailable testosterone plasma levels and testicular volume and compared between nonobstructive azoospermia (NOA) and obstructive azoospermia (OA) and within four physiopathological subgroups of NOA: genetic, cryptorchidism, cytotoxic and unexplained. AMH, FSH, inhibin B, bioavailable testosterone plasma levels and testicular volumes were all related to each other. AMH plasma levels were lower in NOA relatively to OA. Lowest values were observed in cases of genetic NOA and on the other hand, the values observed in case of cytotoxic NOA were as high as the values observed in OA. FSH, inhibin B, bioavailable testosterone and testicular volume were not different between genetic and cytotoxic NOA. These results suggest that the decrease in AMH plasma levels is related to the origin of NOA, with low values in genetic NOA and values similar to OA in cytotoxic NOA. Further studies will be useful to understand the fine regulation of AMH production.

Abstract
OBJECTIVE To study a transmissible partial AZFb and -c microdeletion. DESIGN Case report. SETTING Service of Reproductive Medicine, Molecular Biology, CHU Lyon, France. PATIENT(S) A case of oligoasthenospermia with partial spermatogenic failure. Screening for Yq microdeletions revealed the absence of sY143, suggesting an AZFb microdeletion. INTERVENTION(S) Sequence-tagged site mapping indicated that the deletion encompassed a portion of the AZFb and -c region. Genomic DNA from the patient's father gave the same pattern. During the course of these investigations, a pregnancy occurred. On the 46,XY amniocyte and cord blood DNA, the same microdeletion was found. MAIN OUTCOME MEASURE(S) Study of the fine structure of the Y-chromosome and the gene copy number. RESULT(S) The three males of this family have a rearrangement including a deletion encompassing r3 and r4, the palindrome P3, and its boundary regions: u3 and u1 in its distal part. This induced a reduction in DAZ and RBMY1 copy number and complete loss of PRY. CONCLUSION(S) PRY is not indispensable to complete spermatogenesis; and with two RBMY1 and two DAZ copies, complete spermatogenesis can be conserved.

Abstract
During their post-meiotic maturation, male germ cells undergo an extensive reorganization of their genome, during which histones become globally hyperacetylated, are then removed and progressively replaced by transition proteins and finally by protamines. The latter are known to tightly associate with DNA in the mature sperm cell. Although this is a highly conserved and fundamental biological process, which is a necessary prerequisite for the transmission of the male genome to the next generation, its molecular basis remains mostly unknown. We have identified several key factors involved in this process, and their detailed functional study has enabled us to propose the first model describing molecular mechanisms involved in post-meiotic male genome reprogramming. One of them, Bromodomain Testis Specific (BRDT), has been the focus of particular attention since it possesses the unique ability to specifically induce a dramatic compaction of acetylated chromatin. Interestingly, a mutation was found homozygous in infertile men which, according to our structural and functional studies, disrupts the function of the protein. A combination of molecular structural and genetic approaches has led to a comprehensive understanding of new major actors involved in the male genome reprogramming and transmission.

Abstract
OBJECTIVE To evaluate the predictive value of seminal inhibin B and anti-Müllerian hormone (AMH) on the outcome of testicular sperm extraction (TESE) in patients with nonobstructive azoospermia. DESIGN Prospective study. SETTING Reproductive biology department. PATIENT(S) Forty-seven normospermic, 28 oligozoospermic, and 68 azoospermic patients. INTERVENTION(S) Testicular sperm extraction. MAIN OUTCOME MEASURE(S) Seminal inhibin B and AMH measure. RESULT(S) The seminal values of inhibin B and AMH are widely dispersed. Both inhibin B and AMH seminal values are significantly different between the three groups. The average rates of seminal AMH (not inhibin B) differ significantly according to the etiology of the azoospermia. Both seminal markers are correlated. A significant positive correlation could be observed between the seminal inhibin B and the sperm count, but not for AMH. A significant correlation also exists between seminal and serum inhibin B. The predictive value for TESE outcome of each parameter is rather low. Conversely, a logistic regression combining serum FSH, seminal inhibin B, and AMH produced a satisfying area under the curve of 0.985. CONCLUSION(S) Seminal inhibin B and AMH values are proposed. Separately, seminal markers are poor predictors of TESE outcome. A logistic regression model led to a satisfying area under the curve of 0.985.

Abstract
AbstractBackground: Bioavailable testosterone (BT) concentration is considered the best marker for evaluating testicular function in men. The decrease of BT in older men is more pronounced than the decrease in total testosterone because of the parallel increase in sex hormone–binding globulin (SHBG) concentrations. Measurement of BT is therefore crucial for the diagnosis of hypoandrogenism in the aging male population.Methods: We compared BT concentrations measured by a specific RIA after ammonium sulfate precipitation (BTmeas) with those obtained by theoretical calculations (BTcal) in plasma samples from 694 young men (14 to 49 years old) and 51 older men (50 to 81 years old). We based theoretical calculations on Vermeulen’s simplified mass equation using total testosterone and SHBG concentrations.Results: BTcal and BTmeas correlated significantly in young (Pearson r = 0.87) and aging (r = 0.89) men, but the BTcal:BTmeas ratio differed markedly between the 2 groups (2.28 vs 3.48; P <0.001).Conclusions: In men, there is an age-associated discrepancy between calculated and measured BT concentrations. We suggest some hypotheses for the discrepancy, but additional studies will be performed to finally elucidate this difference in results and to determine the most appropriate method for BT measurements in older men.

Abstract
Patients with severe spermatogenesis impairment can now successfully father a child thanks to the use of intracytoplasmic sperm injection (ICSI). In oligozoospermic patients, many studies have reported significantly higher sperm aneuploidy rates and therefore an increased risk of transmitting a chromosomal abnormality via the injection of abnormal spermatozoa. However, the frequency of aneuploidy is highly variable between patients. The aim of the present work was to identify clinical and biological factors, which, together with non-obstructive oligozoospermia, could be predictive of elevated sperm aneuploidies. The sperm aneuploidy rates for chromosomes X, Y, 13, 18 and 21 were assessed in 31 infertile men with well-characterized spermatogenesis impairment, and in a population of control men with proven fertility. The frequency of sperm aneuploidy was compared between several patient subgroups according to their clinical and biological factors. Nearly half of the oligozoospermic males (15/31) had a significantly increased disomy rate for at least one of the five chromosomes compared with that observed in the control population (mean disomy rates + 1.96 standard deviation). Factors significantly associated with higher numbers of aneuploid sperm were cigarette smoking, an elevated follicle-stimulating hormone level, a sperm concentration less than 1 m/mL, and a severe teratozoospermia. Hence, several factors predictive of an increased risk of sperm aneuploidy rates were identified in ICSI male candidates with a non-obstructive oligozoospermia.

Abstract
Spermatogenesis is a complex cellular process regulated by gonadotrophins and local cell-cell interactions. Stem cell factor (SCF) is one of the paracrine factors, produced by the Sertoli cells, involved in the local regulation of spermatogenesis. Measurement of its testicular level is important for addressing its role in testis physiopathology. However, the relative cell composition of experimental and pathological testis samples may lead to misinterpretation in relating SCF mRNA levels to the amount of RNA extracted from the whole tissue sample. Taking into account the relative RNA content of Sertoli cell origin should provide more significant data. In the present study, three sets of experiments were intended for modifying the proportion of RNA of Sertoli cell origin in RNA extracted from whole testis tissue samples: during postnatal development; following methoxy-acetic acid (MAA) administration; and after injecting a long-acting gonadotrophin-releasing hormone agonist (GnRHa). In a first step, we demonstrated clusterin mRNA level stability in purified Sertoli cell preparations between 20 days and adulthood, and following MAA or GnRHa treatment. In a second step, we used a competitive RT-PCR assay to measure SCF and clusterin mRNA levels and expressed the amount of SCF mRNA relative to the amount of clusterin mRNA under the above experimental conditions. The SCF/clusterin mRNA level ratio was found to remain roughly stable from 20 days post-partum to adulthood; i.e. during the development of spermatogenesis. MAA administration led to an overall increase in the SCF/clusterin mRNA level ratio between 7 and 14 days after administration, consistent with the replenishment of the testis with pachytene spermatocytes and round spermatids. Conversely, after long-acting GnRHa injection, the SCF/clusterin mRNA level ratio decreased only slightly from day 21 onward. Hence, the present studies indicate that, under physiopathological conditions, the amount of clusterin mRNA is a good marker of the amount of RNA of Sertoli cell origin in testis samples at day 20 or later; different experimental alterations of spermatogenesis are associated with different patterns of SCF mRNA levels; the relationship between FSH and SCF in vivo is not as simple as that described in vitro.

Abstract
BACKGROUND Recent data emphasized the implication of polymerase gamma (POLG) CAG repeats in infertility, making it a very attractive gene for study. A comparison of POLG CAG repeats in infertile and fertile men showed a clear association between the absence of the usual 10-CAG allele and male infertility, excluding azoospermia. It has also been suggested that the POLG gene polymorphism should be considered as a possible contributing factor in unexplained couple infertility where semen parameters are normal. In this study, we investigated the POLG CAG repeats, in a well-defined population of patients with severe male factor infertility. METHODS We conducted a large study of POLG CAG repeats in 433 infertile and 91 fertile, normozoospermic and healthy males. In all subjects, phenotypic data, including semen parameters, hormonal status and clinical profiles, were available. RESULTS Thirteen 'homozygous mutants' (3%) were found among the 433 idiopathic infertile patients. The follow-up of the 13 'homozygous mutant' resulted in pregnancy for more than half of the couples, through assisted reproductive techniques or even spontaneously. In addition, one 'homozygous mutant' was identified in 91 fertile men (1.1%) CONCLUSION Under our conditions, our study does not confirm any relationship between the polymorphic CAG repeat in the POLG gene and male infertility.

Abstract
Y chromosome microdeletion screening is advised in cases of severely impaired spermatogenesis. Improvements in molecular biological techniques have made diagnosis more accessible in routine analysis. However, Y chromosome microdeletions are not diagnosed in all IVF centres. The aim of the present study was to determine the regulatory (indications, financing) and performance (methods, invoicing) conditions required for this analysis, in France. Microdeletion detection was found to be spreading fast and consistantly. It therefore seems necessary for a consensus to be reached on indications, with a view to a standardized technique, with a common effort of experts in the field. Financial management by the French Health Insurance bodies (Sécurité Sociale) would be an essential step towards routine adoption. Lastly, the answers to our questionnaire revealed a strong demand for information concerning this analysis.

Abstract
There is growing interest in the hormonal changes of the ageing male, particularly in view of the expected growth of the population of males over the age of 50. Current research topics essentially concern androgen decline in the aging male (ADAM), or partial androgen deficiency of the aging male (PADAM), commonly called "andropause" in France. Although progress has been made in our knowledge concerning androgen deficiency of the aging male, it is still incomplete, sometimes confused, and some aspects of androgen replacement therapy remain controversial. The International Society for the Study of the Aging Male (ISSAM) therefore considered it appropriate to propose a series of practical and official guidelines concerning the investigation, treatment and surveillance of late-onset hypogonadism in males. The French translation of these recent international guidelines is presented and discussed in this article.

Abstract
SHBG is the specific plasma transport protein for sex steroid hormones in humans. Plasma SHBG concentration follows a gender dimorphism but varies with nutritional and hormonal status in both sexes. In addition, a genetic influence on SHBG in humans has recently been suggested by family studies. We investigated the relationship between a point mutation (D327N) in SHBG gene exon 8 that delays human SHBG half-life and a pentanucleotide repeat polymorphism [PNRP (TAAAA)(n)] in the SHBG gene 5' untranslated region that influences transcription in vitro, on the one hand, and SHBG levels on the other, in a population of 303 women referred for hirsutism. Of these patients, 154 (51%) met the criteria for polycystic ovary syndrome (PCOS) and 124 (41%) were overweight [body mass index (BMI) > or = 25 kg/m(2)]. The two SHBG gene alleles for D327N substitution, wild-type (W) and variant (v), were identified by restriction fragment length polymorphism in the whole population, and the GeneScan method was used to identify PNRP alleles in 245 subjects. Six alleles of the pentanucleotide motif with six to 11 repeats were present in our population. Plasma SHBG concentration was related to PCOS status, non-SHBG-bound testosterone, BMI, fasting blood glucose level, fasting insulinemia, and D327N allele v. The v allele was associated with higher SHBG levels [36.9 +/- 15.9 nmol/liter for W/v (n = 52) and 43.5 +/- 3.5 nmol/liter for v/v (n = 2)] than was the wild-type W allele [31.1 +/- 16.1 nmol/liter (n = 249); P = 0.039]. Multivariate analysis showed that BMI, PCOS status, and D327N polymorphism influenced plasma SHBG concentrations, each of these parameters contributing independently of the others. Investigating the role of each allele of the TAAAA repeat polymorphism on SHBG levels was more complex because of the number of different genotypes (as many as 18 in our population) and the low frequency of some of them. Moreover, a strong disequilibrium linkage was found between D327N allele v and the eight-TAAAA repeat allele (P < 0.0001). This could mask the effect of the TAAAA repeat polymorphism on SHBG concentration in vivo. Nevertheless, SHBG levels in patients who were homozygous for six repeats (34.9 +/- 16.2 nmol/liter; n = 21) were significantly (P = 0.043) higher than in nine-repeat homozygous patients (21.5 +/- 13.0 nmol/liter; n = 8), and lay between the two for eight-repeat homozygous patients (28.5 +/- 15.8 nmol/liter; n = 44). Delineating the precise role of this PNRP polymorphism will need further investigation in a large healthy population. In summary, although BMI and PCOS status have a major influence on circulating SHBG levels in hirsute women, the present results support the notion that polymorphism(s) within the coding sequence and, potentially, in the regulatory sequence of the SHBG gene are associated with circulating SHBG levels and may represent part of the genetic background of sex steroid hormone activity in humans.

Abstract
OBJECTIVES Recent investigations showed a high prevalence of Y chromosome microdeletions in men with severely impaired spermatogenesis. Screening for these men is recommended prior to assisted reproduction techniques. The aim of this study was to set up a simple method to detect Y deletion in infertile men. First, we tested the feasibility of cytobrush to collect oral cells as source of DNA. Second, we compared a classic PCR corresponding to European recommendations to the Promega kit. PATIENTS AND METHODS Seventeen infertile male patients with previously characterized deletions were included in the present study, after fully informed written consent. Both oral cells and blood were used for DNA extraction. A specific DNA extraction protocol was carried out on the buccal cells. The DNAs were tested for Y deletion screening by two different methods. RESULTS We retrieved between 4 and 10 microg of DNA per brush from buccal cells, allowing several multiplex PCR. The Promega kit detected all the deletions but one: an AZFa deletion was not detected by the two markers of the kit covering this region. In addition, sY130, sY133 and SY153, included in the kit, are not reliable. DISCUSSION AND CONCLUSIONS Buccal cells represent a convenient substitute for blood in testing for Y microdeletions. Both false negative and false positive results were obtained with Promega Kit. On the opposite, PCR according to the European recommendations allow the accurate detection of Y microdeletion in our 17 cases, at a lower cost.

Abstract
BACKGROUND Standard sperm characteristics are poor predictors of the outcome of IVF treatments. On the contrary, sperm genome quality has been emphasized for several years as playing a major role in early embryogenesis, thus in the success of IVF attempt. METHODS Sperm DNA fragmentation from a selected group of 104 couples undergoing assisted reproductive techniques (ART) (IVF: n = 50; and ICSI: n = 54) was measured by TUNEL assay and correlated with semen and ART outcomes. RESULTS A negative correlation was found between sperm characteristics and the proportion of sperm showing DNA fragmentation. For fragmentation >10%, a significant decrease of the fertilization rate was observed. No correlation was found between sperm DNA fragmentation and embryo quality. A high proportion of sperm with fragmented DNA was a pejorative factor to obtain pregnancies when ICSI was performed, but there was no relationship when conventional IVF was performed. CONCLUSIONS The proportion of sperm with DNA fragmentation appears to be potentially useful as a predictor of ICSI outcome, whereas embryo quality based on morphological criteria, appeared unaffected by DNA fragmentation.

Abstract
With age, some men develop symptoms resembling hypogonadism. Several cross-sectional and longitudinal studies have shown a decrease in testosterone levels with ageing in men. This finding has equally been observed in elderly men in good health. Testosterone levels decline progressively as of the thirties, at a rate which remains constant throughout life. While total testosterone levels decrease, sex hormone binding globulin (SHBG) levels on the contrary increase with age, with the result that the levels of free and non-SHBG-bound testosterone (corresponding to the fraction which is bioavailable to target cells) decrease more abruptly than that of total testosterone. Higher LH levels, decreased testosterone response to hCG and less Leydig cells all indicate that ageing induces partial testicular failure. However, the gonadotropic function is also affected in ageing. The hypothalamus-pituitary becomes more sensitive to gonad steroid feedback, LH pulse amplitude decreases, and the LH response to GnRH is blunted compared to the situation in young men. Thus LH level is not a valid index of androgen deficiency in elderly males. None of the androgen-dependent functions (libido, erection, sense of well-being, muscle mass and strength, fat mass, bone mass, erythropoiesis, etc.) are under exclusively androgen control, and there is no elderly male symptom which is completely specific to androgen deficiency. Thus, in elderly men, when clinical symptoms might indicate androgen deficiency, biological confirmation is needed. An assay which is independent of SHBG fluctuations is mandatory. Bioavailable testosterone assay by ammonium sulfate precipitation seems to us to be the optimum method for diagnosing androgen deficiency: it gives a reliable measurement for the testosterone fraction available to target cells, is adapted to clinical practice, and provides results that can be directly compared with current reference values for healthy young men.

Abstract
BACKGROUND Recent investigations emphasized a high prevalence of Y-chromosome microdeletions in men having severely impaired spermatogenesis. Screening of these men is recommended prior to assisted reproduction techniques. METHODS The aim of this study was to define a reliable and efficient method to detect Y-chromosome deletions in infertile men. At first the feasibility of using a cytobrush to collect buccal cells as a source of DNA was tested. Then, a multiplex PCR in accordance with European recommendations (European Andrology Academia: EAA) was compared with a commercial kit. The test population consisted of 18 infertile male patients (with a known Y-deletion). Both buccal and blood cells were used for DNA extraction. A specific DNA extraction protocol was carried out on the buccal cells. RESULTS Between 4-10 micro g of DNA were retrieved per brush, allowing for several PCR attempts. The commercial kit failed to detect an AZFa deletion. Furthermore, markers sY130, sY133 and sY153, included in the kit, are not reliable. Both false negative and false positive results were generated by the commercial kit. CONCLUSION A multiplex PCR performed pursuant to EAA recommendations is proposed. When the testing is conducted with DNA extracted from buccal cells, this protocol is simple, accurate and affordable.

Abstract
Study of the multidrug resistance phenomenon in tumor cell lines has led to the discovery of the product of the multidrug resistance (MDR) type 1 genes, the plasma membrane P-glycoprotein (P-gp) that functions as an energy-dependent pump for the efflux of diverse anticancer drugs. P-gp was also recently identified in normal epithelial cells with secretory/excretory functions and in the endothelial cells of the capillary blood vessels in the brain and the testis. These endothelial cells are key elements of the blood-brain and blood-testis barriers, respectively. The aim of this study, in the rat, mouse, guinea pig, and human, was to determine whether testicular cells other than the capillary endothelial cells could express MDR type I genes. Immunohistochemistry on testicular sections revealed that P-gp is present in interstitial cells in the mouse, rat, and human testes, in early and late spermatids in guinea pig testis, and in late spermatids in the rat, mouse, and human. Reverse transcription-polymerase chain reaction analysis on isolated mouse, rat, and human cells showed that all somatic testicular cells (Leydig cells, macrophages, peritubular cells, and Sertoli cells) and the cytoplasmic lobes from rat late spermatids expressed MDR type I mRNAs, whereas spermatogonia, pachytene spermatocytes, and early spermatids did not. An ontogenesis study in the mouse reveals that type I MDR gene expression begins at 13.5 days postcoitum at the time when the seminiferous cords and the blood vessels appear and are maintained thereafter. Finally, two functional tests on isolated rat cells, the doxorubicin and rhodamine uptake assays, demonstrated that rat testicular macrophages, Leydig cells, peritubular cells, and Sertoli cells displayed a multidrug-resistance activity, whereas spermatogonia, pachytene spermatocytes, and early spermatids did not. Western blot experiments have revealed that a P-gp of 175 kDa is present in the human testis as well as in the rat Leydig cells, testicular macrophages, peritubular cells, and Sertoli cells, but is absent in spermatogonia, spermatocytes, and early spermatids. We conclude that P-gp is involved in the self-protection of the somatic cells and is most probably one of the molecules that confers its functionality to the blood-testis barrier. The absence of expression of MDR type I genes in mitotic and meiotic germ cells probably explains their particular vulnerability to various anticancer drugs. In contrast, expression of the P-gp in the haploid cells most likely reflects the ability of spermatozoa to assume their own antidrug defense.
