RESUMEN
STUDY QUESTION: In a non-commercial national gamete donation programme, do the motivations and personality characteristics of candidate sperm and oocyte donors differ according to their parenthood status? SUMMARY ANSWER: Moderate differences exist between non-parent and parent candidate donors in motivations for gamete donation and representations as well as in personality characteristics. WHAT IS KNOWN ALREADY: Several studies have analysed the motivations and experiences of oocyte or sperm donors, but mainly in countries where gamete donation is a commercial transaction, and very few studies have reported results of personality traits using personality inventory tests. No study has specifically investigated the motivations and personality characteristics of candidate gamete donors according to parenthood status. STUDY DESIGN SIZE DURATION: A prospective study was carried out including 1021 candidate donors from 21 centres (in university hospitals) of the national sperm and egg banking network in France between November 2016 and December 2018. PARTICIPANTS/MATERIALS SETTING METHODS: In total, 1021 candidate gamete donors were included in the study. During their first visit, male (n = 488) and female candidate donors (n = 533) completed a questionnaire on sociodemographic characteristics, their motivations for donation and their representations of donation, infertility and family. Secondly, a NEO Personality Inventory (NEO-PI-R) exploring the Big Five personality traits was completed online. Results were compared between parent and non-parent candidate donors. MAIN RESULTS AND THE ROLE OF CHANCE: Altruistic values were the principal motive for donation irrespective of parenthood status. Reassurance about their fertility or preservation of sperm for future use was more often reported in non-parent than in parent candidate donors. With regard to representation of gamete donation or of the family, independently of their parenthood status, candidate donors more frequently selected social rather than biological representations. Mean personality characteristics were in the normal range. Non-parent candidate donors had higher scores on openness and depression than parents, while parent candidate donors appeared more social than non-parents. LIMITATIONS REASONS FOR CAUTION: The personality characteristics inventory was not completed by all candidate donors included in the study. However, family status did not differ between the two groups (NEO-PI-R completed (n = 525) or not), while the group who completed the NEO-PI-R had a higher educational level. This national study was performed in a country where gamete donation is subject to strict legislation. WIDER IMPLICATIONS OF THE FINDINGS: In a global context where reproductive medicine is commercialized and gamete donor resources are limited, this study found that altruism and social representations of gamete donation and family are the main motivations for gamete donation in a country which prohibits financial incentive. These findings are relevant for health policy and for gamete donation information campaigns. STUDY FUNDING/COMPETING INTERESTS: Grant from the Agence de la Biomédecine, France. The authors have nothing to disclose related to this study. TRIAL REGISTRATION NUMBER: N/A.
RESUMEN
Case series have suggested that pneumococcal endocarditis is a rare disease, mostly reported in patients with co-morbidities but no underlying valve disease, with a rapid progression to heart failure, and high mortality. We performed a case-control study of 28 patients with pneumococcal endocarditis (cases), and 56 patients with non-pneumococcal endocarditis (controls), not matched for sex and age, during the years 1991-2013, in one referral centre. Alcoholism (39.3% versus 10.7%; p <0.01), smoking (60.7% versus 21.4%; p <0.01), the absence of previously known valve disease (82.1% versus 60.7%; p 0.047), heart failure (64.3% versus 23.2%; p <0.01) and shock (53.6% versus 23.2%; p <0.01) were more common in pneumococcal than in non-pneumococcal endocarditis. Cardiac surgery was required in 64.3% of patients with pneumococcal endocarditis, much earlier than in patients with non-pneumococcal endocarditis (mean time from symptom onset, 14.1 ± 18.2 versus 69.0 ± 61.1 days). In-hospital mortality rates were similar (7.1% versus 12.5%). Streptococcus pneumoniae causes rapidly progressive endocarditis requiring life-saving early cardiac surgery in most cases.

STUDY QUESTION: In which cases is freezing of ejaculated sperm indicated before ICSI? SUMMARY ANSWER: Sperm freezing should be performed only when out of two analyses at least one total sperm count in the ejaculate is lower than 10(6). WHAT IS KNOWN ALREADY: Due to variations in individual sperm parameters, in cases of severe oligozoospermia there is a risk of absence of spermatozoa on the day of ICSI, leading to cancellation of the attempt. Sperm freezing can avoid this problem but little is known of the parameters governing the decision to freeze sperm or not. STUDY DESIGN, SIZE, DURATION: This retrospective study included 247 men who underwent sperm cryopreservation to prevent the risk of azoospermia on the day of ICSI, from 2000 to 2012. PARTICIPANTS/MATERIALS, SETTING, METHODS: Receiver operating characteristic curve analysis was used to define the threshold value. The lowest total sperm count per ejaculate was studied as a predictive factor for the use of frozen sperm in a total of 593 ICSI attempts. Moreover, 2003 patients who had at least 4 semen analyses for andrological diagnosis have been studied to evaluate the reproducibility of sperm count. To evaluate the psychological impact of sperm freezing, a questionnaire was administered to 84 men who attended for sperm cryopreservation between June and December 2014. The cost of sperm freezing was analysed according to the French prices. MAIN RESULTS AND THE ROLE OF CHANCE: When at least one total sperm count was <10(5) the risk of azoospermia in at least one ICSI attempt was 52% (34/66) versus 3% (5/181) when all counts were ≥10(5) (P < 0.0001). However, the study of the reproducibility of pre-ICSI semen analyses has shown wide variations among ejaculates, and therefore sperm freezing is recommended when one analysis from at least two, showed a sperm count <10(6). Such a policy could allow a saving of about 70 000 by avoiding unnecessary sperm freezings. The psychological impact of sperm freezing was good since >70% of men had positive feelings about this technique. LIMITATIONS, REASONS FOR CAUTION: This was a fairly short-term study and preservation of future fertility was not assessed. It appeared impossible to find a threshold that would predict the risk of azoospermia with 100% accuracy. Therefore there is still a risk of absence of spermatozoa on the day of ICSI despite a good negative predictive value when no total sperm count was lower than 10(5). WIDER IMPLICATIONS OF THE FINDINGS: These data suggest that sperm freezing should be proposed when total sperm count is lower than 10(6) to avoid cancellation of the ICSI attempt due to azoospermia.

OBJECTIVES: Sexuality is a fundamental part of the life of the individual and the couple particularly sensitive to the crisis that is infertility. The objective of this review is to describe sexual disorders that may be involved in infertility as well as sexual dysfunctions that can appear during medically assisted reproduction. MATERIAL AND METHODS: We performed a literature reviewed from Medline Database and selected 27 articles. RESULTS: Sexual problems are common in infertile couples. Sometimes primary they need to be assessed before the process of assisted reproduction. Mostly secondary (erectile dysfunction, hypoactive sexual desire, decreased sexual activity ), they must be explained and be sought throughout the diagnostic and therapeutic process. A multidisciplinary approach integrating sexological adapted to the specific torque is required and may extend beyond the birth or adoption of the child. CONCLUSIONS: In the treatment for infertility it is important to systematically open discussion on issues of sexuality, and to evaluate the significance and severity of sexual dysfunction. Finally, in some cases it is necessary to help patients rebuild their sexuality as a source of pleasure to the end of the period of assisted reproduction.

Klinefelter's syndrome (KS) affects one in 600 men and Turner's syndrome (TS), one in 2500 women. These 2 diseases are the most sex chromosome disorders characterized by one extra X in the SK male (47XXY) and the loss of an X in the girls with ST (45 X). Their common characteristic is the gonadal dysgenesis, which is the main cause of male or female infertility. Called "the forgotten syndrome", KS is under-diagnosed because apart from the large size, there are no dysmorphic features, along with a great ignorance of cognitive and language disorders in children. There are often comorbidities that lead to diagnosis such as autoimmune diseases or metabolic syndrome. TS is often diagnosed by the short stature. Management of Turner's girls has profoundly changed with Growth hormone therapy. There is an international consensus for a better management of associated diseases such as ORL, cardiac, renal, hepatic, autoimmune and metabolic diseases. Prenatal diagnosis allows early detection and management of cognitive deficiencies and of associated diseases.

This study was designed to investigate the in vitro effects of didanosine, zidovudine, saquinavir and indinavir, commonly used in highly active antiretroviral therapy, on human sperm fertility parameters. Thirty semen samples from healthy men were collected and prepared by gradient density method. Aliquots of 90% fractions with >80% motile spermatozoa were incubated for 1, 3, and 6h with different concentrations of the antiretroviral drugs (20, 40, and 80 µg/ml). Sperm motility was evaluated by computer assisted sperm analysis system. Sperm mitochondrial potential was evaluated using 3,3'-dihexyloxacarbocyanine iodide (DIOC(6)) and the acrosome reaction was examined using pisum sativum agglutinin method. A dose-dependent decrease in sperm motility was observed with saquinavir. Saquinavir also induced a significant time and dose-dependent decrease in mitochondrial potential and an increase in spontaneous acrosome reaction. These findings indicate that, in vitro, higher doses of saquinavir have adverse effects on sperm motility, mitochondrial potential and acrosome reaction.

Assisted Reproductive Technologies for serodiscordant couples with HIV-infected male partner has been possible since 2000 in French centres such as the CECOS in Toulouse. From the outset, couples in the program meet psychologists or psychiatrists. In the first instance, the results from 40 psychologist led interviews with serodiscordant couples held at the CECOS in Toulouse, identified several challenging ideas. Couples who plan to have children were in a stable long-term relationship and both were involved in managing the illness. Medically assisted procreation awakens in the women a strong desire for children and enables the couples to make plans for the future. But it also reminds the men of their reliance on medical assistance because of the demands made by the medical program, and in case of failure it can destabilise the couples' way of coping with HIV. Subsequently, interviews with 12 couples during pregnancy revealed the overbearing presence of the illness, despite the imminent birth of the desired child. In their responses, women express their anxiety concerning the risk of contamination, and the defences that the men had built up to cope with HIV appeared destabilised, now that the idea of their death is rekindled.

Serodiscordant couples whose man is infected by human immunodeficiency virus have actually induced sterility by condom use. Since 2001, in France, assisted reproduction in serodiscordant couples has been facilitated thanks to the decree of 10th May 2001. In spite of the immense social and scientific advances in Assisted Reproductive Techniques, in such couples, limitation of care remains in certain cases. This study reviews current practices in France and other countries. Limits due to present reproductive and virological methods or legal conditions are underlined. In agreement with current scientific knowledge we suggest new modalities of reproductive care in serodiscordant couples with HIV infected men.

Recent progress in reproductive biology has improved comprehension physiology of the spermatozoa and on the fertilization mechanisms. This new knowledge has carried out the elaboration of tests on male fertility based on sperm genomic integrity. This review presents some of these techniques and brings a reflexion element on the application and use of sperm DNA integrity in the investigation of male fertility. The single cell gel electrophoresis (COMET assay), Sperm Chromatin Structure Assay (SCSA), In Situ Nick Translation (NT: Nick Translation) and Terminal Uridine Nick-End Labelling (TUNEL assay) are actually the most currently used techniques for the measure of sperm DNA integrity in research clinic. From a certain point of view, TUNEL assay, SCSA, COMET assay and NT assay are complementary. The TUNEL and COMET can measure single and double strand breaks of DNA, the SCSA can detect the abnormalities in the chromatin compaction and the NT assay can detect the single strand breaks of DNA. The exact origin of sperm DNA fragmentation is not established yet. However, several mechanisms have been proposed: defect in the chromatin compaction during spermiogenesis; reactive oxygen species production by immature spermatozoa; apoptosis during spermatogenesis. It becomes important to consider the possible consequences of the oocyte fertilization by a spermatozoon having a high degree of DNA fragmentation. The use in routine of some of these tests must however pass by a standardization of the inter laboratory protocols and obviously, by the establishment of both in vivo and in vitro discriminating threshold values in order for these tests to present a good predictive value for pregnancy outcome.

Testicular cancer is the most common neoplasia occurring in the young male population. The PEB (cisplatin, etoposide and bleomycin) adjuvant chemotherapy usually proposed after orchidectomy in non seminomatous tumours, and in metastatic seminomas, has improved the long-term survival of these patients. Following an azoospermic period, sperm cell recovery is generally observed after treatment delivery, but little is known about the genetic consequences on these new spermatozoa. To estimate the chromosomal consequences of this chemotherapy on sperm cells during the period of recovery of spermatogenesis, sperm cell aneuploidy was studied in testicular cancer patients, at 6-18 months after PEB adjuvant chemotherapy delivery, using fluorescence in-situ hybridization (FISH) of chromosomes 7, 16, 18, X and Y with specific DNA probes. A significant increase in the frequency of diploidy and disomy for chromosomes 16, 18 and XY was observed in treated patients compared with a healthy control group. Spermatozoa aneuploidy occurring during the spermatogenesis recovery period might be a possible side effect of the PEB regimen. Thus, practitioners should be advised to provide counselling about the need for an appropriate duration of contraception. Moreover, genetic counselling should be offered in cases of pregnancy occurring soon after the end of chemotherapy.

OBJECTIVE: To evaluate relationships between the phenotypic and genotypic characteristics of patients with congenital bilateral absence of the vas deferens (CBAVD). DESIGN: Retrospective study. SETTING: A university hospital urology-andrology department. PATIENT(S): Forty-one men with CBAVD. INTERVENTION(S): CBAVD was diagnosed during surgical and/or ultrasound exploration of the vasa deferentia (VD) (n = 39), or on the basis of impalpable scrotal VD (n = 2). MAIN OUTCOME MEASURE(S): History, clinical and seminal characteristics, and cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations including IVS-8 polyT analysis. RESULT(S): A palpable scrotal vas deferens was present as a fibrous cord or nonpermeable duct in 13% of patients undergoing surgical exploration. Seminal vesicles were bilaterally absent in 28% of patients. No CFTR gene mutation or 5T allele was detected in 24.5% of the patients. Two CBAVD patients with renal agenesis carried a CFTR gene mutation (DeltaF508/5T-9T and R117G/7T-9T). CBAVD patients who have both a semen volume of < or =1.0 mL and a semen pH of < 7.0 have a significantly higher risk of severe CFTR gene mutation (OR = 9.12 [95% CI = 1.81-49.50]). CONCLUSION(S): A palpable scrotal vas deferens was found in 13% of CBAVD patients. Semen volume of < or =1.0 mL and semen pH of < 7.0 in CBAVD patients were associated with a higher risk of severe CFTR gene mutations. Patients with CBAVD and renal agenesis should be screened for CFTR gene mutations before assisted reproductive techniques are used.

BACKGROUND: Use of a motile spermatozoa isolation process was assessed for reducing the transmission of HIV and hepatitis C virus (HCV) during artificial insemination in HIV-serodiscordant couples in which the man is infected. PATIENTS: Thirty-two HIV-1-infected clinically asymptomatic men, having a median CD4 cell count of 396 x 10(6)/l and a median blood plasma HIV-1 RNA content of 414 copies/ml. Of these, 16 were infected with both HIV and HCV. METHODS: Motile spermatozoa were isolated from 51 semen samples by density gradient and 'swim-up'. HIV-1 and HCV genomes were detected and quantified in the blood plasma and seminal plasma, and detected in seminal cell fractions obtained during spermatozoa isolation. RESULTS: HIV-1 RNA was detected in 30% of seminal plasma samples. HIV-1 genomes were found in 18% of seminal cell samples, but in none of the motile spermatozoa fractions after 'swim-up'. There was no correlation between the HIV-1 RNA concentrations in the blood and seminal plasma. HIV-1 genome was detected intermittently in patients who gave more than one sample. HCV RNA was detected in 20% of seminal plasma samples from HCV viraemic patients, but in no seminal cells or motile spermatozoa fractions. CONCLUSIONS: Purification of motile spermatozoa by density gradient plus 'swim-up' reduced the HIV-1 and HCV genomes in the semen of infected individuals to undetectable levels. This method, associated with a standardized virus assay, could be useful for serodiscordant couples (males infected) who wish to have children.

The aim of the present study was to assess variability in the evaluation of human sperm concentration, motility and vitality. Technicians and biologists from 10 teams involved in multicentre studies on semen quality attended the same laboratory, each team using its own methods and equipment to analyse the same semen samples. Inter-individual variability was assessed from 17 fresh semen samples of varying quality. Intra-individual variability was assessed from pools of frozen samples for sperm concentration and motility and stained smears for vitality with three blind evaluations by sample and smear. The mean inter-individual coefficients of variation were 22.9, 21.8 and 17.5% for sperm concentration, motility and vitality respectively. There was no statistical difference among participants for sperm concentration assessment, but significant differences for both motility and vitality (both P: < 0.05). The mean intra-individual coefficients of variation were 15.8, 26.2 and 13.1% for sperm concentration, motility and vitality respectively, with marked differences between expert and novice participants: concentration 9.8% versus 28.0%; motility 22.8% versus 33.0%; and vitality 10.0% versus 19.3%. The present data confirm the need for external quality control schemes for diagnostic purposes, and indicate their utmost importance in multicentre studies on semen quality.

Several recent studies have reported a gradual decline in sperm production in men. Endocrine disrupters as well as lifestyle have been suggested as risk factors. One lifestyle factor that may affect human fertility is driving a vehicle for a prolonged period. Several authors have suggested that driving position may increase the scrotal temperature. In order to validate this hypothesis we conducted continuous monitoring of scrotal temperature in real conditions, i.e. in men driving a car for a prolonged period. Nine volunteer men were asked to walk outside for 40 min and then to drive a car for 160 min. Scrotal temperatures were measured from thermocouples and values recorded every 2 min on a portable data recorder. Scrotal temperature increased significantly (P < 0.0001) in driving posture after 2 h of driving, reaching a value 1.7-2.2 degrees C higher than that recorded while walking. This link between driving position and increased scrotal temperature indicates a potential exposure of male reproductive function to lifestyle factors.

Several lines of evidence indicate that cyokines are involved in male fertility. They are secreted by different parts of the male genital tract and may exert effects on steroidogenesis, spermatogenesis and sperm functions. We measured the concentrations of interleukins (IL-beta, IL-2, IL-6) and those of interleukin soluble receptors (sR IL-2, SR IL-6) in semen of fertile subjects (n = 21) and of patients with a range of andrological diseases (n = 119). The seminal concentrations of cytokines were analysed according to semen parameters as well as to the blood hormonal profiles of follicle stimulating hormone, luteinizing hormone and testosterone. An increase of IL-1beta was observed in the group of patients with infertility. No difference was found between the different subgroups defined on the basis of progressive motility, percentage of abnormal forms and diagnosis of infection. The seminal cytokine concentrations were independent of the blood hormonal status. Our data suggest that the determination of interleukins (-1beta, -2 and -6) or interleukin soluble receptors (sR IL-2, sR IL-6) in human spermatozoa does not provide convenient information in male routine infertility work-up.

Thirty-three patients with azoospermia of apparently excretory origin underwent surgery for epididymis-deferens anastomosis and/or epididymal sperm puncture. Pathology examinations of the epididymal fluid and biopsies of the testicles or epididymis were performed at surgery. Based on the clinical presentation, sperm results and per-operative findings, patients were divided into six groups by etiology: idiopathic azoospermia (n = 5), post-infectious azoospermia (n = 15), agenesia of the excretory (n = 6) or secretory (n = 3) ducts, vasectomy (n = 2), and obstruction of the ejaculatory ducts (n = 2). Peroperative identification of spermatozoa at epididymal puncture or biopsy was statistically more frequent in patients with agenesis of the excretory ducts than in patients with post-infectious or idiopathic azoospermia. Biopsies of the testicle led to the diagnosis of secretory azoospermia in 3 cases and revealed a functional parenchyma in all the other groups of patients. Epididymis-deferens anastomosis was performed in 45% of the cases and was successful in 13%. Rate of fertility with the intracytoplasmic sperm injection was 33%; there was no difficulty in using fresh or frozen sperm. Clinical pregnancy was continued to term with frozen sperm. This study confirms that testicular function is preserved in excretory azoospermia. With or without epididymis-deferens anastomosis, epididymal spermatozoa can generally be preserved for later use. Couples should however be counselled on the delays to contraception which may vary from months to years.

The authors treated 9 patients with rheumatoid arthritis by plasma exchange. In the 5 cases with purely joint involvement, the treatment was not effective, with one exception. In the 4 other cases, with polyneuropathy and vasculitis, plasma exchange resulted in a rapid regression of the symptoms. Thus cases of polyneuropathy and vasculitis due to rheumatoid arthritis are good indications for treatment by plasma exchange.
