Abstract

Abstract Background In 15–49 years-old men, the main cancers are testicular cancer (TC) and lymphomas (L): freezing of ejaculated sperm is primarily used for male fertility preservation (FP) before cancer treatment. Our objective was to analyze the French FP rate in 15–49 years-old men diagnosed with TC or L in 2018. We designed a national descriptive cross-sectional study of sperm banking rate in men with a diagnosis of TC, Hodgkin L (HL) or non-Hodgkin L (NHL). From the French National Cancer Institute (INCa) 2018 data, we extracted the estimated incidence of TC and L in metropolitan France. From the 2018 activity report of CECOS network (Centers for Study and Banking of Eggs and Sperm), we extracted the number of men with TC or L who banked ejaculated sperm. We estimated the proportion of 15–49 years-old men diagnosed with TC or L who banked sperm. Results Among 15–49 years-old men, INCa estimated 38,048 new cancer diagnoses in metropolitan France in 2018: 2,630 TC and 3,913 L (943 HL and 2,970 NHL). The CECOS network provided data from 26/27 metropolitan centers (96% response rate): 1,079 sperm banking for men with TC, 375 for HL and 211 for NHL. We estimated that the 2018 sperm banking rate in France was 41% for TC, 40% for HL, and 7% for NHL. Conclusions To our knowledge, our paper is the first cross-sectional study with multicenter and national data analyzing FP rate in cancer men: it suggests an efficient pathway for men to FP before cancer treatment, compared to previously published studies. Although sperm banking rate in 15–49 years-old men could definitely be improved, further studies should evaluate the information given to patients before gonadotoxic treatments, the factors associated with the absence of sperm banking and whether this lack of referral induces a loss of chance for these men.

Abstract

OBJECTIVES: The etiology of testicular germ cell tumors (TGCT) is suspected to be related to prenatal environmental risk factors. Some solvents have potential endocrine disrupting or carcinogenic properties and may disrupt male genital development in utero. The aim of this study was to examine the association between parental occupational exposure to solvents and TGCT risk among their offspring. METHODS: A French nationwide case–control study, TESTIS included 454 TGCT cases and 670 controls frequency-matched on region and 5-year age strata. Participants were interviewed via telephone and provided information on parental occupations at birth. Job-exposure matrices (JEM) developed in the French Matgéné program were used to assign exposure to five petroleum-based solvents, five solvents or groups of oxygenated solvents, and five chlorinated solvents. Odds ratios (OR) for TGCT and 95% confidence intervals (CI) were estimated using conditional logistic regression, adjusting for TGCT risk factors. RESULTS: Occupational exposure to at least one solvent during the year of their son’s birth was 41% among fathers and 21% among mothers. Paternal exposure to at least one solvent showed OR 0.89 (95% CI 0.68–1.15). Exposure to perchloroethylene (OR 1.41, 95% CI 0.55–3.61), methylene chloride (OR 1.13, 95% CI 0.54–2.34) and diesel/kerosene/fuel oil (OR 1.17, 95% CI 0.80–1.73) disclosed OR >1 but with low precision. Our results suggest a possible modest increase in non-seminoma risk for sons whose fathers were highly exposed to trichloroethylene (OR 1.44, 95% CI 0.79–2.63). Maternal exposure to at least one solvent showed OR 0.90 (95% CI 0.65–1.24). When stratifying by birth year, men born in the 1970s experienced an increased TGCT risk following maternal exposure to fuels and petroleum-based solvents (OR 2.74, 95% CI 1.11–6.76). CONCLUSION: Overall, no solid association was found between parental occupational exposure to solvents and TGCT risk. The association found with maternal occupational exposure to fuels and petroleum solvents among older men needs further investigation.

Abstract

BACKGROUND Many studies reported that reproductive desire could be high among transgender individuals. In France, fertility preservation and sperm donation were very little proposed to transgender individuals until recently, mainly because the Bioethics Law allows the use of assisted reproductive technologies only in infertile couples and prohibits surrogacy. OBJECTIVES To evaluate the distribution of care on the French territory concerning fertility preservation and sperm donation in transgender individuals. MATERIALS AND METHODS A multicentric national survey was carried out between January 2019 and October 2020 in 28 assisted reproductive technology centres of the French CECOS (Centres d'Etudes et de Conservation des Oeufs et du Sperme) network. Each centre was questioned to find out how many transgender individuals came, were informed and cared for fertility preservation and sperm donation. RESULTS Concerning fertility preservation, 71.4% of centres received transgender individuals and performed gamete cryopreservation; 581 transgender individuals consulted for fertility preservation. Transgender women were more likely to desire (p

Abstract

International audience; Introduction - Turner syndrome is one of the most frequent chromosomal abnormalities in women, with a prevalence estimated to be 1 of 2500 live birth. Pregnancy in women with Turner syndrome is known to be at high risk, whether it is spontaneous or after oocyte donation, because of miscarriages and potential cardio-vascular complications which can be life-threatening. All of these patients should therefore be screened with a comprehensive cardio-vascular assessment before pregnancy, and have a close follow-up during and after pregnancy.Patients and methods - It is a retrospective study, conducted in 10 of the 27 French oocyte donation centers between 2012 and 2016, on all the patients presenting with Turner syndrome included in an oocyte donation program.Results - 151 embryo transfers were realized in 73 patients, resulting in 39 pregnancies. Among these pregnancies, 24 children were born healthy, 11 spontaneous miscarriages, 3 voluntary abortions, 1 extra-uterine pregnancy and 1 maternal death from non-cardio-vascular origin occurred. Pregnancies were complicated by gravid arterial hypertension in 28.2% of cases, preeclampsia in 10.3% of cases, and gestational diabetes in 7.7% of cases.Conclusion - This study bring out obstetrical complications of the same magnitude than the ones described in the literature. Lead over a period of 4 years, in 10 French oocyte donation centers, it doesn't reveal any cardio-vascular complications, conversely to other studies published before French and American recommendations. This study reinforces the usefulness of specific recommendations for the care of these particular patients.

Abstract

The purpose of the present multicenter study was to investigate whether an artificial insemination with donor sperm (AID) procedure after intra-couple intracytoplasmic sperm injection (ICSI) failure offers a significant chance of pregnancy and to identify prognostic factors for pregnancy after an AID procedure. An eleven-year retrospective multicenter study was conducted among 13 Centre d'Etude et de Conservation des Oeufs et du Sperme (CECOS) centers. A total of 319 couples having undergone an AID procedure after intra-conjugal ICSI failure were included in this study; a total of 1,159 AID and 1,011 intra-conjugal ICSI cycles were performed. Among the prognostics parameters, the parity and the embryo quality could not be adequately addressed, therefore the parity was not included in the statistical analysis and the embryo quality has been presented as preliminary observations. The pregnancy rate per cycle was 12.0% (139/1,159) and the overall AID pregnancy rate per couple was 43.6% (139/319). Normal or oligoasthenoteratozoospermia (OAT) semen and women aged 34 years or above at the time of AID procedure obtained the lowest AID clinical pregnancy rate. Azoospermia or cryptozoospermia semen and women aged below 34 years obtained the highest AID clinical pregnancy rate. In conclusion, the transition to the AID procedure after intra-conjugal ICSI failure allows such couples to obtain a pregnancy, however after each ART failure AID transition should be proposed according to the woman's age and sperm characteristics.AID: artificial insemination with donor sperm; ICSI: intracytoplasmic sperm injection; CECOS: Centre d'Etude et de Conservation des Oeufs et du Sperme; OAT: oligoasthenoteratozoospermia; IVF: in vitro fertilization; ART: artificial reproductive technology; β hCG: beta human chorionic gonadotrophin; SD: standard deviation; OR: Odds ratio.

Abstract

Objective To report a child with Beckwith-Wiedemann syndrome (BWS) born after assisted reproductive technology (ART) to an HIV serodiscordant couple. Design Case report. Setting Academic medical center. Patient(s) A child with BWS born after ART to an HIV serodiscordant couple. Intervention(s) Assisted reproductive techniques. Main Outcome Measure(s) ART and HIV. Result(s) Since 2003, it has been suggested that there is an association between ART and BWS, which is a congenital overgrowth syndrome characterized by macrosomia, macroglossia, visceromegaly, umbilical and abdominal wall abnormalities, and an increased risk of developing embryonal tumors in childhood. It is a multigenic disorder resulting from genetic or epigenetic alterations of genes on chromosome 11p15. Methylation errors account for 50%–60% of sporadic cases and almost 100% of cases born after ART. We report the birth of a child diagnosed with BWS arising from an ART cycle to an HIV serodiscordant couple with no history of infertility. This case cannot constitute conclusive evidence but it raises various questions. Conclusion(s) Assisted reproductive technology seems to be in the causal pathway but a male/female factor or an iatrogenic factor is also possible.

Abstract

Objective To determine the feasibility of fertility preservation in adolescent males with cancer. Design Large multicenter retrospective study of male patients ≤20 years from 23 centers of a national network of sperm banks over a 34-year period. Setting Sperm banks. Patient(s) A total of 4,345 boys and young men aged 11 to 20 years. Intervention(s) Age, cancer diagnosis, feasibility of sperm banking, and sperm parameters. Main Outcome Measure(s) Description of patients, and success of their fertility preservation. Result(s) We observed a mean yearly increase in referred patients of 9.5% (95% confidence interval, 9.1%–9.8%) between 1973 and 2007. Over the study period, the percentage of younger cancer patients who banked their sperm increased, especially in the 11–14 year age group, rising from 1% in 1986 to 9% in 2006. We found that 4,314 patients attempted to produce a semen sample, 4,004 succeeded, and sperm was banked for 3,616. The mean total sperm count was 61.75 × 10 6 for the 11–14 year age group, and 138.81 × 10 6 for the 18–20 year age group. It was noteworthy that intercenter variations in practices involving young patients seeking to preserve their fertility before cancer therapy were observed within this national network. Conclusion(s) Our results emphasize the need for decisive changes in public health policy to facilitate the access to reproductive health-care for young cancer patients.
