RESUMO
OBJECTIVE: To assess the impact of hepatitis B virus (HBV) infection in women on in vitro fertilization (IVF) outcomes. METHODS: An observational monocentric case-control cohort study conducted between 2012 and 2019 compared the outcomes of the first cycle of IVF between 64 woman infected with HBV and 128 seronegative controls. Frozen embryos transfers made within 18 months of the puncture were included. The exclusion criteria were severe infections, viral co-infection in women, any viral infection in their spouse, or lack of fresh embryo transfer. The matching was performed according to age, primary infertility or secondary, conventional or intracytoplasmic injection IVF technique and date of attempt. The main analysis focused on cumulative live births rates (LBR). RESULTS: The clinical and ovarian stimulation characteristics were comparable except for a longer period of infertility in the HBV group. The LBR in the HBV group, when compared to controls, was not different after transfer of fresh (14.06 vs. 25.00% P=0.08) or frozen embryos (4.17 vs. 18.92% P=0.08), but significantly decreased in cumulative analysis (15.63 vs. 35.94% P=0.003). HBV infection was negatively associated with LBR in multivariate analysis OR=0.38 (95% CI 0.14-0.92) P<0.05. The implantation rate was lower in the HBV group versus controls, in fresh (14.89 vs. 27.72% P=0.02) and frozen (3.03 vs. 21.65% P=0.01) embryo transfers. CONCLUSION: This study suggests a negative impact of HBV infection in women on the cumulative LBR after IVF.

INTRODUCTION: In some studies, early pregnancy loss (EPL) rate is higher with artificial cycle (AC) endometrial preparation for frozen-thawed embryo (FET) transfer than with other protocols, even though pregnancy rates are similar. An inadequate luteal phase support could explain these findings. The aim of this study was to compare, among the patients who had a pregnancy after FET with AC endometrial preparation, serum progesterone (PG) levels between those who experienced an EPL or an ongoing pregnancy. MATERIAL AND METHODS: A monocentric retrospective cohort study, conducted at a University affiliated fertility center, studied 130 FET cycles with AC endometrial preparation between June 2016 and July 2017. Serum PG rates were compared according to reproductive outcomes and to endometrial preparation protocol on day 10 or 12 after FET (PG0) according to the embryo stage, and every 48h in case of pregnancy (i.e. PG1; PG2). RESULTS: Among patients who had a pregnancy after FET with AC (n=33), serum PG levels were higher in case of an ongoing pregnancy than EPL, only significantly at PG1 (PG0 12.4ng/mL [7.5-14.6] vs 8.2ng/mL [6.0-13.0], p= 0.320; PG1 15.0 ng/mL [14.0-15.9] vs 8.5ng/mL [5.9-13.8], p= 0.048). DISCUSSION: We found that serum PG level was lower in women experiencing early pregnancy loss after FET with AC endometrial preparation, potentially reflecting a lack of appropriate luteal phase support with PG. A cycle AC test, monitoring serum PG levels after its steady state, could detect this lack of PG, allowing physicians to adapt PG supplementation.
RESUMO
With the use of antiretroviral therapy, HIV transmission from mother to fetus and between sexual partners has been significantly reduced, successively allowing pregnancy, then assisted reproductive technologies, and targeted unprotected sex among couples living with HIV. Since first French Morlat report in 2013, natural procreation is now possible under certain conditions for these couples living with HIV and the use of assisted reproductive technologies is increasingly limited to the treatment of infertility. While the results of intrauterine insemination seem satisfactory for serodiscordant couples living with HIV, in vitro fertilization results appear to be unfavorable when the woman is infected with HIV. In vitro fertilization results appear to be comparable to those in general population when only the man is infected with HIV. It can be assumed that ovaries are impacted by the treatment and/or the HIV in infected women.

In azoospermic men with congenital bilateral absence of the vas deferens (CBAVD), it is not known whether the outcomes of intracytoplasmic sperm injection (ICSI) depend on the quality of testicular spermatogenesis (as determined histopathologically). We retrospectively studied the impact of spermatogenesis quality on ICSI outcomes in 108 azoospermic men with CBAVD consulting in a university hospital's department of andrology and reproductive biology. As part of an ICSI program, sperm samples were obtained from the epididymis [by microsurgical epididymal sperm aspiration (MESA); n = 47] or the testis [by testicular sperm extraction (TESE); n = 14] or both (MESA + TESE, n = 47). In the TESE group (i.e., TESE-only and MESA + TESE), spermatogenesis was normal in 21 of the 108 men (19.4%) and hypospermatogenesis occurred in 33 (30.5%). The fertilization rate was significantly lower in the hypospermatogenic group than in the normospermatogenesis group (65.6 and 72.9%, respectively; p = 0.02); this was also true for the embryo cleavage rate (88.6 and 92.1%, respectively; p = 0.007), and the proportion of embryos with fewer than 30% of enucleate fragments (79.5 and 86.9%, respectively; p = 0.02). Our study results showed that impaired spermatogenesis had a negative impact on certain early-stage biological outcomes of ICSI. In CBAVD, male factors are likely to exert a harmful effect on the early stages of embryo development.
