Introduction: Endometriosis is a common inflammatory disease and a major cause of infertility through various mechanisms. Materials and method: We conducted a retrospective study in infertile women with endometriosis who underwent in vitro fertilization (IVF) in order to evaluate the particularities and outcome of ovarian stimulation. Results: A total of 59 patients aged 24-40 years were included. Clinical characteristics of the studied group revealed dysmenorrhea in 66.66% of cases, previous ovarian surgery in 57...

OBJECTIVE: Many studies in the literature have found an association between geographic origin and poorer IVF outcomes in African American and Asian minority populations compared with Caucasian populations. The limitations of these studies are multiple (inconsistencies in the characterization of ethnic groups, mostly multicenter studies with large variability in success rates between centers, minorities having more limited and delayed access to care). Thus, socioeconomic status may have been an important bias in judging environmental or "genetic" factors...

OBJECTIVE:  It is known that the single embryo transfer (SET) is the best choice to reduce multiples and associated risks. The practice of cryopreserving all embryos for posterior transfer has been increasingly performed for in vitro fertilization (IVF) patients at the risk of ovarian hyperstimulation syndrome or preimplantation genetic testing for aneuploidy. However, its widespread practice is still controverse. The aim of this study was to evaluate how effective is the transfer of two sequential SET procedures compared with a double embryo transfer (DET) in freeze-only cycles...

OBJECTIVE:  To evaluate whether there is an effect of the physician who transfers the embryos on pregnancy rates in in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) treatment. METHODS:  A total of 757 participants were analyzed between 2012 and 2017. Participants were classified according to 3 physicians who transferred the embryos: ([group 1 = 164 patients]; [group 2 = 233 patients]; [group 3 = 360 patients]). Baseline parameters and IVF-ICSI outcomes were compared between the groups...

BACKGROUND: Growth hormone (GH) is known to be involved in ovarian folliculogenesis and oocyte maturation. In patients with poor ovarian response without growth hormone deficiency (GHD), adjuvant GH treatment improves in-vitro fertilization (IVF) results. Improvement of oocyte quality in IVF by GH replacement was reported in only a few patients with GHD. We report on a new case with study of follicular fluid. METHODS: A 29-year-old patient with hypopituitarism was referred to our infertility center...

OBJECTIVES: For 15 to 30% of infertile couples, no etiology can be found, leading to the diagnosis of "unexplained infertility". The aim of our study was to identify prognostic factors for live birth following in vitro fertilization (IVF) for these couples. METHODS: A retrospective, monocentric study on a cohort of couples undergoing IVF for unexplained infertility with the woman aged ≤ 40 years old. Primary analysis compared couples with a live birth following IVF versus childless couples following IVF...

Chinese sturgeon (Acipenser sinensis) with an evolutionary history of over 200 million years, has a long lifespan, and an extremely late and asynchronous sexual maturation (8-18 years for males and 14-26 years for females), resulting in the difficulty of mature adult culture. However, little is known about the regulatory mechanisms of the transition among ovarian maturation stages in the Chinese sturgeon. We performed de novo transcriptome sequencing of the Chinese sturgeon at different ovarian maturation stages (FII, FIII, and FIV)...

OBJECTIVES: The aim of this study was to evaluate the impact of initial androgenic statute of women with polycystic ovary syndrome (SOPK) on the expected results of in vitro fertilization (FIV). MATERIALS AND METHODS: It is about an exploratory study carried out in 61 unfertile SOPK patients, having profited all from a cycle of FIV/ICSI (intracytoplasmic sperm injection). We have divided our population in two groups according to their hormonal androgenic statute: groups with hyperandrogenism and without hyperandrogenism...
