Chromosomal abnormalities in oocyte donor candidates: a French survey of over 8,200 karyotypes.

Objective: To study karyotypes of >8,200 oocyte donor candidates in nulliparous or multiparous women compared with a reference population.

Design: A retrospective observational multicentric study.

Setting: University Hospital Centers.

Factors associated with decreased ovarian reserve in Crohn's disease: A systematic review and meta-analysis.

Introduction: It is still unclear whether Crohn's disease (CD) might be associated with diminished ovarian reserve (OvR) and factors influencing anti-Mullerian hormone (AMH) levels in CD are poorly known.

Material And Methods: We conducted a comprehensive literature search of multiple electronic databases from inception to June 2022 to identify all studies reporting AMH levels or factors associated with diminished OvR in patients with CD.

Results: Of the 48 studies identified in our search, eight (including 418 patients with CD) were finally included.

Contraception during medical studies: A French study of 2,323 residents.

Objective: The main objective of this work was to establish the contraceptive profile of French female medical residents and to assess the impact of workload on their choice of contraception method as well as difficulties encountered.

Study Design: We conducted a descriptive, cross-sectional, prospective national study over six months, between May and October 2019, using an anonymous online survey sent to all female medical residents in France. We formed two study groups according to reported working hours: W+ and W-.

Effect of Gonadotropin Types and Indications on Homologous Intrauterine Insemination Success: A Study from 1251 Cycles and a Review of the Literature.

Objective: To evaluate the IUI success factors relative to controlled ovarian stimulation (COS) and infertility type, this retrospective cohort study included 1251 couples undergoing homologous IUI.

Results: We achieved 13% clinical pregnancies and 11% live births. COS and infertility type do not have significant effect on IUI clinical outcomes with unstable intervention of various couples' parameters, including the female age, the IUI attempt rank, and the sperm quality.

Comparative prospective study of 2 ovarian stimulation protocols in poor responders: effect on implantation rate and ongoing pregnancy.

Background: In patients treated with IVF, the incidence of poor ovarian response (POR) after ovarian stimulation varies from 9 to 25 %. However, at present, there are no clear guidelines for treating these poor responders. This study was designed to compare two different ovarian stimulation protocols and addresses future perspectives in the management of these unfortunate patients.

Sperm cryopreservation in adolescents and young adults with cancer: results of the French national sperm banking network (CECOS).

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.

[Declining fertility with age].

The will to be a mother at a late age has become a real problem of society for many reasons, first and foremost because of efficient birth control, long studies and second matrimonies. In front of these still young women but quite "old" for maternity, practitioners specialized in medically assisted procreation (MAP) are often helpless, specially because most of the patients think that the MAP will be able to cure the natural decline of fertility. However, MAP's procedures cannot correct the decrease of pregnancies' rates and the increase of spontaneous miscarriages linked with the age.
