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.

Is in vitro maturation of oocytes retrieved ex vivo from ovarian tissue an effective fertility preservation technique in the presence of organic ovarian cysts?

Objective(s): In vitro maturation (IVM) of oocytes retrieved ex vivo from ovarian tissue (OTO-IVM) could be an additional source of mature oocytes with the potential to optimise medical fertility preservation (FP) after oophorectomy. It is often undertaken at the same time as the ovarian tissue cryopreservation (OTC). In the presence of an organic ovarian cyst, OTO-IVM could prove to be the only technique available to permit FP since ovarian stimulation, transvaginal ovarian needle puncture or future ovarian tissue graft are contraindicated.

Fertility of women with cystic fibrosis: a French survey.

Research Question: Although the impact of cystic fibrosis on male fertility is well known, very few studies have investigated its effect on female fertility. This study aimed to evaluate the fertility status of women with cystic fibrosis.

Design: A questionnaire was sent to 220 women with cystic fibrosis.
