[Induced abortion in France: results of the COCON study].

Objective: The aim of this article is to describe conditions of abortions practices in France.

Materials And Methods: The study was based on the COCON survey. This survey was carried out among a representative sample of 2863 women aged 18 to 44 living in metropolitan France.

Contraception: from accessibility to efficiency.

Background: Despite the widespread use of medical contraception in France, the prevalence of abortion remains stable. A cross-sectional population-based survey was designed to study the characteristics of current contraceptive use in France, the different types of contraceptive failure, and the reasons reported for not using contraception.

Methods: A representative sample of 14 704 French households was randomly selected from the telephone directory.

Influence of ovarian cysts on the results of in vitro fertilization.

Objective: To determine if ovarian cysts are associated with a particular basal endocrine profile and impair follicular growth.

Design: Retrospective study.

Setting: In Vitro Fertilization (IVF) Center.

Paradoxical ovarian stimulations in the use of LHRH analogs.

In the case of in vitro fertilization, LHRH analogs are used to induce an hypophysary blockage, before the phase of stimulation, via administration of exogenous gonadotropin. During in vitro fertilization attempts using LHRH analogs, the blockage is controlled after 14 days of treatment through measurement of the plasmatic estradiol and pelvic ultra-sonography. In this retrospective study, which concerned 1075 in vitro fertilization cycles, a paradoxical ovarian stimulation with LHRH analogs was observed in 93 cases (8.
