Double versus single homologous intrauterine insemination for male factor infertility: a systematic review and meta-analysis.

Male factor infertility affects 30%-50% of infertile couples worldwide, and there is an increasing interest in the optimal management of these patients. In studies comparing double and single intrauterine insemination (IUI), a trend towards higher pregnancy rates in couples with male factor infertility was observed. Therefore, we set out to perform a meta-analysis to examine the superiority of double versus single IUI with the male partner's sperm in couples with male factor infertility.

The progesterone positive feedback effect in women after ovariectomy.

Various ovarian substances regulate the secretion of gonadotrophins during the menstrual cycle, but there are still several unclarified issues. The aim of this study was to investigate the positive feedback effect of progesterone during the immediate period following ovariectomy. Experiments were performed in 12 normally cycling women (aged 39-49 years).

Design: Systematic review and meta-analysis of randomised controlled trials.

Data Sources: Cochrane Central Trials Registry, ISI Web of Science, Medline, and reference lists of relevant studies to July 2010; hand searches in key journals.

Failure of the GnRH antagonist ganirelix to block the positive feedback effect of exogenous estrogen in normal women.

This study investigated whether the GnRH antagonist ganirelix is able to block the positive-feedback effect of E2 in normal women. Ganirelix was unable to block the positive-feedback effect, suggesting that the clinical efficacy of GnRH antagonists in IVF cycles is determined by the hyperstimulation process.
