Gonadotrophin ovulation induction and enhancement outcomes: analysis of more than 1400 cycles.

Ovulation induction (OI) or ovulation enhancement (OE) with gonadotrophins can be a reasonable treatment option for patients with a variety of infertility diagnoses. It must be used with extensive monitoring and management given the risk of multiple pregnancy,especially high-order multiples. This retrospective study evaluated per cycle outcomes of a large cohort of 1452 gonadotrophin OI/OE cycles at an academic infertility centre, and the efficacy of specific guidelines in limiting multiple pregnancy.

The impact of a gonadotropin-releasing hormone antagonist on gonadotropin ovulation induction cycles in women with polycystic ovary syndrome: a prospective randomized study.

Objective: To evaluate the effect of the gonadotropin-releasing hormone antagonist Ganirelix on gonadotropin ovulation induction (OI) in patients with polycystic ovary syndrome (PCOS).

Design: Prospective, randomized, controlled study.

Setting: Academic infertility center.

Objective: To evaluate the impact on the rates of clinical pregnancy and live birth of polyploidy after intracytoplasmic sperm injection (ICSI).

Design: Retrospective cohort study.

Setting: University-based IVF center.
