Oocyte retrieval versus conversion to intrauterine insemination in patients with poor response to gonadotropin therapy.

摘要

We compared cycle characteristics and outcomes for planned in vitro fertilization cycles with five or fewer developing follicles that proceeded to retrieval (n = 170) with those that converted to intrauterine insemination (IUI) (n = 50). The risk of no embryo transfer was 24% in cycles that proceeded to retrieval. Live birth rate per cycle started was similar for IUI (6%) compared with retrieval (7%).
