First-line IVF outperforms IUI for unexplained infertility in trial

A randomized, multicenter trial compared intrauterine insemination (IUI) with ovarian stimulation to in vitro fertilization (IVF) as first-line treatment in couples with unexplained infertility. The trial reported a cumulative live-birth rate of 31% with IUI versus 55% with IVF after stage 1, finding IUI was not noninferior to IVF; after allowing couples to proceed to further IVF cycles in stage 2, cumulative live-birth rates became similar (70% vs 71%). Serious adverse events, mostly related to oocyte retrieval or hyperstimulation, occurred in 6 couples in the IUI group and 14 in the IVF group.
