Clinical use of aromatase inhibitors (AI) in premenopausal women

The sum of data available on the use of AI for inducing ovulation remains however meager to this date and is mainly constituted of pilot and non-randomized trials. Yet mounting evidence tends to support AIs' advantages over CC for induction of ovulation. Hence, we think that the likelihood that these drugs will play a key role in induction of ovulation in the future is high. AIs appear particularly interesting for treating unexplained infertility because AI-FSH/hMG regimens are lighter than FSH-only regimens while retaining the high pregnancy rates of these latter treatments.
