Aromatase inhibitors for ovulation induction.

Normogonadotropic anovulation, including polycystic ovary syndrome (PCOS), is one of the main causes of infertility. Recent meta-analysis and randomized controlled trial suggest the use of aromatase inhibitors (ie, letrozole) as effective drug and first-line treatment to restore fertility in these patients. The current manuscript will give a critical, provocative, and personal point of view on the topic.
