Ovulation induction and controlled ovarian stimulation using letrozole gonadotropin combination: A single center retrospective cohort study

Letrozole-low dose gonadotropins combination appears to be effective across different causes of infertility for superovulation. The letrozole-low dose gonadotropin combination resulted in high rate of monofolliculogenesis, low occurrence of multiple gestations and no case of OHSS or cycle cancellation.
