title: In vitro fertilization in unstimulated cycles: a new application.
abstract: After four unsuccessful attempts at multiple follicular induction with exogenous gonadotropins, a patient underwent two attempts at IVF in spontaneous cycles triggered with hCG. The second attempt resulted in the transfer of three embryos and a successful singleton intrauterine pregnancy. We believe that unstimulated IVF is a viable option for patients with ovulatory cycles. It should be considered in cases of failed hyperstimulation, and may become a primary treatment option in the future.
