Mild stimulation in in vitro fertilization.
Current approaches to ovarian stimulation for in vitro fertilization (IVF) are aimed at optimizing the number of oocytes retrieved in a treatment cycle. This approach is not without risks. Moreover, as the true costs of multiple pregnancy become clearer, the need to produce multiple embryos for transfer is increasingly questioned. Increasing knowledge of the physiological mechanisms involved in follicular development and dominance has led to new strategies in ovarian stimulation for IVF. The clinical availability of GnRH antagonists allows the normal cycle to be harnessed and manipulated by mild interventions to produce sufficient oocytes for successful IVF treatment. Recent evidence suggests that oocyte quality after mild stimulation may be superior to that after conventional stimulation regimens.
