[Alternative approaches to ovarian stimulation].

Ovarian stimulation during GnRH agonists treatment can sometimes result in hyperstimulation with the risk of serious complication. Therefore, other protocols, associating antagonists, have been set out in the search for more effective ovarian stimulation resulting in satisfactory implantation with fewer complications. Still, these protocols need confirmation of their efficiency, which most other series have not reported yet; while a higher rate of unsuccessful egg retrieval and a reduction in the number of satisfactory transfers have been observed in the absence of stimulation. Currently, new molecules and personalized treatments offer a new perspective in ovulation induction with the aim of optimizing results and reducing complications.
