Qualité de la stimulation en FIV

Quality control in IVF stimulation requires first establishing the ovarian follicle status, then a hormone strategy, and finally monitoring follicle maturation. The ovary examination includes an ultrasound examination to evaluate the number of follicles and their size and hormone tests measuring FSH, E2, but most particularly AMH levels. The hormone strategy during COH mainly seeks to obtain a large number of antral follicles of a homogeneous size and quality, using either FSH suppression at the end of the luteal phase or the administration of a GnRH antagonist in the premenstrual phase. Follicle maturation during COH is usually monitored using ultrasound, with three-dimensional and/or software measurements to evaluate follicle volume.
