IVF: classic ovarian stimulation
For many years, a long IVF protocol was used to stimulate ovulation (protocol with GnRH agonists). This approach was spread out over several weeks and an average of 10 to 12 eggs were retrieved per treatment cycle. This procedure was complex. To simplify it, gentler versions of ovarian stimulation were developed. Since its founding, Fertilys has therefore preferred to use short, simpler protocols that are less harsh for the patient, thanks to the use of GnRH antagonists. Ovarian stimulation only takes about 10 days now.
