[In vitro fertilization (IVF): why doing it in stimulated cycles?]

Assisted reproductive technology is a difficult course for the couples. Our purpose is to be effective without damaging the patient and the child to be born. The cumulative rates of success are strictly dependent on the number of oocytes and on the obtained top quality embryos and thus on the realization of an effective stimulation. The risk of multiple pregnancies can be adjusted by an adapted policy of transfer. The transfer of a fresh embryo followed by cycles of frozen embryos transfers gives very satisfactory cumulative pregnancy rates.
