IVF IN WOMEN OVER THE AGE OF 40

IVF practice is increasing for women aged over fourty, in France. Anal ysis shows that when women's age increases, stimulation protocols with GnRH analogues using a short blocking period or << classical >> proto cols (without GnRH) are more and more used. However the highest pregna ncy rates are still obtained for protocols using GnRH analogues with a long blocking period. The proportion of the stimulation regimen using pure FSH is also increasing, but pregnancy rates do not show any diff erence between these protocoles and those using hMG.
