IVF practice is increasing for women aged over fourty, in France. Analysis shows that when women's age increases, stimulation protocols with GnRH analogues using a short blocking period or "classical" protocols (without GnRH) are more and more used. However, the highest pregnancy 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 difference between these protocols and those using hMG.
在法国，40岁以上女性的体外受精（IVF）治疗正在增加。分析表明，随着女性年龄的增长，越来越多地使用促性腺激素释放激素（GnRH）类似物的短期阻断方案或“经典”方案（不使用GnRH）。然而，使用GnRH类似物的长期阻断方案仍能获得最高的妊娠率。使用纯促卵泡生成素（FSH）的刺激方案的比例也在增加，但这些方案与使用人绝经期促性腺激素（hMG）的方案之间的妊娠率没有差异。
