[Analogs of GnRH and fertilization in vitro. Value of the use of GnRH analogs in the stimulation and monitoring of ovulation for fertilization in vitro].

Gn RH analogues seemed to us to be very useful in in-vitro fertilisation. They make it easier to programme oocyte recovery. They avoid an endogenous surge of LH, and they particularly seemed to increase significantly the percentage of pregnancies that continue after embryo transfer.
