The use of GnRH analogues in combination with exogenous gonadotropins in infertile women.

GnRH analogues suppress LH fluctuations and produce a condition of hypogonadotropic hypogonadism. This action combined with treatment with human menopausal gonadotropins (hMG) has been exploited in programmes of induction of follicular growth in infertile women for both in vivo and in vitro fertilisation. There is improved clinical control over the process of ovulation and the phenomenon of premature luteinization in women with polycystic ovary disease has been eliminated.
