[Use of GnRH analog for induction of gonadotropin ovulatory surge in cycles stimulated by clomiphene citrate and menopausal gonadotropin in an in vitro fertilization program].

In 23 women treated for sterility by the in vitro fertilization method the gonadotropins ovulatory surge was stimulated by applying a GnRH analogue (Buserelin). The authors showed that a single injection of GnRH analogue in the cycles stimulated with clomiphene citrate and menopausal gonadotropin causes pituitary output of both LH and FSH which is sufficient for morphological and functional maturity of the oocytes. After such treatment two patients conceived and delivered healthy babies.
