[Induction of ovulation by pulsatile gonadoliberin administration. Indications and limits].
With its simplicity, innocuity and efficacy, pulsatile GnRH administration constitutes a considerable advance in ovulation induction techniques. Its purpose is not to replace classic methods like Clomiphene Citrate, gonadotropins or dopaminergic agonists, but to complement them. While the choice of administration route, IV vs SC is still controversial, the efficacy depends mainly on the selection of the patients susceptible of benefiting from this therapy. Low gonadotropic activity hypothalamic amenorrhea remains the best indication for pulsatile GnRH, as substantiated by the results published over the last 10 years. The other anovulation causes, including PCO-S, are more disputable indications, and prospective studies involving homogeneous populations are necessary to assess the true standing of GnRH in such indications.
