Abstract:
Some fertility patients with polycystic ovary syndrome (PCOS) undergoing controlled ovarian hyperstimulation (COH) experience ceased follicular growth during COH and fail to superovulate. In this article, 24 such PCOS patients resumed COH 15-20 days after previous COH treatment was stopped while patients were under ovarian downregulation. Seventeen cases achieved oocyte retrieval, of which 14 underwent embryo transfer and 12 resulted in clinical pregnancy. The remaining seven cases saw ceased follicular growth at 13 mm. This provides a rescue protocol for failed COH patients with PCOS.

Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
