Fertility in women is regulated by a series of highly coordinatedand synchronized interactions in the hypothalamicpituitaryovarianaxis (Figure 1A). The central regulator of the axis is the groupof neurons that secrete gonadotropin-releasing hormone (GnRH).1Their cell bodies reside in the arcuate nucleus, and their exonsterminate in the median eminence near the hypothalamicpituitaryportal vasculature. These neurons are unique in that they havean intrinsic firing frequency such that GnRH is secreted inpulses at 60-to-90-minute intervals into the portal vasculatureto be conveyed to the anterior pituitary gland. There GnRH bindsto specific cell-surface receptors . . . [Full Text of this Article]
