Insulin secretion and insulin-like growth factor-I levels in active and controlled acromegaly.

abstract：OBJECTIVE:Pituitary responsiveness to GnRH varies throughout the normal menstrual cycle. We have investigated whether there are differences in the ovarian mechanisms which regulate gonadotrophin secretion between the follicular and the luteal phase of the cycle. DESIGN:Normally ovulating women were studied during the ...
