Novel aspects of the endocrinology of the menstrual cycle
(2014)
Ovarian control of gonadotrophin secretion is normally achieved via the feedback mechanisms mediated by oestradiol and progesterone. Evidence has been provided that nonsteroidal substances, such as inhibin A and B, participate ...
Current and future status of ovulation induction in polycystic ovary syndrome
(1997)
Great progress has been achieved during the last 20 years in the field of ovulation induction in patients with polycystic ovary syndrome (PCOS). Clomiphene citrate remains the first line of treatment for all anovulatory ...
Evidence of differential control of FSH and LH responses to GnRH by ovarian steroids in the luteal phase of the cycle
(2002)
BACKGROUND: It is known that during the follicular phase of the cycle, estradiol sensitizes the pituitary to GnRH. The aim of this study was to determine the role of ovarian steroids in the control of GnRH-induced gonadotrophin ...
Changes in pituitary sensitivity to GnRH in estrogen-treated post-menopausal women: evidence that gonadotrophin surge attenuating factor plays a physiological role
(2004)
BACKGROUND: The purpose of this study was to investigate changes in pituitary response to GnRH in post-menopausal women during substitution treatment with exogenous estrogen and progesterone. METHODS: Seven healthy ...
Ovarian feedback, mechanism of action and possible clinical implications
(2006)
The secretion of gonadotrophins from the pituitary in women is under ovarian control via negative and positive feedback mechanisms. Steroidal and non-steroidal substances mediate the ovarian effects on the hypothalamic-pituitary ...
Ovarian regulators of gonadotropin secretion
(2000)
Great progress in the ovarian mechanisms that control gonadotrophin secretion in women has recently been achieved, Estradiol (E-2) is the main component of the ovarian negative effect on basal gonadotropin secretion during ...
