Inhibitory Effect of Submaximal Doses of Ghrelin on Gonadotropin Secretion in Women
(2014)
The effect of ghrelin on gonadotropin secretion has been equivocal. Recent data have shown an inhibitory effect of repeated injections of ghrelin on nocturnal LH and FSH secretion in women. The aim of this study was to ...
Effect of Ghrelin and Thyrotropin-releasing Hormone on Prolactin Secretion in Normal Women
(2010)
It is known that ghrelin stimulates the secretion of prolactin in women. The aim of this study was to examine the effect of exogenous thyrotropin-releasing hormone (TRH) on ghrelin-induced prolactin release. Ten healthy ...
Inhibin secretion in women with the polycystic ovary syndrome before and after treatment with progesterone
(2011)
Objectives: It has been suggested that inhibin secretion is altered in women with the polycystic ovary syndrome (PCOS). However, the contribution of a preceding luteal phase has not been taken into account. The aim of the ...
Effect of ghrelin and metoclopramide on prolactin secretion in normal women
(2011)
Background: Administration of ghrelin to women stimulates the secretion of PRL but the mechanism is not known. Aim: The aim of the study was to investigate the effect of the dopamine receptor blocker, metoclopramide, on ...
Growth hormone and prolactin response to ghrelin during the normal menstrual cycle
(2009)
Objective It has been suggested that exogenous oestradiol augments ghrelin-induced growth hormone (GH) secretion in postmenopausal women. Whether endogenous oestrogens exert a similar effect during the normal menstrual ...
The progesterone positive feedback effect in women after ovariectomy
(2013)
Various ovarian substances regulate the secretion of gonadotrophins during the menstrual cycle, but there are still several unclarified issues. The aim of this study was to investigate the positive feedback effect of ...
The role of gonadotropins in the follicular phase
(2010)
Folliculogenesis in humans is a lengthy process that involves several regulators. Pituitary gonadotropins play crucial roles in the late stages, particularly in the last 15 days of follicle maturation. During the intercycle ...
Prognostic value of follicular fluid 25-OH vitamin D and glucose levels in the IVF outcome
(2010)
Objectives: The aim of the present study was to measure serum and follicular fluid 25-OH vitamin D and glucose levels in women who underwent IVF-ET treatment and to further investigate whether the circulating 25-OH vitamin ...
Attenuating activity of the ovary on LH response to GnRH during the follicular phase of the cycle
(2014)
Objective Oestradiol sensitizes the pituitary to GnRH, while gonadotrophin surge attenuating factor (GnSAF) may oppose this action. Using the LH response to GnRH during treatment with FSH as an in vivo bioassay for GnSAF, ...
Attenuation of the oestrogen positive feedback mechanism with the age in postmenopausal women
(2015)
ObjectiveIt has been reported that the positive feedback mechanism of oestrogens and progesterone is preserved, although attenuated, in late postmenopausal years. Whether this is also true for the positive feedback effect ...
