Oestradiol plus progesterone treatment increases serum leptin concentrations in normal women
(2001)
BACKGROUND: Previous studies have alluded to a role for both oestradiol and progesterone in the secretion of leptin from fat cells in the human, although direct evidence has yet to be obtained. The study aim was to assess ...
Modulating effect of leptin on basal and follicle stimulating hormone stimulated steroidogenesis in cultured human lutein granulosa cells
(2009)
Background: In vitro data have shown conflicting results in terms of the effect of leptin on granulosa cells steroidogenesis. Aim: The aim of the present study was to investigate the effect of low and high doses of leptin ...
Growth hormone, insulin-like growth factor I, and leptin interaction in human cultured lutein granulosa cells steroidogenesis
(2008)
Objective: To investigate the effect of leptin on the actions of growth hormone (GH) and insulin-like growth factor-I (IGF-I) in ovarian steroidogenesis in vitro. Design: In vitro cell culture study. Setting: Research ...
Leptin concentrations in normal women following bilateral ovariectomy
(1999)
To study the relationships between gonadal steroids and leptin, 20 women with normal cycles were investigated during the postoperative period following a laparotomy. Fourteen women underwent bilateral ovariectomy plus total ...
Changes in pituitary response to gonadotropin releasing hormone following bilateral ovariectomy in women treated with follicle-stimulating hormone
(1996)
Superovulation induction in women attenuates the pituitary response to gonadotropin-releasing hormone (GnRH). The aim of this study was to assess the duration of the suppressing activity of the ovaries on the pituitary. ...
