Treatment of normal women with oestradiol plus progesterone prevents the decrease of leptin concentrations induced by ovariectomy
(2000)
To study the role of oestradiol and progesterone in the secretion of leptin, 21 normally ovulating women were recruited from those scheduled for ovariectomy plus hysterectomy performed in mid-follicular phase of the cycle. ...
Leptin concentrations in the follicular phase of spontaneous cycles and cycles superovulated with follicle stimulating hormone
(1998)
It has been reported that oestradiol may play a role in the production of leptin from adipocytes, To investigate this relationship further, nine normally ovulating women were studied during two menstrual cycles, i.e. an ...
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 ...
Luteinizing hormone response to gonadotrophin-releasing hormone in normal women undergoing ovulation induction with urinary or recombinant follicle stimulating hormone
(1998)
Oestradiol enhances pituitary sensitivity to gonadotrophin-releasing hormone (GnRH) in normal women, while in women undergoing ovulation induction the putative factor gonadotrophin surge attenuating factor (GnSAF) attenuates ...
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 ...
Alternate day and daily administration of GnRH antagonist may prevent premature luteinization to a similar extent during FSH treatment
(2005)
BACKGROUND: This randomized controlled trial was designed to evaluate whether a GnRH antagonist given every other day could prevent premature luteinization in women undergoing IVF/ICSI treatment. METHODS: A total of 73 ...
