Absence of leptin expression and secretion by human luteinized granulosa cells
(2003)Whether leptin is secreted by the human ovary is not known. The available data on leptin gene (ob gene) expression by human granulosa cells are conflicting. The aim of the present study was first to re-examine the expression ... -
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 ... -
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 ... -
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 ... -
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 ... -
Oxytocin is not important for the control of gonadotrophin secretion in the late follicular phase of the cycle
(2007)Objective To study the role of oxytocin in basal and GnRH-induced gonadotrophin secretion in normal women. Design Normal women were studied in three cycles. When the diameter of the leading follicle was 15-16 mm, the women ...
