From menarche to regular menstruation - Endocrinological background
(2006)
Marked changes in hormone secretion occur from childhood to adulthood. Prior to puberty gonadotropin-releasing hormone (GnRH) secretion is markedly suppressed. At the onset of puberty, the hypothalamic gonadostat is ...
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 ...
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 ...
In vitro effects of endothelin-1 on the contractility of myometrium obtained from pre- and postmenopausal women
(2001)
This study was conducted to evaluate the responsiveness of human nonpregnant myometrium to endothelin 1 (ET1) (10(-10) M-10(-6) M) and KCl (80 mM) in relation to the hormonal profile of the women, who were allocated into ...
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 ...
FSH and LH responses to GnRH after ovariectomy in postmenopausal women
(2004)
OBJECTIVE Whether the postmenopausal ovary is still playing a role in the control of gonadotrophin secretion in response to GnRH has not been investigated. The aim of the present study was to test this hypothesis by examining ...
Elimination Half-Life of Anti-Mullerian Hormone
(2012)
Context: Anti-Mullerian hormone (AMH) is a glycoprotein that is secreted by the granulosa cells in the human ovary. In the postpubertal female, circulating AMH reflects the number of follicles within the ovary. It is ...
