The effect of a GnRH antagonist on follicle maturation in normal women
(2019)Research question: Ganirelix is a gonadotrophin-releasing hormone (GnRH) antagonist used for the prevention of premature LH surge during ovarian stimulation. What is the impact of ganirelix on follicle maturation in normal ... -
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 ... -
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 ... -
Gonadotropin Surge-Attenuating Factor: A Nonsteroidal Ovarian Hormone Controlling GnRH-Induced LH Secretion in the Normal Menstrual Cycle
(2018)Gonadotropin surge-attenuating factor (GnSAF) is a nonsteroidal ovarian substance, which attenuates the endogenous LH surge in superovulated women. Different molecular sequences have been found, but only one of them has ... -
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 ... -
Leptin in human reproduction
(1999)The recent discovery of the obese (ob) gene has provided new insight into the mechanism which controls body fat mass. Leptin, a product of the ob gene, serves as the link between fat and the brain. This protein, by acting ... -
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 tissue cryopreservation and transplantation to delay menopause: facts and fiction
(2020)Ovarian tissue cryopreservation and transplantation (OTCT) is increasingly being used in young cancer patients for fertility restoration and prevention of premature ovarian insufficiency (POI) and has recently been advocated ... -
Stress, female reproduction and pregnancy
(2019)Stress is one of the commonest and underappreciated causes of reproductive frailty in women. The stress system leads to adaptive responses via mobilization of hormonal systems. Adaptability and resistance to stress are ... -
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. ... -
Two cases of bovine holoacardius amorphus monsters [Μελέτη δυο περιπτώσεων ακάρδιων άμορφων (Holocardius Amorphous totalis) τεράτων οε βοοειδή]
(2017)Two rare cases of holoacardius amorphus totalis monsters are reported herewith. The monsters were examinedmacroscopically, radiographically and histologically, whereaskaryotyping was performed in one normal twin. Both ...
