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 ... -
Exogenous progesterone for LH surge prevention is redundant in ovarian stimulation protocols
(2021)During ovarian stimulation for IVF–embryo transfer treatment, a premature LH surge may lead to progesterone elevation that disrupts endometrial maturation and affects the probability of pregnancy following fresh embryo ... -
Ghrelin suppresses the GnRH-induced preovulatory gonadotropin surge in dairy heifers
(2016)Ghrelin, a known growth hormone (GH) secretagogue, alters gonadotropin secretion in many species. Our objectives were to study the effects of ghrelin, on GH, LH, FSH secretion, and on luteal function of the ensuing estrous ... -
In early pubertal boys, testosterone and LH are associated with improved anti-oxidation during an aerobic exercise bout
(2019)Purpose: To investigate the association of the hypothalamic-pituitary-testicular (HPT) axis with pro- and anti- oxidation, in relation to puberty and obesity in boys, before and after an aerobic exercise bout. Methods: ... -
Making IVF more effective through the evolution of prediction models: is prognosis the missing piece of the puzzle?
(2018)Assisted reproductive technology has evolved tremendously since the emergence of in vitro fertilization (IVF). In the course of the recent decade, there have been significant efforts in order to minimize multiple gestations, ... -
A study on ghrelin and LH secretion after short fasting and on ghrelin levels at perioestrual period in dairy cattle
(2019)In two experiments, we studied (a) the changes of LH secretion in heifers under different feeding schedules and (b) total ghrelin concentration at oestrus in cows and heifers. In experiment one, synchronized heifers were ... -
A study on stress response and fertility parameters in phenotypically thermotolerant and thermosensitive dairy cows during summer heat stress
(2020)It is well documented that heat stress (HS) causes subfertility in dairy cows. However, during the last ten years we have been observing that, under high temperature–humidity index (THI ≥ 75), despite the overall reduced ... -
Submaximal doses of ghrelin do not inhibit gonadotrophin levels but stimulate prolactin secretion in postmenopausal women
(2017)Objective: An inhibitory effect of ghrelin on gonadotrophin secretion has been reported in normally menstruating women possibly modulated by endogenous oestrogen. The aim of this study was to examine the effect of ghrelin ...
