Changes in pituitary response to gonadotropin releasing hormone following bilateral ovariectomy in women treated with follicle-stimulating hormone
(1996)Superovulation induction in women attenuates the pituitary response to gonadotropin-releasing hormone (GnRH). The aim of this study was to assess the duration of the suppressing activity of the ovaries on the pituitary. ... -
Comparison of aspiration and hormonal therapy for the treatment of ovarian cysts in cows
(2009)Despite the variety of hormonal treating regimes used, a proportion of cows with cystic ovarian disease (COD) fail to be cured. The hypothesis of this study was that cyst aspiration would improve the curing rate and/or ... -
Corifollitropin alfa compared with follitropin beta in GnRH-antagonist ovarian stimulation protocols in an unselected population undergoing IVF/ICSI
(2017)Recombinant DNA technologies have produced Corifollitropin alfa (CFa) used during IVF/ICSI in order to keep the circulating FSH levels above the threshold necessary to support multi-follicular growth for a week. In this ... -
Drug-induced endocrinopathies and diabetes: A combo-endocrinology overview
(2019)In the currently overwhelming era of polypharmacy, the balance of the dynamic and delicate endocrine system can easily be disturbed by interfering pharmaceutical agents like medications. Drugs can cause endocrine abnormalities ... -
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 ... -
The endocrine effects of multiple folliculogenesis
(2011)Induction of multiple follicular development is a common practice in IVF programmes. Nevertheless, such an approach is not without implications. Apart from the high multiple pregnancy rate, marked changes in the secretion ... -
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 ... -
Factors affecting outcome after ICSI with spermatozoa retrieved from cryopreserved testicular tissue in non-obstructive azoospermia
(2005)There is a lack of data regarding variables affecting the treatment outcome for non-obsructive azoospermia when spermatozoa from cryopreserved testicular specimens are utilized for ICSI. The objective of the present ... -
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 ... -
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 ... -
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, ... -
Purification of a candidate gonadotrophin surge attenuating factor from human follicular fluid
(1999)Gonadotrophin surge attenuating factor (GnSAF) is a new non-steroidal ovarian substance, different from inhibin, which attenuates the pre-ovulatory luteinizing hormone (LH) surge in superovulated women. Human follicular ... -
Reporting on the Role of miRNAs and Affected Pathways on the Molecular Backbone of Ovarian Insufficiency: A Systematic Review and Critical Analysis Mapping of Future Research
(2021)Ovarian insufficiency is identified as a perplexing entity in the long list of pathologies impairing fertility dynamics. The three distinct classifications of ovarian insufficiency are poor ovarian response, premature ... -
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 ... -
Transdermal testosterone pretreatment in poor responders undergoing ICSI: A randomized clinical trial
(2016)STUDY QUESTION: Does pretreatment with transdermal testosterone increase the number of cumulus-oocyte complexes (COCs) retrieved by more than 1.5 in poor responders undergoing intracytoplasmic sperm injection (ICSI), using ...
