BACKGROUND Premature luteinization during in vitro fertilization was commonly happened before the introduction of GnRh analogues. High level of unwanted progesterone is associated with adverse pregnancy outcome and is thought to be induced by inappropriate LH elevation. OBJECTIVE To evaluate the progesterone level on the day of Human Chorionic Gonadotropin (HCG) triggering in GnRh agonist and...
In this paper, a retrospective cohort study was conducted to the high ovarian responders in GnRH-antagonist protocols of IVF/ICSI cycles. The purpose of the study is to investigate whether dual triggering of final oocyte maturation with a combination of gonadotropin-releasing hormone (GnRH) agonist and human chorionic gonadotropin (HCG) can improve the clinical outcome compared with traditional...
OBJECTIVES To compare the live birth rates and moderate/severe ovarian hyperstimulation syndrome (OHSS) rates of 2 different approaches using gonadotropin-releasing hormone (GnRH) agonist triggering in high responder women. Methods: A retrospective cohort study was performed to evaluate intracytoplasmic sperm injection (ICSI) and embryo transfer (ET) outcomes in high responder women who underwe...
Westergaard LG, Yding Andersen C. GnRH agonist (Buserelin) or hCG for ovulation induction in GnRH antagonist IVF/ICSI cycles: a prospective randomised study. Hum Reprod 2005; 20:1213–1220. Humaidan P, Bungum L, Bungum M, Yding Andersen C. Rescue of corpus luteum function with peri-ovulatory hCG supplementation in IVF/ICSI GnRH antagonist cycles in which ovulation was triggered with a GnRH agoni...
OBJECTIVE This study aims to evaluate the effectiveness of GnRH agonist in comparison with hCG for triggering final oocyte maturation in endometrial preparation of letrozole stimulation protocols for frozen-thawed embryo transfer. METHODS The frozen-thawed embryo transfer cycles (FET) that use the letrozole stimulation protocols for endometrial preparation were divided into two groups accordi...
Previous results from this laboratory suggested that the same active conformation of the lutropin/choriogonadotropin receptor (LHR) is involved in the stimulation of G proteins and in triggering the internalization of the bound agonist. We have now analyzed two naturally occurring, constitutively active mutants of the human LHR. These mutations were introduced into the rat LHR (rLHR) and are de...
routinely, a bolus of 5.000-10.000 iu human chorionic gonadotropin (hcg) is usedfor the final follicular maturation and ovulation as a standard method. hcg has thesame effect of luteinizing hormone (lh) with long half-life. it has the longlutheotrophic effect which increases the risk of ovarian hyper stimulation syndrome(ohss). recently, gonadotropin-releasing hormone agonist (gnrh-a) trigger h...
With the increasing use of gonadotropin releasing hormone antagonist protocols, it has become an option to trigger ovulation with gonadotropin releasing hormone agonist which has several advantages over human chorionic gonadotropin triggering; among those an elimination or reduction in ovarian hyperstimulation syndrome, and a reduction in luteal phase discomfort. Thus, this paper questions the ...
