OBJECTIVE To assess the relationship between the estrogen-progesterone alterations before and after ovulation trigger and treatment success in intrauterine insemination (IUI) cycles. MATERIALS AND METHODS Two hundred fifty-one women with infertility underwent ovulation induction
Phase III trial comparing the efficacy and safety of recombinant‐ or urine‐derived human chorionic gonadotropin for ovulation triggering in Japanese women diagnosed with anovulation or oligo‐ovulation and undergoing ovulation induction with follitropin‐alfa
Aim Outside of Japan, recombinant-human chorionic gonadotropin (r-hCG) is widely used for the induction of final follicular maturation and early luteinization in women undergoing ovulation induction; whereas in Japan, urine-derived hCG (u-hCG) is predominantly used. The primary o
The use of gonadotropin-releasing hormone antagonist post-ovulation trigger in ovarian hyperstimulation syndrome
The purpose of this paper is to assimilate all data pertaining to the use of gonadotropin-releasing hormone (GnRH) antagonists in in vitro fertilization cycles after ovulation trigger to reduce the symptoms of ovarian hyperstimulation syndrome (OHSS). A systematic review of the l
GnRH agonist ovulation trigger and hCG-based, progesterone-free luteal support: a proof of concept study.
BACKGROUND It is now well established that a GnRH agonist (GnRHa) ovulation trigger completely prevents ovarian hyperstimulation syndrome. However, early studies, using conventional luteal support, showed inferior clinical results following a GnRHa trigger compared with a convent
Serum Anti-Müllerian Hormone and Inhibin B Levels at Ovulation Triggering Day Can Predict the Number of Immature Oocytes Retrieved in In Vitro Fertilization Cycles
The aim of this study was to investigate whether serum levels of anti-Müllerian hormone (AMH) and inhibin B at ovulation triggering day correlate with the number of immature oocytes obtained from stimulated in vitro fertilization (IVF) cycles. Fifty-nine consecutive cycles of ova
Identification of new ovulation-related genes in humans by comparing the transcriptome of granulosa cells before and after ovulation triggering in the same controlled ovarian stimulation cycle.
STUDY QUESTION Which genes and molecular mechanisms are involved in the human ovulatory cascade and final oocyte maturation? SUMMARY ANSWER Up-regulated genes in granulosa cells (GC) represented inflammation, angiogenesis, extracellular matrix, growth factors and genes previously
Ovulation triggering with GnRH agonists
Ovarian hyperstimulation syndrome (OHSS) remains a major complication of IVF. Triggering ovulation with human chorionic gonadotrophin (HCG) (as a surrogate to LH) is a major factor in the initiation of OHSS. The pathological process usually intensifies if pregnancy is achieved, a
Comparing the effect of gonadotropin-releasing hormone agonist and human chorionic gonadotropin on final oocytes for ovulation triggering among infertile women undergoing intrauterine insemination: An RCT
Background The purpose of triggering in ovulation induction is to induce the final maturation of oocytes and their release from the ovary for fertilization. Objective The aim of the present study was to compare the effectiveness of gonadotropin-releasing hormone (GnRH) agonist an
Multivariate analysis identifies the estradiol level at ovulation triggering as an independent predictor of the first trimester pregnancy-associated plasma protein-A level in IVF/ICSI pregnancies.
STUDY QUESTION Can independent predictors of pregnancy-associated plasma protein-A (PAPP-A) levels be identified in a group of women who conceived following IVF/ICSI? SUMMARY ANSWER The significantly decreased PAPP-A level in IVF and ICSI pregnancies compared with non-IVF/ICSI pr
I-27: GnRH Agonist Triggering and Luteal Phase Support
Background GnRH agonist triggering is one of the strategies for ovulation triggering and final maturation of oocytes. So , should be notice for luteal phase support in these cycles. At the first it was began for prevention of severe OHSS but it was associated with luteal phase pr
