Endometrial Receptivity After GnRH Agonist Triggering

Ovarian Hyperstimulation Syndrome

Conventional luteal phase support after human chorionic gonadotrophin (hCG) triggering in women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) provides adequate pregnancy rates and live birth rates, but Ovarian hyperstimulation syndrome (OHSS) still occurs in 1-3% of the patients. If gonadotropin-releasing hormone agonist (GnRHa) are used instead of hCG, OHSS does not occur, but clinical results are somehow diminished. By testing different luteal support protocols on women undergoing GnRHa triggering, the investigators aim to find out which protocol resembles the most the gene expression profile observed after hCG triggering and conventional luteal phase support, in order to choose it as the most adequate in terms of endometrium receptivity and safety (OHSS incidence).

Short Versus Long Protocol for IVF and IVF+ICSI

InfertilityOvarian Hyperstimulation Syndrome2 more

Purpose: Comparing a GnRH agonist and an antagonist protocol for IVF/ICSI with regard to frequency of ovarian hyperstimulation syndrome (OHSS) (1. outcome measure) quality of life (2. outcome measure) live birth rate (2. outcome measure) gene expression profiles of granulosa and cumulus cells, and concentrations of estradiol and vascular endothelial growth factor in follicular fluid(not only compared between GnRH agonist and antagonist protocol, but also between patients with OHSS and no OHSS and patients becoming pregnant and not becoming pregnant (2. outcome measure), and number of oocytes removed per treatment, number of embryo transfers per treatment and number of spontaneous abortions per treatment (these three parameters are tertiary outcome measures). In addition to the above mentioned efficacy outcome measures the safety outcome measure "frequency of known side-effects" will be compared between the two protocols.

Ovarian Hyperstimulation Syndrome in Patients Triggered by GnRH Agonist for Excessive Follicular...

Ovarian Hyperstimulation SyndromeHypercoagulability

In the literature, the risk of moderate to severe OHSS is 3 to 6% and reaches 31% in high risk populations 9 days after oocyte triggering with hCG. Many studies report no or a markedly decreased risk of OHSS after triggering ovulation with a GnRH agonist. However, criteria to define OHSS are rarely explained and OHSS itself is not thoroughly asserted. It is well known that OHSS is associated with hypercoagulability. However, no study after triggering with a GnRH agonist assessed haemostasis in these high-risk patients with high circulating estradiol levels. Study design, size, duration: In a French academic reproductive medicine centre, a systematic prospective observational follow-up of all patients triggered by GnRH agonist for excessive follicular response will be conducted. Participants/materials, setting, methods: All patients undergoing antagonist protocol and at high risk of OHSS (estradiol level ≥ 3000 pg/mL and/or more than 20 follicles ≥ 11mm on the day of triggering) will be triggered by GnRH agonist. No luteal phase support and a "freeze-all" strategy will be performed. On the day of oocyte retrieval (T0), at 48h (T1) and at day 7 (T2), OHSS and hypercoagulability will be systematically assessed. Haemostasis data will be compared to the initial status of each patient.

Gene Expression Profile After Gonadotropin Releasing Hormone (GnRH) Agonist Trigger of Oocyte Maturation...

Endometrial ReceptivityOvarian Hyperstimulation Syndrome

The purpose of this study is to compare gene expression profiles in endometrial biopsies during the window of implantation after triggers of oocyte maturation using GnRH agonist or hCG and compared with their natural cycles in order to identify genes that may be dysregulated in GnRH agonist-triggered cycles. The investigators also intend to evaluate patients feeling of well being and physical quality of life after GnRH agonist trigger compared with hCG trigger.

Ovarian Hyperstimulation Syndrome

Assess the tolerability of quinagolide 200 μg/day in a dose-titration regimen in oocyte donors undergoing controlled ovarian hyperstimulation and at risk of developing OHSS Secondary Objectives Estimate the effects of a quinagolide dose-titration regimen compared to placebo in peritoneal fluid accumulation, incidence of ascites, OHSS symptoms and clinical laboratory parameters of haemoconcentration

In Vitro Maturation of Immature Oocytes

Polycystic Ovary SyndromeOvarian Hyperstimulation Syndrome

The aim of this study is to aspirate immature oocytes from antral follicles and mature the oocytes in vitro. These mature oocytes will serve for fertilization and the creation of embryos which will be replace in the uterus as performed during normal IVF.We will record the efficacy and safety of this procedure.

Ovarian Hyperstimulation Syndrome

This a prospective randomized double blind study involving patients at high risk of OHSS development with peak serum E2 levels < 4,000 pg/ml comparing the ongoing pregnancy rates in patients who receive adjuvant hCG 1,000 IU at the time of GnRH agonist trigger or adjuvant hCG 1,500 IU 35 hours after GnRH agonist trigger.

Can GnRH Agonist Trigger Prevent Ovarian Hyperstimulation Syndrome?

Ovarian Hyperstimulation Syndrome

Ovarian hyperstimulation syndrome (OHSS) is a major complication of ovarian stimulation for IVF if hCG is used to trigger final oocyte maturation. The investigators propose that using GnRH agonist as a trigger will eliminate OHSS, even in high-risk patients.

Preventive Application of Letrozole Decrease Incidence of Early Onset of OHSS

Ovarian Hyperstimulation Syndrome

Letrozole is one kind of aromatase inhibitors which may have effect on decrease estrogen in luteal phase and inhibit the luteal function of ovary. In 2009, Letrozole was reported as one candidate for the treatment or prevention of ovarian hyperstimulation syndrome.
