Background: The objective of this study is to evaluate the progesterone level (P Level) on the day of HCG triggering in GnRh agonist and antagonist protocols, and its correlation with clinical pregnancy rate and miscarriage rate. Premature luteinization during in vitro fertilization (IVF) was commonly happened before the introduction of GnRh analogues. High level of unwanted progesterone that i...

Background The optimal stimulation protocol for poor responder patients is a therapeutic challenge. GnRH antagonist protocol has been proposed as a potentially proper option for poor responders. Nevertheless, there is no significant difference in terms of clinical pregnancy and cancellation rates be tween the GnRH antagonist and agonist cycles. Therefore, this subset of patients might be the be...

background: our objective was to evaluate the effectiveness of clomiphene citrate (cc) vs. letrozole (l) plus human menopausal gonadotropin (hmg) in gonadotropin releasing hormone (gnrh) antagonist protocol in poor prognosis women with previous failed ovarian stimulation undergoing intracytoplasmic sperm injection (icsi). materials and methods: this retrospective cohort study included cycles wi...

Background: This study aims to verify if luteal estradiol pre-treatment improves IVF/ICSI outcomes in a GnRH antagonist protocol as compared to a micro dose GnRH agonist protocol in poor-responding patients. Materials and Methods: A total of 116 IVF/ICSI cycles were included in this prospective randomized clinical trial. The selected women were randomly assigned to receive an estradiol pre-trea...

•We used Random-Start for the IVF cycle in urgent settings of gynecological cancer.•Oocytes can be obtained at any time before cancer treatment efficiently.•Oocyte maturity rates were comparable with conventional antagonist protocol.•Random-Start protocol is promising in emergency fertility preservation.

background: microdose flare-up gnrh agonist and gnrh antagonist have become more popular in the management of poor ovarian responders (por) in recent years; however, the optimal protocol for por patients undergoing in vitro fertilization has still been a challenge. methods: in this observational study design, two hundred forty four poor ovarian responders were retrospectively evaluated for thei...

The goal of ovarian Stimulation for assisted reproductive technologies (ART) is obtaining multifollicular growth ovarian hyper stimulation syndrome (OHSS) is one of the most Severe and also potentially Life-threatening complications, which happens in 1-10% of IVF cycles. The most common risk factors which are related to OHSS are polycystic ovarian syndrome (PCOS), younger age, high preovulatory...

Background Our objective was to evaluate the effectiveness of clomiphene citrate (CC) vs. letrozole (L) plus human menopausal gonadotropin (hMG) in gonadotropin releasing hormone (GnRH) antagonist protocol in poor prognosis women with previous failed ovarian stimulation undergoing intracytoplasmic sperm injection (ICSI).
