BACKGROUND Oocyte retrieval failure following an ovarian hyperstimulation protocol is uncommon in assisted reproductive technology (ART) programs. We analyzed the predictive factors for oocyte retrieval failure following controlled ovarian hyperstimulation (COH) with gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist protocols in ART programs. METHODS This study was a retrospec...

BACKGROUND To test whether a site-specific hysteroscopic biopsy-induced injury in the endometrium during the controlled ovarian hyperstimulation cycle improves subsequent embryo implantation in patients with repeated implantation failure, a total of 30 patients who have had good responses to controlled ovulation stimulation but have failed to achieve pregnancy after two or more transfers of goo...

With the advent of recombinant follicle stimulating hormone (FSH) and luteinizing hormone (LH), free from contamination with each other (Loumaye et al., 1995), it is possible to dissect the individual contributions of FSH and LH to the regulation of ovarian function and to define optimal gonadotrophin usage in controlled ovarian hyperstimulation (COH) (Hillier, 1994). Basic and clinical researc...

Background: The objective of this study is to establish importance of anti-FSH antibodies in IVF outcome. Materials and Methods: This research was designed based on evaluation of several articles from 2000 till 2012 about anti-FSH antibodies in IVF outcome. Results: Serum concentrations of anti-FSH IgG and IgA were linearly associated with poorer ovarian stimulation outcome. For example 1.0 AU ...

Materials and Methods: This prospective study was performed on 70 patients undergoing controlled ovarian hyperstimulation and followed by the IVF Department between February 2009-June 2009. Age, body mass index (BMI), basal levels of folliclestimulating hormone (FSH), estradiol (E2), luteinizing hormone (LH), ovarian volume, and number of antral follicles were compared between the good responde...

Objective Coasting can reduce the ovarian hyperstimulation syndrome (OHSS) risk in ovulation induction cycles before intracytoplasmic sperm injection (ICSI). This study aimed to investigate the effect of gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist protocols to controlled ovarian hyperstimulation (COH) cycles with coasting on the parameters of ICSI cycles and the outcome. M...

OBJECTIVE To determine whether the short or long protocol for controlled ovarian hyperstimulation works better in older patients undergoing IVF. DESIGN Controlled, randomized study. SETTING A single private IVF center. PATIENT(S) Two hundred twenty infertile women aged > or = 40 years undergoing IVF. INTERVENTION(S) At their first IVF cycle, the women were randomized into two study grou...

STUDY QUESTION Does ovarian hyperstimulation, the in vitro procedure, or a combination of these two negatively influence blood pressure (BP) and anthropometrics of 4-year-old children born following IVF? SUMMARY ANSWER Higher systolic blood pressure (SBP) percentiles were found in 4-year-old children born following conventional IVF with ovarian hyperstimulation compared with children born fol...

Eleven patients underwent controlled ovarian hyperstimulation yielding 72 embryos for evaluation. Mean nitric oxide metabolite levels in the insemination media were 2.6 times higher in embryos that progressed to blastocysts by culture day 5 than in those that did not. A comparison of the receiver operating characteristic curves between morphological predictors and nitric oxide metabolite levels...
