Gonadotropin-releasing hormone (GnRH) antagonists, which became commercially available from 1999, have been used for the prevention of premature luteinizing hormone (LH) surges in controlled ovarian stimulation for in vitro fertilization or intracytoplasmic sperm injection. This review focuses on the recent literature on the use of GnRH antagonists and provides guidelines for optimal use in lig...

background: anti-mullerian hormone (amh) levels may represent the ovarian follicular pool and could be a useful marker of ovarian reserve. the clinical application of amh measurement has been proposed in the prediction of quantitative and qualitative aspects in assisted reproductive technologies. objective: this study aimed to assess the relationship between the serum levels of amh and results ...

Suppression of endogenous hormone production by gonadotrophin-releasing hormone (GnRH) agonists followed by controlled ovarian hyperstimulation (COH) with human gonadotrophins, especially the so-called 'long protocol' has developed from second-line into first-line therapy. Due to this attitude premature luteinization can be safely avoided, enhancing therapeutic efficacy. Recombinant preparation...

The aim of this investigation is to determine the correlation of color Doppler (CD) and color Doppler Energy (CDE) imaging and measurements of ovarian stromal blood flow prior to controlled ovarian hyperstimulation (COH), predictors of success of COH and numbers of oocyte retrieved, especially in group of poor responders. Fifty-two patients on IVF treatment were included in this prospective cli...

Background This research investigated the response of vascular active factors, vascular endothelial growth factor (VEGF) and angiotensin-II (AT-II) to ovarian stimulation during 24 hours in patients with polycystic ovary syndrome (PCOS). MaterialsAndMethods In this clinical trial study, 52 patients with PCOS and 8 control cases were stimulated with human chorionic gonadotropin (HCG) on the 4th ...

Salpingectomy is largely used in case of hydrosalpinx in infertile women scheduled for assisted reproductive technologies (ART), whereas there is no consensus on its role in absence of hydrosalpinx. The current is a systematic literature review to collate all available evidence regarding salpingectomy as fertility enhancement procedure before ART in infertile patients. Our primary endpoint was ...

The current study assessed the usefulness of in vivo high frequency ultrasound imaging (ultrasound biomicroscopy, UBM) for dynamic study of the ovarian structures in laboratory rodents. UBM imaging was performed, by using a 40 MHz probe, in 12 C57BL/6J female mice and four Wistars female rats at breeding age and during different reproductive periods. UBM provided outstanding images of both foll...
