BACKGROUND The extremes of BMI are associated with an increased risk of miscarriage both in spontaneously conceived pregnancies and after fertility treatment. The aim of the present study was to study the effect of BMI on miscarriage rate (MR) in fresh IVF/ICSI, and in spontaneous and hormonally substituted frozen-thawed embryo (FET) cycles. METHODS Analysis was carried out on 3330 first preg...

Abstract Background Along with progress in embryo cryopreservation, especially the vitrification, freeze all strategy has become more acceptable than ever. Some studies have found comparable or higher live birth rate frozen transfer (FET) fresh transfer(ET)in gonadotropin releasing hormone antagonist (GnRH-ant) protocol. However from our literature research, there been no reports about comparis...

BACKGROUND Advances in embryo culture technology and cryopreservation have led to a shift in in vitro fertilization (IVF) from early fresh or frozen-thawed cleavage embryo transfer to fresh or frozen-thawed blastocyst stage transfer. OBJECTIVE To compare the clinical outcomes of fresh embryo transfers and frozen-thawed embryo transfers. MATERIALS AND METHODS In this retrospective case contr...

BACKGROUND The purpose of the study was to compare clinical pregnancy and delivery rates with fresh and frozen embryo transfer in patients admitted to Shiraz- Human Assisted Reproductive Center with ovarian hyperstimulation syndrome (OHSS). METHODS OHSS patients randomly divided in two groups, group A (n=50) with fresh embryo transfer and group B (n=50) with frozen embryo transfer. We used vi...

The aim of this study was to analyze whether GnRH agonist treatment before frozen-thawed embryo transfer (FET) improved the pregnancy outcomes of adenomyosis patients and to study the effects of GnRH agonists to the health of offspring. This study was a retrospective analysis of 139 patients who underwent in vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI) between Jan 2011 and D...

Background: Embryo cryopreservation is an important part of assisted reproductive technologies to increase cumulative pregnancy rate in clients. However, clinical settings, embryos can be subjected repeated cryopreservation-warming cycles due certain circumstances. There are limited data on the effect such may have success embryo transfer procedures. In this study, we investigated cleavage-stag...
