Serum progesterone levels greater than 32.5 ng/ml on the day of embryo transfer are associated with lower live birth rate after artificial endometrial preparation: a prospective study.

Background: Previous observational studies have highlighted the negative effects of serum hormone levels at the minimum threshold during frozen embryo transfer (FET) cycles. However, still the questions regarding the maximum threshold level, and the highest allowed dosage of hormonal medications remain unresolved. The present study was conducted to determine whether there is any relationship between the serum progesterone and estradiol levels on the day of ET, and live birth rate (LBR) in patients receiving HRT in FET cycles.

The efficacy of gonadotropin-releasing hormone (GNRH) agonist before frozen embryo transfer in improving pregnancy outcome and decreasing miscarriage rate in hyperandrogenic polycystic ovary syndrome women: a randomized clinical trial.

Background: The hyper androgenic status is a major complication of polycystic ovarian syndrome (PCOS) that deteriorates endometrial function and increases miscarriage rate. This study was conducted to investigate the efficacy of GnRH agonist before frozen-thawed embryo transfer in improving pregnancy outcome in infertile women with PCOS.

Methods: This single-blind, randomized controlled trial was performed at Dr Shariati hospital and Omid Fertility Clinic in Tehran, Iran.

Malondialdehyde levels in sperm and seminal plasma of asthenozoospermic and its relationship with semen parameters.

Background: Toxic lipid peroxides are known to cause various impairments of sperm cells and may play a major role in the etiology of male infertility. We determined the level of lipid peroxidation as indicated by malondialdehyde (MDA) in the spermatozoa and seminal plasma of asthenozoospermic and normozoospermic males.

Methods: MDA of spermatozoa and seminal plasma was determined in 35 asthenozoospermic and 15 normozoospermic men by spectrofluorometry.
