Endometriosis is a multifactorial gynecological condition characterized by the presence of ectopic endometrial and stromal tissue outside the uterus. Free radicals and Oxidative stress have been proposed to be involved in the pathogenesis of the endometriosis. It has been shown that mitochondrial DNA (mtDNA) is particularly susceptible to oxidative damage(More)
BACKGROUND The prevalence of metabolic syndrome (MetS) in polycystic ovary syndrome (PCOS) has been studied in different populations, but their results were so controversial regarding Iranian women. These controversial data indicated the need for more investigation of MetS characteristics in PCOS patients in our population. So this study aimed to evaluate(More)
BACKGROUND AND OBJECTIVE Sperm morphology analysis (SMA) is an important factor in the diagnosis of human male infertility. This study presents an automatic algorithm for sperm morphology analysis (to detect malformation) using images of human sperm cells. METHODS The SMA method was used to detect and analyze different parts of the human sperm. First of(More)
BACKGROUND Our purpose was to compare the efficacy of extra-amniotic saline infusion plus high dose oxytocin with prostaglandin E2 intracervical gel (Dinoprostone) for preinduction cervical ripening. MATERIAL/METHODS 166 nulliparous women with term pregnancies, vertex presentation, intact membranes and a Bishop score < or = 4 referred for labor induction(More)
BACKGROUND Pregnancy is a successful transplantation. The factors evading rejection of the fetus are poorly understood. Recently an interest has grown, in HLA-G molecules as one of these factors. Since these antigens are mainly expressed on the surface of cytotrophoblasts that are in direct contact with maternal tissues, it has been suggested that these(More)
About 10%-15% of conceptions are lost spontaneously prior to 20 weeks. Apart from the clinical problems, genetic variations have also been proposed as a susceptibility factor to miscarriage. Glutathione peroxidase 1 (GPX1) and catalase (CAT) encode two antioxidant enzymes that detoxify H2O2 and protect the cells from oxidative damage. A functional(More)
BACKGROUND Abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. OBJECTIVE In this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (HCG) administration.

Endometriosis is defined as the presence of ectopic endometrial glands and stroma outside of the uterine cavity. Recent studies have shown that the oxidative stress causes irreparable damage, which leads to oxidative enzymopathies. Catalase gene encodes an antioxidant enzyme, detoxifying hydrogen peroxide to H2O and O2. The aim of this study was to(More)
OBJECTIVE To determine the association between serum 25 - hydroxy vitamin D concentration and anthropometric indices in patients with polycystic ovarian syndrome (PCOS). MATERIALS AND METHODS This is a descriptive cross - sectional study which was carried out on women with PCOS aged 19-39 years old referred to an infertility clinic of Alzahra Hospital,(More)
BACKGROUND Obesity is an independent risk factor of preeclampsia with unknown mechanism and hyperlipidemia might be a probable case of it. OBJECTIVE The objective of this study was to determine the role of hyper-triglyceridemi in association with high prepregnancy body mass index and the risk of preeclampsia. MATERIALS AND METHODS The authors conducted(More)
