BACKGROUND The present study aimed to analyze the prognostic value of sperm morphology , total motile sperm count (TMSC) and the number of motile sperm inseminated (NMSI) on the outcome of intrauterine insemination (IUI). MATERIALS AND METHODS This cross sectional study was carried out 445 women undergoing 820 IUI cycles. All of the patients underwent(More)
BACKGROUND Recurrent spontaneous abortion (RSA) and in vitro fertilization (IVF) failure with unknown causes are the controversial issues that are probably related to the immune system. OBJECTIVE To compare circulating NK cells expressing activation and inhibition surface markers between patients with RSA and IVF failure with those of healthy multiparous(More)
This study aimed to assess the morphological changes in neonate vitrified testicular grafts after host treatment with melatonin. Neonate vitrified testes, candidates for transplantation to treated and nontreated groups receiving melatonin, were thawed in media containing or not containing 100 μm melatonin. Following transplantation, melatonin (20 mg kg(-1)(More)
The follicular fluid (FF) is produced during folliculogenesis and contains a variety of proteins that play important roles in follicle development and oocyte maturation. Age-related infertility is usually considered as a problem that can be solved by assisted reproduction technology. Therefore, the identification of novel biomarkers that are linked to(More)
Recent studies support the concept that NK cells play an important role in the success or failure of embryo implantation. Recurrent spontaneous abortion (RSA) is the most common complication of pregnancy. Some couples suffer from infertility of unknown cause. In vitro fertilization (IVF) is one of the useful treatment methods used for treatment of this type(More)
The aim of this study was to investigate whether the endometrium of women with unexplained infertility differs in the presence of the beta 3 (beta3) integrin molecule from the endometrium of normal fertile women. In a retrospective case-control study 30 endometrial biopsies from hysterectomies with nonendometrial pathology and 30 endometrial samples from(More)
BACKGROUND Preterm labor is the leading cause of infant morbidity and mortality so it may be necessary to administer tocolytics for treatment of it. OBJECTIVE The aim of this study was to compare the efficacy and safety of magnesium sulfate and nifedipine in the management of preterm labor. MATERIALS AND METHODS 100 women with documented preterm labor(More)
To assess the effectiveness of tamoxifen administration with letrozole in the context of intrauterine insemination (IUI) cycles. This prospective double-blinded study included 130 patients. After randomization, 65 patients in group A received letrozole + tamoxifen and human menopausal gonadotropin (HMG), whereas 65 patients in group B received placebo(More)
AIM This study aimed to evaluate the efficacy of ketotifen on sperm motility of asthenospermic infertile men. SETTING AND DESIGN It is a prospective study designed in vivo. MATERIALS AND METHODS In this interventional experimental study, a total of 40 infertile couples with asthenospermic infertility factor undergoing assisted reproductive technology(More)
BACKGROUND Some studies propose that changes in leptin concentrations (above or under the normal range) result in infertility. Therefore, we investigated serum and follicular fluid leptin concentrations in infertile women with polycystic ovary syndrome (PCOS). OBJECTIVE To study serum and follicular fluid leptin concentrations in infertile women with(More)
