orally active aromatase inhibitors (ais) have gained attention for treatment of infertile women with endometriosis in whom aromatase p450 is aberrantly expressed. this review aimed to critically appraise and summarize the available evidence concerning the use of ais for management of endometriosis-associated infertility. pubmed was searched to may 2015 with the following key words: endometriosi...

objective: polycystic ovary syndrome (pcos) is highly associated with anovulatory infertility, features of the metabolic syndrome, including obesity, insulin resistance and dyslipidemia. serum concentrations of high sensitive c- reactive protein (hs-crp) were significantly higher in obese than in non-obese pcos patients at baseline suggesting that the relationship between elevated hs-crp levels...

Background Implantation failure is the most important cause of recurrent in vitro fertilization/intra cytoplasmic sperm injection (IVF/ICSI) failure. Several reports suggest that intercourse during the peritransfer period might improve pregnancy rates. This study is designed to determine whether intercourse during the peritransfer period will improve pregnancy and implantation rates in patients...

This study aimed to evaluate if single medium is better than sequential medium at improving ongoing pregnancy rates in patients undergoing assisted reproductive technology (ART) procedures. The data featured in this meta-analysis were extracted from four randomized controlled trials yielded from a systematic search carried out on electronic databases. The primary endpoint was ongoing pregnancy ...

OBJECTIVE To determine the clinical potential of donor-oocyte cryopreservation and thaw techniques for recipient patients. DESIGN Institutional review board-approved prospective study of donor oocyte cryopreservation. SETTING A large, private infertility center. PATIENT(S) Four anonymous oocyte donors underwent ovarian hyperstimulation for the purpose of oocyte retrieval and cryopreservat...

This study was conducted to report the clinical-pregnancy outcome after vitrification of the blastocysts produced from in vitro maturation cycles. The survival rate after thawing was 92.0% (92/100). The clinical-pregnancy and implantation rates were 43.8% and 23.6%, respectively. These results suggest that the blastocyst-stage embryos produced from in vitro maturation cycles can be safely cryop...

Background: To investigate the effect of administering piroxicam on improving the success rate of IUI cycles in those suffering from unexplained infertility. Materials and Methods: This was a randomized clinical trial being performed at Ghadir Mother and Child Hospital and Motahari clinics of Shiraz University of Medical Sciences. We included 260 women with unexplained infertility selected for ...

background: although intrauterine insemination (iui) is one of the most common methods which is used for male factor and unexplained infertility the relative influence of various semen parameters on the likelihood of a successful outcome is controversial. several semen parameters have been evaluated as predictors of a successful outcome with intrauterine insemination. objective: to evaluate the...

in sheep industry, pregnancy rate after artificial insemination (ai) declines due to the complex anatomy of the cervix in ewes, such that it might prevent effective intrauterine insemination. at estrus, cervical relaxation occurs to some degree in ewes, which is regulated by the changes in the levels of reproductive hormones. this study aimed to evaluate the effects of estradiol and intravenous...

lactatingdairy cows (n=177) fed with grass and corn silage ad libitum kept in pasture, were randomly assigned to evaluate how urea nitrogen in plasma and milk can be related to their pregnancy rate. blood and milk samples were collected on the artificial insemination (ai) day to evaluate plasma urea nitrogen (pun) and milk urea nitrogen (mun) as well as progesterone levels, excluding cows with ...
