Body has defense mechanisms against oxidants in the form of both enzymatic and non enzymatic antioxidants. Oxidants have both physiological and pathological role in female reproduction. Oxidative stress causes damage to the ovaries, oogonia and ovulation as well as in implantation procedures. A study was undertaken to evaluate the polycystic ovary syndrome (PCOS) induced stress in ovarian and u...

OBJECTIVE To evaluate the impact of luteal phase support with vaginal progesterone on pregnancy rates in the intrauterine insemination (IUI) cycles, stimulated with clomiphene citrate and human menopausal gonadotropin (hMG), in sub fertile couples. MATERIALS AND METHODS This prospective, randomized, double blind study was performed in a tertiary infertility center from March 2011 to January 2...

BACKGROUND N-acetyl cysteine (NAC) was proposed as an adjuvant to clomiphene citrate for ovulation induction in patients with polycystic ovary syndrome (PCOS) without clomiphene citrate resistance. OBJECTIVE To evaluate the effect of NAC on pregnancy rate in PCOS patients who were candidates for intrauterine insemination. MATERIALS AND METHODS In this randomized clinical trial, 97 PCOS wome...

INTRODUCTION A heterotopic pregnancy is defined as the presence of a combined intrauterine and ectopic pregnancy. Its estimated incidence is accepted as between 1/7000 and 1/30,000 pregnancies. It is also reported to be as high as 1% after the use of assisted reproductive technology, but Clomiphene Citrate which increases the rate of twinning, could be associated with a heterotopic pregnancy ra...

A total of 811 intrauterine insemination (IUI) cycles in which clomiphene citrate/human menopausal gonadotrophin (HMG) was used for ovarian stimulation were analysed retrospectively to identify prognostic factors regarding treatment outcome. The overall pregnancy rate was 12.6% per cycle, the multiple pregnancy rate 13.7%, and the miscarriage rate 23.5%. Logistic regression analysis revealed fi...

There is currently no effective treatment for the Ebola virus (EBOV) thus far. Most drugs and vaccines developed to date have not yet been approved for human trials. Two FDA-approved c-AbI1 tyrosine kinase inhibitors Gleevec and Tasigna block the release of viral particles; however, their clinical dosages are much lower than the dosages required for effective EBOV suppression. An α-1,2-glucosid...

A signalling molecularly imprinted polymer was synthesised for easy detection of tamoxifen and its metabolites. 6-Vinylcoumarin-4-carboxylic acid (VCC) was synthesised from 4-bromophenol to give a fluorescent monomer, designed to switch off upon binding of tamoxifen. Clomiphene, a chlorinated analogue, was used as the template for the imprinting, and its ability to quench the coumarin fluoresce...

BACKGROUND Despite the recognized role of hormones in the aetiology of breast cancer, there has been little evaluation of hormonal preparations used to treat infertility. METHODS A retrospective cohort study of 12,193 women evaluated for infertility between 1965 and 1988 at five clinical sites identified 292 in situ and invasive breast cancers in follow-up through 1999. Standardized incidence...

Background: Clomiphene citrate (CC) is still holding its place as the first-line treatment for induction of ovulation in polycystic ovary syndrome (PCOS) patients.  Objective: to assess effect extended clomiphene on pregnancy outcomes resistant PCOS. Patients and methods: this study was conducted 48 PCO patients with CC resistance attended Obstetrics Gynecology Outpatient Clinic at Menoufia U...
