Background: Polycystic ovary syndrome (PCOS) is multifaceted and includes reproductive, metabolic, and general health disorders, so employing different animal models is needed to study the syndrome. Use of an aromatase inhibitor, letrozole, on adult female rats produces a phenotype remarkably similar to that of PCOS. Licorice has been used in treating women infertility for thousands of years. L...

Background: The effect of electromagnetic field (EMF) as an environmental factor on different organs including female reproductive system is of critical concern. In view of the fact that embryo fetuses and young, growing animals are more susceptible to any xenobiotic during gestational and lactation stages of gonadal development may it lead to permanent damage to the gonads. The early phases of...

Background: Human chorionic gonadotropin (hCG) is a member of glycoprotein hormones family consist of two different non-covalently heterodimeric chains: alpha and beta subunits with 92 and 145 amino acids respectively. This hormone plays an important role in human reproduction and physiology especially for maintenance of the corpus luteum during the first months of pregnancy Materials and Metho...

PURPOSE To evaluate the prevalence of common mental disorders in women diagnosed with polycystic ovary syndrome as compared with paired controls without this syndrome. METHODS Cross-sectional study with a Control Group examining women between the ages of 18 and 30 who did not use antidepressants and who sought the Gynecology Service of the researched sites. For every woman diagnosed with the ...

Background: Follicle stimulating hormone (FSH) receptor plays an important role in FSH signaling during reproductive development. Any changes in FSHR gene is resulted in alteration of amino acid in protein chain, consequence to affect the binding affinity, intracellular signaling and expression levels of FSHR. FSHR polymorphisms can be involved in etiology of many reproductive disorders such as...

Background: Nicotine can induce sub fertility and infertility in females. The aim of this study was to determine the effect of nicotine on follicular cells proliferative activity in mouse ovary. Materials and Methods: Female adult NMRI mice were divided into two groups. Animals in control group received vehicle, however in experimental group, animals were treated with 0.4mg/kg of nicotine for 1...

Background Whole ovary cryopreservation has been proved to be a feasible technique in fertility preservation. The normal ovarian cortex contains a large population of primordial follicles, this characteristic make them far more tolerant to cryoinjury. Researchers have used different cryoprotectants and various techniques to improve cryopreservation. It is plausible that inclusion of an antioxid...

Background: To determine the effect of ovarian stimulation on the height of the epithelial cells of fallopian tubes and development of ovarian follicles and corpus luteum in NMRI mice. Materials and Methods: Forty female NMRI mice of 6 to 8 weeks were selected and divided into 4 groups: control group, 10 mice that were injected with saline. The second group of 10 mice that were injected with 7 ...
