Pregnancy is a condition that favours oxidative stress. The aim of this study was to evaluate the oxidant and antioxidant status by measuring glutathione peroxidase (GSH-Px), catalase (CAT) activities and malondialdehyde (MDA) and glutathione (GSH) concentrations before and during pregnancy in ewes. Twelve healthy female and two healthy male Awassi sheep, aged 4-5 years, weighing approximately ...

background:   objective: the purpose of this study was to compare the predictive value of progesterone level on ivf success in women with infertility due to tubal factor or pcos.   materials and methods: in a stratified cohort study, we assigned 76 infertile women of 20-38 years old who referred to women hospital into two equal groups with fallopian tube factor infertility and pcos. we measured...

BACKGROUND It is of critical importance to evaluate the role of environmental chemical exposures in premature birth. While a number of studies investigate this relationship, most utilize single exposure measurements during pregnancy in association with the outcome. The studies with repeated measures of exposure during pregnancy employ primarily cross-sectional analyses that may not be fully lev...

we report a spontaneous unilateral live tubal twin pregnancy in a patient with a history of previous ectopic pregnancy (ep) and tubal surgery. transvaginal ultrasound showed one pregnancy sac containing two fetal poles with cardiac activity, which appeared to be sited within the right adnexum. the right tubal ep was removed by salpingectomy. ultrasound findings of suspected adnexal mass and fre...

background: human fertility has been declined all over the world. advanced women’s age is one of the most important factors in determining the success of reproduction and ageing has negative impact on art outcome and advanced female age decreases the chance of live birth rates achieved using art, especially after 40 years of age. objective: to evaluate art outcomes regarding to pregnancy, abort...

Pregnancy increases the urinary excretion of chemicals in women and rodents. It is unknown whether the enhanced clearance of drugs during pregnancy involves changes in the expression of transporters that mediate chemical secretion and reabsorption. The purpose of this study was to quantify the mRNA and protein expression of efflux transporters in kidneys from virgin and pregnant mice on gestati...

BACKGROUND Despite major advances in assisted reproductive techniques, the implantation rates remain relatively low. Some studies have demonstrated that intrauterine infusion of granulocyte colony stimulating factor (G-CSF) improves implantation in infertile women. OBJECTIVE To assess the G-CSF effects on IVF outcomes in women with normal endometrial thickness. MATERIALS AND METHODS In this...
