Oxidative stress (OS) has been recognized as a significant cause of suboptimal assisted reproductive outcome. Many of the sperm preparation and manipulation procedures that are necessary in the in vitro environment can result in excessive production of reactive oxygen species (ROS) thereby exposing the gametes and growing embryos to significant oxidative damage. Antioxidants have long been util...
Introduction Although embryo transfer provides a means of obtaining pregnancies from some mares that might not otherwise be capable of producing offspring, some mares cannot provide embryos for transfer. Mares in which embryo transfer may not be successful include those with: 1) failure of ovulation, 2) chronic endometritis (uterine inflammation), or 3) anatomical problems (e.g., cervical adhes...
Recently larger numbers of women of advanced age are referring to fertility centers. Although there may be no age restriction for women who are naturally able to and want to be pregnant, using assisted reproductive techniques for women of advanced age is medically and ethically disputed, and this question is always raised: "Should there be an age limit for accessing assisted reproductive techni...

background: objective: this study aimed at investigating the side effects and hemodynamic effects of using thiopental sodium and propofal as well as effects of these drugs on pregnancy outcome in art cycles. materials and methods: in this double blinded) randomized controlled trial, 90 woman candidate for art were randomly divided into two groups. 47 patients received propofol (2.5 mg/kg) a...
Nuclear transfer procedures have been recently applied for clinical and research targets as a novel assisted reproductive technique and were used for increasing the oocyte activity during its growth and maturation. In this review, we summarized the nuclear transfer technique for germinal vesicle stage oocytes to reconstruct the maturation of them. Our study covered publications between 1966 and...
The ultrastructural analysis of oocytes and ovarian follicles has been used to evaluate the effects of assisted reproductive techniques, such as cryopreservation or in vitro oocyte maturation. It also benefits the understanding of such complex mechanisms that occur during folliculogenesis. From the beginning of primordial follicles growth until oocyte maturation in preovulatory follicles oocyte...
