The current population of wisents (Bison bonasus, Linnaeus 1758) originates from only 12 individuals that survived World War II in zoos and private enclosures. For better preservation genetic variability, research is being conducted to introduce assisted reproductive techniques this species. In article, we describe the state knowledge prospects for further development field. article divided int...

Commercialization of animal biotechnologies, including those related to reproduction [also known as assisted reproductive techniques (ARTS)], is an increasing reality in developing countries, following the enormous flow of information around us and the increasing global commercial interests in areas where cattle production has its major assets. The present review discusses the achievements of v...

Assisted reproductive technology has made great progress during the last three decades. After the initial enthusiasm, many ethical, legal and social issues related to the application of these procedures began to evolve. Multifetal pregnancy and fetal reduction, embryo cryopreservation, preimplantation genetic diagnosis, risks of birth defects and other adverse outcome associated with assisted r...

background: more and more infertile patients have accepted the assisted reproductive technique (art) therapy. concerns have been raised over an increased risk of adverse maternal outcomes in art populations as compared with natural conception (nc). objective: the aim was to improve the art in clinicial work and to reduce the incidence of pregnancy complications in art group according to analyzi...

background: implantation is one of the essential steps for the success of assisted reproductive techniques (art). their success depends on three main factors: embryo quality, endometrial receptivity (er), and synchrony between embryo and endometrium. there are various factors that regulate the complex process of implantation. in this regard, one may refer to human chorionic gonadotropin (hcg) a...

The effect of smoking on Assisted Reproductive Technology (ART) results in male was considered as a deleterious factor in pregnancy outcome among IVF patients. Male smoking is associated with lower success rate in ICSI and IVF couples. Smoking significantly decreased live birth rates and has a deleterious effect on sperm’s DNA. This study was designed to evaluate the effect of male cigarettes s...

The ability to precisely measure circulating levels of hormones is a foundation of modern endocrinology. For assisted reproductive technologies such as in vitro fertilization (IVF), accurate determination of circulating levels of estradiol are crucial for patient management, retrieval of fertilizable oocytes, and successful pregnancy outcome. For many years, circulating levels of estradiol were...

Assisted reproductive technologies (ART) are widely used to treat infertility. Emerging evidence suggested that ART was associated with perinatal or neonatal problems, however, little is known about the ART related risk factors. Here using 21136 ART cases, we determined the impacts of parental physiological conditions in the ART mediated pregnancy outcomes. In addition, we further evaluated the...
