Various assisted reproductive techniques have been developed and refined to obtain a large number of offspring from genetically superior animals or obtain offspring from infertile (or subfertile) animals. The embryo transfer is one assisted reproductive technique developed well, aimed at increased productivity of selected females, disease control, importation and exportation of livestock, rapid...

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...

Objective The success of assisted reproductive technology (ART) may be influenced by male and female lifestyle-related factors. The objective of this pilot study was to evaluate the feasibility of conducting a larger prospective cohort study, which will aim at determining the independent contribution of male and female lifestyle-related factors to ART success. The study was also designed to exa...

heterotopic pregnancy (hp) is the simultaneous occurrence of intra- and extrauterine pregnancies. it is a rare event in spontaneous pregnancies with an incidence of less than 1:15000 however the frequency has increased to 1% in accordance with the widespread use of assisted reproductive techniques (art). the pre-operative diagnosis of this condition is generally difficult and it would be life t...

Bilateral tubal occlusion due to sexually transmitted diseases and pregnancy-related infections is the most common cause of inferti...

Although the presence of spermatozoa with an abnormally large head is rare, it is associated with low fertility or even total infertility. We reviewed the literature on assisted reproductive technology (ART) strategies and outcomes for men with large-headed spermatozoa. We also discuss additional analyses that can usefully characterize sperm defects and help with the choice between intra-couple...
