Comparative Characteristic of the Methods of Isolation of Oocytes and Spermatozoa in Laboratory Animals (Review).

Over the past decade, there has been an increasing trend in the use of assisted reproductive technologies, which have significantly expanded the opportunities to overcome the problem of infertility. However, the problem of increasing the effectiveness of in vitro fertilization remains open. Isolation of germ cells from animals is a necessary process for various experimental studies. Animal germ cells can be used in experiments to study physical, chemical, genetic, immunological, and microbiological factors affecting reproduction efficiency and for the development of techniques that increase the effectiveness of in vitro fertilization. All of the above determines the relevance of studying existing methods of oocyte and sperm isolation for experimental in vitro studies. Here we discuss the existing methods of sperm and oocyte isolation from animals and their advantages and disadvantages, and also substantiate priority methods for use.
