INFLUENCE OF DONORS ON THE EFFICIENCY OF OBTAINING EMBRYOS IN CULTURE IN VITRO
In the process of research the influence of individual characteristics of donors on the efficiency of aspiration and obtaining embryos in culture in vitro was studied. As a result no regularity has been established for the effectiveness of aspiration and obtaining embryos in culture in vitro depending on their number. Thus, the number of aspirated follicles, depending on the donor, ranged from 3.7 to 8.2, the yield of viable oocytes from 55.1% to 96.4%, the level of cleavage from 41.7% to 95.1%, and the yield of embryos from 2.1% to 32.4%. There is a tendency for the average efficiency indicators to be increased as the aspiration serial number increases. Thus, the average yield of oocytes with an increase in the number of aspirations from one to nine was, depending on the donor, 2.3-4.8, and the yield of embryos was 0.1-0.7, with an increase in the number of aspirations from 11 to 14, -2.4-5.3 and 0.3 -0.7 and with an increase in number of aspirations from 15 to 22 - 3.9-9.7 and 0.6-1.8, respectively.
