Ultrasound method of monitoring follicles and oocytes of cumulus complexes in dogs during ART

Rapid progress in the field of ultrasound imaging is the result of continuous modernization of equipment, development of new methods, expansion of diagnostic capabilities. Modern ultrasound scanners allow to obtain a more detailed image, giving a lot of information about the state of organs. Dynamic examination of the ovaries has a number of advantages, which include: high availability, no need for preparation, the ability to observe the transformation of the gonads during the sexual cycle, high information content, low cost and harmlessness of the study. The study was performed on 101 females: 89 females before the artificial insemination procedure and 12 females before the embryo washout procedure. As a result of the work, an ultrasonographic picture of follicular dynamics, OCC formation, ovulation and early postovulatory period in comparison with the progesterone level was established. An algorithm for monitoring females during ART has been developed, which allows increasing the percentage of successful fertilization and obtaining a larger number of embryos of the desired stage of development.
