On the priority of V.S. Gruzdev in the experiment on in vitro fertilization

Among the many methods of teaching students, special attention is drawn to becoming a specialist through the implementation of scientific research. V.S.Gruzdev, having mastered under the guidance of Professor V.A.Manassein the first skills of scientific research, widely used them in his development as an obstetrician-gynecologist. Later he formed his own scientific school, which still exists today. One of his early works was the study of artificial insemination in mammals. This research, ahead of its time, marked the beginning of the study of in vitro fertilization. He revealed an important regularity in the development of a fertilized egg when it is planted in the oviduct. Other contemporary embryologists also spoke about this feature, mentioning that V.S.Gruzdev became the first scientist who described it. It is important that Viktorin Sergeevich proposed a plan to resolve the problem of infertile marriage, through his experiments as a result of his research, followers were able to significantly increase the number of pregnancies that occurred as a result of the treatment of obstruction of the fallopian tubes and identify problems associated with the pathology of spermatogenesis in men, and their role in an infertile marriage. Professor P.V.Manenkov, being a student and follower of V.S.Gruzdev, continued the work of his teacher and was also able to further participate in the development of a bill draft on heteronomous conception.
