The birth of a healthy child in a married couple with a history of multiple unsuccessful attempts at ART by selecting sperm on oocyte-cumulus complexes. Case report

Abstract

In male infertility, couples must use assisted reproductive technologies with the intracytoplasmic sperm injection (ICSI) technique. A significant disadvantage of ICSI is bypassing natural selection barriers since selective processes in the female reproductive tract are replaced by the choice of an embryologist based on sperm motility and morphological criteria. Various selection methods are being actively studied, bringing fertilization by ICSI closer to physiological, ensuring the selection of sperm with high DNA quality and good potential for fertilization. The article presents a clinical case of the birth of a healthy child in a married couple with severe male infertility and many ineffective attempts at assisted reproductive technologies using the method of sperm selection on oocyte-cumulus complexes. The child is physically healthy and develops according to age.
