Diagnosis of male infertility is a complex of laboratory and instrumental studies, with the help of which it is possible to identify the reason for the problems encountered during the conception of a child. To successfully overcome the problem, it is recommended to undergo a comprehensive examination, including andrologist examination, analysis of hormones in men, spermogram and others. In approximately 40-45% of cases of childless marriages, the responsibility lies precisely with the man, since male infertility is a common occurrence.
