Male factor of sterility: algorithm of laboratory diagnosis of the causes (part 2)
Previously, the topics of laboratory diagnosis were covered: assessment of the male androgenic status: what to choose - total or free testosterone; or use an estimated indicator - free testosterone index; what is important to consider when referring to an assessment of testosterone levels; how to correctly interpret the result, taking into account the dependence on a number of factors; why it is necessary to at least twice assess the level of testosterone; what are the criteria for making a diagnosis of male hypogonadism; what further examination should be carried out after diagnosis. In this article, we continue to consider laboratory algorithms for diagnosing a variety of causes of hypogonadism. Separately, we will focus on spermogram as a test, which allows a comprehensive assessment of the functioning of all systems responsible for the formation of sperm.
