All existing classifications of barreness at men are based on different principles. In some of them as the main sign of infringement of fruitfulness at men is estimated a condition ejakuljata. So, Kuhnelt (1953), S.A.Kagan (1974) in the classification was allocated with five kinds of changes of sperm:

Normozoospermija - concentration spermatozoonov more than 60 million/ml, oligozoospermija various degree depending on concentration spermatozoonov in ejakuljate: 1st degree - 60-30 million/ml; 2nd degree-30 - 10 million/ml; 3rd degree - less than 10 million/ml, azoospermija (aspermija) - spermatozoony in ejakuljate are not found out, nekrospermija (akineticheskaja sperm) - all spermatozoony are motionless and cannot be recovered,

aspermatizm, or full absence ejakuljata.

It is possible to name the Resulted classification symptomatic as in it change degree ejakuljata is reflected mainly, are not considered etiologicheskie and pathogenetic features of its infringements. It is applicable to an estimation ejakuljata, but does not focus on an individualization of medical actions. Besides in it, from our point of view, terminological discrepancies are admitted, in particular.aspermija, nekrospermija and aspermatizm are treated by authors originally.

Hudson and co-authors (1980) named the classification etiologicheskoj, on have allocated in it anatomic structures in which are formed and on which move ahead spermatozoony, and some conditions of infringement of fruitfulness.
