Special tests on impregnating activity spermatozoonov. At normal kliniko-laboratory data at both spouses and absence of conception, i.e. In the presence of forms of barreness difficult to explain, special tests on biological activity spermatozoonov which concern test on resistance, test on oxidation-reduction activity spermatozoonov, test of a pas compatibility and penetratsionnuju ability are made.

Test on resistance spermatozoonov. Stability and viability spermatozoonov in adverse conditions characterises their physiological full value and biological activity. It is known, that in a vagina there are adverse factors: the sour environment, the raised temperature, microbic agents. Therefore the stability indicator spermatozoonov to adverse conditions reflects their ability to fertilisation.

We agree with S.A.Kagana's (1974) opinion, that V.K.Milovanova's method is better than others estimates stability spermatozoonov to extreme conditions. It is considered, that at normozoospermii,

I.e. Normal fruitfulness, resistance corresponds to cultivation 1: 8000-1: 14 000 (on the average 1: 12 000), oligozoospermii to I degree - 1: 6000-1: 12 000 (on the average 1: 10 000), oligozoospermii to II degree - 1: 500-1: 4000 (on the average I: 2000), oligozoospermii III degrees - 1: 500-1: 2000 (on the average 1: 1000).

Test on intensity of oxidation-reduction processes in spermatozoonah. The preference is deserved by method N. P.Shergina, according to whom at normozoospermii oxidation-reduction processes (decolouration metilenovogo dark blue) proceed on the average 47 mines (from 23 to 75 mines), at oligozoospermii: I degrees-71 of mines (from 50 to 150 mines),

II degrees-127 of mines (from 75 to 250 mines), III degrees - 202 mines (from 75 to 360 mines).

The Named two tests for resistance and activity definition

Oxidation-reduction processes essentially supplement in doubtful cases the characteristic ejakuljata.
