Test on compatibility and penetratsionnuju ability spermatozoonov. If the done researches do not establish the barreness reason at full health of both spouses it is expedient to spend one of biological tests on compatibility and penetratsionnuju activity spermatozoonov.

There are two most simple tests: Shuvarsky and Kurtsroka - Miller.

Test Shuvarsky. It is made during the period ovuljatsii. To the woman through 2-3 ch after sexual intercourse enter into a vagina nothing the greased mirror and aspirirujut a syringe vagina contents, and then slime from the channel of a neck of a uterus. Drops of the first and second contents are located on the different ends of subject glass and become covered by integumentary glasses. In the presence of enough actively mobile spermatozoonov in both drops test is considered positive and testifies to full compatibility spermatozoonov and secrets of female genitals.

If spermatozoony are defined in enough, but they are motionless, it is necessary to establish the reason of their immovability. For this purpose it is necessary to investigate ejakuljat and to define degree of cleanliness of a vagina, and also its kislotno-core a condition.

Presence at a vagina of enough mobile spermatozoonov and their absence in cervical slime or definition of only individual copies testifies to an obstacle between a vagina and a uterus (endotservitsit, a resistant cervical mucous stopper, etc.)

In such supervision the great value has correctness of a choice of term of research. The mucous membrane of a neck of a uterus only during the period ovuljatsii gets property to produce a secret optimum for ability to live and penetration spermatozoonov in a cavity of a uterus. During other time, i.e. Out of the period ovuljatsii, the secret of the channel of a neck of a uterus of the healthy, capable woman to conception is often impenetrable for spermatozoonov.

At doubtful results of the previous test for) estimations of permeability of cervical slime for spermatozoonov test Kurtsroka-Millera is spent.

Test Kurtsrok a-m and l l e r and. Test carry out during the period ovuljatsii. The woman brings a test tube with ejakuljatom the spouse not later than through 1 ch after its reception. On subject glass it is put (before contact) a drop of cervical slime and a drop ejakuljata. The preparation can be investigated without integumentary glass. Under the big increase in a microscope the border between drops is clearly allocated. Spermatozoony accumulate at border with a slime drop. Test schi-. It is thawed positive if through 1 ch the most part spermatozoonov gets into cervical slime, keeping active progress.

In doubtful cases it is possible to spend a recross nuju test: carry out research of cervical slime of the healthy woman with sperm of the examinee of the man and on the contrary - ejakuljata the healthy man cervical slime of the woman of a fruitless married couple.
