you are: DIAGNOSTICS

Hynie (1964) has developed the simple test, consisting that time in seconds is registered, during which 100 spermatozoonov both parallel parties of a small square schetnoj cross Volume chambers, then is calculated so-called propulsionnyj an indicator, for what 60 () divide into time (in seconds), spent for crossing of lines of a square 100 spermatozoona. Results propulsionnogo an index from 0,6 to 2 are characteristic for rather prolific sperm, 0,6-0,2 - less prolific, 0,2 and less - unfruitful. As fruitfulness of sperm depends on many indicators, its definition represents the decision of a problem with many unknown persons. The indexes named above do not cover all features of sperm which in aggregate cause impregnating ability. For example, pathological forms, the kislotno-core a condition, time razzhizhenija, autoimmunnye changes, quantity of fructose and so forth are not considered Searches of more successful integrativnyh estimation formulas ejakuljata proceed. At the Tbilisi institute generativnoj functions of the person in andrology laboratory, rukovodimoj T. V.Begiashvili, is offered a technique of an estimation of fruitfulness of sperm (R.B.Kapanadze, 1977) in which four indicators are taken for a basis: quantity spermatozoonov in 1 ml, percent spermatozoonov with rectilinear movement, percent of motionless and pathological forms. Each indicator is subdivided into three gradation on mark calculation.

The Quantity spermatozoonov in 1 ml is estimated as follows: 400 million - 0; 40-60 million - 7; 60 million - 10; progress (in percentage): 60-0; 60-70-3; 70-7; motionless (in percentage; 15-7, from 15 to 30-2, 30-0; pathological forms (in percentage): 20-16; 20 25-7; 25-0. The Average index 26,6 - high fruitfulness of sperm; 20,8 (fluctuations from 21 to 12) the-lowered fruitfulness; 3,3 (from 12 to 0)-weak fruitfulness of sperm.

Considering, that fruitfulness of sperm depends on many other things indicators, the author perfectly supplements the named scheme with data about degree spermatoagglju-tinatsii, fatigues spermatozoonov and resistance spermatozoonov to cultivation of sperm of 1% a solution of sodium of chloride 1: 100, 1: 200, 1: 800, 1: 1600. Last additions favourably distinguish R.B.Kapanadze's scheme from other schemes of an estimation of fruitfulness ejakuljata.

Fruitfulness Indicators make variety of the characteristics reflecting biological properties spermatozoonov, features of plasma of sperm, and also the external and internal factors influencing fruitfulness.
