In the female sexual products of animals they are revealed: 1) ginogamon I, which amplifies i prolonging the mobility of spermatozoids; the antagonist of androgamone I; the low-molecular thermostable substance of nonprotein nature. 2) Ginogamon II (fertilizin), which causes the agglutination of spermatozoids. According to Lilli, it is the necessary component in connecting spermatozoid with the egg, however, according to contemporary data, its function consists in the elimination it means, the parts of the spermatozoids, that are approached an egg. In the sea urchins of fertilizin it is identical to the material of jelly-like shell and is glycoprotein; substance analogous in its action are had inside the egg the sea urchins (tsitofertilizin) and the bony fishes. 3) the substance, which inactivates the agglutinating beginning (antifertilizin to yaytsa);u of sea urchins precipitates the gel of jelly-like shell and is caused the agglutination of eggs; the antagonist of ginogamona II; protein.

In the man sexual products of animals they are found: 1) androgamone I, which suppresses the mobility of spermatozoids; the antagonist of ginogamona I; the low-molecular thermostable substance of nonprotein nature. 2) androgamone THE II (antifertilizin of spermatozoid), which inactivates agglutinating beginning; on the action it is similar antifertilizi- Nome egg; relatively thermostable protein. 3) androgamone III, which causes the dilution of the cortical layer of egg; low-molecular thermostable connection (in sea urchins, apparently, the unsaturated fatty acid). 4) the lysine of spermatozoid, which dissolve facial shells; thermolabile proteins (in mammals - ferment hyaluronidase).
