Scientists developed contraceptive for men

American and Italian scientists developed the contraceptive means for the men, which stops the process of the formation of sperm.

Tests on the rats showed that new preparation they block connection with the cells, which feed spermatozoids.

Researchers say that they used relatively low doses of substance and found no obvious side effects. To now by scientist it is necessary verify preparation on the people in order to ascertain that it is effective and safe for the men.

In the seed channels, where sperm is formed, Sertoli's cells, which feed spermatozoids, are located. If connection with these cells is blocked, this can lead to the man sterility. The molecule, on basis of which is created new preparation, displaces the developing sperm from Sertoli's cells.

The method of protection without the application of hormones, which directly influences spermotogenez (process of the formation of spermatozoids), considers it very attractive, since it does not influence the work of man sexual gland.
