There are oral contraceptives for men, but most of them are more hormonal interference in the body, in addition, there is a possibility of irreversible spermatogenic damage, so be careful or think carefully before using, the specific types of drugs are as follows: First, androgens, androgens alone can be used as a male antifertility method, because a certain blood concentration of androgens can inhibit the pituitary gonadotropins and reduce androgen production, synthesis, and release in the testes, resulting in impaired spermatogenesis. Generation, synthesis and release of androgens in the testes, resulting in impaired spermatogenesis, such as oral administration of high doses of testosterone undecanoate. Second, cotton phenol, cotton phenol can inhibit spermatogenesis, so that the number of spermatozoa greatly reduced, but also can inhibit spermatozoa movement, specific effect on the mitochondria of spermatozoa, and inhibit the flagellum of the power of the protein, that is, the activity of ATPase. Thirdly, the extract of Radix Rehmanniae, which can cause reversible sterility in male animals, contains the extracts of diene Radix Rehmanniae lactone enzyme, Radix Rehmanniae hydroxylactone, and its isomers, all of which can be used as contraceptive drugs. Ranunculus can act on the testes and spermatozoa, and the target cells are mainly spermatogonia and spermatocytes, and eventually spermatogonia can also be involved.
