The regulation of male reproductive function today is not limited to surgical castration; there are many other methods of controlling reproductive function. Non-surgical methods of controlling male reproductive function can be reversible and not reversible, i.e., reproductive function is preserved or completely suppressed. Castration of males or orchiectomy leads to irreversible sterility of the male, when the male completely loses the ability to reproduce. This operation can also entail some side effects: obesity, underdevelopment of the external genital organs, an increased risk of diabetes or hypothyroidism, problems with frequent urination and behavioral problems. Therefore, methods of non-surgical management of reproductive function and contraception in males are being actively developed. The article presents the latest methods of contraception and the management of the reproductive function of male domestic animals (cats, dogs): clinical application GnRH and agonists GnRH, Non-Peptide GnRH Antagonists, GnRH-Toxin Conjugate, GnRH Vaccines and other immune contraceptive vaccines, chemical sterilants for intratesticular injections, calcium chloride, zinc gluconate, chlorhexidine digluconate, hypertonic saline, sex steroids (progestines), gene silencing, kisspeptin and GnIH, targeting delivery of cytotoxins, single-dose hormonal male and female sterilianr, FSH – receptor ligand cytotoxin conjugates, Sperm Protein Reactive with Antisperm Antibodies (SPRASA) Reversible Inhibition of Sperm under Guidance(RISUG).
