Contraception for males

Vasectomy is an elective surgical procedure that results in male sterilization, often as a means of permanent contraception. During the procedure, the vasa deferentia are cut and tied or sealed so as to prevent sperm from entering into the urethra and thereby prevent fertilization of ova through sexual intercourse. Vasectomies are usually performed in a physician's office, medical clinic, or, when performed on a non-human animal, in a veterinary clinic. Hospitalization is not normally required as the procedure is not complicated, the incisions are small, and the necessary equipment routine.

Gossypol () is a natural phenol derived from the cotton plant (genus Gossypium). Gossypol is a phenolic aldehyde that permeates cells and acts as an inhibitor for several dehydrogenase enzymes. It is a yellow pigment. The structure exhibits atropisomerism, with the two enantiomers having different biochemical properties.

Desogestrel is a progestin medication which is used in birth control pills. It is also used in the treatment of menopausal symptoms in women. The medication is available and used alone or in combination with an estrogen. It is taken by mouth.

YCT529 is an experimental non-hormonal male contraceptive developed by YourChoice Therapeutics. It functions as a selective antagonist of the retinoic acid receptor alpha (RAR-α), a nuclear receptor involved in vitamin A signaling. By inhibiting RAR-α, YCT529 disrupts spermatogenesis, leading to temporary infertility. YCT529 targets RAR-α, which plays a crucial role in the vitamin A signaling pathway essential for sperm production. By selectively inhibiting RAR-α, the drug impedes the development and maturation of sperm cells without affecting other physiological processes governed by vitamin

JQ1 is a thienotriazolodiazepine and a potent inhibitor of the BET family of bromodomain proteins which include BRD2, BRD3, BRD4, and the testis-specific protein BRDT in mammals. BET inhibitors structurally similar to JQ1 are being tested in clinical trials for a variety of cancers including NUT midline carcinoma. It was developed by the James Bradner laboratory at Brigham and Women's Hospital and named after chemist Jun Qi. The chemical structure was inspired by patent of similar BET inhibitors by Mitsubishi Tanabe Pharma. Structurally it is related to benzodiazepines. While widely used in la

Gamendazole is a drug candidate for male contraception. It is an indazole carboxylic acid derived from lonidamine (LND). It has been shown to reduce fertility in male rats without affecting testosterone levels, but human clinical trials have not been started.
