Title Size dependent inhibition of sperm motility by copper particles as a path towards reversible male contraception

Abstract Effective inhibition of sperm motility using a spermicide can be a promising approach in developing non-invasive male contraceptive agents. Copper is known to have contraceptive properties and has been used clinically for decades as intrauterine contraceptive devices (IUDs) for contraception in females. Beyond that, the spermicidal use of copper has not been explored much further, even though its use could also subdue the harmful effects caused by the hormonal contraceptive agents on the environment. Herein, we study the size, concentration and time dependent in vitro inhibition of bovine spermatozoa by copper microparticles. The effectivity in inhibiting the sperm motility is correlated to the amount of Cu2+ ions released by the particles during incubation. The copper particles cause direct suppression of sperm cell motility upon incubation and thereby show potential as sperm inhibiting, hormone free candidate for male contraception beyond condoms.
