Non-hormonal male contraceptive implant lasts at least two years in trials.

An implantable, non-hormonal male contraceptive has been shown in trials to last for at least two years. The contraceptive, known as Adam, is a water-soluble hydrogel that is implanted in the sperm ducts, preventing sperm from mixing with semen.

Early results are very promising: two participants achieved zero sperm count at 24 months with no serious side effects. If successful, this simple injection could provide men a reversible, long-lasting birth control option, offering a strong alternative.

With increasing demand for male contraceptive solutions, particularly after legal changes like the overturning of Roe v. Wade, this innovation could reshape the future of family planning, giving men more direct control over reproduction.
