A revolutionary breakthrough in reproductive health is giving men a safe and reversible alternative to traditional birth control methods. This innovation could transform the way couples share responsibility for contraception.
Biotech company Contraline, based in the U.S., has developed a device known as Adam—a male contraceptive that works with just a single injection and lasts for up to two years. Early Phase I clinical trials have shown promising results, according to reports from The Guardian.
Unlike condoms or surgical procedures like vasectomy, Adam takes a different approach. Doctors inject a water-based hydrogel into the vas deferens—the tube that carries sperm from the testes. Once in place, the hydrogel forms a physical barrier that prevents sperm from leaving the body during ejaculation.
Researchers describe the material as “soft and jelly-like,” with a composition that’s primarily water. Importantly, the sperm that gets blocked doesn’t cause harm; instead, the body naturally reabsorbs it. Men still produce semen, but without sperm present, pregnancy is prevented effectively and safely.
If future trials confirm these early results, this injection could become one of the most significant advancements in male birth control in decades, giving couples more freedom and flexibility in family planning.
