News | New Male Contraceptive Takes Effect Within 30 Minutes, With Fertility Returning the Next Day
Study: On-demand, nonhormonal male contraceptive could change family planning
According to a study published in Nature Communications, scientists have identified an oral, on-demand male contraceptive based on a soluble adenylyl cyclase (sAC) inhibitor. The contraceptive was nontoxic in the study and does not require continuous use. A single oral dose temporarily prevented male fertility within 30 minutes, with normal fertility returning the next day, potentially offering a new option for male contraception.
Background: Addressing the Limited Options for Male Contraception
Male contraceptive options are currently limited to condoms and vasectomy, both of which have limitations. An estimated 50% of pregnancies worldwide are unintended, underscoring the need for more convenient and effective male contraceptive methods.
The study’s primary goal was to identify an effective and reversible method that avoids the side effects of hormonal contraceptives. Scientists previously tested several hormonal and nonhormonal approaches, such as interrupting sperm production or suppressing sperm motility. These methods often take months to work, and fertility may take months to return after discontinuation.
Breakthrough Discovery of an sAC Inhibitor
Researchers focused on soluble adenylyl cyclase (sAC), a key enzyme involved in sperm motility. They found that blocking sAC could effectively suppress sperm activity and prevent sperm from fertilizing an egg.
The scientists developed an sAC inhibitor called TDI-11861. The compound is taken orally, is highly effective at low doses, and remains active in inhibitor-free environments such as the vagina. A single dose of TDI-11861 rapidly and significantly suppressed sperm motility in mice without adverse effects on the testes, epididymides, or overall health.
Clinical Significance and Future Outlook
Unlike conventional contraceptive medications, TDI-11861 does not require continuous use. The study found that it took effect within 30 minutes and fertility returned 24 hours after use. This may reduce the risk of side effects from long-term medication and offer men a more flexible family-planning option.
Although the current research was conducted in mice, the researchers are optimistic that future clinical trials could evaluate the safety and effectiveness of this approach in humans. If successful, this on-demand contraceptive could substantially change male contraception and family planning worldwide.
