Contraception without the side effects of pills, devices, or implants. Yaso is testing a unique, multipurpose drug platform in a Phase 1 clinical trial. Our mission is to enhance family planning and health, globally.

Our patented drug, PPCM, shows broad activity against viral and bacterial pathogens, with the potential to prevent and treat drug-resistant strains. That’s important for stopping the spread of STDs, worldwide.

Strong futures start with smart planning. But 257 million women worldwide lack family planning options. 30-35% of women using hormonal birth control report side effects. Among those who discontinued oral contraceptives, a survey found that 64.6% did so because of adverse effects. Yaso offers a new promising non-hormonal contraceptive that is pleasant, effective, safe, and affordable. We are launching a new era of contraception — safe, simple, and accessible.
