23 Million Women in the U.S. Aren't Using Hormonal Birth Control

They're not opting out of protection — they're opting out of side effects. Depression. Mood swings. Weight changes. Blood clot risks. For too long, the only "choice" was between hormones you didn't want or no FDA-approved alternative at all.

The First Hormone-Free Prescription
Birth Control Gel

PHEXX works by maintaining your vagina's naturally acidic pH (3.5–4.5). When semen enters, it raises pH, allowing sperm to swim. PHEXX keeps pH in the baseline range, lowering sperm mobility and reducing the chance of fertilization. Science, not hormones.
