Birth Control Patch
A progesterone birth control patch is a skin patch that delivers a steady dose of synthetic progesterone (progestin) into the bloodstream to help prevent pregnancy. It works by thickening cervical mucus to block sperm, thinning the uterine lining to prevent implantation, and sometimes stopping ovulation. Unlike combined hormone patches that contain both estrogen and progestin, a progestin-only patch may be suitable for individuals who cannot use estrogen due to health risks. The patch is typically worn on the skin and replaced on a regular schedule—often weekly. Researchers are currently studying new versions of progesterone-only patches to expand birth control options for more people.
