How it works

Surgical disruption (clipping, banding, cauterization, or complete removal) of the fallopian tubes prevents eggs from reaching the uterus and sperm from reaching the egg.

Track basal body temperature, cervical mucus, and cycle length to identify the fertile window. Avoid unprotected sex or use backup contraception on fertile days.
