How it works

A reusable silicone dome covers the cervix to block sperm from entering the uterus. Used with spermicide for added effectiveness.

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