| How it works | A small silicone cap fits snugly over the cervix and stays in place by suction, blocking sperm from entering the uterus. Used with spermicide inside the cap. | The man withdraws his penis from the vagina before ejaculation to keep semen out of the vagina. Pre-ejaculate may contain some sperm, which is why perfect use is not 100%. A 2024 pilot study found sperm in about 13% of pre-ejaculate samples, though roughly 75% of participants had no sperm in any sample. |
