Will Spermicide Kill Sperm?

Spermicide is a type of contraceptive that kills sperm or stops it from moving. You insert spermicide in the vagina before sex. The chemicals in the spermicide, such as nonoxynol-9, prevent sperm from entering the uterus. You can get spermicide over-the-counter.

How long does it take spermicide to kill sperm?

Some spermicide products require the couple to wait 10 minutes or more after insertion before sex. One dose of spermicide usually lasts 1 hour. For repeated sex, use additional spermicide. After sex, the spermicide has to remain in place for 6-8 hours to make sure the sperm are killed.

Can sperm survive spermicide?

Spermicides don't kill sperm. Instead, they stop the semen from moving, which decreases sperm motility. The woman applies it near her cervix so the sperm can't enter into the uterus. When you use spermicide correctly and consistently along with male condoms, it's 98 percent effective.
