Spermicide and gel
Overview
“Spermicide” describes a bunch of different creams, films, foams, gels, and suppositories that are inserted deep into a woman’s vagina before sex to prevent pregnancy. On its own, spermicide provides some pregnancy prevention, but pairing it with another method is way more effective. Some condoms come coated in spermicide, or you can use a separate spermicide along with a condom. There are other methods, like the cervical cap and the diaphragm, that need to be used with spermicide to be effective.
Spermicide contains chemicals that prevent pregnancy in two ways. The first way spermicide works is by stopping sperm from moving normally. The second way is by keeping sperm from getting through the cervix and into the uterus. In order for spermicide to work correctly, it has to be inserted deep into the vagina, so that it actually covers the cervix.
Phexxi is a birth control gel that is similar to over-the-counter spermicide but is more effective. Phexxi is only available by prescription.
Quick Facts
Pretty effective if used correctly. Can be put in up to an hour before sex and doesn’t affect hormones.
Effectiveness
Spermicide on its own, without a barrier method like a diaphragm or condom, is pretty effective the way most people use it. Prescription-only vaginal gel is more effective than over-the-counter spermicide.

Types of spermicide and gel - Prescription vaginal gel (Phexxi)
Phexxi is similar to spermicide in that it’s a gel that goes into the vagina before sex to prevent pregnancy. It works by maintaining the low pH of the vagina, which interferes with how sperm move. Phexxi is more effective when used on its own than over-the-counter spermicide is when it’s used on its own. Phexxi can also be used with any other method of birth control (except the ring) for extra pregnancy prevention.
Types of spermicide and gel - Over-the-counter spermicide
Most spermicides are sold over the counter, which means you don’t need a prescription to get them. Over-the-counter spermicides contain a chemical called nonoxynol-9. They come in different forms—they can be gels, films, foams, suppositories, or creams. Popular over-the-counter spermicide brands include VCF and Options Gynol II.
If someone is a diaphragm or cervical cap user, using spermicide as well is key to effective pregnancy prevention. On its own, over-the-counter spermicide does offer some pregnancy prevention, but using it with another method is much more effective.
