Espermicidas
¿Qué es espermicida?
“Spermicide” describes a bunch of different creams, films, foams, gels, and suppositories that you insert deep into your 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 your cervix and into your uterus. (Think of your cervix like a doorway between your vagina and your uterus.) In order for spermicide to work correctly, you have to insert it deep into your vagina, so that it actually covers your 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.

Types of spermicide
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 you’re 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.
Prescription spermicide (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 your vagina, which interferes with how sperm move. Phexxi is more effective when used on its own than over-the-counter spermicides are when they’re used on their own. Phexxi can also be used with any other method of birth control (except the ring) for extra pregnancy prevention.
