Spermicides obstruct the cervix (the opening to the uterus) and slow down sperm, making it more difficult for them to swim to an egg. To be effective, the spermicide must be inserted deep in the vagina near the cervix.
Spermicidal Condom
Condoms impregnated with spermicide can improve pregnancy prevention while also protecting against Sexually transmitted infections.
Spermicidal Jellies
Jelly is frequently used as a lubricant with diaphragms or cervical caps. It also provides an extra layer of protection if sperm manages to cross through a diaphragm or cervical cap barrier.
Contraceptive Cream
This gel is inserted similarly to the jelly as an alternative lubricant. Place the applicator as close to the cervix as possible and use the plunger to push the gel out.
Contraceptive Sponge
Contraceptive sponges are placed into the vagina and are made of soft foam with spermicide added.They take effect immediately and provide up to 24 hours of protection.
There are numerous spermicide brands and varieties available, but they all function in the same way. They block the cervix and prevent sperm from migrating.
