Regarding this, how effective is spermicide?
Although you can use spermicide alone, it works better when you combine it with a condom or diaphragm. Spermicide used alone is about 70% to 80% effective, but when used together and properly, spermicide and condoms are about 97% effective in preventing pregnancy.
Beside above, which spermicide is most effective? The most effective strength spermicide contains at least 100 mg of nonoxynol-9 per dose. You are more likely to get pregnant if you use a weaker spermicide. There is no difference in effectiveness between various spermicide types, such as gel, film, or suppository.
Then, how do you get spermicide?
Spermicide is sold over-the-counter online and at pharmacies, drugstores, and some supermarkets and grocery stores. You can also find spermicides at some family planning clinics and Planned Parenthood health centers. You don't need a prescription and there are no age restrictions — anybody can buy spermicide.
Does spermicide kill a fertilized egg?
The spermicide is put deeply inside the vagina and works to prevent pregnancy by stopping and killing sperm before they can reach an egg and fertilize it.
