With the rise of unwanted pregnancies, single-parenthood, and divorce, many pharmaceutical companies continue to devise more effective and affordable methods of birth control. It is a way for men and women to prevent pregnancy. There are many methods of preventing pregnancy; some are natural while others may include the use of synthetic materials.

Spermicides are considered as among the best methods of birth control. It comes in various forms: foams, gels. tablets. creams, suppositories, or dissolvable films that can be used by women. Spermicides contain chemicals that destroy the sperm and prevent it from fertilizing an egg. The active component of many sperimicides is a chemical called nonoxynol-9 (N-9).

Spermicides can be used alone but are more effective when combined with other family planning methods like condoms, diaphrams, or cervical caps. Spermicides combined with condoms are about 97 percent effective in preventing pregnancy. A dose of spermicide may be effective for about an hour. Afterward, the spermicide and the semen may trickle out of the vagina for some time. It is advisable for individuals who use this kind of method to wait at least six hours before rinsing or douching. This would allow the active ingredients of the product to eliminate the sperm.

Here are other precautions that should be remembered while using spermicides:

Wash hands before using or inserting the spermicide to reduce the chances of vaginal irritaion and urinary tract infections.
Store the spermicide in a convenient location in a clean area or storage at room temperature.
If a spermicide inserter (applicator) has been used with the foam, gel or, in some instances, insert, wash it after each use, with plain soap and warm water, and shake the excess water from the applicator. Do not use talcum powder on the inserters.
A panty shield may be used after intercourse if leakage of spermicide and ejaculate is bothersome.
The spermicide may have a medicinal taste. Therefore, if oral sex on the woman is part of your sexual play, you may want to insert

the spermicide after this occurs.

Despite its effectiveness, spermicide use may bring unwanted side effects. It may cause irritation and induce itchiness and rash around the vagina and surrounding areas. This happems when the chemicals that kill the sperm dissolve the other outer membranes. In addition to these side effects, chemicals in some spermicides may eliminate beneficial bacteria in the vagina and disrupt the body's balance of normal bacteria, making it more prone to micro-organisms that may cause urinary tract infection (UTI). These side effects are mild and may disappear after stopping spermicide use.

Individuals who want to use this kind method should consult doctors and follow the instructions on the product label to reduce the development side effects. Men and women who develop allergies after using spermicides should refrain from using it. If used properly and cautiously, spermicides are a relatively safe and effective family planning method.
