Spermicidal is a chemical called nonoxynol-9 comes in many forms and can destroy sperm on contact. Spermicides are composed of a spermicidal agent in a carrier that allows dispersion and retention of the agent in the vagina. Spermicidal contraceptives are useful additional safeguards but do not give adequate protection if used alone except where fertility is already significantly diminished. They are suitable for use with barrier methods such as the cap and diaphragm.
There are several different types of spermicides. Most are similar in terms of cost and how well they work. Put the spermicide in before every act of sex. Always read the directions that come with every spermicide. If you have sex again, insert more spermicide. Do not douche for at least 6 hours after intercourse, or you could wash away the protection. They come as jellies, creams, suppositories and foam.
Avoid spermicides in men and women who might be at high risk of infection, as multiple use of spermicide may cause irritation to the vagina and rectum, increasing the chance of infection.
Spermicides are available as:
Aerosol foam Cream1 Film Jelly Pessary Sponge
