Spermicidal
Spermicidal
Spermicidal (pronunciation: /spɜːrˈmaɪsɪdəl/) refers to substances that are used to kill sperm or make them inactive. The term is derived from the Latin words "sperma" meaning seed and "caedere" meaning to kill.
Usage
Spermicidal agents are commonly used in conjunction with other forms of birth control methods such as condoms or diaphragms. They come in various forms including creams, foams, films, or suppositories.
Mechanism of Action
Spermicides work by damaging the sperm cell membrane, thereby reducing their mobility and preventing them from joining with an ovum. The active ingredient in most spermicides is nonoxynol-9.
Effectiveness
The effectiveness of spermicides as a sole method of contraception is lower than when used in combination with other methods. They are more effective when used correctly and consistently.
Side Effects
Some people may experience irritation or allergic reactions to spermicides. Frequent use of spermicides containing nonoxynol-9 may increase the risk of HIV transmission.
