Nonoxinol 9How does it work?Nonoxinol 9 is a chemical that is used in conjunction with other contraceptive barrier devices。 It is a spermicide (kills sperm)。 Nonoxinol 9 disrupts the sperm cell membrane, causing the contents of the cells to leak out。 This affects the motility of the sperm and ultimately leads to their death。 Nonoxinol 9 does not provide adequate birth control if used alone。 It is only effective when used with barrier methods such as condoms, diaphragms or caps。 It is used for additional protection against the risk of becoming pregnant。 It is available in the form of pessaries, creams, gels and foam。。
