Nonoxynol-9 is a vaginal spermicide used for the non-hormonal contraception in conjunction with other modes of contraception.
Nonoxynol-9 interacts with the lipids in the membranes of the acrosome and the midpiece of the sperm. The sperm membranes are lysed; the acrosome, neck and midpiece of the spermatozoa are loosened and then detached which results in their immobilization and death.
