What is spermicidal lubricant designed for?
Some condoms contain the spermicide nonoxynol-9 (N-9). N-9 has been proven to kill sperm and/or reduce its motility. N-9 is an important backup to help reduce the risk of pregnancy in case a condom is not used properly during vaginal intercourse and erection is lost before withdrawal and some semen spills outside the condom. N-9 does not provide any protection against HIV/AIDS or other STDs; it is a spermicide only. Also, spermicidal lubricants are not for rectal use or more than once a day vaginal use. Nonoxynol-9 may be irritating to some people, especially with use more than once a day, and vaginal irritation can increase the risk of STDs or AIDS.
