How effective are spermicidal lubricants on condoms?

They increase the protection by about 5 % I think and the box even tells you that the condoms with spermicidal lubricant are not to be used in place of a vaginal spermicide in combination with a condom the spermicidal lubricant is just there to add a little more insurance in case the condom breaks but as you know many people still do get pregnant so use a more reliable form of birth control in combination with the condom....hope this helps Good Luck and God Bless!!

SPERMICIDAL CONDOMS

IF THE condom has nonoxynol-9 as a spermicidal lube, nonoxyl-9 does prevent pregnancies and also kills the AIDS virus. However, I don't know HOW MUCH is actually present on the condom, so a good precaution would be to use a nonoxyl-9 suppository such as "ENCARE" in ADDITION to the condom. Encare is sold where condoms and lubricants are sold. Better safe than sorry!

Answer

I have never heard of nonoxynol 9 killing the HIV virus there is no scientific evidence of this....

--Check out the website MedScape.com and search nonoxynol-9. There is a great deal of info there. MedScape Select links the search to 170 of the most clinically relevent journals for physicians. Thanks.

Nonoxynol-9 can actually irritate cells prone to HIV and its common to have allergic reactions when using spermicides containing it.
