NOTHING is 100% effective and you always run the risk of getting pregnant. The only Birth Control is the pill or patch and there are a lot of long-term side effects from this. This problem has always been a blight to women and scientists would come up with more options for birth control for men only they'd forget to take it. LOL
some do some don't. read the box
Trojan brand condoms are the most reliable. Use their spermicidal lubricant types for increased protection.
Yes they do, in fact spermicides used together with latex condoms are quite effective.
Properly used they are very effective. BUT no birth control is 100% effective.
Spermicidal condoms kill sperm.

In the US, spermicidal foam is available without a prescription. It is not a very effective contraceptive on its own, but is effective when used with condoms or other forms of contraception.
Because a lubricant (makes things slippery) so a condom may be lubricated but not kill sperm (spermicide) BUT all spermicidal condoms are also lubricated.

Spermicidal condoms are very effective providing they do not rip or tear..1 percent according to condom labels. Condoms are 99.9 percent effective. Word of advice from a single mom though, go get birth control and always use a condom. Better to be super safe, than not.
The latex or material they are made of can wear down, and become less effective, and expire. Also, if they are spermicidal, the spermicide can expire as well.
Some are and some aren't but if the package doesn't say spermicidal lubricant, assume it's not and get your own. It's over the counter in most drugstores in the U.S.
