Yes they do, in fact spermicides used together with latex condoms are quite effective.
condoms.
You haven't described the configuration of your experiment, but there's enough suggested to convince me that I don't even want to try to visualize it.

Well latex condoms are good to prevent pregnancy for the most part but as opposed to latex or polyurethane condoms or animal skin condoms are all good but I recommend spermicidal lubricated condoms.
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.
There are several birth control methods out there. However, the only 100% effective method is abstainance, as condoms can have holes in them, he might not pull out in time, and pills don't always work.
Condoms and foam are non-prescription methods. Dipahragms are by prescription. All of these methods are barrier methods.
sure in fact, some condoms have spermicidal lube if i were you id cut out the middleman and just buy those
Sure it works. Most of the time.
Because a lubricant (makes things slippery) so a condom may be lubricated but not kill sperm (spermicide) BUT all spermicidal condoms are also lubricated.
A study showed that it could have spermicidal effects... However you shouldn't rely in this if you don't want to get pregnant. Go on the pill, use condoms...
Apart from abstention they are the best protection against STDs. There are other alternatives for contraception such as spermicidal gels, IUDs, oral pills, sterilisation etc.
100% if you had sex a black man, then it's a 100% chance the he leaves you with the kid and never sends in child support
Spermicidal lubricant doesn't protect against STDS like HIV or gonorrhea, first of all. Spermical lube makes things slippery and kills 90% of sperm.
yes, you can get pregnant any time there isn't any 100% way not unless you get your tubes tied or have a hysterectomy. also, condoms are more likely to tear if you use more than one at a time...
