The WHO no longer promotes the use of spermicidal condoms, and for good reason. They have a shorter shelf life than normal condoms, they've been linked to UTIs, and if you're already using a condom, they really don't reduce your pregnancy risk much. In addition, if you're allergic to them like I am, they can cause some serious burning and/or itching after use.
If you want to use condoms, I would recommend getting lubricated ones without spermicide. Of course, if it's a condom with spermicide or no condom at all, it's still better to go with a spermicidal condom.
