Typically, ''spermicide'' is a misnomer ; it's just a gel, cream, foam or plug shoved all the way down the vagina to block the sperm from swimming deeper into the reproductive tract to fertilize an egg.
On a hunch, I was curious if copper or silver can fuck with (murder) sperm like it can with pathogenic cells. Supposedly that's actually how the copper IUD contraceptive works. Somehow I never realized that connection until just now.
Doubt there'd be a viable way for that to work from the guy's end though, since copper's effects on cells usually requires at least a few minutes to a few hours of contact, which makes it far more viable at "repelling" sperm from the uterus than murdering it outright during transmission.
Sperm can occasionally survive, viably, in a variety of environments for a fair amount of time (basically, think of how long viruses can sometimes last out outside the human body).
And all it takes is for one successful little swimmer to make it to the goal.
Sperm remains viable during anywhere from several hours to 5 days in a warm and wet environment.
How long does the spermicide take to work?
Assume it dosen't work.

It's also not very effective.
