Does male birth control exist?

Yes as @srmorgan says, condoms are a wonderful option. Just don’t eat too many of them at once.

I think there are chemicals or hormones that can lower sperm production. Estrogen might lower it—not sure about that. There are physical methods, too. Besides condoms you can get a vasectomy. Or you could get lucky and be born without a vas deferens.

Anyway, I think men aren’t into hormone treatments, usually. But they don’t have to carry the babies. Usually, if they don’t ever want any more children, they’ll get vasectomies. If they only want a temporary (and breakable) barrier between sperm and egg, they’ll use condoms. Of course, if they want to be safer from STDs, they’ll wear a condom anyway, even if they had no sperm at all.
