There are other means besides hormonal ones. One of the methods currently being tested uses some kind of gel to block the vas deferens, the ducts that transport sperm away from the testicles. It’s reversible too. And then there are temperature based methods. I’ll add, to answer another poster, that condoms are really not a great method of contraception, because it relies so much on good practices on the user part every time you have sex. Were I a woman, I wouldn’t trust a condom and use a another form of contraception anyway, though obviously it has other benefits, notably protecting from STIs. Personnally, I will certainly use male contraceptives once they become available. There’s no reason this burden should rest on women’s shoulders alone. Altough again, were I a woman, I’d need to really trust the man i’m having sex with before relying solely on his contraception to do the job, considering that i’d be the pregnant one if things go wrong.
