Once you have a steady, trustworthy partner, condoms are mostly used just to prevent pregnancy.

So a cheap and easily reversible vasectomy wouldn't eliminate the condom market, but it would certainly disrupt it I would think.

I would assume they're focused on STIs, HIV and AIDS rather than decreasing pregnancy rates. Whilst vasectomy reversal would disrupt condoms, male anti-birth pills (getting ever closer to production) are more likely to achieve what you're thinking.

Agreed, but I think the main reason for people using condoms is to reduce pregnancy. The STD prevention is just a value-add (or at least that's what the Neurosyphilis voices in my head are telling me)

I think that was a joke
