A reader writes:
I'm far past the age when this procedure would interest me, but I do know that if a potential partner told me I didn't need to worry – he'd been RISUG'd – I'd just laugh and get out my diaphragm. That's the problem with male contraception: if a woman can't see proof, she's a fool to take a chance.
Because she is ultimately the one dealing with an unintended pregnancy. But another reader points to a risk unique to men:
Your reader wrote, "But the more I think about it, the more I'm reminded that male culture ultimately says that the junk is untouchable, and that any modification or interference is somehow emasculating or 'too risky' for the family jewels." Yes, men are babies in a lot of respects. But there's an important difference between men and women when it comes to "junk". Surgical procedures on either can lead to risks in future fertility, but with men there is a risk of future impotence as well. Unless I'm mistaken, women aren't going to lose the ability to orgasm if something goes wrong with their fallopian tubes. But men can lose that ability if something goes wrong with their "junk".
