Been following this for years, even donated to it a couple times. Just annoyed that it's been so long in coming. If I had the money, I'd probably have flown to India for this a while ago. This is a reversible birth control for males with few if any side effects. All you needle-phobes: the actual procedure will take a few minutes when done by a trained practitioner. A few minutes for something that'll likely last you 10 years or more. Sack up.
I've looked extensively through the options available to women and they are appalling. I would never expect a woman to put herself on a hormonal birth control that I would never consent to myself. Even the copper IUD has some major potential problems if the woman contracts an STI. I look forward to being able to take responsibility for birth control. And I'll happily use a condom on top, too.
Edit: regarding cost, I've read estimates that it would cost $15 per person before. It'll be cheap.
