I am always surprised that every discussion of vasectomy, and even this solution, hand-waves away the experience one undergoes in the process. Before doing this yourself, at least know what your getting into:
For example, compare "one little injection" to "I don't scream, but I clamp my jaw so tightly it clicks. I arch my back so much I end up looking behind me at the door."
That doctor was incredibly negligent about pain management.
There's a level called 'unconscionable pain' that is essentially always malpractice, and if you're clamping your jaw and arching your back reflexively, you've hit it and then some.
There's no reason not to mildly sedate a patient, and no reason why anyone should suffer undue pain. Sure, it'll hurt during recovery, but that's why they should issue with vicodin.
Isn't that a little much? The procedure sounds identical to a vasectomy except the very last step -- instead of cutting the vas deferens you inject this substance into them.
As you like to say, RTFA. They are both surgical procedures and the procedures are _identical_: make a hole or cut in the scrotum, pull out the vas deferens. In a vasectomy, you now cut the vas deferens. In a RISUG, you now inject the fluid into the vas deferens. Push the vas deferens back into the scrotum, repeat on the other testicle, and cover the wound. Both procedures can be done through a very small opening that requires no stitches, in a doctor's office, in under half an hour.
