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.
