@Loz I have to agree with you on this. My informal survey of vasectomized men has yielded 1/3 in some sort of ongoing pain and 2/3 regretting the vasectomy. (And strangely, some of the “1/3 group” didn’t regret their vasectomy.) My view of a successful vasectomy is no pain, no sexual changes, and no patient regrets. If 1 out of 3 is your best result (which may or may not fit my previously mentioned definition of success), the odds are horrible. At what point do you ban a surgery? How bad do the odds have to be?
