NO KIDDING! This question has been asked a few times in the newsgroup, and is in the top ten keywords used to search this site! The threads in the newsgroup came to the conclusion that there is no difference, except for one lady who said her husband's sperm smelled different after he had had a reversal. We also address the questions of volume, colour and consistency of semen after a vasectomy in our on-line survey along with many other important issues. Basically men who have had a vasectomy say that it doesn't affect the qualities mentioned, nor does it affect the consistency or adhesive properties. I.E. it will still stick to dresses, body hair and gum up shower trays and make just as much mess as it always used to.
