Do men still produce semen after a vasectomy?
Yes. A vasectomy only gets rid of the sperm, not the semen. Sperm cells only make up a very small percentage of the fluid (10%) so the difference in volume will be practically unnoticible. It will also have the same smell and texture. So in other words, he will still ejaculate fluid, only with a 10% decrease in volume because of the removed sperm cells.
