Not that I recall
For my procedure, they injected numbing medicine up by the root of the shaft, where the nerves run down. Then they made a small incision in the scrotum, fished out the vas deferens (the tube that carries sperm) and burned it through. Some procedures cut out a portion, some I think rely just on cautery (or a combo of both).
The majority of ejaculation is fluid coming from the prostate, which is unaffected by a vasectomy. IIRC there was a little brown in there from old blood but nothing too weird. You do need to 'flush the pipes' a bit to remove any lingering swimmers as they can hang out for quite a while in the plumbing. Hopefully you get a post-vas sperm check to make sure they cut the right pipes (there are blood vessels and ligaments they might cut by mistake) and they stay sealed. It's possible for the cut ends to reattach.
Sperm still gets made but has no where to go, if everything goes well they just get reabsorbed (over and over and over) and you go on to carefree blasting
Personally a vasectomy is the BEST sterility option as it puts it in your control. Birth control pills get more and more hazardous for women as they age, condoms are for chumps (if you are in a monogamous relationship), a tubal ligation (basically a vasectomy for a women cutting the tubes from the ovaries to the uterus) is a MUCH more invasive procedure unless they are already there during a C-section delivery, and all the other birth control things like IUDs, the cup, withdrawal, or "it's my safe day" are more impactful for the woman or straight gambles at best.
Barring a call to repopulate the world, I suppose, but in that case I'll just have to forget some of my medical history
