Three of us on the team have had it done in the past year (Masters team
). 2 of us were off the bike for 1 week, then back on the road with no problem on post-op day #7. I tried the rollers on POD#5, no good. I gingerly hopped off after 5 minutes. Not sure what was up with the 3rd guy, but he did have a hematoma that set him back about a week.
Two main points: were your tightest bibs shorts over a pair of snug underwear with all sorts of little ice packs in there. Frozen peas are generally recommended but pretty damn bulky. You can find little moldable ice packs that are meant for lunch boxes -- they are great. The urologist will tell you just a pair of snug underwear. That is not enough support. You don't want your boys moving AT ALL. Trust me. As cyclists, we have access to much better compression/support than pretty much any other person on the planet. Second point: do NOT skip your semen analysis x 2. Do it, don't be lazy. Do it. Why? I know 2 guys that both have an "oops!" child conceived after their vasectomy b/c they did not do both checks (usually 12 weeks and 14 weeks later)
It's really not too bad and considering that our wives pushed out a few kids, is a very nice/sacrificial/brave way to "take one for the team".
