My husband had a vasectomy 1 1/2 yrs. ago. He was sore for a few days, he had brusing and some pain. I think he probably received a prescription from the doctor for the pain. After a few days he was fine, we went on vacation a week later!
I don't think a cold will have anything to do with his recovery, it may just be a little more frustrating for him to have a cold while recovering.
I have 3 kids, 13, 10 and almost 2 yrs. 2 boys, 1 girl. My husband and I say we'd like another child (wink, wink) but he's not willing to reverse the vasectomy and I wouldn't want him to. I'm 37yrs. and my husband is 41yrs.,we are definately done having kids, I'm grateful and blessed for what I have.
