Hi, Good for you! Making a responsible decision about the reality of more children in a family. I am the mother of four. After my daughter was born my husband and I discussed both possibilities. We decided that since a vasectomy was a 15 minute procedure and a tub ligation was considered major surgery the vasectomy was the right choice.
We have never regretted it. He was back to work in two days and in a week he was back in the saddle so to speak. He had no problems with it and in fact our sex life was better because I wasn't so worried about pregnancies. There was absolutely no change in him due to the vasectomy. I answered alot of embarrasing questions after it was done. Did he change physically? No. Could he still "perform"? absolutely!
To me this 15 minutes out of his life was worth the world.
I'll also add that 8 years later due to masses in my uterus I had to have a hysterectomy. It's the same recovery time as a ligation and it was not pleasant. There are hormomal problems which I handled without medications. Hot flashes, mood swings. But all lessen in time.
I am the mother of 4 children. The boys are 23, 19, 16 and my daughter is 12.
