DH and I are concerned about doing things as naturally or safe as possible. We have one child from previous relationship and three of our own. We feel we are done. I just got AF back 8 mo PP now so we are thinking along the lines of something permanent. Neither of us want to mess with our bodies, but a vasectomy is still an option. The other option is NFP but we were using it and concieved with our last as I wasn't disciplined enough to do it right. I want a guarantee. I will not get a tubal ligation b/c mom had one and her cycles went all wacky after that - heavy flow, sickness, intense pain, irregularity - threw her into perimenopause, basically. Seems to be in my family so I do not want to go through that. Our concern about vasectomy is the long term effects. I read an article once that said it decreases a man's life expectancy by about 5 years. I have looked on the net and can't find anything and of course every GP will tell me there's no risks. Have you gals come across any info on this? With a vasectomy the sperm has to be re-absorbed by the body - totally unnatural - can this have long term effects? If so, what effects and what is the science behind it?
