I have a question regarding the difference between Vasclip (clipping of vas deferens) vs. traditional vasectomy.
There was a study showing a possible association between vasectomy and a rare form of dementa (http://www.northwestern.edu/newscenter/stories/2007/02/vasectomy.html).
I realize this is far from conclusive, but there is a theory that sperm entering the blood via vasectomy may lead to antibodies that eventually damage the brain.
My question is whether simple clipping of the vas deferens (Vasclip) would or would not allow sperm to enter the bloodstream? If not, perhaps the possible risk of dementia could be reduced or avoided in comparison to vasectomy?
Thanks for any thoughts or input.
