Thanks for your help. In the meantime let me tell you what I do know. There should not be any difference in sexual performance or libido as there is no hormonal change taking place. When the vas defrens are cut, sperm is no longer in the ejaculate. However, sperm is still produced, they are now absorbed by the body.
Some men find that when there is no risk of pregnancy, their libido actually increases.
A good urologist should be able to advise you on the availability of a sperm bank and also will give you the odds on reconnection if you should decide to have children at a later time. Most often this procedure is not extremely successful and vasectomy should be considered a permanent form of sterilization. Be sure you do not have doubts before you choose this option.
