Can a vasectomy be reversed?
You should consider any vasectomy to be permanent. There are delicate microsurgery operations that may be able to reverse the effects of a vasectomy, but there is no assurance that the flow of sperm can be restored or pregnancy will result in every case. The likelihood of success can vary greatly depending on individual circumstances, including how much time has passed since the vasectomy. If you are seriously considering a vasectomy, it's best to assume that it will be a permanent change.
What happens to the sperm?
This is a mystery to some people, but the answer is both normal and natural. The body absorbs unused sperm cells normally - whether or nor you've had a vasectomy. After the procedure, the testicles will continue to produce sperm, but they will not leave the body in the semen. They dissolve and are simply and naturally absorbed by the body.
Will my sex life be affected?
A vasectomy only blocks sperm and does not affect your sexual drive, your ability to have an erection, orgasm or ejaculation or your ability to have and enjoy sex. Sperm is only a small fraction of the total liquid in your semen. The amount of fluid, intensity - even color and texture - does not appear to change when sperm is absent. Male hormones continue in the bloodstream, and secondary characteristics (such as beard or voice) do not change. Some couples say their relationship is improved by not having to worry about contraceptive techniques or unplanned pregnancy.
