Time Is Tied To Reversal Success
A vasectomy can be reversed after a long period of time (some after twenty-five years), but patients experience a higher success rate if the procedure is done sooner. The reversal is possible because male sperm is continually produced after the initial vasectomy, it is just unable to join the semen and impregnate a woman. However, the body does change after surgery, and this can mean that with time, it is impossible to put the vas deferens back into its proper place. There may be scarring that could prevent the reversal from being entirely successful. Scarring that can occur after the reversal has taken place may prevent the sperm from rejoining the semen, thus rendering the man permanently sterile.
