Can't Find What You're Looking For?

Sunday, March 30, 2008


Although vasectomies should primarily be considered irreversible, vasectomy reversal is sometimes possible using vasovasostomy (a form of microsurgery).

Vasectomy reversal is, however, not effective in all cases, with the success rate depending on such factors as the method used for the vasectomy and the length of time that has passed since the vasectomy was performed. There is evidence that men who have had a vasectomy produce abnormal sperm, which would explain why even a mechanically successful reversal does not always restore fertility.

In one study, vasectomy reversal was found to be 75% effective for reducing the symptoms of chronic post-vasectomy pain.

In order to allow a possibility of reproduction (via artificial insemination) after vasectomy, some men opt for cryostorage of sperm before sterilization, and although the long term viability of spermatozoa in cryostorage is unknown, some experts advise that this be done before vasectomy.
