Patients should consider vasectomy permanent.
If your objective is merely to space out pregnancies, or if you have even the slightest reason to believe that you might want to have children in the future, then a vasectomy will not suit your purpose and should not be considered.
Cryopreservation (sperm banking or freezing) before vasectomy is available as an option for those men considering vasectomy, though they should understand that use of the sperm requires professional assistance. Although we do not recommend sperm banking for all couples, some couples may elect to pursue this. Vasectomy reversal is also an option, but should not be taken lightly, as this can be costly and is not 100% effective.
