Vasectomy Reversal Vasectomy reversal is a microsurgical procedure in which the inside and outside of the vas deferens are reattached with ultra-fine sutures. Most reversals are done on an outpatient basis. Since vasectomy does not significantly alter a man's ability to produce sperm, an alternative to reversal is sperm aspiration, during which sperm is collected through a needle inserted into the testicle for use in alternative insemination methods.
