Why offer a money-back guarantee on the surgeon's portion of the vasectomy reversal cost? Dr. Buch is confident in the excellent pregnancy success rates patients have experienced, both first-time attempts, and the ‘redo’ cases of previously failed surgeries. A full refund on the surgeon’s vasectomy reversal cost will be given for a first time procedure 9 years or less from the time of the vas surgery that fails to return sperm to the ejaculate by one year. A 50 % refund of the surgeon’s portion of the vasectomy reversal cost will be refunded if sperm fails to return to ejaculation on a redo or if it has been 10 years or more since your operation.
