Factors predicting successful microsurgical vasectomy reversal.

A man who desires restoration of fertility after vasectomy has two main treatment options for having his genetic child: vasectomy reversal or sperm extraction with subsequent in vitro fertilization with intracytoplasmic sperm injection. Microsurgical reconstructive techniques and their widespread availability have made vasectomy reversal a realistic option for many couples; however, vasectomy reversal outcomes are varied because there are many factors that alter the chance of success. Some of these factors become known preoperatively, whereas others can only be ascertained at the time of surgery. Intraoperatively, the urologist must identify factors and understand how they will affect the decision to proceed. This article systematically reviews each of these phases of decision-making and management.
