Microsurgical Vasovasostomy

Vasovasostomy is a microsurgical procedure to restore fertility after vasectomy, a surgery that sterilizes the patient by severing the vas deferentia, the tubes that carry the sperm from the testes to the penis. After a vasectomy, a patient may have various reasons for wanting to reverse the procedure, such as new opportunities for having children or a new romantic partnership. A vasovasostomy involves reestablishing the flow of sperm through the vas deferens by reconnecting the severed ends of the tube. In 1919, in the United States, William C. Quinby performed the first recorded successful vasovasostomy. Modern improvements on the surgery have led to its adoption as a microsurgery, a procedure that involves a microscope and specialized microscopic instruments. Surgical research over the twentieth century into reconnecting a blocked vas deferens and the resulting microsurgical technique for vasovasostomy has provided a way for people to regain their fertility after a vasectomy.
