title: Successful pregnancy after microfertilization with epididymal sperm retrieved by micropuncture technique in the patient with congenital absence of the vas deferens.
abstract: A case report describes successful microfertilization of oocytes of a 27-year-old woman with epididymal sperm retrieved by micropuncture technique from the patient with congenital absence of the vas deferens. Microfertilization treatment resulted in a singleton pregnancy; the child has since been born. Treatment of couples involving men with surgically unreconstructible obstruction is now possible. Our experience indicates that sperm retrieved with this new technique, when combined with assisted reproductive technologies, permits fertilization for the men with surgically irreparable vasal obstruction.
