title: Successful in vitro fertilization and pregnancy by the micromanipulation with sperm from efferent duct retrieved by micropuncture technique in a patient with congenital absence of the vas deferens.
abstract: A case of successful in vitro microfertilization and pregnancy of 30-year-old woman with sperm from efferent duct retrieved by a micropuncture technique combined with perivascular nerve stimulation from a patient with congenital absence of the vas deferens is reported. Treatment of couples involving men with surgically unreconstructible vasal obstruction is now possible. Our experience indicates that sperm from the efferent duct retrieved by this new technique, when combined with assisted reproductive technologies, permit fertilization and subsequent pregnancy for the men with surgically irreparable vasal obstruction.
