title: Sperm cryopreservation and in vitro fertilization/intracytoplasmic sperm injection in men with congenital bilateral absence of the vas deferens: a success story.
abstract: In this study we evaluate the use of cryopreservation of sperm obtained at the time of surgical exploration in men with congenital bilateral absence of the vas deferens. We assess the impact of cryopreservation on pregnancy rates after IVF/intracytoplasmic sperm injection. Intraoperative cryopreservation of sperm at the time of microsurgical epididymal sperm aspiration in men with congenital bilateral absence of the vas deferens resulted in a 100% live delivery rate per couple, providing the highest pregnancy rates of any infertility treatment.
