[Surgical possibility for refertilization of the male (author's transl)].
With the rising number of vasectomies the demand for refertilization procedures is increasing. Following vasovasostomy patency is achieved in 80 to 90% and fertility in up to 30%. About half of these figures are attained by epididymo-vasostomy. Encouraging experimental studies with an alloplastic sperm-reservoir justify its clinical application. Reasons for failure and for the discrepancy between patency and fertility following refertilization are: surgical technique, autoimmunization, adynamia and hyperactive phagocytosis within the epididymis.
