Alloplastic spermatoceles: a 5-year experience

We implanted 14 alloplastic spermatoceles in 8 patients with congenital absence or atresia of the vas deferens or anejaculation. The surgical technique and results of aspirations are detailed. Five spermatoceles yielded sperm: 2 for prolonged periods (4 1/2 to 11 months) and 1 produced motile sperm considered adequate for artificial insemination.
