Operative Recovery of Vasal Sperm From Anejaculatory Men: Preliminary Report

Abstract

Sperm showing good motility and function, as demonstrated by the in vitro sperm penetration assay using hamster ova, were collected from the vas deferens of 3 men with ejaculatory failure. The collection procedure may be repeated over multiple ovulatory cycles. The sperm may be used to attempt artificial insemination or in vitro fertilization.

Erectile function and male reproduction in men with spinal cord injury: a review

“…Surgical procedures for sperm retrieval include the testicular sperm extraction (TESE) and epididymal or vas deferens spermatozoal aspiration. Some authors have reported successful sperm retrieval from the vas deferens (Chen et al, 1998) and from implanted sperm reservoirs in SCI men (Berger et al, 1986;Brindley et al, 1986;Bustillo & Rajfer, 1986;Macourt et al, 1991). The sperm recovery rate from SCI men ranges from 86% to 100% Hirsh et al, 1993;Dahlberg et al, 1995;Lochner-Ernst et al, 1997).…”

Vas Cannulation with Implanted Sperm Reservoirs for Obstructive Azoospermia or Ejaculatory Failure

Berger et al (1986) described the operative recovery of motile spermatozoa by repeated vasotomy but have yet to report a pregnancy.…”
