Abstract
Following encouraging results in rats, similar cup-shaped silicone prosthesis of 1 ml vol was implanted 8 times upon the cauda of the epididymis in bulls. Aspirations from this prosthesis showed 10-70% motile spermatozoa up to 14 days after surgery. Aspired spermatozoa were deep-frozen in pellet form for 6 wk. Artificial insemination in 8 cows under field conditions resulted in pregnancies in 4 of them. Clinical application for patients with aplasia or lengthy stenosis of the vas is under way.This publication has 0 references indexed in Scilit:
