Abstract

A cup-shaped silicone-dacron prosthesis that may be used as a sperm reservoir was developed. Spermatozoa aspirated from this reservoir and stored as pellets in liquid N2 for 6 wk induced pregnancies and normal births in 50% of inseminated cows. Because of aplasia or long stenosis of the vas deferens 26 prostheses were implanted upon the epididymis in 14 patients. Percutaneous aspirations up to 7 mo. postsurgery showed 0.3 to 105 million spermatozoa, the quality and quantity of which decreased with time. Insemination of patients'' wives has not resulted in pregnancy.
