Following encouraging results in rats, a similar cup-shaped silicone prosthesis of 1 ml volume 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 weeks. 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.
在大鼠实验取得令人鼓舞的结果后，一种类似的容量为1毫升的杯状硅胶假体在公牛附睾尾部植入了8次。术后长达14天，从该假体采集的样本显示有10%-70%的活动精子。采集到的精子以颗粒形式深度冷冻保存6周。在野外条件下，对8头母牛进行人工授精，其中4头成功怀孕。针对输精管发育不全或长段狭窄患者的临床应用正在进行中。
