We developed a cup-shaped silicone-dacron prosthesis that may be used as a sperm reservoir. Spermatozoa aspirated from this reservoir and stored as pellets in liquid nitrogen for 6 weeks induced pregnancies and normal births in 50 per cent 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 months 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.
我们研发了一种杯状硅橡胶-涤纶假体，可作为精子储存器。从该储存器吸出的精子制成颗粒保存在液氮中6周后，50%的授精母牛成功怀孕并正常产犊。由于输精管发育不全或严重狭窄，14例患者在附睾上植入了26个假体。术后长达7个月的经皮抽吸显示，精子数量为0.3至1.05亿个，其质量和数量均随时间下降。对患者妻子进行授精尚未导致怀孕。
