作者将装有约12毫克睾酮的2.5厘米长的硅胶管,二端用医用硅胶粘合剂封闭后,植入雄性成熟大鼠的肩骨上部皮下。经过1—2个月后解剖。对交配情况、附生殖器的生化情况以及睾丸的组织学等作了研究。植入一枚睾酮硅胶丸的雄鼠,在1—2个月时,或植入2枚睾酮胶丸一个月的雄鼠,它们附睾中的精子仍有活动能力,交配后雌鼠能正常产仔。植入2枚睾酮硅胶丸二个月的雄鼠,在精母细胞阶段就抑制了精子发育,附睾涂片无精子。间质细胞萎缩,交配后不产仔。将硅胶丸取出后一个月,睾丸组织、附睾中精子的活动能力及生育都恢复正常。 The authors sealed a 2.5 cm long silicone tube containing about 12 mg of testosterone, both ends sealed with a medical silicone adhesive, and then subcutaneously injected into the upper part of the shoulder of a male adult rat. After 1-2 months after the anatomy. The mating situation, with the biochemical conditions of the genitals and testicular histology were studied. Male mice implanted with a testosterone gel at 1 to 2 months, or two testosterone capsules implanted for one month, have sperm motility in the epididymis and normal post-mating females kid. Implantation of two testosterone gel capsules Two-month-old male mice inhibited sperm development at spermatocyte stage with no sperm in the epididymis smear. Interstitial cells atrophy, do not give birth after mating. A month after the removal of the silicone gel, testicular tissue, epididymal sperm motility and fertility are back to normal.
