Twenty male cats were treated once or twice with 1 watt/sq cm of ultrasound for 10 minutes. Each of 24 male dogs received one to three treatments with 1 watt/sq cm for 10 minutes. Another six dogs were treated with 2 watts/sq cm for 15 minutes. Four Cebus apella monkeys were treated with the same dosage as that used for the cats and dogs. A dosage of 1 watt/sq cm for 10 minutes was also applied to four human patients without the use of anesthetics, and no pain or side effects were noted. In all treated animals as well as in human patients the results indicate that ultrasound significantly suppresses spermatogenesis according to the dosage and frequency of treatment, without any effect on Leydig cells or blood testosterone levels.
二十只雄性猫接受了一次或两次强度为1瓦/平方厘米的超声波治疗，每次治疗10分钟。二十四只雄性狗每只接受了一至三次强度为1瓦/平方厘米、每次10分钟的治疗。另外六只狗接受了强度为2瓦/平方厘米、持续15分钟的治疗。四只僧帽猴接受了与猫和狗相同剂量的治疗。在未使用麻醉剂的情况下，对四名人类患者也施加了强度为1瓦/平方厘米、持续10分钟的剂量，且未观察到疼痛或副作用。在所有接受治疗的动物以及人类患者中，结果表明，根据治疗剂量和频率，超声波能显著抑制精子发生，而对睾丸间质细胞或血液睾酮水平没有任何影响。
