本实验采用正常成年雄性犬15只,分别在输精管中注入蒸馏水或生理盐水,观察其对精子发生的影响,结果发现二者均能引起犬的睾丸明显生精障碍,与对照组差别显著;附睾精子数量和活力大多降低,但未能达到所有附睾完全无精。作者认为本法是一种较有前途的男子节育方法,值得进一步研究探讨。 In this experiment, 15 normal adult male dogs were injected distilled water or saline into the vas deferens respectively to observe their effects on spermatogenesis.
