Flushing the vasa deferentia (ductus deferentes) at the time of vasectomy reduced to zero the number of intact spermatozoa by postvasectomy day 6 in the dog and by postvasectomy day 7 in the cat and shortened the time from vasectomy to azoospermia in the dog, but not in the cat. The fluid used to flush the vasa deferentia was not eliminated through the penile urethra, but flowed into the urinary bladder, indicating that the least resistant pathway for the exit of vasal content in the anesthetized dog and cat is toward the urinary bladder. Both control and treated dogs and cats had spermatozoa in the urine obtained by cystocentesis immediately after ejaculation or ejaculation and flushing of the vasa deferentia. Flushing the vasa deferentia at the time of vasectomy is easy to do, safe, and can be used in clinical practice to decrease the time from vasectomy to the safe utilization of dogs and cats as teasers. The procedure has potential application to males of other species.
输精管结扎时冲洗输精管，可使犬在输精管结扎后第6天、猫在输精管结扎后第7天的完整精子数量降至零，并缩短了犬从输精管结扎到无精子症的时间，但猫未缩短。用于冲洗输精管的液体并非通过阴茎尿道排出，而是流入膀胱，这表明在麻醉的犬和猫中，输精管内容物排出的阻力最小的途径是朝向膀胱。在射精后或射精及冲洗输精管后立即通过膀胱穿刺获取的尿液中，对照和处理过的犬和猫都有精子。输精管结扎时冲洗输精管操作简便、安全，可用于临床实践，以缩短犬和猫作为诱情动物从输精管结扎到安全利用的时间。该方法可能适用于其他物种的雄性动物。
