对7组雄性仓鼠进行10分钟的试验，每隔一周或更长的时间进行一次有性接受性的雌性试验，通过第一次上马的频率、潜伏期和引入来评估阉割后交配行为的保留情况。五组在阉割前有过性经历；1组保持完整。没有发生性行为的那一组在所有方面的得分都明显较低。有经验的雄性比没有经验的雄性更能保持交配行为。与每隔3周或6周测试一次的动物相比，每周测试一次的动物的交配行为明显下降得更快。雄性与雌性的鼻-鼻接触没有因性经验、阉割或检测频率而改变；由于阉割，男性与女性的鼻-肛门接触明显减少。与阉割状态持续时间和测试频率相关的是，在阉割后，雌性的尾巴和后腿被咬拽的次数增加了。经历过阉割的一组每周测试一次，整个测试周期的1/3-1/2都是在这种行为中进行的。
Retention of copulatory behavior after castration was assessed by frequency of and latency to 1st mount and intromission in 7 groups of male hamsters given 10 min tests with a sexually receptive female at weekly or longer intervals. Five groups were sexually experienced prior to castration; 1 group remained intact. The group receiving no precastrational sexual experience scored significantly lower on all measures. Experienced males show longer retention of copulatory behavior than inexperienced males. Animals tested weekly showed a significantly faster decline in copulatory behavior than animals tested at 3 or 6 wk intervals. Males showed no change in nasal-nasal contact with the females due to sexual experience, castration or frequency of testing; nasal-anal contact of male to female decreased significantly as a result of castration. Biting and tugging at the tail and hindquarters of the female increased following castration both in relation to duration of the castrate state and frequency of testing. The castrate sexually experienced group tested weekly spent from 1/3-1/2 of the entire test period in this behavior.
