Groups of male and female ferrets were tested in a T maze to determine whether they preferred to approach and interact with a sexually active male or an estrous female. Control male and female ferrets gonadectomized (GX) on postnatal Day 35 and tested in adulthood while receiving no hormone or testosterone (T) displayed no significant preference. When given estradiol benzoate (EB), however, control males preferred stimulus females whereas control females preferred stimulus males. When tested in adulthood with EB treatment, males GX on postnatal Day 5 showed a significant reduction in their approach to stimulus females, although they did not switch their preference to stimulus males and thereby resemble control females. Female ferrets GX on postnatal Day 5 and given a high dosage of T over postnatal Days 5-20 showed a significant reduction in their approach to stimulus males, although they did not switch their preference to stimulus females, and thereby resemble control males. The results suggest that extended perinatal exposure of male ferrets to T is required for the development of a sociosexual preference for females.
将雄性和雌性雪貂分组，在T型迷宫中进行测试，以确定它们更喜欢接近有性活动的雄性还是处于发情期的雌性并与之互动。出生后第35天进行性腺切除（GX）的对照雄性和雌性雪貂，成年后在不接受任何激素或睾酮（T）的情况下进行测试，未表现出明显偏好。然而，当给予苯甲酸雌二醇（EB）时，对照雄性更喜欢刺激雌性，而对照雌性更喜欢刺激雄性。出生后第5天进行GX的雄性雪貂在成年后接受EB治疗进行测试时，对刺激雌性的接近行为显著减少，尽管它们没有将偏好转向刺激雄性，因此与对照雌性不同。出生后第5天进行GX并在出生后第5至20天给予高剂量T的雌性雪貂，对刺激雄性的接近行为显著减少，尽管它们没有将偏好转向刺激雌性，因此与对照雄性不同。结果表明，雄性雪貂围产期长时间暴露于T是形成对雌性的社会性行为偏好所必需的。
