Gender identity depends largely on postnatal environmental influences, while sex-dimorphic behavior and temperamental sex differences appear to be modified by prenatal sex hormones. A role of the prenatal endocrine milieu in the development of erotic partner preference, as in hetero-, homo-, or bisexual orientation, or of cognitive sex differences has not been conclusively demonstrated.
性别认同很大程度上取决于出生后的环境影响,而两性异形行为和气质性别的差异似乎受到产前性激素的影响。产前内分泌环境在异性恋、同性恋或双性恋取向的性伴侣偏好发展中所起的作用,或者认知性别差异方面,尚未得到确凿证实。
