A sexually dimorphic cell group is described in the preoptic area of the human hypothalamus. Morphometric analysis revealed that the volume of this nucleus is 2.5 +/- 0.6 times (mean +/- standard error of the mean) as large in men as in women, and contains 2.2 +/- 0.5 times as many cells. Between the ages of 10 and 93 years, the nucleus decreases greatly in volume and in cell number. Although no function has yet been established for this nucleus, it is located within an area that is essential for gonadotropin release and sexual behavior in other mammals.
在人类下丘脑的视前区发现了一个具有性别二态性的细胞群。形态计量学分析显示，该核团的体积在男性中是女性的2.5±0.6倍（平均值±平均值的标准误差），细胞数量是女性的2.2±0.5倍。在10至93岁之间，该核团的体积和细胞数量大幅减少。尽管该核团的功能尚未明确，但它位于对其他哺乳动物促性腺激素释放和性行为至关重要的区域内。
