睾酮能够重新塑造雌性大鼠脑的形状,使其看起来象雄性大鼠的脑。这一结果可以解释在有异性转化欲者中发现的脑差异。雌性与雄性的脑结构在某些方面有所不同。例如,雄性大鼠与性激发有关的脑区——中扁桃体区大于雌性大鼠。此类差异被认为是永久性的。
Testosterone reshapes the shape of the female rat brain, making it look like the brain of a male rat. This result may explain the brain differences found in those who have heterosexual transformation. The brain structure of females and males differs in some ways. For example, male rats have more brain regions associated with sexual excitation than those female rats. Such differences are considered as permanent.
