This study examined the effects of hormones, head size, and oral temperatures on latencies and amplitudes of the auditory brainstem response in 10 young women, 10 young men, and 5 postmenopausal women. Significant gender differences between men's and women's auditory brainstem responses were confirmed. Men showed longer latencies and smaller amplitudes than women. Results showed that oral temperature has little effect on auditory brainstem response latencies and amplitudes. Head size affects waves III, V, and the amplitude of wave V, but is not entirely responsible for the gender latency difference. By examining young women with normal monthly hormonal cycles, significant changes in the absolute latencies of wave V were observed. These changes were correlated with hormonal changes as measured from venous blood samples. It was concluded that the etiology of the gender difference is a combination of hormonal and head-size differences.
本研究检测了激素、头部大小和口腔温度对10名年轻女性、10名年轻男性及5名绝经后女性听觉脑干反应潜伏期及波幅的影响。证实了男性和女性听觉脑干反应存在显著的性别差异。男性的潜伏期比女性长,波幅比女性小。结果显示,口腔温度对听觉脑干反应潜伏期及波幅影响甚微。头部大小影响Ⅲ波、Ⅴ波以及Ⅴ波的波幅,但并非造成性别潜伏期差异的全部原因。通过对月经周期正常的年轻女性进行检测,观察到Ⅴ波绝对潜伏期有显著变化。这些变化与静脉血样本检测的激素变化相关。得出的结论是,性别差异的病因是激素和头部大小差异共同作用的结果。
