The etiology of non-occupational carpal tunnel syndrome is not well understood. It is proposed that carpal tunnel syndrome can develop during sexual intercourse when the hands become repeatedly extended while under pressure from the weight of the upper body. Of the eight risk factors associated with non-occupational carpal tunnel syndrome, age, marital status, pregnancy and use of hormonal agents can be explained by changes in the frequency of sexual intercourse. On the other hand, obesity, macromastia and large chest circumference can be explained by the increased pressure imposed on the wrists by the heavier upper body associated with such conditions. The bilaterality of carpal tunnel syndrome can be explained by the fact that both hands are needed to support the upper body during sexual intercourse. A parallel decrease in the frequency of sexual intercourse and the incidence of carpal tunnel syndrome between the sixth and the seventh decades of life suggests a possible cause and effect relationship between sexual intercourse and carpal tunnel syndrome.
非职业性腕管综合征的病因尚不清楚。有人提出，在性交过程中，当双手在承受上半身重量的压力下反复伸展时，可能会发生腕管综合征。在与非职业性腕管综合征相关的 8 个危险因素中，年龄、婚姻状况、妊娠和使用激素制剂可以通过性交频率的变化来解释。另一方面，肥胖、巨乳症和大胸围可以通过与这些情况相关的较重上半身对手腕施加的压力增加来解释。腕管综合征的双侧性可以通过在性交过程中双手都需要支撑上半身这一事实来解释。在 60 到 70 岁之间，性活动频率和腕管综合征的发生率呈平行下降，这表明性活动与腕管综合征之间可能存在因果关系。
