摘要
In a recent publication appearing in the Asian Journal of Andrology, a team of researchers investigated the relationship of early hormone exposure to adult lung function. In the publication, ＇Second to fourth digit ratio： a predictor of adult lung function＇, Park et al.,＇ described known sexual dimorphisms in lung function and a role for sex hormones in the development and regulation of lung function： the predominantly-male hormone, testosterone, enhances airway inflammation and the predominantly female hormone, estrogen, promotes lung development and protects against inflammation. Increasingly over the last decade and a half, digit ratio （the ratio of the lengths of the index to ring fingers） has served as a convenient biomarker for prenatal steroid exposure, and is thought to depend on exposure to testosterone relative to estrogen during development.
