Androgenetic alopecia (AGA) is a widespread type of hair loss that affects both males and females. Advanced age and family history of AGA are well-established risk factors for developing AGA. The second to fourth digit ratio (2D:4D) is the ratio between the length of the index and ring fingers. This ratio has been utilized as a predictor for multiple hyperandrogenism-related medical conditions. More recently, 2D:4D was investigated as a predictor for AGA. This article aims to investigate the evidence supporting the use of 2D:4D as a predictor of AGA, and address areas of future research.
雄激素性脱发(AGA)是一种常见的脱发类型,影响男性和女性。高龄和AGA家族史是公认的发生AGA的危险因素。食指与无名指长度比(2D:4D)是食指和无名指长度之间的比值。该比值已被用作多种高雄激素血症相关疾病的预测指标。最近,2D:4D被研究作为AGA的预测指标。本文旨在研究支持将2D:4D用作AGA预测指标的证据,并探讨未来的研究领域。
