androgenetic alopecia AGA digit ratio 2D:4D prenatal androgen exposure male pattern baldness

Studysummary The study found that males with androgenetic alopecia had a significantly lower left-hand 2D:4D digit ratio compared to healthy controls, suggesting this ratio may help estimate future AGA risk.

The study investigated the relationship between digit ratio 2D:4D and androgenetic alopecia (AGA) in males. The left-hand digit ratio 2D:4D was found to be lower in AGA patients, indicating that it can be used as an estimation tool for AGA development in the future. However, there was no correlation between digit ratio and age of onset or AGA severity. The study suggests that prenatal androgen exposure may be linked to AGA development. Further studies with larger sample sizes are needed to confirm these findings.

This study concluded that the digit-length ratio (2D:4D) does not predict androgenic alopecia development, suggesting prenatal androgen exposure does not predispose men to this condition.
