TLDR Finger length ratio may indicate male hair loss.
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.

December 2021 in “Physiological Research” Men, particularly those with hair loss, are more likely to get the virus, and those with prostate cancer may have milder symptoms. Testosterone's role in the disease is unclear, and the virus doesn't seem to harm male fertility. Women with PCOS might be at higher risk. More research is needed.
