    TLDR CAG repeat numbers in the AR gene likely don't affect male pattern baldness in Korean men.
    The study investigated the association between CAG repeat numbers in the androgen receptor (AR) gene and androgenetic alopecia (AGA) in 64 male Korean patients compared to 40 normal male controls. The results showed no significant difference in CAG repeat numbers between the AGA patients and controls, nor any significant correlation between CAG repeat numbers and the age of onset or severity of AGA. The study concluded that AR receptor CAG polymorphisms might not play a major role in the susceptibility to AGA expression in the Korean male population.
