Male pattern baldness (MPB) is a common phenomenon with a complex mode of inheritance. A recent report has implicated the androgen receptor gene in MPB, but this result has not been confirmed. We analyzed a silent polymorphism in the androgen receptor gene (AR) in a group of 41 bald males and 39 non-bald males, and found a significant association (p < 0.0026), thus confirming the previously reported association between MPB and the AR gene.
