October 2011 in “British Journal of Dermatology” This study found that four microRNAs, which were significantly upregulated in balding hair follicle papilla cells, could play a role in the development of male pattern baldness.
28 citations
,
August 2011 in “Journal of The American Academy of Dermatology” This study found that men with early-onset androgenetic alopecia had significantly larger prostate volumes and lower urinary flow rates compared to healthy controls, suggesting a possible link between AGA and prostate-related urinary symptoms.
38 citations
,
February 2011 in “Annals of Oncology” This study found that early-onset androgenic alopecia is associated with a higher risk of developing prostate cancer, although it was not linked to earlier diagnosis or more aggressive tumors.
122 citations
,
November 2010 in “Journal of Dermatological Science” This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.
28 citations
,
June 2010 in “European Journal of Cancer” This study found that androgenic alopecia at an early age was associated with a lower risk of prostate cancer, contrary to assumptions about androgens' role.
29 citations
,
March 2010 in “Cancer epidemiology” This study found that early-onset male pattern baldness was associated with a reduced relative risk of prostate cancer.
21 citations

January 2008 in “The Aging Male” This study found no difference in male pattern baldness between patients with benign prostate hyperplasia and prostate cancer, and no correlation with serum androgen levels.
299 citations
,
March 2001 in “Journal of Investigative Dermatology” This study found that specific genetic markers near the androgen receptor gene are significantly more common in men with male pattern baldness, suggesting a genetic component in its development.
127 citations
,
March 1999 in “International Journal of Cancer” This study from Athens, Greece observed that urban living may increase prostate cancer risk, while early adulthood sexual activity might inversely relate to this risk.
