Spanish study confirms link between premature baldness and prostate enlargement

Tuesday, 20 March 2012- Spanish scientists have confirmed that there is a clear relationship between androgenetic alopecia (premature baldness) and benign prostate hyperplasia (BPH), a benign enlargement of the prostate that appears in aging men and is associated with certain hormones as dihydrotestosterone.

BPH appears in 50% of men over 60 year old and causes voiding syndrome such as urinary frequency.

In the study published in the Journal of the American Academy of Dermatology, men with premature alopecia are at a higher risk for BPH than the rest of men. The article was awarded the 1st prize at the 68th Annual Conference of the American Academy of Dermatology held in Miami, Florida.

Androgenetic alopecia is the most common form of baldness, and is more frequent in men than in women. It has a hereditary component and gradually evolves when no treatment is provided. Benign prostate hyperplasia is also the most common prostate condition and causes an abnormal and irregular enlargement of the glands adjoining the urethra. This causes the growth of a benign tumor that blocks urine output.

The study included a total of 87 men, of which 45 were diagnosed with androgenetic alopecia by a dermatologist, while the other 42 were healthy men who acted as controls. Measurements were taken of prostate volume by transrectal ultrasound and urinary flow by urinary flowmetry. Hormone levels and International Index of Erectile Function were also assessed.

The results of this study proved that there was a clear and direct association between premature alopecia and benign prostate hyperplasia.
