Hair loss prevention does lower PSA


UroToday – Effect of 1 mg/day Finasteride on Concentrations of Serum
Prostate-Specific Antigen in Men with Androgenic Alopecia: A Randomized
Controlled Trial

At completion of the study, 1mg/day finasteride resulted in a median serum
PSA decrease of 40% (95% CI 34 to 46) in men ages 40-49 years (mean PSA
0.8 ng/ml) and 50% in men ages 50 to 60 years (mean PSA 1.1 ng/ml). These
were statistically significantly different from decreases in PSA in men
taking placebo for both age groups [0% (mean PSA 1.0 ng/ml) and +13% (mean
PSA 1.2 ng/ml) respectively].

It was felt that even low doses of finasteride may lower PSA. According to this well done study it appears that the PSA is lowered by 40-50%.
Patients should make sure they tell their physicians if they are taking medicines to prevent hair loss.
There are other studies that show that this medicine in higher doses may lower the risk of developing prostate cancer, but a higher percentage of cancers were high grade. It would be a good idea to discuss your use of this medicine with your PMD or urologist.
