Non-Hair Benefits of Propecia

I read something that suggests that Propecia has other benefits besides hair loss. Is this true and if so, you you expand upon it?

Finasteride has many suspected benefits. Those that I’ve observed include better urination for elderly men with a poor urinary stream, less nightly urination (for people who may have early prostate enlargement) and an increased sex drive in about 1 in 10 men of all ages. Other potential benefits might include a slowing of the buildup of new hair in the nose and ears, a slowing of the building of new hair in the chest, and based upon a new article in the literature (J Dermatolog Treat. 2005 Apr;16(2):75-8) a new treatment to control symptoms for people who have a sweating disorder (Hidradenitis Suppurativa).

The greatest benefit may be the reduction of risks of prostate cancer, something that all men, if they live long enough, will develop. This has been well documented in the literature.

The dose for all of these potential benefits were obtained when finasteride was given in 5mg doses, but some people feel that similar benefits may be obtained with the lower dose of finasteride in Propecia.
