benign prostatic hyperplasia
"Age 63, using finasteride for 2 years and no other medications.  Took many months for improvement in urination and now much improved though definitely not what it was when I was young.  I am no longer scouting for spots to stop in a 30 minute walk.  I typically sleep about 5 hours at night before having to get up.  Other changes since beginning dosage: ejaculation volume has decreased, occasional but rare loss of erection during intercourse. No other changes noticed, in particular no loss of libido, and no mental changes noticed. After doing the research physiological effects seem to be the same at 1mg (for hair loss) as 5mg (for BPH) so I quarter the 5mg pills and take a 1/4 pill per day."
