Heard on a tv commercial for meds for this condition that 50% of men over 40 have this.
Being over 40 I take the saw palmetto berry,it works.
Also try to keep prolactin levels in check as these can cause prostate enlargment issues.Deprenyl,bromocryptine,carbogoline(don't know to much about this one tho),vitex,L-Dopa,anything with dopamine agonist properties are good.Any of the SSRI's are serotonergic thus decreasing dopamine,thus raising prolactin levels.Even L-tryptophan and 5HTP raise prolactin also.
