Testosterone Serenoa repens effects

Testosterone effects. A liposterolic extract of Serenoa repens was administered to 20 men aged 50 to 75 years with BPH at a dose of 160 mg twice daily for 30 days. The extract produced no changes in plasma levels of T, FSH, and luteinizing hormone. The results indicated that Serenoa extract, which is useful in the treatment of BPH, does not act via systemic changes of hormone levels .

Some of the mechanisms proposed include anti-inflammatory activity, blocked conversion of testosterone to dihydrotestosterone and prostate epithelial involution similar to effects...
