Comparison Of Finasteride (Proscar) And Serenoa Repens (Permixon) In The Inhibition Of 5-alpha Reductase In Healthy Male Volunteers

Effect None
Trial Design Double blind
Trial Length 1-7 Days
Number of Subjects 32
Gender Male
Age Range 18-29, 30-44
Notes for this study:
80mg of a lipidosterolic extract of saw palmetto (Permixon) taken twice daily for a total daily dose of 160mg over the course of a week failed to influence testosterone or DHT concentrations in otherwise healthy young men; finasteride as the reference drug was effective in acutely reducing and maintaining a reduction of DHT.
