Im looking to participate in a mens health syudy. I cant find and through searches?

Typically doctors have information about available studies, especiall those involved with any teaching programs (programs with med students and resident physicians). You can actually call a department - try Urology - at a University hospital and ask if they are looking for subjects for clinical trials. These days, many look at lifestyle, diet, suppliments over time and are continually enlisting participants. Best Wishes.
