Get stronger without taking medication

(Dr. Cheng Jianming, Director of Urology at Shanghai Seventh Hospital)
Perform 50 deep squats daily: feet parallel and shoulder-width apart, slowly squat down.
Second, perform Kegel exercises: before exercising, empty your bladder. Bend your knees and try to strengthen your pelvic floor muscles.

Three sets daily, 10 repetitions each. For most men, you can see amazing results after three months.
