Based on pre-experiment foundation of the earlier period, 60 male patients among 45-65 year old were chosed as the clinical case according to the PADAM diagnosis standard, and were divided into 3 groups according to the block stochastic principle, the observation group (acupuncture combined with BUSEHN capsule), group 1, group 2 (takes orally BUSEHN capsule group), each group had 20 cases, and each group of patients was measured by the method of radio-immunity for the serum level of testosterone, luteinizing hormoha, follicle-stimulating hormone before and after the treatment. By the contrast of the grade of PADAM symptom among three groups before and after treatment ,we can reveal the whole funcamental characteristic of acupuncture combined with herb ,and discuss a new way to enhance the curative effect of acupuncture ,and summarize the endocrinous adjustment of acupuncture for the PADAM's patients and the orchidic improvement by the treatment of acupuncture.
