- Changes in EF(Erectile Function) Domain [ Time Frame: 12 weeks ]
EF(erectile function, score 0-20) domain was measured in study visit 1(0 week) and visit 3(12 week).
The original index consists of 4 Questions. Individual question response is assigned a score of between 0 (worst) to 5 (best) and summed to form a score ranging from 0 (worst) to 20 (best).
- Changes in MSHQ (Male Sexual Health Questionnaire) [ Time Frame: 12 weeks ]
MSHQ(Male Sexual Health Questionnaire) was measured in study visit 1(0 week) and visit 3(12 week).
The total MSHQ score (25 questions) ranges from 17-130, with higher scores indicating greater sexual function.
- GEAQ (Global Efficacy Assessment Question) [ Time Frame: after 12weeks of consumption ]
- Changes in Uroflowmetry(Max Flow Rate) [ Time Frame: 12 weeks ]uroflowmetry(max flow rate) was measured in study visit 1(0 week) and visit 3(12 week).
- Changes in IIEF(International Index of Erectile Function)-Total Domain [ Time Frame: 12 weeks ]
IIEF(International Index of Erectile Function)-total domain(score range: 5-75) was measured in study visit 1(0 week) and visit 3(12 week).
IIEF includes 15 questions and addresses the 5 sub-domains of Erectile function, Intercourse satisfaction, Orgasm function, Sexual desire, and Overall satisfaction.
The IIEF-total domain is the sum of sub-domains. Lower scores indicate severe erectile dysfunction, while higher scores indicate less erectile dysfunction.
