Primary Outcome Measures :
  1. 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).



Secondary Outcome Measures :
  1. 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.


  2. GEAQ (Global Efficacy Assessment Question) [ Time Frame: after 12weeks of consumption ]
  3. 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).

  4. 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.
