Exclusion Criteria:

  • - Subjects with obvious congenital malformations or anatomical abnormalities of the genitalia that significantly impair penile erection.

  • Subjects with a history of anti-androgen therapy, or androgen replacement therapy initiated less than 3 months prior to screening without a stable maintenance regimen.
  • Subjects with poorly controlled diabetes mellitus, defined as fasting blood glucose >1.5 times the upper limit of normal (ULN), or those with diabetic complications (diabetic nephropathy, peripheral neuropathy).

  • Subjects with a history of severe chronic or acute hepatitis.
  • Subjects who have used vacuum constriction devices (VCD), intracavernosal injections (ICI), or other ED therapies and are unable to discontinue these treatments during the study.
  • Subjects with known color vision abnormalities, retinitis pigmentosa, macular degeneration, non-arteritic anterior ischemic optic neuropathy (NAION), or other fundus disease histories.
  • Subjects with severe central nervous system damage within the past 6 months (cerebrovascular diseases such as cerebral hemorrhage or ischemia, inflammatory brain diseases such as encephalitis or meningitis, craniocerebral trauma, or spinal cord injury), or peripheral nervous system injury or lesions.
  • Subjects with a history of high-risk arrhythmias, or ECG-confirmed arrhythmias, or those with clinically significant abnormal ECG findings at screening as judged by the Investigator.
  • Subjects with a history of malignant tumors within the past 3 years (excluding basal cell carcinoma, squamous cell carcinoma of the skin, or other non-invasive lesions deemed cured by the Investigator with minimal recurrence risk).
