• Clinical diagnosis of mild to moderate erectile dysfunction, IIEF-5 questionnaire score ≤ 21 points, duration of at least 3 months (subject to signing informed consent);
• Subjects (including partners) guarantee that they have no plans to father a child or donate sperm during the study and for 3 months after the last dose and voluntarily take appropriate contraceptive measures;
• After the screening run-in period, the following three conditions were met simultaneously:
• \) At least 4 attempts at sexual intercourse during the run-in period; 2) Has a failure rate of ≥ 50% of attempts to intercourse (failure to intercourse is defined as having at least one of the three questions answered on the SEP); 3) IIEF-EF score ≥ 11 and ≤ 25.

You may not qualify if:

• History of stroke within 6 months prior to informed consent;
• Patients who have received or are receiving anti-androgen therapy, or have a history of androgen replacement therapy and are stable for less than 3 months;
• Patients scheduled for CABG, PCI, heart transplantation, SAVR/TAVR during the study period;

• Combined with abnormal liver function, defined as AST and/or ALT more than 2 times the upper limit of normal;
• Combined with severe renal dysfunction, defined as glomerular filtration rate \< 30.0 mL/min/1.73m ² calculated by CKD-EPI formula;
• Subjects who have used vacuum aspiration (VCD), intracavernosal injection (ICI) therapy or other drugs to treat erectile dysfunction and cannot interrupt the above treatment during the study;
• Patients who have severe central nervous system injury (cerebral vascular diseases such as cerebral hemorrhage or ischemia, brain inflammatory diseases such as encephalitis or meningitis, craniocerebral trauma or spinal cord injury), or peripheral nervous system injury or lesions within 6 months before signing the informed consent;
• History of myopathy/myalgia, or susceptibility to myopathy/rhabdomyolysis (e.g., family history of hereditary myopathy, previous use of HMG-CoA reductase inhibitors in combination with fibrates, etc.);
• Presenting with hypothyroidism, defined as marked TSH elevations (usually \> 1.5 ULN) associated with decreases in free T4 (FT4) ;
