Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | medical history | at baseline | Medical history refers to a comprehensive record of a patient's past and current health conditions, diseases, treatments, and related health events. |
| Secondary | CDDU | at baseline | Color Doppler Duplex Ultrasonography |
| Secondary | IIEF-5 | at baseline and up to 6 months | The International Index of Erectile Function-5 (IIEF-5) is a validated 5-item self-administered questionnaire used to screen and assess the severity of erectile dysfunction over the preceding 6 months. Each item is scored on a 1-to-5 Likert scale, yielding a total score ranging from 5 (worst) to 25 (best). Severity is classified as follows: 22-25, no ED; 17-21, mild ED; 12-16, mild-to-moderate ED; 8-11, moderate ED; and 5-7, severe ED. Higher total scores indicate better erectile function, while lower scores reflect greater impairment. The IIEF-5 is widely used in both clinical practice and research as a simple, reliable tool for evaluating treatment outcomes. |
| Secondary | EHS | at baseline and at baseline and up to 6 months | The Erection Hardness Score (EHS) is a validated single-item, 4-point self-reported scale used to assess penile rigidity during sexual activity. The scoring criteria are as follows: 1 = the penis is larger but not hard; 2 = the penis is hard but not hard enough for penetration; 3 = the penis is hard enough for penetration but not completely hard; 4 = the penis is completely hard and fully rigid. The total score ranges from 1 (minimum) to 4 (maximum). Higher scores indicate better erection hardness and superior erectile function, while lower scores reflect greater impairment. Due to its simplicity and strong correlation with the IIEF, the EHS is widely used in both clinical practice and research as a quick, reliable tool for monitoring treatment response. |
| Secondary | ALT | at baseline | Alanine Aminotransferase，a key enzyme mainly found in liver cells, serving as a sensitive biomarker for detecting liver damage.Unit of concentration:U/L |
| Secondary | AST | AT baseline | AST stands for Aspartate Aminotransferase, a liver enzyme released into the blood when liver or muscle cells are damaged.Unit of concentration:U/L |
| Secondary | ALP | at baseline | ALP stands for Alkaline Phosphatase, a group of enzymes mainly found in the liver, bile ducts, and bones, which is commonly measured in blood tests to help diagnose liver or bone disorders.Unit of concentration:U/L |
| Secondary | GGT | At baseline | GGT stands for Gamma-Glutamyl Transferase, an enzyme primarily located in the liver, bile ducts, and kidneys, which is commonly measured in blood tests to help diagnose liver, biliary, or pancreatic disorders. Unit of concentration: U/L |
| Secondary | TBIL | AT baseline | TBIL stands for Total Bilirubin, a metabolic product mainly formed from the breakdown of aging red blood cells, which is commonly measured in blood tests to help diagnose liver, biliary, or hemolytic disorders. Unit of concentration: μmol/L |
| Secondary | DBIL | at baseline | DBIL stands for Direct Bilirubin (also known as Conjugated Bilirubin), a water-soluble pigment mainly formed in the liver through the metabolism of red blood cells, which is commonly measured in blood tests to help diagnose liver, biliary, or hemolytic disorders.Unit of concentration: μmol/L |
