Abstract

Mean platelet volume (MPV) has been related to erectile dysfunction (ED). However, its value in predicting therapeutic response to phosphodiesterase‐5 inhibitors is not evaluated. This study aimed to investigate the value of MPV as a marker for the prediction of the response of the tadalafil treatment of ED. A retrospective analysis of patients who were admitted to the andrology outpatient clinic between 2020–2022 were performed. The inclusion criteria were, ≥40 years old male, International Index of Erectile Function–Erectile Function domain score < 26, not received any ED treatment before, have a stable heterosexual relationship, and prescribed 5 mg daily tadalafil for primary treatment of ED. A total of 116 patients were included in the study. The mean age of the patients was 53.7 ± 8.7 years. The response rate to 5 mg tadalafil treatment was 52.6% (Group‐1; N = 61). An MPV value 3 10.05 fL was associated with 66% sensitivity and 75,4% specificity for no response to 5 mg daily tadalafil treatment (Area under curve = 76.9% [95% CI 68.2%–85.6%; p < 0.001]). Initial IIEF‐EF score, fasting blood glucose, and MPV level was independently associated with the response to the tadalafil treatment. This is the only study to evaluate the value of MPV level on the therapeutic response of ED to tadalafil. Strict inclusion criteria were applied to the cohort. However, the diagnose of vascular ED has been made by clinical evaluation and retrospective design of the study were the…

How strong is the evidence?

Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 116 participants or records.
