Statin effects on hormones and erectile function in middle-aged men

A Randomized Controlled Trial of Statin Therapy Effect on Androgen Status and Erectile Function in Men With High and Very High Cardiovascular Risk

Phase 2 Interventional Lomonosov Moscow State University Medical Research and Educational Center · NCT07460960

This will test whether different doses of pitavastatin or rosuvastatin change sex hormone levels and improve erectile function in sexually active men aged 40-65 with high cardiovascular risk.

What this trial studies

This randomized phase 2 trial plans to enroll 150 sexually active men aged 40-65 with high or very high cardiovascular risk. Participants will be randomized to pitavastatin (starting 1 mg/day, with possible titration to 2-4 mg/day) or rosuvastatin (starting 20 mg/day, with possible titration to 40 mg/day) and undergo dose adjustment after three months based on biochemical monitoring. The study will measure androgen profiles, standardized erectile function scores, arterial stiffness, endothelial function, and traditional cardiovascular risk factors at baseline and follow-up. Investigators will compare changes between groups and examine links between sex hormones, erectile parameters, and vascular measures.

Who should consider this trial

Good fit: Men aged 40-65 who are sexually active, have high or very high cardiovascular risk, have not used statins in the past 3 months, and can attend clinic visits in Moscow are ideal candidates.

Not a fit: Men with known statin intolerance, diagnosed hypogonadism, persistent atrial fibrillation, active cancer requiring treatment, chronic inflammatory diseases, severe renal or liver impairment, or chronic heart failure are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the results could help identify statin types and doses that protect heart health while preserving or improving hormone balance and erectile function in at-risk men.

How similar studies have performed: Previous studies are mixed: some small trials and observational studies suggest statins can improve endothelial function and sometimes erectile function, but effects on androgen levels are inconsistent and not well established.
