Do Statins Lower Testosterone? What the Evidence Says

TL;DR — Key Takeaways

• Statins lower testosterone only slightly, about 4% in men in meta-analyses.
• That drop is statistically real but usually not enough to fall below the normal range.
• Free testosterone appears largely unaffected, and most doctors consider the effect clinically insignificant.
• Mechanism: cholesterol is the building block of testosterone, so blocking cholesterol can nudge it down.
• Don’t stop a prescribed statin, its heart benefits usually outweigh this small effect. Talk to your doctor.

Statins cause a small drop in testosterone, about 4% in men, usually not enough to push you below normal. Because cholesterol is the building block for testosterone, statins that block it can slightly reduce it. Most doctors consider this clinically insignificant, and free testosterone appears largely unaffected. The heart benefits outweigh it, don’t stop a prescribed statin.

Worried your cholesterol medication is tanking your T? The evidence says: barely, if at all. Here’s the honest picture. (Part of our guide on what lowers testosterone; for the overview, our complete TRT guide.)

Do Statins Lower Testosterone?

Yes, but only slightly, and probably not in a way you’d notice. Statins produce a small, statistically significant decrease in testosterone, but studies consistently show it’s not enough to drop you below the normal range.

Key fact: Meta-analyses show statins lower testosterone by about 4% in men, statistically real but usually not enough to drop below the normal range, and free testosterone appears unaffected.

How Much Do Statins Lower Testosterone?

The numbers are reassuringly small:

• A 2013 meta-analysis (Schooling et al.) found statins lowered testosterone by about 4% in men (~11% in women) not below normal.
• A 2024 meta-analysis confirmed a small decrease in total testosterone, again not below normal, with a slight rise in FSH and no significant change in LH, estradiol, SHBG, or free testosterone.

Since free testosterone (the active form see free vs total testosterone) is what matters most and appears unaffected, the practical impact is minimal for most men.

How Statins Could Affect Testosterone

The mechanism is real, even if the effect is small: cholesterol is the obligate precursor your body uses to make all steroid hormones, including testosterone. Statins work by inhibiting HMG-CoA reductase, the enzyme that makes cholesterol. So in theory, less cholesterol could mean slightly less testosterone, which is exactly what the ~4% dip reflects. (This is the flip side of how testosterone therapy interacts with lipids see does TRT affect cholesterol.)

Should You Stop Statins Because of Testosterone?

No not on your own. Statins are prescribed to reduce cardiovascular risk, and that benefit generally far outweighs a ~4% testosterone change that keeps you in the normal range. Stopping a statin over a small, likely-insignificant hormonal effect could be a serious mistake. If you have low-T symptoms, the answer is to investigate the real causes see what lowers testosterone  not to quit a heart medication. Always discuss changes with your doctor.

Do Statins Cause ED or Low Libido?

This is debated. Some men report low libido or erectile issues on statins, but the evidence is mixed and interestingly, statins may improve erectile function in some men by improving blood-vessel health. Any libido effect isn’t clearly explained by the tiny testosterone change. If you have symptoms, get evaluated rather than assuming it’s the statin.

Can You Take TRT With Statins?

Yes they’re commonly used together, and there’s no major conflict. In fact, both relate to cardiovascular and metabolic health, so they’re often managed alongside each other. If you’re on a statin and have confirmed low testosterone, discuss whether TRT is right for you with your doctor done properly, TRT is safe with monitoring.

Conclusion

Do statins lower testosterone? Only slightly about 4% in men, which usually keeps you within the normal range, with free testosterone essentially unaffected. The mechanism (cholesterol is testosterone’s precursor) is real, but the clinical impact is minimal, and most doctors don’t consider it significant. Don’t stop a prescribed statin over this the heart benefits matter far more. If you have low-T symptoms, look for the real causes and talk to your doctor.

Frequently Asked Questions

Do statins lower testosterone?

Slightly. Meta-analyses show statins lower testosterone by about 4% in men, which is statistically significant but usually not enough to drop you below the normal range. Free testosterone appears unaffected, and most doctors consider the effect clinically insignificant.

How much do statins lower testosterone?

About 4% in men according to a 2013 meta-analysis, and a 2024 analysis confirmed a small decrease in total testosterone that stays within the normal range. Free testosterone, LH, estradiol, and SHBG showed no significant change, so the practical impact is minimal.

How do statins lower testosterone?

Cholesterol is the raw material the body uses to make testosterone, and statins block HMG-CoA reductase, the enzyme that produces cholesterol. In theory, less cholesterol could mean slightly less testosterone, which explains the small ~4% dip seen in studies.

Should you stop statins because of testosterone?

No, not on your own. Statins reduce cardiovascular risk, and that benefit usually far outweighs a small testosterone change that keeps you in the normal range. If you have low-T symptoms, investigate other causes and discuss any medication changes with your doctor.

Do statins cause ED or low libido?

The evidence is mixed. Some men report low libido or erectile issues, but statins may also improve erectile function by supporting blood-vessel health. Any libido effect isn’t clearly explained by the tiny testosterone change, so symptoms warrant a proper evaluation.

Can you take TRT with statins?

Yes, they’re commonly used together with no major conflict, and both relate to cardiovascular and metabolic health. If you’re on a statin and have confirmed low testosterone, discuss with your doctor whether TRT is appropriate; it’s safe with proper monitoring.
