Testosterone and Cholesterol: What Is the Connection?

By Noophoric Editorial Team Updated August 31, 2026

Short answer: Cholesterol is used to make testosterone, but blood cholesterol and testosterone do not move together in a simple one-to-one relationship. Low testosterone is associated with unfavorable metabolic health in some men, while testosterone therapy can produce small and inconsistent changes in cholesterol levels. Neither testosterone nor a “testosterone booster” should be used as a cholesterol treatment.

Key takeaways

The body uses cholesterol as a building block for steroid hormones, including testosterone.
Having high LDL cholesterol does not mean that the body will make more testosterone.
Low testosterone and abnormal cholesterol may share causes such as obesity, diabetes, aging and certain medications.
Testosterone therapy can affect lipids, but the direction and size of the effect vary.
Statins may slightly lower total testosterone on average, but current evidence does not show that they usually cause clinical testosterone deficiency.

Why cholesterol matters for hormone production

Cholesterol is a waxy lipid that supports cell membranes, bile-acid production and steroid-hormone synthesis. Cells that make testosterone convert cholesterol through several biochemical steps. Most circulating cholesterol, however, is transported in lipoproteins and serves many functions beyond hormone production.

LDL and HDL are not different kinds of cholesterol. They are particles that carry cholesterol through the bloodstream. Persistently elevated LDL contributes to atherosclerotic cardiovascular disease risk, which is why cholesterol treatment focuses on a person’s overall risk rather than hormone production alone.

Does high cholesterol increase testosterone?

No. The fact that cholesterol is a precursor to testosterone does not mean that more LDL in the blood produces more testosterone. Hormone production is tightly regulated by signals from the hypothalamus, pituitary gland and testes. Enzymes, receptor signaling, health status and age matter more than simply having extra circulating cholesterol.

High LDL should not be viewed as beneficial for testosterone. Current cardiovascular guidelines continue to treat LDL reduction as a major strategy for lowering atherosclerotic risk.^[2]

Why low testosterone and abnormal cholesterol often overlap

Men with obesity, insulin resistance or type 2 diabetes are more likely to have both lower testosterone and an unfavorable lipid profile. This overlap can create the impression that one condition directly causes the other when both may reflect a broader metabolic pattern.

Possible shared contributors include:

Visceral obesity
Insulin resistance and diabetes
Sleep apnea and inadequate sleep
Reduced physical activity
Age and chronic illness
Certain medications

Improving diet quality, activity, sleep and weight may benefit both cardiovascular risk and testosterone regulation. Learn more in our guide to testosterone and fat loss.

How does testosterone therapy affect cholesterol?

Research does not support one universal lipid response. In a meta-analysis of randomized trials, testosterone modestly lowered total cholesterol overall, while effects on LDL were not significant. Higher-dose regimens were more likely to reduce HDL.^[3]

A more recent meta-analysis in men with late-onset hypogonadism found small improvements in total cholesterol alongside a small reduction in HDL.^[4] Differences in dose, delivery method, baseline testosterone, health status and study duration can all influence the result.

These averages do not make testosterone a lipid-lowering medication. A clinician should monitor cholesterol based on the patient’s cardiovascular risk and use established treatments when they are indicated.

Does TRT increase cardiovascular risk?

The relationship between testosterone therapy and cardiovascular events has been debated for years. The TRAVERSE trial enrolled 5,246 men with symptoms, two low fasting testosterone measurements and existing or high cardiovascular risk. Testosterone was noninferior to placebo for major cardiovascular events during the study, although atrial fibrillation, acute kidney injury and pulmonary embolism were more frequent with testosterone.^[5]

The result is reassuring for appropriately selected and monitored men with hypogonadism. It does not establish that testosterone prevents heart disease, and it does not apply to unsupervised use, bodybuilding doses or men without confirmed deficiency.

Do statins lower testosterone?

Because statins reduce cholesterol synthesis, researchers have examined whether they also reduce testosterone. A 2024 systematic review found a small average reduction in total testosterone. In randomized trials, the decrease was about 13 ng/dL and generally did not push levels below the normal range.^[6]

That evidence does not support stopping a statin because of a presumed testosterone effect. Statins have established cardiovascular benefits for the right patients. If symptoms of testosterone deficiency occur, they should be evaluated with properly timed testing rather than by changing cardiovascular medication without medical advice.

Can low cholesterol cause low testosterone?

Ordinary LDL lowering is not the same as depriving the body of the cholesterol needed to make hormones. Cells can synthesize cholesterol and regulate uptake. Extremely low cholesterol or serious illness may coexist with hormone changes, but a routine cholesterol result cannot diagnose testosterone deficiency.

What should be tested?

A lipid panel commonly includes total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides. Interpretation depends on age, diabetes, blood pressure, smoking, family history and existing cardiovascular disease.

Testosterone evaluation is separate. The Endocrine Society recommends diagnosing hypogonadism only when compatible symptoms are accompanied by unequivocally and consistently low levels, confirmed with a repeat morning fasting measurement.^[1]

Practical ways to support both cardiovascular and hormone health

Use a dietary pattern rich in vegetables, fruit, legumes, whole grains, nuts, fish and unsaturated fats.
Limit trans fat and reduce saturated fat when advised for LDL management.
Perform regular aerobic and resistance exercise.
Work toward a sustainable weight if excess body fat is contributing to risk.
Address sleep apnea, smoking, diabetes and high blood pressure.
Take statins or other lipid-lowering medication exactly as prescribed.

Supplements should not replace evidence-based cholesterol treatment. A product that supports general nutrition or exercise performance cannot claim to treat high cholesterol or hypogonadism.

Frequently asked questions

Does testosterone raise LDL?

Not consistently. Studies in hypogonadal men show variable LDL changes, and the response can depend on the dose, formulation and population. Monitoring is appropriate during treatment.

Can low testosterone cause high cholesterol?

Low testosterone and abnormal cholesterol often occur together, but shared metabolic factors may explain much of the association. One result should not be assumed to cause the other.

Should I stop my statin if my testosterone is low?

No. Do not stop or change a statin without the prescribing clinician. Evaluate symptoms and testosterone separately using guideline-based testing.

Will a testosterone booster improve cholesterol?

There is no reliable evidence that over-the-counter testosterone boosters treat high cholesterol or reduce cardiovascular events.

The bottom line

Cholesterol helps the body make testosterone, but their clinical relationship is complex. High LDL is not useful for testosterone production, low testosterone does not automatically explain an abnormal lipid panel, and testosterone therapy is not a cholesterol medication. Treat each issue according to established diagnostic and cardiovascular guidelines.
