Doctor's Assessment Included

Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.

Hormones

Estradiol (E2)

Estradiol (E2) is the primary estrogen in men, influencing bone density, libido, and cardiovascular health. While often associated with women, balanced estradiol levels are essential for men's wellbeing. Your healthcare provider can help interpret your results.

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

What It Measures

This test measures the concentration of estradiol (E2) in your blood. Estradiol is produced primarily by the ovaries in women and in smaller amounts by the testes and adrenal glands in men. Your healthcare provider may use this result alongside other hormone levels.

Why It Matters

In men, estradiol supports bone mineral density, brain function, and cardiovascular protection. Imbalanced levels could suggest issues with testosterone conversion or other hormonal concerns. Consulting your healthcare provider may help identify whether further evaluation is appropriate.

When to Test

Your healthcare provider may recommend testing estradiol when investigating irregular menstrual cycles, fertility concerns, menopausal symptoms, or unexplained mood changes. For men, testing could be suggested when evaluating gynecomastia or other hormonal concerns. Consult your provider for personalised timing advice.

Symptoms

Low Levels

Some people may experience hot flashes, night sweats, mood changes, vaginal dryness, or decreased bone density when estradiol levels are low. Fatigue and difficulty concentrating could also suggest reduced estradiol. A healthcare provider can help determine the cause and recommend appropriate support.

High Levels

Elevated estradiol levels may be associated with bloating, breast tenderness, mood swings, or irregular periods in women. In men, high levels could suggest gynaecomastia or reduced libido. Your healthcare provider can evaluate whether further investigation is needed based on your symptoms.

Recommendations

Male

If Low

Low estradiol in men may indicate hypogonadism or pituitary dysfunction. Consider consulting an endocrinologist for evaluation and possible testosterone replacement therapy.

If High

Elevated estradiol in men may indicate obesity, liver disease, or use of certain medications. Consider weight management, liver function tests, and medication review.

Lifestyle Tips

Maintaining a healthy weight, regular physical activity, and a balanced diet rich in fibre and cruciferous vegetables may support healthy estrogen metabolism. Limiting alcohol intake and managing stress could also contribute to hormonal balance. Always discuss lifestyle changes with your healthcare provider.
