Let's clear something up: estrogen isn't just a 'women's hormone.' Men produce it as well, and it matters for both. Estradiol (E2) is the most active form, and it influences everything from your liver and bones to your nervous system and immune defence. When estrogen levels drift too high or too low, the effects ripple across your entire body. Testing gives you the full picture.
Estrogen testing is key if you're going through fertility treatment, managing menopause, tracking ovarian function, or just trying to understand irregular periods. Lifestyle and diet have a huge impact on estrogen balance, so regular monitoring can show you whether the changes you're making are actually working.
What a high value can mean
High estrogen can be driven by PCOS, thyroid disorders, obesity, certain medications (HRT, birth control), liver issues, or estrogen-secreting tumours. Classic signs: weight gain around hips and thighs, menstrual irregularities, breast tenderness, mood swings, headaches, fatigue, bloating, and hair thinning.
What a low value can mean
Low estrogen can bring irregular or missing periods, hot flashes, night sweats, mood shifts, depression, fatigue, vaginal dryness, painful sex, lower libido, and bone density loss. It's common during menopause but can also result from over-exercising or eating disorders.
Wait two days after applying an estrogen patch, or two to four hours after taking oral estrogen or applying estrogen gel, before taking this test. Bring valid ID. If you take a supplement containing biotin (often sold for hair and nails), pause it for two days before the test, as high doses can distort the result.

For fertility purposes, estrogen is usually tested on day 3 of your cycle. Your healthcare provider will advise on the best timing for your situation.
Absolutely. Men produce small amounts of estrogen. Too much can cause breast tissue growth, weight gain, and mood changes. Too little can weaken bones.
Yes. Fat tissue actually produces estrogen, so carrying extra weight can push levels up in both men and women.
