What's the difference between sensitive and standard estradiol?

Sensitive uses mass spectrometry, accurate down to male-range concentrations. Standard immunoassay is built for female ranges and unreliable in men.

How do you lower high estradiol naturally?

Lose body fat (aromatase lives in fat tissue), cut alcohol, address insulin resistance. Medication (anastrozole) only if lifestyle hasn't moved it and symptoms persist.

Estradiol (Sensitive) (E2)

Estradiol is the active oestrogen in men, made primarily by aromatising testosterone in fat tissue. Use the sensitive (LC-MS/MS) assay — the standard immunoassay is unreliable at male concentrations. Too high causes gyno, water retention, mood issues; too low crashes libido and bone density.

Category: Hormones
Units: pmol/L
Reference range: 60-150 pmol/L (men, sensitive assay)

What does a high Estradiol (Sensitive) result mean?

Above 150 pmol/L: obesity, alcohol, TRT without monitoring, rare aromatase-secreting tumours.

What does a low Estradiol (Sensitive) result mean?

Below 60 pmol/L: aggressive aromatase inhibitor use, low body fat, low testosterone. Causes joint pain, low libido, bone loss long-term.

Why does Estradiol (Sensitive) matter?

The T:E2 ratio matters more than either number alone. Men need oestradiol — it's not the enemy. The goal is appropriate range, not zero.
