An Estradiol (E2) test measures the most potent and abundant form of estrogen in your body. Estradiol is primarily produced by the ovaries in women and in smaller amounts by the testes and adrenal glands in men.
What This Test Measures
Estradiol (E2):
The primary estrogen hormone responsible for development and maintenance of female reproductive tissues, bone health, cardiovascular protection, and brain function. In men, estradiol plays a role in bone health, libido, and brain function.
Reference Ranges
Ranges vary significantly by sex, age, and menstrual phase:
Premenopausal Women (varies by cycle phase):
• Follicular phase: 12.5-166 pg/mL
• Ovulation peak: 85-498 pg/mL
• Luteal phase: 43.8-211 pg/mL
Postmenopausal Women:
• Typically below 30 pg/mL
Men:
• 10-40 pg/mL (optimal range debated; too high or too low can cause symptoms)
Results should always be interpreted by a healthcare provider in context.
Who Should Consider This Test
Women:
• Evaluating irregular or absent menstrual periods
• Investigating symptoms of menopause (hot flashes, night sweats, vaginal dryness)
