What is Estradiol?
Estradiol (E2) is a type of estrogen hormone found in both males and females. In females, it regulates the menstrual cycle, fertility, and ovulation, and can indicate conditions like PCOS. In males, it influences libido, erectile function, and sperm production. Estradiol also affects bone health and brain function.
Understanding Estradiol Levels
Estradiol tests are recommended on day 3 of the menstrual cycle. Levels vary throughout the menstrual cycle and decline during menopause. In males, estradiol levels are low and stable.
Reference Ranges for Estradiol:
Normally Menstruating Females:
- Follicular phase: 10–180 pg/mL
- Mid-cycle peak: 100–300 pg/mL
- Luteal phase: 40–200 pg/mL
Postmenopausal Females: Less than 10 pg/mL
Males: 20–50 pg/mL
For postmenopausal females on hormone replacement therapy, an estradiol range between 50-100 pg/mL is typical.
Maintaining Optimal Estradiol Levels
- Diet: Eat foods rich in phytoestrogens and essential vitamins.
- Lifestyle: Reduce body fat, manage stress, and avoid alcohol.
- Supplements: Consider black cohosh, DHEA, and red clover for low estradiol.
