Estrogen is one of the key sex hormones that plays an important role in female sexual development and function. When we think of estrogen, we usually think of estradiol, which is the primary estrogen produced naturally in the ovaries.
What Does Estrogen Do?
Estrogen has many important functions in the female body including:
- Regulating the menstrual cycle and supporting reproduction
- Maintaining the health of tissues like the vagina, uterus, and breasts
- Supporting bone strength and cardiovascular health
- Regulating mood, cognition, and behavior
"Estrogen helps make us women and shapes many aspects of our health and wellbeing," says Dr. Sarah Kim from
Balance Hormone Clinic.
When Does Estrogen Production Begin and End?
Estrogen production begins during
puberty and rises each month to trigger
ovulation. After ovulation, estrogen levels fall until menstruation occurs. This cycle repeats until
menopause generally between ages 45-55. At menopause, the ovaries stop releasing eggs and estrogen levels decline permanently.
Some women experience more significant
estrogen deficiency during the menopausal transition causing symptoms like hot flashes, vaginal dryness, sleep disruption, and mood changes. Hormone therapy can provide relief by restoring estrogen levels.
Should I Get My Estrogen Levels Checked?
Getting your estrogen levels tested can be helpful to evaluate:
- Delayed or absent puberty
- Irregular or heavy periods
- Infertility or repeat miscarriages
- Postmenopausal symptoms
- Low libido or vaginal dryness
