Estradiol (e2)

Estradiol, Serum test evaluation measures the level of estradiol, one of the main forms of estrogen in the body. It plays an essential role in the development of female reproductive tissues, regulation of the menstrual cycle, bone health, and maintenance of secondary sexual characteristics. Although most prominent in women, this hormone is also present in men, where it supports sperm production and bone density. Monitoring its concentration provides valuable insights into reproductive health, fertility, and overall hormonal balance.

Why consider Estradiol, Serum test?

Abnormal levels can influence fertility, menstrual regularity, and bone strength. Lower values may suggest ovarian insufficiency, menopause, or certain pituitary disorders, while higher values may point to conditions such as polycystic ovary syndrome, ovarian tumors, or liver problems. This evaluation is also commonly used in fertility treatments to track ovarian response to medication. In men, abnormal levels may indicate testicular or hormonal imbalance issues.

Who should get Estradiol, Serum test done?

It may be recommended for:

• Women experiencing irregular menstrual cycles or infertility

• Patients undergoing assisted reproductive treatments such as IVF

• Individuals with symptoms suggesting hormonal imbalance, such as hot flashes or osteoporosis

• Men being assessed for low sperm count or suspected estrogen imbalance

• Patients with suspected ovarian or pituitary gland disorders

For individuals undergoing fertility therapy, repeated measurements provide guidance on treatment progress.
