Ovulation blood level estradiol

Estradiol is a hormone that promotes ovarian development and egg development in women. It also works by regulating a woman's menstrual cycle and fertility. Estradiol levels change during a woman's menstrual cycle, especially during ovulation.

Doctors usually take a blood sample to test estradiol levels in the middle of a woman's menstrual cycle, when she is ovulating. By testing estradiol levels, doctors can learn about a woman's egg production and ovulation, as well as whether there are problems such as decreased fertility.

In addition to testing estradiol levels, doctors can use other indicators to assess a woman's health. For example, doctors can assess a woman's fertility by checking chromosomes in a blood sample, or assess a woman's health by checking blood samples for other indicators, such as thyroid hormone and insulin.
