Estradiol is the most important hormone in the estrogen group. It regulates the menstrual cycle, causes the follicles to mature and ensures that the mucous membrane in the uterus is prepared for implantation.
The estradiol value fluctuates greatly during the natural course of the cycle. A permanently elevated estradiol level above the normal range can lead to cycle disorders and increased water retention.
An estradiol value below the normal range in the different phases of the cycle indicates underactive ovaries.
