High levels of estradiol indicate that you might have a problem with your ovarian reserve. It could also mean that the estradiol is suppressing FSH.
Either of these things could mean that you will have more trouble getting pregnant, more trouble ovulating even with treatment , and reduced success with IVF.
In rare cases, high levels of estradiol could indicate an ovarian tumor or hyperthyroidism. Women with eating disorders or who practice extreme endurance exercising may have low levels of estradiol. After menopause, estradiol levels are also low. Estrogen pills, patches, suppositories, and even injections can be prescribed to support fertility treatments.
In patients with a thin endometrial lining, estrogen can be used to support growth and development and promote receptivity. Anti-mullerian hormone AMH plays a role in choosing which follicle will become the dominant follicle, which will release an egg at ovulation. The dominant follicle begins producing estradiol. Estradiol levels rise gradually at first, and then sharply rise two to three days before ovulation. Estradiol levels peak just before a surge of two other important hormones—luteinizing hormone LH and follicle stimulating hormone FSH —triggers ovulation.
Estradiol levels decline during the ovulation phase, which lasts about 16 to 32 hours. A specialized group of cells forms from the ruptured follicle, and secretes the hormone progesterone in order to prepare the uterus for potential implantation of a fertilized egg cell. After their decline during ovulation, estradiol levels gradually start to increase again during the luteal phase, peaking and then dropping off to another low before the onset of the next menstrual cycle.
As estradiol levels fall, levels of progesterone another important hormone fall as well. FSH levels begin to rise again at the end of the luteal phase, preparing to stimulate another ovarian follicle and start the menstrual cycle over again.
Hormone levels during pregnancy If an egg cell is successfully fertilized during the ovulation phase of the menstrual cycle, and successfully implants in the uterus, a pregnancy results.
Hormone levels during menopause When a woman reaches menopause, her hormone levels will again change, potentially resulting in menopausal symptoms. Related content How do you boost fertility?

More about egg quality, egg quantity and fertility problems Day 3 estradiol testing A blood estradiol level on day 3 we do it on any day between days 2 and 4 of the menstrual cycle is a way to potentially discover some of those women with a normal day 3 FSH that may in fact have decreased egg quantity and quality.
