Estradiol a type of the hormone estrogen is produced by the follicle as it grows and levels go up quickly just before ovulation.
If fertility medicines are being used to cause a woman to ovulate, estradiol levels are checked more often to keep an eye on the growth of the follicle, but it is not used to tell you when you might ovulate.
