The levels of hormones released change on a daily basis. Estrogen and testosterone are released in short bursts. They change right down to the very minute.
Estrogen is an entire class of hormones:
Estradiol is the primary sex hormone in women. The developing ovarian follicles are responsible for production. Female characteristics and sexual functioning can be attributed to this. Estradiol holds responsibility for problems such as endometriosis, female cancers and fibroids.
During pregnancy the placenta produces Estriol. Estriol, weaker of the three estrogens, can be used to access fetal health and wellbeing.
Estrone is the least abundant of the three estrogens. This estrogen is almost always in reproductive women. This estrogen is crucial to health and disease. Estrone is widespread throughout the body, it is produced in the adrenal glands and with in fat and muscles cells. It is the most predominant estrogen in menopausal women.
