Estradiol

Overview

Basic Info

SummaryEstradiol (E2), a predominant female sex hormone and a member of the estrogen family, is responsible for regulating the menstrual and estrous cycles. It plays a pivotal role in orchestrating the development of female secondary sexual characteristics such as breast growth, widening of the hips, and a characteristic fat distribution pattern, as well as the development and sustenance of female reproductive tissues such as the mammary glands, uterus, and vagina. Apart from these crucial functions, E2 exerts significant effects on various other tissues in the body, including the liver, bone, fat, skin, and the brain. Estradiol activates both subtypes of the estrogen receptor (ERα and ERβ), is considered a potent agonist of these nuclear steroid hormone receptors. The hormone has multiple clinical applications, such as treating menopause symptoms, preventing osteoporosis in menopausal women, and treating low estrogen levels in women with ovarian failure. Moreover, it is also indicated in the treatment of certain types of breast and prostate cancer, which highlights its versatility and clinical significance. Interestingly, E2 is available in a diverse range of forms including oral tablets, topical gels or patches, vaginal creams, and injections, which provide ample options for individuals to choose from, based on their unique and specific requirements, preferences, and medical history.
