Etymology

The term 'estradiol' is derived from the chemical nomenclature of estrogens, which are a group of steroid hormones. The prefix 'estr-' is derived from the word 'oestrus,' referring to the period of heightened sexual receptivity in female mammals, while 'diol' indicates the presence of two hydroxyl (–OH) groups in its molecular structure. Estradiol was first isolated from the urine of pregnant women in the 1920s and subsequently synthesized in laboratories. Over the years, its role in women's health, particularly in relation to menstruation, menopause, and hormone replacement therapies, has become a significant area of research. The understanding of estradiol's functions has evolved, highlighting its broader impacts on cardiovascular health, bone density, and mental well-being.
