Oestradiol or estradiol, also referred to as the “hormone of female beauty”, is the primary female hormone. Along with other oestrogens, oestradiol is involved in sexual development and regulation of the female reproductive cycle. Besides regulating the menstrual cycle, it helps maintain a balanced emotional state and contributes to soft skin, bright eyes and strong hair and bones. Oestradiol deficiency, which may often be caused by prolonged stress, can cause mood disorders, hot flashes, sleep disorder, loss of bone density (osteoporosis) and memory disorders.
