Oestradiol (OEST)

Oestradiol (OEST) is the most potent and predominant form of estrogen, a key sex hormone in women. It is primarily produced in the ovaries, but also in smaller amounts by the adrenal glands and, in men, the testes. Oestradiol plays a critical role in the regulation of the menstrual cycle and is essential for the development of secondary sexual characteristics, such as breast development and the regulation of the reproductive system.

 

Beyond its role in reproduction, oestradiol has significant effects on other systems, including bone health, cardiovascular function, and skin elasticity. It helps maintain bone density by preventing bone resorption and has protective effects on the cardiovascular system by influencing cholesterol levels and blood vessel function.

 

Fluctuations in oestradiol levels can lead to various conditions, such as premenstrual syndrome (PMS), menopausal symptoms, and osteoporosis. Monitoring and managing oestradiol levels is important for overall health, particularly during menopause.
