Estrogens are a group of hormones that are predominantly produced by the female reproductive system. These hormones play a vital role in regulating the menstrual cycle, supporting pregnancy, and maintaining bone health. They are also associated with physical and emotional changes during puberty and menopause. Synonyms for estrogens include estradiol, estriol, and estrone. These hormones can also be found in certain foods like soy products and flaxseed. Estrogens are often prescribed as hormone replacement therapy to alleviate symptoms of menopause and are also used to treat conditions like osteoporosis, breast and prostate cancer, and infertility. It is important to consult with a healthcare provider before taking any form of hormone therapy.
