Synthetic estrogens are man-made compounds designed to mimic the effects of natural estrogen, a hormone primarily produced in the ovaries. These substances are often used in various medical treatments, including hormone replacement therapy for menopausal symptoms and certain hormonal contraceptives. Common types of synthetic estrogens include ethinyl estradiol and mestranol. While they can effectively manage hormonal imbalances, their use may also come with potential side effects, such as an increased risk of blood clots and certain cancers. Therefore, medical supervision is essential when using these medications.
