What are the estrogen drugs?
Natural estrogen: Basic natural estrogen secreted by the body, including estradiol (E2), estrone (E0) and estriol (E3). They are closely related to the metabolic process in the body and the development and maintenance of secondary sexual characteristics.
Semi-synthetic estrogen: drugs with estrogenic activity, such as ethinylestradiol and nilestriol, are synthesized by artificial methods, and some groups are lost or added to the basic structure of steroid hormones.
Synthetic estrogen: Also known as non-steroidal estrogen. The basic structure of these drugs is not the framework structure of steroids, but they have estrogenic activity, such as diethylstilbestrol.
Excessive use is inappropriate and will have side effects.
