     Medical uses   Oestrogens or estrogens (see spelling differences) are a group of compounds named for their importance in both menstrual and estrous reproductive cycles. They are the primary female sex hormones. Natural estrogens are steroid hormones, while some synthetic ones are non-steroidal. The name comes from the Greek oistros, literally meaning "verve or inspiration" but figuratively sexual passion or desire, and the suffix -gen, meaning " producer of".Estrogens are synthesized in all vertebrates as well as some insects. Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history.
