Passage: Estrogen -- 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. The three major naturally occurring forms of estrogen in females are estrone (E1), estradiol (E2), and estriol (E3). Another type of estrogen called estetrol (E4) is produced only during pregnancy. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males compared to females, estrogens nevertheless also have important physiological roles in males.
Question: is there such a thing as natural estrogen

Passage: Special Forces (United States Army) -- The United States Army Special Forces, colloquially known as the Green Berets due to their distinctive service headgear, are a special operations force tasked with five primary missions: unconventional warfare (the original and most important mission of Special Forces), foreign internal defense, special reconnaissance, direct action, and counter-terrorism. The first two emphasize language, cultural, and training skills in working with foreign troops. Other duties include combat search and rescue (CSAR), counter-narcotics, counter-proliferation, hostage rescue, humanitarian assistance, humanitarian demining, information operations, peacekeeping, psychological operations, security assistance, and manhunts; other components of the United States Special Operations Command (USSOCOM) or other U.S. government activities may also specialize in these secondary areas. Many of their operational techniques are classified, but some nonfiction works and doctrinal manuals are available.
