passage: 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?
Yes

passage: The team made its first Super Bowl appearance in Super Bowl VI, losing to the Dallas Cowboys, 24--3. The following year, the Dolphins completed the NFL's only perfect season, culminating in a Super Bowl win, winning all 14 of their regular season games, and all three of their playoff games, including Super Bowl VII. The 1972 Dolphins were the third NFL team to accomplish a perfect regular season, and won Super Bowl VIII, becoming the first team to appear in three consecutive Super Bowls, and the second team (the first AFL/AFC team) to win back-to-back championships. Miami also appeared in Super Bowl XVII and Super Bowl XIX, losing both games.

Yes
