Have scientists got nothing better to do but to just make stories up about meaningless crap like this?

[edit] Steroidal
The three major naturally occurring estrogens in women are estradiol, estriol, and estrone. In the body these are all produced from androgens through actions of enzymes.
From menarche to menopause the primary estrogen is 17β-estradiol. In postmenopausal women more estrone is present than estradiol.
Estradiol is produced from testosterone and estrone from androstenedione.
Estrone is weaker than estradiol.
