enzymologist started getting the same isotopes that he had had and showed that in fact the old 1940s research was exactly what's happening and now everyone knows that estrogen, estradiol and estrone are perfectly interchangeable and that's exactly where progesterone and thyroid and stress hormones interact with estrogen. Progesterone turns off some of the enzymes that activate estrogen and activate enzymes that inactivate estrogen so the enzyme approach opens up the whole issue of environmental physiology, nutritional, metabolic effects on the estrogen system and estrogen's deranging effects on all of those systems so that's all now coming back but 50 years of belief in a genetic explanation of why estrogen is so good for females and harmless to everyone else.
