We underestimate the risks of synthetic hormones
significantly by ignoring the vast reach hormones have

Editor's Notes
In much the same way that mind body dualism has pervaded medical thinking
This compartmentalized approach to contraception and indeed reproduction has pervaded women’s health research for decades.
We need to disabuse ourselves of the notion that the reproductive organs can somehow be separated from the totality of women’s health.
The reproductive organs are no more separate and no less important than other organs within the human body.
The health of these organs, the health of the hormones that impact these organs is connected to all of health.
So while we have successfully figured out that when we override endogenous hormone production in the female ovary and subsequently eliminate ovulation and prevent pregnancy, we shouldn’t be so naïve to think that this action is limited solely to it’s target tissue – the ovary. No, far from it.
By the 1940s scientists had figured out the importance of hormones in the female reproductive cycle. They established that once a woman becomes pregnant, her fertility is suspended. A woman cannot conceive again while pregnant, because her ovaries secrete the hormones estrogen and progesterone. The secretion of estrogen tells the pituitary gland to withhold the hormones necessary for ovulation. The secretion of progesterone also helps to inhibit ovulation by suppressing the lutenizing hormone known as LH.

I want to take you on a trip that goes beyond reproduction b/c steroid hormones regulate everything.
Just to give you and idea about the breadth and depth of steroid influence, did you know that they can synthesized in other tissues – like the brain.
And if they can be synthesized in these other tissues, doesn’t it make sense that they might perform a function there as well. And so, from here we can see the distribution of the two primary types of estrogen receptor, Era and ERB, notice they are all over the body and the brain suggesting that when we manipulate these hormones or there balance is disrupted in any way, there will be broad based effects. And this is just the estrogen receptors, there are similar distributions for the progesterone receptors, the androgen receptors, the glucocorticoids and mineralocorticoids.
Steroid hormones and their receptors are distributed throughout the brain and body
http://iovs.arvojournals.org/article.aspx?articleid=2122996
Once upon a time, not too long ago, and even today, the notion of one-ligand > one receptor, single lock/single key pervaded. We now know that is not true. While there are specific estrogen, androgen, glucocorticoid and mineralocorticoid receptors that preferentially bind to their cognate ligand, it’s not that simple. Everything crossbinds. Progesterone has a very high affinity of mineralocorticoid and glucocorticoid receptors, for example. And depending upon the balance of power – one’s internal chemistry – can evoke changes consistent with aldosterone or cortisol binding.
And they don’t need their own receptors, they can cross bind.
adrenaline
Lupron, ovary removal, etc.
Imagine if there were no options or if you had to respond to each and every stressful event in your life using exactly the same behaviors or response patterns. You would not get very far. The same holds true for cell behavior, and more specifically, mitochondrial behavior. The mitochondria need options to respond to the differing needs of the cells that they supply with energy. If those options become limited in any way, the mitochondria become less effective. They produce less energy, scavenge fewer oxidants (toxicants) and when stressors present, cannot easily adapt. In fact, the more inflexible the mitochondria are forced to become, the less likely they, and the cells, tissues, organs, and organism within which they reside, will survive.
Estradiol upregulates the expression of the enzymes that make up the PDC (in the brain). If estradiol is reduced or blocked, mitochondrial ATP production will take a hit. If estradiol is blocked in an already nutrient depleted woman, the first step in mitochondrial fuel conversion would take a double hit.
I’ve written about this research previously, not fully understanding the implications. Estradiol allows cardiomyocytes (heart cells) to switch from their preferred fuel of fatty acids to glucose during stressors such as heart attack (and theoretically during any stressor like exercise). That ability to switch fuel types is protective and allows the cells to survive and heal. It may explain why women are more susceptible to heart damage post menopause, when endogenous estradiol declines. This may also point to a pathway for post oophorectomy and post Lupron declines in normal heart function.

BPA research --
Aromatase activity is negligible in the ectopic endometrium, whereas the activity of estrogen sulfatase is high though not different between ectopic, eutopic and control endometrium. The activity of 17β-hydroxysteroid dehydrogenases (17β-HSDs) converting estrone into 17β-estradiol is higher in the ectopic compared to the eutopic endometrium in patients. The activity of 17β-HSDs converting 17β-estradiol back to estrone is significantly lower in the ectopic compared to the eutopic endometrium of both patients and controls. To evaluate the net metabolic capacity of tissues to synthesize 17β-estradiol, we calculated the activity ratio between 17β-HSDs synthesizing versus 17β-HSDs inactivating 17β-estradiol. This ratio is significantly higher in the ectopic compared to the eutopic endometrium of patients and controls, indicating a high synthesis of 17β-estradiol in the ectopic locations. This is further supported by the elevated mRNA levels of the estrogen-responsive gene TFF1in all ectopic compared to eutopic endometria.
Conclusion: Endometriotic lesions have higher production of 17β-estradiol than the eutopic endometrium of patients and controls. This is mostly the result of impaired metabolism.
Endometriosis lesions have increased activity of 17β-hydroxysteroid dehydrogenases synthesizing active 17β-estradiol compared to the eutopic endometrium.
