    Is summing estradiol, estrone, and estriol the right way to calculate total estrogen levels in serum?

    I was looking at some old estrogen tests I had done, and noticed the the total estrogens doesn't match with the sum of estradiol and estrone, even if they are measured in the same units. Does anyone know if the total estrogens is supposed to be the arithmetic sum of estradiol, estrone, and...

    Not a "male" hormone - testosterone (T) beneficial for female heart health

    It always feels good to read an article on a scientific discovery and have one of the authors put on his Peat-y hat and quote Peat directly. I am joking, of course, but the study below and the statements from its lead author do sound like Peat had a significant participation in the study...

    Estrogens cause obesity / PCOS in women, DHT is protective

    Female obesity and the closely related condition PCOS are perhaps the female equivalent of the so-called "androgen hypothesis" for balding and prostate cancer in men, as the female version of this hypothesis not only blames androgens for these conditions but specifically singles out DHT as the...

    Lowering Estrogen Prevents Memory Decline In Menopausal Females

    As many of my readers know, the WHI studies were highly detrimental to the profits of the estrogen industry. Every since the results of those studies came out, the estrogen industry has been trying to undermine the findings and re-introduce estrogen HRT for women with the claims that estrogen is...

    While Estradiol Falls, Estrone Rises With Age And Is Much More Relevant For Estrogen-driven Diseases

    I posted a few studies in the past demonstrating that estrone (E1) and especially its long-lasting derivative estrone sulfate (E1S) are reliable biomarkers of both breast and prostate cancer progression/prognosis. However, for some reason the medical industry is obsessed with estradiol and since...

    Estrogen Excess During Pregnancy May Cause Autism

    Finally! Some common sense is emerging from the medical profession. For one, it points the finger straight at estrogen as a possible cause of autism. And not just estradiol, which the medical profession considers the only estrogen of note, but all 3 of them (estrone, estradiol, estriol). So, all...

    Niacinamide And Methylene Blue Increase Estrogen Deactivation (by Liver)

    There is an old study often cited by Peat in regards to liver health and estrogen. That study found that vitamins B1 (thiamine) and B2 (riboflavin) are crucial for the deactivation/metabolism of estrogen by the liver. Vitamins B1 & B2 Are Required For Estrogen Inactivation By Liver The study...

    Pregnenolone Is A (functional) Estrogen Antagonist

    About 2 years ago I posted a thread on the antagonism of pregnenolone to estrogen. Pregnenolone Is An Estrogen Antagonist That claim was from a study, which itself referenced an old French study from 1950. I asked @burtlancast to find it and he was able to trace it to a hardcopy of the French...

    Estrogen+PUFA Esters May Drive Obesity; Most Doctors Have Not Even Heard Of Them

    An unassailable dogma in endocrinology is that menopause is characterized by low estrogen levels. The fact that plasma levels are only indicative of ovarian activity is conveniently overlooked, as is the fact that fat tissue grows after menopause and fat is the primary source of estrone (estrone...

    Unsaturation = Estrogenic, Saturation = Androgenic

    Most people on the forum have read Peat's articles on PUFA and its great synergism with the estrogenic hormones. Peat has written that saturated fats have effects opposite to those of PUFA and there are studies showing feeding saturated fat increases androgen synthesis. I have been researching...

    Androsterone - A Potent Steroidal Aromatase Inhibitor

    It is well-known in medical circles (at least in doctors over 50) that some androgens like DHT are potent aromatase inhibitors (AI). In fact, before the advent of modern AI drugs like letrozole, anastrozole and fadrozole the 5-AR androgens were a mainstream therapy for estrogen-receptor-positive...

    Aspirin Lowers Estrogen Levels / Load / Burden

However, studies showing direct effects of aspirin on estrogenic burden / load in humans are lacking. Speaking of estrogenic burden / load, as I mentioned in...

    Pregnenolone Is An Estrogen Antagonist

    Alzheimer Patients Have "aged" Adrenals, Higher Cortisol And Estrone

    The study also found correlation with testosterone, but the link was not consistent across the different measurement methods, while it was for estradiol and estrone. Nonetheless, it underscores Peat's recent statement that to him testosterone was almost as dangerous a hormone as estrogen...
