  9. A review of the use of estrogens reported in J.A.M.A. (only up to 1987) found nearly 200 different
  10. "indications" for its use. (Palmlund, 1996.) Using the conservative language of that journal, such use
  11. could be said to constitute wildly irresponsible "empirical" medical practice. More appropriate language
  12. could be used.
  13. </p>

  15. Pollution of the environment and food supply by estrogenic chemicals is getting increased attention.
  16. Early in the study of estrogens, it was noticed that soot, containing polycyclic aromatic hydrocarbons,
  17. was both estrogenic and carcinogenic. Since then, it has been found that phenolics and chlorinated
  18. hydrocarbons are significantly estrogenic, and that many estrogenic herbicides, pesticides, and
  19. industrial by-products persist in the environment, causing infertility, deformed reproductive organs,
  20. tumors, and other biological defects, including immunodeficiency. In the Columbia River, a recent study
  21. found that about 25% of the otters and muskrats were anatomically deformed.
  22. </p>
  23. <p>
  24. Estrogenic pollution kills birds, panthers, alligators, old men, young women, fish, seals, babies, and
  25. ecosystems. Some of these chemicals are sprayed on forests by the US Department of Agriculture, where
  26. they enter lakes, underwater aquifers, rivers, and oceans. Private businesses spray them on farms and
  27. orchards, or put them into the air as smoke or vapors, or dump them directly into rivers. Homeowners put
  28. them on their lawns and gardens.
  29. </p>
  30. <p>
  31. Natural estrogens, from human urine, enter the rivers from sewage. Many tons of synthetic and
  32. pharmaceutical estrogens, administered to menopausal women in quantities much larger than their bodies
  33. ever produced metabolically, are being added to the rivers.
  34. </p>
  35. <p>
  36. In the same way that weak estrogens in the environment may become hundreds of times more estrogenic by
  37. synergistic interactions (J. A. McLachlan, et al., <em>Science,</em> June 7, 1996), combinations of
  38. natural, medical, dietary, and environmental estrogens are almost certain to have unexpected results.
  39. The concept of a "protective estrogen" is very similar to the idea of "protective mutagens" or
  40. "protective carcinogens," though <em>in the case of estrogens, their promoters don't even know what the
  41. normal, natural functions of estrogen are.
  42. </em>

  45. In November, 1995, an international conference was held to study the problem of "Environmental
  46. endocrine-disrupting chemicals," and to devise strategies for increasing public awareness of the
  47. seriousness of the problem. Their "Statement from the work session" says "New evidence is especially
  48. worrisome because it underscores the exquisite sensitivity of the developing nervous system to chemical
  49. perturbations that result in functional abnormalities." "This work session was convened because of the
  50. growing concern that failure to confront the problem could have major economic and societal
  51. implications." <strong>"We are certain of the following: Endocrine-disrupting chemicals can undermine
  52. neurological and behavioral development and subsequent potential of individuals...."</strong>
  53. "Because the endocrine system is sensitive to perturbation, it is a likely target for disturbance."
  54. "Man-made endocrine-disrupting chemicals range across all continents and oceans. They are found in
  55. native populations from the Arctic to the tropics, and, because of their persistence in the body, can be
  56. passed from generation to generation." <strong>"...many endocrine-disrupting contaminants, even if less
  57. potent than the natural products, are present in living tissue at concentrations millions of times
  58. higher than the natural hormones."</strong> "The developing brain exhibits specific and often narrow
  59. windows during which exposure to endocrine disruptors can produce permanent changes in its structure and
  60. function."
  61. </p>
  62. <p>
  63. In spite of this increased exposure to estrogens, there is a new wave of advertising of estrogenic
  64. substances, based on the idea that weak estrogens will provide protection against strong estrogens. The
  65. environmental background of estrogenic pollution already provides a continuous estrogenic exposure. In
  66. the 1940s, Alexander Lipshuts demonstrated that a continuous, weak estrogenic stimulus was immensely
  67. effective in producing, first fibromas, then cancer, in one organ after another, and the effect was not
  68. limited to the reproductive system. How is it possible that the idea of "protection" from a weak
  69. estrogen seems convincing to so many? Isn't this the same process that we saw when the nuclear industry
  70. promoted Luckey's doctrine of "radiation hormesis," literally the claim that "a little radiation is
  71. positively good for us"?
  72. </p>
  73. <p>
  74. DES (diethyl stilbestrol) is one of the most notorious estrogens, because studies in humans revealed
  75. that its use during pregnancy not only caused cancer, miscarriages, blood clots, etc., in the women who
  76. used it, but also caused cancer, infertility, and deformities in their children, and even in their
  77. grandchildren. (But those transgenerational effects are not unique to it.)
  78. </p>
  79. <p>
  80. Besides the absurd use of DES to prevent miscarriages, around 1950 it was also used to treat
  81. vulvovaginitis in little girls, for menstrual irregularity at puberty, to treat sterility, dysfunctional
  82. bleeding, endometriosis, amenorrhea, oligomenorrhea, dysmenorrhea, migraine headaches, nausea and
  83. vomiting, and painful breast engorgement or severe bleeding after childbirth.
  84. </p>
  85. <p>
  86. DES is a "weak" estrogen, in the sense that it doesn't compete with natural estrogens for the "estrogen
  87. receptors." (Estriol binds more strongly to receptors than DES does: "Cytosolic and nuclear estrogen
  88. receptors in the genital tract of the rhesus monkey," J. Steroid Bioch. 8(2), 151-155, 1977.) Pills
  89. formerly contained from 5 to 250 mg. of DES. The 1984 <em>PDR</em> lists doses for hypogonadism and
  90. ovarian failure as 0.2 to 0.5 mg. daily. In general, dosage of estrogens decreased by a factor of 100
  91. after the 1960s.
  92. </p>
  93. <p>
  94. An aggressively stupid editorial by Alvin H. Follingstad, from the Jan. 2, 1978, issue of JAMA, pages
  95. 29-30, "Estriol, the forgotten estrogen?" is being circulated to promote the use of estriol, or the
  96. phytoestrogens. It argues that women who secrete larger amounts of estriol are resistant to cancer.
  97. </p>
  98. <p>By some tests, estriol is a "weak estrogen," by others it is a powerful estrogen.</p>
  99. <p>
  100. When estriol was placed in the uterus of a rabbit, only 1.25 mcg. was sufficient to prevent implantation
  101. and destroy the blastocyst. (Dmowski, et al., 1977.) Since the effect was local, the body weight of the
  102. animal doesn't make much difference, when thinking about the probable effect of a similar local
  103. contentration of the hormone on human tissues. The anti-progestational activity of estriol and estradiol
  104. are approximately the same. (Tamotsu and Pincus, 1958.)
  105. </p>
  106. <p>
  107. When 5 mg. of estriol was given to women intravaginally, this very large dose suppressed LH within 2
  108. hours, and suppressed FSH in 5 hours. Given orally, 8 mg. had similar effects on LH and FSH after 30
  109. days, and also had an estrogenic effect on the vaginal epithelium.. These quick systemic effects of a
  110. "weak estrogen" are essentially those of a strong estrogen, except for the size of the dose. (Schiff, et
  111. al., 1978.)
  112. </p>
  113. <p>When administered subcutaneously, estriol induced abortions and stillbirths (Velardo, et al.)</p>
  114. <p>
  115. Another indication of the strength of an estrogen is its ability to cause the uterus to enlarge. Estriol
  116. is slightly weaker, in terms of milligrams required to cause a certain rate of uterine enlargement, than
  117. estradiol. (Clark, et al., 1979.) But isn't the important question whether or not the weak estrogen
  118. imitates all of the effects of estradiol, including carcinogenesis and blood clotting, in addition to
  119. any special harmful effects it might have?
  120. </p>
  121. <p>
  122. When added to long-term culture of human breast cancer cells, estriol stimulated their growth, and
  123. overcame the antiestrogenic effects of tamoxifen, even at concentrations hundreds of times lower than
  124. that of tamoxifen. "The data do not support an antiestrogenic role for estriol in human breast cancer."
  125. (Lippman, et al., 1977.)
  126. </p>
  127. <p>
  128. Studies of the urinary output of estriol/estradiol in women with or without breast cancer do not
  129. reliably show the claimed association between low estriol/estradiol and cancer, and the stimulating
  130. effect of estriol on the growth of cancer cells suggests that any alteration of the estrogen ratio is
  131. likely to be a <em>consequence</em> of the disease, rather than a cause. The conversion of estradiol to
  132. other estrogens occurs mainly in the liver, in the non-pregnant woman, as does the further metabolism of
  133. the estrogens into glucuronides and sulfates. The hormonal conditions leading to and associated with
  134. breast cancer all affect the liver and its metabolic systems. The hydroxylating enzymes are also
  135. affected by toxins. Hypothyroidism (low T3), low progesterone, pregnenolone, DHEA, etiocholanolone, and
  136. high prolactin, growth hormone, and cortisol are associated with the chronic high estrogen and breast
  137. cancer physiologies, and modify the liver's regulatory ability.
  138. </p>
  139. <p>
  140. The decreased output of hormones when the fetal-placental system is dying is a natural consequence,
  141. since the placenta produces hormones, and during pregnancy converts estradiol to estriol. Since
  142. estradiol in excess kills the fetus, its conversion by the placenta to estriol is in accord with the
  143. evidence showing that estriol is the more quickly excreted form. (G. S. Rao, 1973.) The conversion of
  144. 16-hydroxy androstenedione and 16-hydroxy-DHEA into estriol by the placenta (Vega Ramos, 1973) would
  145. also cause fetal exhaustion or death to result in lower estriol production. But a recent observation
  146. that a surge of estriol production precedes the onset of labor, and that its premature occurrence can
  147. identify women at risk of premature delivery (McGregor, et al., 1995) suggests that the estriol surge
  148. might reflect the mother's increased production of adrenal androgens during stress. (This would be
  149. analogous to the situation in the polycystic ovary syndrome, in which excessive estradiol drives the
  150. adrenals to produce androgens.)
  151. </p>
  152. <p>
  153. Estetrol, which has one more hydroxyl group than estriol, is a "more sensitive and reliable indicator of
  154. fetal morbidity than estriol during toxemic pregnancies," because it starts to decrease earlier, or
  155. decreases more, than estriol. (Kundu, et al., 1978.) This seems to make it even clearer that the decline
  156. of estriol is a consequence, not a cause, of fetal sickness or death.
  157. </p>
  158. <p>
  159. A 1994 publication (B. Zumoff, "Hormonal profiles in women with breast cancer," <em>Obstet. Gynecol.
  160. Clin. North. Am. (U.S.) 21(4),</em> 751-772) reported that there are four hormonal features in women
  161. with breast cancer<strong>:</strong> diminished androgen production, luteal inadequacy, increased
  162. 16-hydroxylation of estradiol, and increased prolactin. The 16-hydroxylation converts estradiol into
  163. estriol.
  164. </p>
  165. <p>
  166. A new technique for radiographically locating a hormone-dependent breast cancer is based on the fact
  167. that estriol-sulfate is a major metabolite of estradiol. The technique showed the tumor to have about a
  168. six times higher concentration of estriol-sulfate than liver or muscle. (N. Shimura, et al., "Specific
  169. imaging of hormone-dependent mammary carcinoma in nude mice with [131I]-anti-estriol 3-sulfate
  170. antibody," <em>Nucl. Med. Biol. (England) 22(5),</em> 547-553, 1995.)
  171. </p>
  172. <p>
  173. Another association of elevated conversion of estradiol to estriol with disease was found to occur in
  174. men who had a myocardial infarction, compared to controls who hadn't. (W. S. Bauld, et al., 1957.)
  175. </p>
  176. <p>
  177. The estrogens in clover have been known for several decades to have a contraceptive action in sheep, and
  178. other phytoestrogens are known to cause deformities in the genitals, feminization of men, and anatomical
  179. changes in the brain as well as functional masculinization of the female brain. (Register, et al., 1995;
  180. Levy, et al, 1995; Clarkson, et al., 1995; Gavaler, et al., 1995.) The effects of the phytoestrogens are
  181. very complex, because they modify the sensitivity of cells to natural estrogens, and also modify the
  182. metabolism of estrogens, with the result that the effects on a given tissue can be either pro-estrogenic
  183. and anti-estrogenic. For example, the flavonoids, naringenin, quercetin and kaempherol (kaempherol is an
  184. antioxidant, a phytoestrogen, and a mutagen) modify the metabolism of estradiol, causing increased
  185. bioavailability of both estrone and estradiol. (W. Schubert, et al., "Inhibition of 17-beta-estradiol
  186. metabolism by grapefruit juice in ovariectomized women," <em>Maturitas (Ireland) 30(2-3),</em> 155-163,
  187. 1994.)
  188. </p>
  189. <p>
  190. Why do plants make phytoestrogens? There is some information indicating that these compounds evolved to
  191. regulate the plants' interactions with other organisms--to attract bacteria, or to repel insects, for
  192. example, rather than just as pigment-forming materials. (Baker, 1995.) The fact that some of them bind
  193. to our "estrogen receptors" is probably misleading, because of their many other effects, including
  194. inhibiting enzyme functions involved in the regulation of steroids and prostaglandins. Their
  195. biochemistry in animals is much more complicated than that of natural estrogens, which is itself so
  196. complicated that we can only guess what the consequences might be when we change the concentration and
  197. the ratio of substances in that complex system. (See quotation from Velardo, et al., page 6)
  198. </p>
  199. <p>
  200. These "natural" effects in sheep were forerunners of the observed estrogenic effects in wild animals,
  201. caused by pollutants. Twenty-five years ago I reviewed many of the issues of estrogen's toxicity, and
  202. the ubiquity of estrogenic substances, and since then have regularly spoken about it, but I haven't
  203. concentrated much attention on the phytoestrogens, because we can usually just choose foods that are
  204. relatively free of them. They are so often associated with other food toxins--antithyroid factors,
  205. inhibitors of digestive enzymes, immunosuppressants, etc.--that the avoidance of certain foods is
  206. desirable. Recently an advocate of soybeans said "if they inhibit the thyroid, why isn't there an
  207. epidemic of hypothyroidism in Asia?" I happened to hear this right after seeing newspaper articles about
  208. China's problem with 100,000,000 cretins<strong>;</strong> yes, Asia has endemic hypothyroidism, and
  209. beans are widely associated with hypothyroidism.
  210. </p>
  211. <p>
  212. When I first heard about clover-induced miscarriages in sheep, I began reading about the subject,
  213. because it was relevant to the work I was doing at that time on reproductive aging. Sheep which are
  214. adapted to living at high altitude, where all animals have reduced fertility, have an adaptive type of
  215. hemoglobin, with a greater affinity for oxygen. Fetal hemoglobin, in animals at sea-level, has a great
  216. affinity for oxygen, making it possible for the fetus to get enough oxygen, despite its insulation from
  217. the mother's direct blood supply. The high-altitude-tolerant sheep have hemoglobin which is able to
  218. deliver sufficient oxygen to the uterus to meet the needs of the embryo/fetus, even during relative
  219. oxygen-deprivation. These sheep are able to sustain pregnancy while grazing on clover. It seemed evident
  220. that estrogen and high altitude had something in common, namely, oxygen deprivation, and it also seemed
  221. evident that these sheep provided the explanation for estrogen's abortifacient effects.
  222. </p>
  223. <p>
  224. Estrogen's effects, ranging from shock to cancer, all seem to relate to an interference with the use of
  225. oxygen. Different estrogens have different affinities for various tissues, and a given substance is
  226. likely to have effects other than estrogenicity, and the presence of other substances will modify the
  227. way a tissue responds, but the stressful shift away from oxidative production of energy is the factor
  228. that all estrogens have in common. Otherwise, how could suffocation and x-irradiation have estrogenic
  229. effects?
  230. </p>
  231. <p>
  232. Pharmaceutical misrepresentations regarding the estrogens rank, in terms of human consequences, with the
  233. radiation damage from fall-out from bomb tests and reactor-leaks, with industrial pollution, with
  234. degradation of the food supply--with genocide, in fact.
  235. </p>
  236. <p>
  237. Advertising gets a bad name when it can't be distinguished from mass murder. At a certain point, we
  238. can't afford to waste our time making subtle distinctions between ignorance and malevolence. If we begin
  239. pointing out the lethal consequences of "stupid" or quasi-stupid commer- cial/governmental policies, the
  240. offenders will have the burden of proving that their actions are the result of irresponsible ignorance,
  241. rather than criminal duplicity. From the tobacco senators to the chemical/pharmaceutical/food/energy
  242. industries and their agents in the governmental agencies, those who do great harm must be held
  243. responsible.
  244. </p>
  245. <p>
  246. The idea of corporate welfare, in which public funds are given in massive subsidies to rich
  247. corporations, is now generally recognized. Next, we have to increase our consciousness of corporate
  248. responsibility, and that ordinary criminal law, especially RICO, can be directly applied to
  249. corporations. It remains to be seen whether a government can be made to stop giving public funds to
  250. corporations, and instead, to begin enforcing the law against them--and against those in the agencies
  251. who participated in their crimes.
  252. </p>
  253. <p>
  254. In the U.S., the death penalty is sometimes reserved for "aggravated homicide." If those who kill
  255. hundreds of thousands for the sake of billions of dollars in profits are not committing aggravated
  256. homicide, then it must be that no law written in the English language can be objectively interpreted,
  257. and the legal system is an Alice in Wonderland convenience for the corporate state.

  303. present in the mammalian circulation during various phases of the sex cycle and are known to modify

  309. R. C. Merrill, "Estriol: A review," <em>Physiol. Revs. 38(3),</em> 463-480, 1958. <strong>"...estriol
  310. itself is a potent estrogen, contrary to the usual conception of its being just a metabolite of the
  311. more potent estrone and estradiol.</strong> Although ordinarily less effective than estrone and
  312. estradiol in promoting vaginal cornification, estriol, under optimum conditions, approaches their
  313. effectiveness for this purpose. Estriol is more potent than estrone or estradiol in causing
  314. establishment and opening of the vaginal orifice, in promoting imbibition of uterine fluid, in
  315. increasing lactic dehydrogenase activity in the uterus, and in stimulating mitotic activity in the
  316. epidermis of the mouse ear. The activity of estriol is of the same order of magnitude as that of estrone
  317. and estradiol in other estrogenic actions, such as to promote uterine growth at low concentrations
  318. (although less effective at high doses), to increase beta-glucuronidase and reduced diphosphopyridine
  319. nucleotide oxidase activity in the uterus, to reduce motility of the uterus in vivo, and to stimulate
  320. ovarian growth, body weight, phagocytosis of carbon by reticuloendothelial cells, ciliary movements of
  321. the buccopharyngeal mucose of the frog, and new bone formation. The fibromatogenic activity of estriol
  322. in the guinea pig is much less than that of estrone or estradiol. Recent experiments suggest and partly
  323. verify the hypothesis that estriol stimulates the cervix, vagina and vulva more effectively than estrone
  324. or estradiol, whereas the latter are much more effective on the corpus uteri."

  337. substances that were previously considered to be 'weak' or inert may well play a role in the
  338. reproductive process." <strong>"We have been impressed with the probability that any endocrine
  339. receptor-organ response is not accomplished by the independent action of one hormone alone. It
  340. appears more likely that such response is the physiological expression of the sum total of the
  341. biologic hormones and their metabolites in concert on the receptor organs."</strong> "The effect of
  342. estriol on the birth rate of these rats was more dramatic." "...when estriol was used before mating, it
  343. reduced the litter size to 66 per cent of the controls." "However, when the same dose was employed from
  344. the day of mating and daily thereafter beyond the time of usual implantation, 6 days later, a reduction
  345. of live births to 33 per cent of the controls was produced. In this experiment the medication was
  346. withheld until after ovulation had presumably occurred. The presence of placental scars and an increased
  347. incidence of abortions and stillbirths argues against the possibility that the fertile ova have been
  348. 'locked' by the estrogen in the tubes." "...the incidence of placental scars, abortions, and stillbirths
  349. further bears witness to the possibility that the steroids employed interfered with the optimum
  350. differentiation of progestational endometrial changes, rather than affecting any suppression of
  351. ovulatory mechanisms."
