Dr. Vliet offers a different perspective on hormones
This landmark work in women’s health identifies and offers solutions to the hormonal dysfunctions afflicting millions of young women, teens, and even children, that rob women of future fertility and contribute to devastating problems — from early onset puberty and obesity to depression and increased cancer risk. Women’s health is more than breast cancer, pregnancy, and menopause. In this groundbreaking new work, Dr. Elizabeth Lee Vliet identifies and explains rarely acknowledged, pervasive threats to young women’s health and fertility — PCOS (Polycystic Ovary Syndrome), POD (Premature Ovarian Decline), and Premature Ovarian Failure (menopause in the young) — and the overlooked causes of endometriosis, cystitis, early puberty, allergies, heart disease, mood disorders, depression, chronic fatigue, fibromyalgia, bone loss, anxiety, obesity, and diabetes.
A kind of “Silent Spring” of women’s health, “It’s My Ovaries, Stupid!” presents compelling evidence from worldwide research that common environmental toxins and endocrine disruptors in pesticides, plastic food wrappers, food additives, preservatives, soy supplements, aspartame in diet sodas and junk food, and more — as well as lifestyle factors such as stress — can all profoundly disrupt hormone function, even in childhood.Insidious robbers of quality of life, fertility, and health, hormone dysfunctions are on the rise today, afflicting younger and younger women.Why? What can you do about it? How can you get tested? What treatments are available? Dr. Vliet interprets the latest scientific research and draws on more than twenty years of clinical experience to answer these and many other crucial questions about commonhealth problems in young women.Whose job is it to take care of the ovaries…beyond their function in reproduction? Why do you have trouble getting help for “hormone problems” that are clearly linked to your monthly cycle?
“It’s My Ovaries, Stupid!” bridges this gap in women’s health care and shows you how to understand your symptoms and get reliable tests, how to receive treatment and improve your health, how to wade through the controversies surrounding hormone replacement therapy, and how to explore cutting-edge options for thyroid problems.You can’t afford “not” to read this book. Your life, your fertility, and your long-term health may depend on it. It’s not all in your head, and it’s not just stress. It’s your ovaries!
Partisan Perspectives in the Medical Literature, Journal of General Internal Medicine, 2010
Unfavorable results of major studies have led to a large shrinkage of the market for hormone replacement therapy (HRT) in the last 6 years. Some scientists continue to strongly support the use of HRT.
We analyzed a sample of partisan editorializing articles on HRT to examine their arguments, the reporting of competing interests, the journal venues and their sponsoring societies.
Through Thomson ISI database, we selected articles without primary data written by the five most prolific editorialists that addressed clinical topics pertaining to HRT and that were published in regular journal issues in 2002–2008.
We recorded the number of articles with a partisan stance and their arguments, the number of partisan articles that reported conflicting interests, and the journal venues and their sponsoring societies publishing the partisan editorials.
We analyzed 114 eligible articles (58 editorials, 16 guidelines, 37 reviews, 3 letters), of which 110 (96%) had a partisan stance favoring HRT. Typical arguments were benefits for menopausal and related symptoms (64.9%), criticism of unfavorable studies (78.9%), preclinical data that showed favorable effects of HRT (50%), and benefits for major outcomes such as osteoporosis and fractures (49.1%), cardiovascular disease (31.6%), dementia (24.6%) or colorectal cancer (20.2%), but also even breast cancer (4.4%). All 5 prolific editorialists had financial relationships with hormone manufacturers, but these were reported in only 6 of the 110 partisan articles. Four journals published 15–37 partisan articles each. The medical societies of these journals reported on their websites that several pharmaceutical companies sponsored them or their conferences.
There is a considerable body of editorializing articles favoring HRT use and very few of these articles report conflicts of interest. Full disclosure of conflicts of interest is needed, especially for articles without primary data.

Menopause may be a risk factor for hearing loss, and postmenopausal hormone therapy (HT) has been proposed to slow hearing decline; however, there are no large prospective studies. We prospectively examined the independent relations between menopause and postmenopausal HT and risk of self-reported hearing loss.
Prospective cohort study among 80,972 women in the Nurses’ Health Study II, baseline age 27 to 44 years, followed from 1991 to 2013. Baseline and updated information was obtained from detailed validated biennial questionnaires. Cox proportional-hazards regression models were used to examine independent associations between menopausal status and postmenopausal HT and risk of hearing loss.
After 1,410,928 person-years of follow-up, 18,558 cases of hearing loss were reported. There was no significant overall association between menopausal status, natural or surgical, and risk of hearing loss. Older age at natural menopause was associated with higher risk. The multivariable-adjusted relative risk of hearing loss among women who underwent natural menopause at age 50+ years compared with those aged less than 50 years was 1.10 (95% confidence interval [CI] 1.03, 1.17). Among postmenopausal women, oral HT (estrogen therapy or estrogen plus progestogen therapy) was associated with higher risk of hearing loss, and longer duration of use was associated with higher risk (P trend < 0.001). Compared with women who never used HT, the multivariable-adjusted relative risk of hearing loss among women who used oral HT for 5 to 9.9 years was 1.15 (95% CI 1.06, 1.24) and for 10+ years was 1.21 (95% CI 1.07, 1.37).
Older age at menopause and longer duration of postmenopausal HT are associated with higher risk of hearing loss.

The development of the mammary gland is a hormone-regulated event.
Several factors can dysregulate its growth and make the gland more susceptible to cellular transformation.
Among these factors, perinatal exposure to xenoestrogens and hormone replacement therapy has been associated with increased risk of developing breast cancer.
Perinatal Exposure to Bisphenol A or Diethylstilbestrol Increases the Susceptibility to Develop Mammary Gland Lesions After Estrogen Replacement Therapy in Middle-Aged Rats, US National Library of Medicine National Institutes of Health, Hormones and Cancer, April 2017, Volume 8, Issue 2, pp 78–89, NCBI PubMed PMID: 28078498, 2017 Apr 8.
Here, we assessed the effects induced by estrogen replacement therapy (ERT) in ovariectomized (OVX) middle-aged rats and whether perinatal exposure to diethylstilbestrol (DES) or bisphenol A (BPA) modified these effects in the mammary gland.
Pregnant rats were orally exposed to vehicle, 5 μg DES/kg/day, or 0.5 or 50 μg BPA/kg/day from gestational day 9 until weaning. Then, 12-month-old offspring were OVX and treated with 17β-estradiol for 3 months.
Morphological changes and the percentage of epithelial cells that proliferated or expressed estrogen receptor alpha (ESR1) and progesterone receptor (PR) were analyzed in mammary gland samples of 15-month-old animals.
ERT induced lobuloalveolar hyperplasia and ductal cysts in the mammary gland of middle-aged rats, associated with a higher proliferation index of epithelial cells.
Perinatal exposure to DES followed by ERT increased the number of cysts and induced the formation of fibroadenoma and ductal carcinoma in situ, without modifying the expression of ESR1 or PR.
Also, after 3 months of ERT, BPA-exposed rats had a higher incidence of ductal hyperplasia and atypical lobular hyperplasia than animals under ERT alone.
In conclusion, perinatal exposure to xenoestrogens increases the susceptibility of the mammary gland to develop cysts and hyperplastic lesions when confronted with ERT later in life.

British study finds combined HRT nearly triples risk of breast cancer
2% of women monitored for six years got breast cancer – and they were 2.7 times more likely to contract it if they were on combined HRT than if they were not.
Aaccording to the study’s findings, combined HRT increases the risk of breast cancer by 170%.
Menopausal hormone therapy (MHT) increases breast cancer risk; however, most cohort studies omit MHT use after enrolment and many infer menopausal age.
We used information from serial questionnaires from the UK Generations Study cohort to estimate hazard ratios (HRs) for breast cancer among post-menopausal women with known menopausal age, and examined biases induced when not updating data on MHT use and including women with inferred menopausal age.
Menopausal hormone therapy and breast cancer: what is the true size of the increased risk?, nature, 28 July 2016.
Among women recruited in 2003–2009, at 6 years of follow-up, 58 148 had reached menopause and 96% had completed a follow-up questionnaire. Among 39 183 women with known menopausal age, 775 developed breast cancer, and the HR in relation to current oestrogen plus progestogen MHT use (based on 52 current oestrogen plus progestogen MHT users in breast cancer cases) relative to those with no previous MHT use was 2.74 (95% confidence interval (CI): 2.05–3.65) for a median duration of 5.4 years of current use, reaching 3.27 (95% CI: 1.53–6.99) at 15+ years of use. The excess HR was underestimated by 53% if oestrogen plus progestogen MHT use was not updated after recruitment, 13% if women with uncertain menopausal age were included, and 59% if both applied. The HR for oestrogen-only MHT was not increased (HR=1.00; 95% CI: 0.66–1.54).

Lack of updating MHT status through follow-up and inclusion of women with inferred menopausal age is likely to result in substantial underestimation of the excess relative risks for oestrogen plus progestogen MHT use in studies with long follow-up, limited updating of exposures, and changing or short durations of use.
There are things women can do to reduce breast cancer risk
Researchers estimate that close to 30% of all breast cancers in the U.S. could be prevented if women maintained a healthy weight, do not use hormone therapy for menopause, and cut back on drinking and smoking. That conclusion held true even for women who were at a high risk for breast cancer due to family history and genetics.
Breast Cancer Risk From Modifiable and Nonmodifiable Risk Factors Among White Women in the United States, JAMA Oncology, May 26, 2016.
An improved model for risk stratification can be useful for guiding public health strategies of breast cancer prevention.
To evaluate combined risk stratification utility of common low penetrant single nucleotide polymorphisms (SNPs) and epidemiologic risk factors.
Design, Setting, and Participants
Using a total of 17 171 cases and 19 862 controls sampled from the Breast and Prostate Cancer Cohort Consortium (BPC3) and 5879 women participating in the 2010 National Health Interview Survey, a model for predicting absolute risk of breast cancer was developed combining information on individual level data on epidemiologic risk factors and 24 genotyped SNPs from prospective cohort studies, published estimate of odds ratios for 68 additional SNPs, population incidence rate from the National Cancer Institute-Surveillance, Epidemiology, and End Results Program cancer registry and data on risk factor distribution from nationally representative health survey. The model is used to project the distribution of absolute risk for the population of white women in the United States after adjustment for competing cause of mortality.
Single nucleotide polymorphisms, family history, anthropometric factors, menstrual and/or reproductive factors, and lifestyle factors.
Main Outcomes and Measures
Degree of stratification of absolute risk owing to
The average absolute risk for a 30-year-old white woman in the United States developing invasive breast cancer by age 80 years is 11.3%. A model that includes all risk factors provided a range of average absolute risk from 4.4% to 23.5% for women in the bottom and top deciles of the risk distribution, respectively. For women who were at the lowest and highest deciles of nonmodifiable risks, the 5th and 95th percentile range of the risk distribution associated with 4 modifiable factors was 2.9% to 5.0% and 15.5% to 25.0%, respectively. For women in the highest decile of risk owing to nonmodifiable factors, those who had low BMI, did not drink or smoke, and did not use MHT had risks comparable to an average woman in the general population.
Here Are The Things Women Can Do to Avoid Breast Cancer, time, May 26, 2016.
Conclusions and Relevance
This model for absolute risk of breast cancer including SNPs can provide stratification for the population of white women in the United States. The model can also identify subsets of the population at an elevated risk that would benefit most from risk-reduction strategies based on altering modifiable factors. The effectiveness of this model for individual risk communication needs further investigation.
Experts Recommend Assessing Individual Benefits, Risks of Menopausal Therapies
Endocrine Society – Hormone Science to Health – press release Experts Recommend Assessing Individual Benefits, Risks of Menopausal Therapies
Washington, DC – The Clinical Practice Guideline (CPG), entitled “Treatment of Symptoms of the Menopause: An Endocrine Society Clinical Practice Guideline” was published online and will appear in the November 2015 print issue of the Journal of Clinical Endocrinology and Metabolism (JCEM), a publication of the Endocrine Society.
Menopause is the life stage that takes place when a woman’s ovaries dramatically decrease production of the hormones estrogen and progesterone, and her menstrual periods stop. The average age of an American woman experiencing menopause is around 51 years old.
During menopause, many women experience symptoms such as hot flashes, night sweats, sleep disturbances, mood changes, joint pain, recurrent urinary tract infections, and difficult or painful sexual intercourse. These symptoms can start in the years before a woman’s final menstrual period and last for more than a decade.
Women now have a broader range of treatment options for menopausal symptoms than ever before, but many clinicians are reluctant to pursue them. A 2012 Endocrine Society survey found that 72 percent of women currently experiencing menopause symptoms had not received any treatment for them.
Hormone therapy—at one time the most popular treatment for menopausal symptoms— has been under intense scrutiny since 2002, when a large government study called the Women’s Health Initiative (WHI) reported that hormone therapy – specifically the combination of conjugated equine estrogens and medroxyprogesterone acetate (Prempro) – increased the risk for blood clots, stroke, breast cancer and heart attacks in postmenopausal women aged 50 to 79 years at study onset. But additional research conducted in the ensuing years indicated the level of risk depends on the individual woman’s health history, age and other factors. Experts have formed a consensus that the benefits of menopausal hormone therapy exceed the risks for most healthy women seeking relief of menopausal symptoms.
“There is no need for a woman to suffer from years of debilitating menopausal symptoms, as a number of therapies, both hormonal and non-hormonal are now available,” said Cynthia A. Stuenkel, MD, the chair of the task force that authored the guideline and an endocrinologist specializing in menopause at the University of California, San Diego. “Every woman should be full partners with her health care providers in choosing whether treatment is right for her and what treatment option best suits her needs. The decision should be based on available evidence regarding the treatment’s safety and effectiveness, as well as her individual risk profile and personal preferences.”
In the CPG – see full PDF – the Endocrine Society recommends that women with a uterus who decide to undergo menopausal hormone therapy with estrogen and progestogen be informed about risks and benefits, including the possible increased risk of breast cancer during and after discontinuing treatment. Health care providers should advise all women, including those taking menopausal hormone therapy, to follow guidelines for breast cancer screening.
Other recommendations from the CPG include:
The Hormone Health Network, the Endocrine Society’s public education arm, developed an interactive digital resource called the Menopause MapTM for women to explore the stages of menopause and learn about symptoms they may experience. The Menopause MapTM related resources are available. The Hormone Health Network also offers a digital toolkit for health care providers.
Other members of the Endocrine Society task force that developed this CPG include: Susan R. Davis of Monash University in Melbourne, Australia; Anne Gompel of the Université Paris Descartes in Paris, France; Mary Ann Lumsden of the University of Glasgow School of Medicine in Glasgow, Scotland; M. Hassan Murad of the Mayo Clinical in Rochester, MN; JoAnn V. Pinkerton of the University of Virginia in Charlottesville, VA; and Richard J. Santen of the University of Virginia Health System in Charlottesville, VA.This CPG was co-sponsored by the Australasian Menopause Society, British Menopause Society, European Society of Endocrinology and the International Menopause Society.
The Society established the CPG Program to provide endocrinologists and other clinicians with evidence-based recommendations in the diagnosis and treatment of endocrine-related conditions. Each CPG is created by a task force of topic-related experts in the field. Task forces rely on scientific reviews of the literature in the development of CPG recommendations as well as feedback from co-sponsoring societies, members of the Endocrine Society and expert reviewers. The Endocrine Society does not solicit or accept corporate support for its CPGs. All CPGs are supported entirely by Society funds. A list of CPGs can be found here.
