Hot Flashes and Sleep

Researchers writing in the medical journal Menopause say that ambient temperature and REM sleep patterns effect sleep in postmenopausal women.

Freedman RR, Roehrs TA.Effects of REM sleep and ambient temperature on hot flash-induced sleep disturbance. Menopause. 2006 Jul-Aug;13(4):576-83.

From the study abstract:
OBJECTIVE:: To determine whether hot flashes produce sleep disturbance in postmenopausal women.

DESIGN:: This study was performed in a university medical center laboratory with 18 postmenopausal women with hot flashes, six with no hot flashes, and 12 cycling women, all healthy and medication free. Polysomnography, skin and rectal temperatures, and skin conductance to detect hot flashes were recorded for four nights.

Nights 2, 3, and 4 were run at 30 degrees C (86 degrees F), 23 degrees C (about 73.5 degrees F), and 18 degrees C (about 64.5 degrees F) in randomized order.

RESULTS:: During the first half of the night, the women with hot flashes had significantly more arousals and awakenings than the other two groups and the 18 degrees C ambient temperature (about 64.5 degrees F) significantly reduced the number of hot flashes.

These effects did not occur in the second half of the night. In the first half of the night, most hot flashes preceded arousals and awakenings. In the second half, this pattern was reversed.

CONCLUSIONS: In the second half of the night, rapid eye movement sleep suppresses hot flashes and associated arousals and awakenings. This may explain previous discrepancies between self-reported and laboratory-reported data in postmenopausal women with hot flashes.

Hot Flashes and Insomnia

Researchers writing in the Archives of Internal Medicine say: “Severe hot flashes are strongly associated with chronic insomnia in midlife women. The presence of hot flashes should be systematically investigated in women with insomnia. Treating hot flashes could improve sleep quality and minimize the deleterious consequences of chronic insomnia.”

Ohayon MM. Severe hot flashes are associated with chronic insomnia. Arch Intern Med. 2006 Jun 26;166(12):1262-8

BACKGROUND: Because hot flashes can occur during the night, their presence has been frequently associated with insomnia in women with symptoms of menopause. However, many factors other than hot flashes or menopause can be responsible for insomnia, and several factors associated with insomnia in the general population are also commonly observed in perimenopausal and postmenopausal women who have hot flashes.

METHODS: A random sample of 3243 subjects (aged >/=18 years) representative of the California population was interviewed by telephone. Included were 982 women aged 35 to 65 years. Women were divided into 3 groups according to menopausal status: premenopause (57.2%), perimenopause (22.3%), and postmenopause (20.5%). Hot flashes were counted if they were present for at least 3 days per week during the last month and were classified as mild, moderate, or severe according to their effect on daily functioning.

Chronic insomnia was defined as global sleep dissatisfaction, difficulty initiating sleep, difficulty maintaining sleep, or nonrestorative sleep, for at least 6 months. Diagnoses of insomnia were assessed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, classification.

RESULTS: Prevalence of hot flashes was 12.5% in premenopause, 79.0% in perimenopause, and 39.3% in postmenopause. Prevalence of chronic insomnia was reported as 36.5% in premenopause, 56.6% in perimenopause, and 50.7% in postmenopause.

Prevalence of symptoms of chronic insomnia increased with the severity of hot flashes, reaching more than 80% in perimenopausal women and postmenopausal women who had severe hot flashes. In multivariate analyses, severe hot flashes were significantly associated with symptoms and a diagnosis of chronic insomnia. Poor health, chronic pain, and sleep apnea were other significant factors associated with chronic insomnia.

CONCLUSIONS: Severe hot flashes are strongly associated with chronic insomnia in midlife women. The presence of hot flashes should be systematically investigated in women with insomnia. Treating hot flashes could improve sleep quality and minimize the deleterious consequences of chronic insomnia.

Maintaining Muscle Strength May Counteract Postmenopausal Bone Loss

Sirola J, Rikkonen T, Tuppurainen M, Honkanen R, Jurvelin JS, Kroger H. Maintenance of muscle strength may counteract weight-loss-related postmenopausal bone loss-a population-based approach. Osteoporos Int. 2006 Feb 21.

Researchers writing in the medical journal Osteoporosis International say that maintaining muscle strength may counteract postmenopausal bone loss related to weight loss and that exercise that improves muscle strength may be encouraged for postmenopausal women with weight loss intentions for other health reasons.

From the study abstract:
INTRODUCTION: “Weight loss significantly increases postmenopausal bone loss, but the effects of muscle strength change on weight-loss-associated bone loss remain unclear. The study population, 587 peri- and postmenopausal women, was a random sample of the original Osteoporosis Risk Factor and Prevention Study (OSTPRE) study cohort in Kuopio, Finland.

Bone mineral density (BMD) at the lumbar spine (LS) and femoral neck (FN) was measured with dual x-ray absorptiometry, and grip strength was measured with a pneumatic squeeze dynamometer at baseline in 1989-1991 and at the 10-year follow-up in 1999-2001.

METHODS: Women were divided into three groups according to change in age-grouped grip-strength quartile in both of the measurements: “decreased”, “maintained” , and “improved”.

In addition, the study sample was divided into two groups according to weight change during the follow-up: weight losers and weight gainers.

RESULTS: There were no differences in the change status of grip (muscle) strength between the weight loss and weight gain groups.

Women losing weight during the follow-up and within the improved grip-strength-change group had a significantly lower bone loss rate compared with those in the maintained and decreased grip-strength-change groups.

This was in contrast to women who gained weight during the follow-up (not significant between any grip-strength-change groups). Furthermore, women who lost body weight and were in the improved grip-strength-change group had a bone loss rate comparable with that of the women who gained body weight (not significant).

CONCLUSION: The present study suggests that maintaining muscle strength may counteract postmenopausal bone loss related to weight loss. Accordingly, exercise that improves muscle strength may be encouraged for postmenopausal women with weight loss intentions for other health reasons.”

Question from Radio Show Caller
Caller: I entered menopause or peri-menopause just a few years ago, I found some things that worked for me, and now they are no longer working even though I am on bio-identical hormones. I started having the nights sweats, the fatigue, moodiness and things like that. I have tried several estrogens and several different things. So far, no luck, meaning I am experiencing those symptoms still, and I have occasional periods. What do I do?

Dr. Darrow: You need to get your hormone levels checked. If you have occasional periods then you are still peri-menopausal, which is the most difficult phase, because at that stage your ovaries are erratically putting out different amounts of hormones, it is very tough at that stage to really get someone on track.

Progesterone is probably the most important thing that you can have in your system because it is a relaxant, it modulates the amount of estrogen so you don’t get it too high, like those months that you are flaring with estrogen and probably moody and feeling a little bit out of whack and retaining fluids, etc.

The way I like people to take Progesterone is by pill just before they go to sleep, I give it to men and women. For women, it is the most relaxing of all the hormones, it also helps build bone. I don’t know if you had a bone densitometry taken recently but it is something that is very important, if you need one you can always call our clinic because that tells the tale right there if you have enough estrogen, testosterone and progesterone because those hormones build up the bone structure, it is most important to maintain the bones, because if the bones are demineralizing, there is a risk of fracture.

You need to have your hormone levels checked. You also need to have very adequate levels of testosterone, not the levels that a man has, but the upper levels that a strong young women has and if you are peri-menopausal, I am not sure how old you are.

Caller: I am 54

Dr. Darrow: Then your Testosterone level has probably dropped down to nothing, it does for most women, and that, in it of itself, once supplemented, can bring you back into alignment. It is also good for the libido and quality of life and the ability to accomplish things.

Estrogen Selected Research

Estrogen and Women’s Heart Disease
Grodstein F, Stampfer MJ. Estrogen for women at varying risk of coronary disease. Maturitas 1998;30:19-26.

Study: Researchers cited that estrogen was beneficial for heart disease risk. “However, few studies have assessed the impact of estrogen use among women with a distinctly higher cardiovascular risk.”

The researchers stated: “Analysis of the effect of estrogen within different risk factor categories in the 16-year follow up of the Nurses’ Health Study confirms that although relevant risk estimates are highly similar, the magnitude of the protective effect of estrogen is more pronounced among women with high baseline risk of disease.”

Estrogen, Depression, and Blood Pressure

Canada SA, Hofkamp M, Gall EP, et al. Estrogen replacement therapy, subsyndromal depression, and orthostatic blood pressure regulation. Behav Med. 2003;29:101-106.

Study: From the abstract: “Although estrogen replacement therapy (ERT) alleviates depressed moods in postmenopausal women, it is not known whether ERT is equally effective in reducing affective and somatic depressive complaints. One of the authors’ goals in this study was to examine possible differences between women receiving and not receiving ERT.”

The researchers stated: “The authors studied a group of postmenopausal women. Somatic symptoms in the ERT group were significantly lower than in the Non-ERT group. Affective scores were only marginally lower in the ERT group…In response to orthostatic challenge, the change in systolic blood pressure was significantly smaller in the ERT group. Apparently ERT is associated with more effective blood pressure regulation.”

Breast Cancer and Estrogen Replacement Therapy
Researchers writing in the August 6, 2005 edition of the British Medical Journal say maybe the risk of developing breast cancer from estrogen replacement therapy is not as great as everyone thought.

The researchers noted that estrogen therapy accounted for eight additional cases out of 10,000 women.

In 2002, headlines cited that researchers discovered that estrogen therapy could double the risk for getting breast cancer.Read abstract

Estrogen and Physical Appearance
Women With Higher Levels of Estrogen Have Prettier Faces
Researchers at the University of St. Andrews in Scotland announced that women who had higher amounts of estrogen in their urine were found to be more attractive than women who had lesser amounts.

What Effects Does Estrogen Have On The Skin?
Researchers have found that “Estrogen loss at menopause has a profound influence on skin.” Writing in the medical journal Climacteric, study authors noted, “Estrogen treatment in postmenopausal women has been repeatedly shown to increase collagen content, dermal thickness and elasticity, and data on the effect of estrogen on skin water content are also promising.”

Hormone Replacement Therapy and Possible Cardiovascular Benefits in Women
Researchers writing in the medical journal Climacteric say that “Women who receive 2-3 years of HRT after menopause do not have increased all-cause mortality, and results of the present study suggest relative cardiovascular benefits compared to those who had not used hormones.” Read more

Estrogen and Sun Damaged Skin
Researchers at the University of Michigan Department of Dermatology are currently recruiting subjects to participate in a study to test Estrogen’s effect on the skin.

Risk of stroke and hormone replacement therapy
Researchers writing in the medical journal Maturitas say that there is no significant association between hormone therapy and risk of total stroke in women during 10.5 years follow-up.

Postmenopause and periodontal disease
A recent study in the Journal of Periodontology says that in an 11.7 year follow up, 57.5 percent of women lost at least one tooth after menopause.

Synthetic Hormone Replacement—Fact and Fiction

One of the things our media is very good at is blowing a story way out of proportion at the expense of presenting all the facts. So it was with the world-wide reporting of the dangers of Hormone Replacement Therapy in the aftermath of the JAMA article. News reports circled the globe in nearly every news outlet, that a protocol taken by millions and millions of women in the United States, estrogen and progestin, when taken in combination, greatly increased the chances of serious health problems and even death.

As part of the Woman’s Health Initiative (WHI), a very large scale study which sought to examine potential health strategies to “reduce the incidence of heart disease, breast and colorectal cancer, and fractures in postmenopausal women,” researchers studied the effects of Hormone Replacement Therapy, (Estrogen and Progestin). Originally designed as an eight year study, the study was halted three years early when the researchers accumulating their findings and discovered that HRT was responsible for increases in incidences of breast cancer, heart attack, stroke, and blood clots in the lungs (pulmonary embolism) and legs (deep venous thrombosis).

What the media failed to mention was that taking estrogen in a synthesized version, distilled from pregnant horse urine plus a synthetic progestin, when taken in combination, greatly increased the chances of developing breast cancer, heart disease, strokes and blood clots. So instead of saying the drug Prempro (an estrogen-plus-progestin therapy) was found to cause a greater incidence and certain cancers, it was Estrogen and Progestin! (In the section about Progesterone, read about the differences between Progestin and the naturally occurring Progesterone).

Bio-identical Hormones

Years before the risks of synthetic hormone replacement therapy was made known, medical pioneers such as New York Times best-selling author John Lee, M.D., spoke out about these very same dangers, in his book What your Doctor May Not Be Telling You About Menopause. Dr. Lee says quite plainly “(there are…) reams of evidence that synthetic estrogens are highly toxic and carcinogenic.”

Dr. Lee and others took a skeptical view of the pharmaceutical industry that pushed synthetic hormones, because they are produced by companies who hold exclusive patents on these drugs and as such make billions of dollars. Bio-identical hormones are not patentable and are therefore incapable of being a huge profit maker.

What are Bio-identical hormones?
As mentioned earlier, bio-identical hormones are not “Natural Hormones,” even though they are derived from plants such as the Wild Yam and soy plants. During the process to convert plant derivatives to bio-identical hormones, a chemical or synthesizing process must be performed to the highest standards by a reputable laboratory.

The synthesized product becomes a bio-identical hormone, a product whose molecular structure exactly matches that of human hormones and is processed by the human body as a “naturally” occurring hormone.

The difference between synthetic estrogen and the body’s own hormones stresses the difference between synthetic and bio-identical hormones. Synthetic estrogen derived from horses contains 30 or 40 different estrogens types that a horse needs, but a human female does not. The human female only produces estrone (E1), Estradiol (E2), & Estriol (E3). Bio-identical hormones replicate the human estrogens.

But I thought no hormone replacement therapy was safe!
Opponents of bio-identical hormones point out that there are no long-term studies that show bio-identical hormones are any safer than the synthetic hormones.

Bio-identical hormones should be prescribed in the smallest dose possible to restore the body to its natural level of hormone. Regular blood or saliva or urine level monitoring and physical examination will help the physician administer the right dosage for each woman.

The Estrogen Controversy

From the article abstract: The Women’s Health Initiative (WHI) hormone trials have been widely interpreted as demonstrating that combined menopausal hormone therapy (HT) fails to protect against—and may increase—cardiovascular disease (CVD), stroke, and dementia in menopausal women, regardless of whether initiated early in the menopause or later. This conclusion does not agree with results of large epidemiological studies showing protection by HT and by estrogen replacement alone (ET) against CVD and dementia. One possible reason for this inconsistency is that the epidemiologic data are confounded by “healthy user bias.” Another possible explanation is that most women in the observational studies initiated ET or HT at or near the menopausal transition, at which point there is little or no arterial injury, whereas, in the WHI studies, older women, averaging approximately 12 years postmenopausal, many of whom would have had significant asymptomatic atherosclerosis, were treated. Substantial data demonstrate atheropreventive effects of estrogen before vascular damage occurs, whereas adverse effects of oral estrogen on thrombosis and inflammation may predominate once complex atheromas are present. Similarly, the excess of dementia observed in older WHI women treated with oral conjugated estrogen could be due to cerebral thromboses (multi infarct dementia). Given the uncertain relevance of the WHI (and other published randomized clinical trials) to initiation of HT in perimenopausal women, and its subsequent continuation for atheroprevention, new trials will be needed to resolve whether early intervention with estrogen may prevent CVD and/or dementia. The Kronos Early Estrogen Prevention Study (KEEPS), which began in mid 2005, is a randomized, controlled multicenter trial of HT in recently menopausal women. It will examine surrogate end points as well as risk factors for atherosclerosis.

Estrogen for Bone Density/Osteoporosis
Lafferty FW, Fiske ME. Postmenopausal estrogen replacement: A long-term cohort study. Am J Med 1994;1:66-77.

Study: A long-term study to determine the success of estrogen replacement in bone loss.

The researchers stated: “The mean cortical bone density at the distal third of the radius was significantly greater among the ERT subjects compared to the control subjects with the difference representing a 12.0% higher bone density with ERT.”

Estrogen for Cognition
Greene RA, Dixon W. The role of reproductive hormones in maintaining cognition. Obstet Gynecol Clin North Am. 2002;29:437-453.

Study: The researchers sought to show the relationship between hormones and cognition citing that “Estrogen has the most profound impact on brain functioning. ”

The researchers stated: “Although skeptics may believe that more definitive proof is necessary before recommending hormone replacement for their patients to preserve their cognitive health, it seems prudent to discuss the evidence available to empower the patient further to guide their own treatment options and validate their symptoms.

Postmenopause, periodontal disease and estrogen
A recent study in the Journal of Periodontology says that in an 11.7 year follow up, 57.5 percent of women lost at least one tooth after menopause. Bone loss is to blame!

The American Academy of Periodontology’s press release on ths study says “Estrogen deficiency after menopause and consequent loss of bone mineral density have been shown to be associated with increased rate of tooth loss. These relationships may be explained by increased severity of periodontal disease in estrogen deficiency.”

Estrogen

There is a great deal of fear and confusion when it comes to menopause and hormone supplementation. First, the term Hormone Replacement Therapy or HRT can conjure up the image of a cancer, stroke, and heart disease causing cocktail of synthetic hormones.

Next there is the “alternative,” Natural Hormone Replacement Therapy (NHRT). There is no Natural Hormone Replacement Therapy. Hormones for use in humans need to be synthesized from something. While many use the term, it is the sometimes favorite of internet sites selling “hormones,” and thus an easy target for critics who still favor the use of horse hormones and point to the “NHRT” websites as those making unsupported claims and being medically dangerous.

Sometimes, but incorrectly added to the latter group are the aptly and descriptively named “Bio-Identical Hormones.” Bio-identical Hormone Replacement Therapy (BHRT) is not “natural” hormones and should never be referred to as that. Their sources are natural, being derived from plant sources, but, they must be chemically altered to exactly match the hormones produced in the body.

This is where the “natural” confusion comes in. Bio-identical Hormones are engineered to exactly match the natural hormones present in the body, but they themselves are not “natural” but indeed, bio-identical.

I would like to point out here that NOT every woman coming in with peri-menospausal, menopausal or post-menopausal complaints is put on hormone therapy at our clinic and there are no studies that clearly show that bio-identical hormones are any safer than synthetic hormones.

Sometimes the desired results a women wants can be achieved by quitting smoking or drinking, altering a diet to avoid foods that could aggravate symptoms, such as coffee, sugars, and foods loaded with chemicals, getting more exercise, reducing stress, reducing exposure to caustic elements and more.

There are options to Hormone Replacement Therapy and these can and should be discussed with a physician knowledgeable in understanding all the options available to the peri-menospausal and menopausal woman. Just because Grandma went through menopause naturally, doesn’t mean she was the better for it!

Hormone replacement, peri-menopause and menopause
For over four decades doctors freely prescribed synthetic estrogen replacement to women in the throes of menopause to alleviate the myriad of symptoms associated with the “Change of Life.” It was an easy thing to do. A women would come in with “hot flashes,” “mood swings,” and “fatigue,” among other complaints and the doctor would simply give them estrogen. Why not? The women who took estrogen seemed to be more youthful, enjoy life more, and “had control of their bodies.”

The problem became supplying the demand for estrogen. To which “Estrogen Farms,” were set up to capture the urine of pregnant mares (where the name Premarin comes from (Pre=Pregnant, Mar=Mare, In=Urine) to glean the estrogen from it.

Synthetic horse-urine estrogen replacement was now the vogue and over 10,000,000 women were “in style.” Physicians felt comfortable putting women on this estrogen, since many studies proclaimed the vast benefits of estrogen replacement therapy. In fact, once on horse-estrogen, many women refused and still refuse to give it up!

Happy with horse estrogen

After menopause, estrogen levels in a woman’s body declines.

Estrogen Replacement Therapy (ERT) alleviated the familiar symptoms of menopause for many women.
With this decline often comes the familiar symptoms of:
1. Vaginal dryness, painful intercourse
2. Vaginal mucosal atrophy
3. Hot flashes
4. Night sweats
5. Fatigue
6. Mood swings and memory problems
7. Fluid retention
8. Sleep problems
9. Decreased libido
10. Involuntary loss of urine (stress incontinence)
11. More frequent urinary tract infections

It seemed like an idyllic world. Women wanted estrogen, the doctors were eager to comply, and the pharmaceutical industry was happy to produce.

Then on July 12, 2002, the world of synthetic estrogen replacement abruptly collapsed and panic filled women across the world. The Journal of the American Medical Association (JAMA) reported that Hormone Replacement Therapy was too dangerous to research!

Ask A Question?

Women, Testosterone and Cardiovascular Disease

Researchers writing in the medical journal Coronary Artery Disease say that their study “could suggest that the development of cardiovascular disease after menopause is due not only to estrogen decline but also to androgen decline.”

Montalcini T, Gorgone G, Gazzaruso C, Sesti G, Perticone F, Pujia A. Endogenous testosterone and endothelial function in postmenopausal women Coron Artery Dis. 2007 Feb;18(1):9-13.

OBJECTIVE: It is well known that coronary heart disease incidence increases in women after menopause. This phenomenon was related to reduced levels of female sex hormones. Estrogen decline, however, is not the only hormonal change during the postmenopausal period and estrogen administration did not protect women from cardiovascular disease. Therefore, it is justified to explore other hormonal changes. The role of androgens is still controversial. The aim of the present study was to investigate the relationship between endogenous sex hormones and endothelial function, measuring the brachial artery flow-mediated dilation.

METHODS AND RESULTS: Sixty postmenopausal women were consecutively enrolled and underwent a clinical and biochemical examination. Brachial artery flow-mediated dilation was also evaluated by ultrasound. After correction for confounding variables, testosterone was positively correlated to flow-mediated dilation (beta=0.277, P=0.03). Indeed, women in the lowest testosterone tertile had a flow-mediated dilation smaller than that in the highest tertile (P=0.02).

CONCLUSIONS: This result could suggest that the development of cardiovascular disease after menopause is due not only to estrogen decline but also to androgen decline. More studies are needed to evaluate the role of androgen replacement therapy on postmenopausal women with low level of this hormone.

Testosterone in Post Menopausal Women

An article in the medical journal Current Opinion in Obstetrics & Gynecology says that testosterone therapy is a promising option for treating women with HSDD (very low libido or desire)

Somboonporn W.Androgen and menopause.Curr Opin Obstet Gynecol. 2006 Aug;18(4):427-32.

From the article abstract:

PURPOSE OF REVIEW: Androgen therapy is being increasingly used in the management of postmenopausal women. The most common indication is to improve sexual function. The aim of this review is to evaluate current knowledge pertaining to testosterone and sexual function in postmenopausal women.

RECENT FINDINGS: The change of testosterone levels during the menopause transition remains controversial. A correlation of endogenous testosterone levels and sexual function is still inconclusive. A Cochrane Review and recent randomized control trials have, however, consistently demonstrated that short-term testosterone therapy in combination with traditional hormone therapy regimens improves sexual function in postmenopausal women, particularly surgically menopausal women with hypoactive sexual desire disorder.

An adverse effect on the lipid profile has been identified which appears to be mostly associated with oral methyltestosterone. Data for other effects of testosterone and long-terms risks are lacking. Testosterone may act in a variety of ways in different tissues. This is, however, an area that requires further investigation.

SUMMARY: Testosterone therapy is a promising option for treating women with hypoactive sexual desire disorder after surgical menopause. Two remaining questions need to be answer: who is most likely to benefit from testosterone therapy and what are the long-term health risks?

Testosterone For Women Studies and News

Testosterone and Libido in Post Menopausal Women
Researchers writing in the medical journal Gynecological Endocrinology say that there is emerging evidence that androgens are significant independent determinants affecting libido and satisfaction, as well as mood, energy and other components of women’s health.

Testosterone enhances libido and decreases depression
Researchers reporting in the Journal of Neuropsychiatry and Clinical Neurosciences say Testosterone enhances libido and decreases depression.

Schutter, et al. J Neuropsychiatry Clin Neurosci.2005; 17: 372-377. Depression Administration of Testosterone Increases Functional Connectivity in a Cortico-Cortical Depression Circuit.

From the abstract: “Increasing evidence suggests that the steroid hormone testosterone (T) enhances libido and decreases depression. Even a single administration of T (0.5 mg sublingually) in healthy young women is sufficient to enhance physiological sexual responsiveness….” Read the abstract

Testosterone For Libido Loss In Women
September 19, 2005’s Washington Post reported “a position statement from the North American Menopause Society (NAMS) and published in its journal, Menopause,” that testosterone therapy may aid many post-menopausal women dealing with loss of libido. You can read the Washington Post article here.

Study: An overview of testosterone deficiency and supplementation in women.
Davis SR, Androgen treatment in women. MJA 1999;170:545-549.

The researchers state: “Women reporting loss of libido may find physicians insufficiently empathetic, and a biological cause for sexual dysfunction in women is rarely sought. However, it is gradually becoming more accepted that androgen deficiency in women may underpin a variety of symptoms and pathophysiological conditions and that, in selected women, androgen replacement therapy is of clinical benefit.”

“Testosterone insufficiency in women: fact or fiction?”
Guay, A, Davis SR. Testosterone insufficiency in women: fact or fiction? World Journal of Urology 2002;20(2):106-10.

The researchers state: “Androgen deficiency is a true medical condition in both pre- and post-menopausal women. The most important recommendation is to listen to the patient and consider androgen deficiency when the symptoms are present, even if they seem non-specific…Treatment with androgens has to be monitored carefully because of the possible harmful effects of excessive levels of testosterone.”

Bone Loss and Testosterone in Women with Anorexia Nervosa
A study is being recruited, Anne Klibanski, M.D., Principal Investigator, by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and the National Center for Research Resources (NCRR) to determine among other things if low dose testosterone will be a benefit in preventing bone loss in women with Anorexia Nervosa.

From the abstract: “Women with Anorexia Nervosa have been found to have low bone density. The study will determine whether administration of low doses of a natural hormone, testosterone and/or risedronate, a medication to help prevent bone breakdown will improve or prevent bone loss in this condition.”

Testosterone Beneficial for Libido and Cholesterol
Researchers reviewing the current medical literature on the role of Testosterone in enhancing libido in post-menopausal women say; “The available evidence is that adding testosterone to estrogen therapy, with or without progestin, appears to be effective in improving sexual function in postmenopausal women and is associated with a reduction in high-density lipoprotein (HDL) cholesterol.”

The findings appear in The Cochrane Library, read the abstract and summary of this article .
