THE ESTROGEN DOMINANCE EFFECT Female problems seem to be on the rise. Between 40% and 60% of all women in the West suffer from PMS. In addition, women suffer from a plethora of symptoms, some menopausal and others not. Something quite serious seems to be happening. There is strong evidence that that the proper hormonal balance necessary for women's bodies to function healthily is being interfered with by a number of factors.
Research has shown that many women in their 30s - some even younger - will occasionally not ovulate during their menstrual month.[1] Without ovulation, no corpus luteum results and no progesterone is made. A progesterone deficiency ensues and several problems can result from this, one being the month-long presence of unopposed estrogen with all its attendant side effects.
A second major problem results from the interrelationship between progesterone loss and stress. Stress combined with a bad diet can induce cycles where ovulation does not occur. The consequent lack of progesterone interferes with the production of the stress-combating hormones, worsening stressful conditions that give rise to further anovulatory cycles and so continues the vicious cycle.
Another major factor contributing to this imbalance between estrogen and progesterone is the industrialized world now live in, immersed in a rising sea of petrochemical derivatives. They are in the air, food and water and include pesticides and herbicides (such as DDT, dieldrin, heptachlor, etc.) as well as various plastics (polycarbonated plastics found in babies bottles and water jugs) and PCBs. These estrogen-mimics are highly fat-soluble, not biodegradable or well excreted, and accumulate in the fat tissue of animals and humans. These chemicals have an uncanny ability to mimic natural estrogen and thus are given the name "xeno-estrogens" since, although they are foreign chemicals, they are taken up by the estrogen receptor sites in the body, seriously interfering with natural biochemical activity.
Extensive research is now revealing an alarming situation worldwide, created by the inundation of these hormone-mimics. In their book, Our Stolen Future, authors Theo Colburn of the World Wildlife Fund, Dianne Dumanoski of The Boston Globe, and John Peterson Meyers, a zoologist, have identified 51 hormone mimics, each able to unleash a torrent of effects such as reduced sperm production, cell division and sculpting of the developing brain. These mimics are not only linked to the recent discovery that human sperm counts worldwide have plunged by 50% between 1938 and 1990 but also to genital deformities, breast, prostate and testicular cancer, and neurological disorders.
Dr. John Lee, MD has discovered a consistent theme running through women's complaints of the distressing and often debilitating symptoms of PMS, peri-menopause and menopause: too much estrogen or, in other words, estrogen dominance. Now, instead of estrogen playing its essential role within the well-balanced symphony of steroid hormones in a woman's body, it has begun to overshadow the other players, creating biochemical dissonance. Even natural estrogens should not be prescribed unless it is clear that a deficiency exists.
Dr. Lee has been able to balance the estrogen-dominance effect through the use of transdermal natural progesterone cream. Natural progesterone, a cholesterol derivative, is made from wild Mexican yams or soybeans whose active ingredients are an exact molecular match of the body's own progesterone. It is interesting to note that in parts of Asia and South America where women eat either the wild yams or soybeans, the term "hot flash" doesn't even exist in their languages. They also rarely suffer from the host of female problems presently plaguing Western women. Supplementation with natural progesterone corrects the real problem: progesterone deficiency. Note, however, that the use of wild yam does not increase progesterone levels, and does not act as a precursor to progesterone in humans. Soy products contain phytoestrogens that act by altering tissue responses to estrogen.
Natural progesterone is not known to have any side effects; nor have any toxic levels been found to date. Natural progesterone increases libido, prevents cancer of the womb, protects against fibrocystic breast disease, helps protect against breast cancer, maintains the uterus lining, hydrates and oxygenates the skin, reverses facial hair growth and hair thinning, acts as a natural diuretic, helps eliminate depression and increase a sense of well being, encourages fat burning and the use of stored energy, normalizes blood clotting, and is a precursor to other important stress and sex hormones. Sometimes, even the two most prevalent menopausal symptoms - hot flashes and vaginal dryness - may disappear with applications of natural progesterone, though it may take many months.
Estrogen's role in osteoporosis is only a minor one. Estrogen replacement will reduce bone breakdown, but only progesterone increases new bone growth or deposition. Progesterone deficiency results in bone loss. In a three year study of 63 post-menopausal women with osteoporosis, women using transdermal progesterone cream experienced an average 7 to 8% bone mass density increase in the first year, 4 to 5% the second year, and 3 to 4% in the third year. Untreated women in this age category typically lose 1.5% bone mass density per year.[3] Dr. Lee believes that the use of natural progesterone in conjunction with dietary and lifestyle change can not only stop osteoporosis but can actually reverse it - even in women aged over 70.
It is important to make the distinction between natural progesterone that is produced by the body and the synthetic progesterone analogues classified as progestins, such as Provera, Duphaston and Primulut. There is a big difference between the two in their effect on the body, although doctors most often use their names interchangeably.
Since natural progesterone is not a patentable product, the pharmaceutical companies have altered it to produce synthetic progestins commonly used in contraceptives and HRT. Synthetic progestins, because they are not exact replicas of the body's natural progesterone, unfortunately create a long list of side effects, some of which are quite severe. A partial list includes headaches, depression, fluid retention, increased risk of birth defects and early abortion, liver dysfunction, breast tenderness, breakthrough bleeding, acne, hirsutism (hair growth), insomnia, edema, weight changes, pulmonary embolism and premenstrual-like syndrome.[4]
Most importantly, progestins lack the intrinsic physiological benefits of progesterone, thus they cannot function in the major biosynthetic pathways as progesterone does and they disrupt many fundamental processes in the body. Progesterone is an essential hormone that also plays a part in the development of healthy nerve cells and brain and thyroid function. Progestins tend to block the body's ability to produce and utilize natural progesterone to maintain these life promoting functions.
Without adequate knowledge, education and access to natural products, women have been easy prey to the powerful campaigns of the multinational drug companies that have convinced doctors as well as governments of their claims. It is becoming more evident that women's interests are not always best met through such a biased approach. It is also not unusual for profits to take precedence over health and well being. The last thing a woman needs is to have her natural bodily functions denigrated to deficiency diseases - thus necessitating ongoing medical attention.
The greatest weapon against compliance and ignorance is knowledge. It's time to ask poignant questions of your health provider, to demand answers and to be willing to investigate safe, alternative approaches. It is apparent that women will need to participate in educating their doctors about the other choices that exist as well as the ones that they prefer. Certainly, women have it well within their own power not only to find safe, natural and effective ways to heal themselves but to live long, full lives, preserving their vitality, youthfulness and health.
Effects of Estrogen Dominance - When estrogen is not balanced by progesterone, it can produce weight gain, headaches, bad temper, chronic fatigue and loss of interest in sex - all of which are part of the clinically recognized premenstrual syndrome.
- Not only has it been well established that estrogen dominance encourages the development of breast cancer thanks to estrogen's proliferative actions, it also stimulates breast tissue and can trigger fibrocystic breast disease - a condition which wanes when natural progesterone is introduced to balance the estrogen.
- Excess estrogen implies a progesterone deficiency. This, in turn, leads to a decrease in the rate of new bone formation in a woman's body by the osteoblasts - the cells responsible for doing this job. Although most doctors are not yet aware of it, this is the prime cause of osteoporosis.
- Estrogen dominance increases the risk of fibroids. One of the interesting facts about fibroids is that, regardless of the size, fibroids commonly atrophy once menopause arrives and a woman's ovaries are no longer making estrogen. Doctors who commonly use progesterone with their patients have discovered that giving a woman natural progesterone may cause fibroids to atrophy.
- In estrogen-dominant menstruating women where progesterone is not peaking and falling in a normal way each month, the ordered shedding of the womb lining doesn't take place. Menstruation becomes irregular. This condition can usually be corrected by making lifestyle changes and using a natural progesterone product. It is easy to diagnose by having a doctor measure the level of progesterone in the blood at certain times of the month.
- Endometrial cancer (cancer of the womb) develops only where there is estrogen dominance or unopposed estrogen. This, too, can be prevented by the use of natural progesterone. The use of the synthetic progestins may also help prevent it, which is why a growing number of doctors no longer give non-human estrogens without combining them with progesterone drug during HRT. However, all synthetic progestins have side effects.
- Water logging of the cells and an increase in intercellular sodium, which predispose a woman to high blood pressure or hypertension, frequently occur with estrogen dominance. These can also be side effects of progestins use. A natural progesterone cream often resolves this problem.
- The risk of stroke and heart disease is increased dramatically when a woman is estrogen-dominant. [Leslie Kenton, Passage to Power, Random House, UK, 1995]
Anti-aging Benefits of Natural Progesterone- Progesterone is a primary precursor in the biosynthesis of the adrenal corticosteroids. Without adequate progesterone, synthesis of the cortisones is impaired and the body turns to alternate pathways. These alternate pathways have masculine-producing side effects such as long facial hairs and thinning of scalp hair. Further impaired corticosteroid production results in a decrease in the ability to handle stress, e.g., surgery, trauma or emotional stress.
- Many peri- or post-menopausal women with clinical signs of hypothyroidism, such as fatigue, lack of energy, intolerance to cold, are actually suffering from unrecognized estrogen dominance and will benefit from supplementation with natural progesterone.
- Estrogen and most of the synthetic progestins increase intracellular sodium and water uptake. The effect of this is hypertension. Natural progesterone is a natural diuretic and prevents the cell's uptake of sodium and water, thus preventing hypertension.
- Whereas estrogen impairs homeostatic control of glucose levels, natural progesterone stabilizes them. Thus, natural progesterone can be beneficial to both those with diabetes and those with reactive hypoglycemia. Estrogen should be contraindicated in patients with diabetes.
- Thinning and wrinkled skin is a sign of lack of hydration in the skin. It is common in peri- and post-menopausal women and is a sure sign of hormone depletion. Both estrogen and progesterone restores skin hydration.
- Progesterone serves a role in keeping brain cells healthy. A disorder such as premature senility (Alzheimer's disease) may be, at least in part, another example of disease secondary to progesterone deficiency.
- Progesterone is essential for the healthy development of the myelin sheath which protects the nerve cells. Low progesterone levels lead to recurring aches and pains.
- Progesterone creates and promotes an enhanced sense of emotional well being and psychological self-sufficiency.
- Progesterone is responsible for enhancing the libido. [John R. Lee, M.D., Slowing the Aging Process with Natural Progesterone, BLL Publishing, CA, USA, 1994, p.14]
The hormone issue is a complicated one. There are three types of natural estrogen, and multiple degradation pathways and metabolites. Depending on the area of concern, a skilled natural doctor should be able to recommend those tests which will yield the most information, and guide you into balance. While a therapeutic trial of progesterone may help a condition of estrogen dominance, specific laboratory testing on a doctor's recommendation should be conducted prior to hormone replacement. Blood, saliva, or urine measurements may be made. Your doctor should be aware that the timing of specimen collection in relation to your cycle is important in progesterone testing. The best time is day 21 - 24 of your cycle (sooner if cycle is shorter and later if cycle is longer). If progesterone levels are normal, elevated estrogens can be reduced by means other than progesterone use.
The need for testing is seen in the situation of two menopausal women having similar symptoms but one with elevated estrogens (or an imbalance of estrogens) and the other with low estrogens. Both may have normal or low levels of progesterone. Giving natural estrogen to a woman in menopause seems the logical thing to do, but may make the situation worse if her levels are already too high. Giving a women low in estrogen, more progesterone won’t solve the underlying deficiency.
Female hormone imbalances can manifest in many and diverse symptoms. More specific suggestions regarding individual hormone levels may be made elsewhere in this report.
You can develop a clearer understanding of the nature of your condition and the interplay of female hormones by reading an informative book such as Natural Hormone Balance by Uzzi Reiss, MD, or What Your Doctor May Not Tell You About Premenopause and What Your Doctor May Not Tell You About Menopause by John Lee, MD.

Conditions that suggest Low Progesterone or Estrogen Dominance: | |  | | | | Autoimmune | Multiple Sclerosis / Risk | Progesterone has been shown in animal studies to promote the formation of new myelin sheaths [Human Reproduction 2000 Jun;15 Suppl 1: pp.1-13, J Steroid Biochem Mol Biol 1999 Apr-Jun;69 pp.97-107, Mult Scler 1997 Apr;3 pp.105-12]
Physicians have known for years that pregnancy can suppress some forms of immune response, such as allergies. In the early and mid-1980s, several doctors observed that MS patients had fewer symptoms during pregnancy and post-partum recovery. This may be due to the high progesterone level in the blood of a pregnant woman. Progesterone tends to be anti-inflammatory. Progesterone therapy may therefore be useful for MS especially as a medical report noted the association between enlarged adrenal glands and MS. Progesterone, being a steroid, often helps the adrenals deal with inflammation.
Other studies have indicated that symptoms are worse during periods when the progesterone to estrogen ratio is low. |
| Diet |
Sugar Craving | Environment / Toxicity |
Copper Toxicity | Elevated estrogen levels often increase serum copper levels to more than double normal values, while at the same time red blood cell levels, where copper is important, may actually be lower. This may contribute to some of the psychological or other symptoms seen during pregnancy or with birth control pill use. |
| Hormones |
Low Testosterone Level | Testosterone is converted into estrogen naturally. When this conversion is overactive the result is too little testosterone and too much estrogen. High levels of estrogen also trick the brain into thinking that enough testosterone is being produced, thereby reducing the natural production of testosterone. |
Hirsutism
Low SHBG | Elevated estrogen levels stimulate SHBG production, increasing levels in the blood. |
Low Sex Drive | Loss of sex drive often correlates with a progesterone deficiency, not an estrogen deficiency. |
Hypothyroidism | Progesterone increases sensitivity of estrogen receptors, and can therefore redirect estrogen activity and inhibit many of unopposed estrogen's undesirable side-effects, which includes interference with thyroid hormone activity. |
| Lab Values |
Low Total Cholesterol | Cholesterol is the raw material used to make progesterone, and is therefore its immediate precursor. |
| Mental |
Anxiety
Panic Attacks | It has been reported that women with low progesterone levels experience less intense or less frequent panic attacks after progesterone supplementation. In some cases, sublingual progesterone in olive oil has produced immediate benefit. |
| Metabolic |
Edema (Water Retention) | Progesterone has also been used in the treatment of idiopathic edema under the premise that some women with idiopathic edema either do not ovulate or have a luteal phase deficiency.
Ovarian function was investigated in 30 women with postural idiopathic edema by measuring plasma estradiol and progesterone levels between the 21st and 23rd days of the menstrual cycle. Plasma progesterone concentrations were found to be lower than 5ng/ml in 53% of the cases and lower than 10ng/ml in 83%. The ovarian dysfunction most frequently observed was inadequate corpus luteum, i.e. progesterone deficiency with normal plasma estradiol levels. In virtually all patients the initial disorder in capillary permeability, as evaluated by Landis' test, was fully corrected by progesterone administered orally. However, clinical improvement was less marked with treatments of short duration (2-3 consecutive cycles). In view of the complex cause of the disease, combined treatments in which progesterone might well play the major role are usually required. [Presse Med 1983 Dec 10;12(45): pp.2859-62 (translated)] |
| Musculo-Skeletal |
Torn, Weak, or Relaxed Ligaments or Tendons | It is important for females, who want to keep their ligaments and tendons strong, to keep progesterone levels at a maximum level. Progesterone stimulates the injury healing process in connective tissue by encouraging osteoblast and fibroblast proliferation, thus encouraging bone and soft tissue growth. Progesterone has been shown to increase collagen synthesis and decrease hydroxyproline concentrations in postmenopausal women. Progesterone, therefore, has a direct effect on preventing collagen breakdown. |
| Organ Health |
Gallbladder Disease | Skin-Hair-Nails |
Cold Hands and Feet | Cold hands and feet, often caused by low thyroid function, may be a symptom of estrogen excess or low progesterone influencing thyroid function. |
Female Hair Loss | Symptoms - Immune System |
General fungal/yeast infections | Tumors, Benign |
Fibroids | Tumors, Malignant |
Breast Cancer | See the link between Progesterone Low and Increased Risk of Breast Cancer. |
| Uro-Genital |
Endometriosis | Current scientific theory points to estrogen dominance as a major factor in endometriosis. Bringing progesterone and estrogen into natural balance will frequently result in symptom relief and, on occasion, even shrink endometrial tissue. This usually means using natural progesterone, either orally or as a cream and avoiding the use of or excessive exposure to estrogen. |
Premenstrual Syndrome / PMDD
Menorrhagia (Heavy Periods) | In a normal menstrual cycle, estrogen and progesterone regulate the buildup of the endometrium (uterine lining of blood and tissue), which is shed each month during menstruation. Menorrhagia can occur because of an imbalance between estrogen and progesterone. As a result of the imbalance, the endometrium keeps building up resulting in heavy bleeding when it is eventually shed. Since hormone imbalances are often present in adolescents and in women approaching menopause, this type of menorrhagia (dysfunctional uterine bleeding) is fairly common in these groups. |
Premenstrual Syndrome PMS A (Anxiety)
Metrorrhagia
Fibrocystic Breast Disease | FBD may be caused by excessive estrogenic stimulation of the breasts due to abnormal hormone levels or by an exaggerated response by hypersensitive tissues to normal hormone levels. |
Susceptibility To Miscarriages | Levels of progesterone rise every month after ovulation, preparing the lining of the uterus for pregnancy. In a non-pregnant menstrual cycle, progesterone levels rise after ovulation and fall just before a woman gets her menstrual period. When pregnancy occurs, the progesterone level should remain elevated. The ovaries produce the majority of progesterone through most of the first trimester, but eventually the placenta takes over production of the hormone by about the tenth week of pregnancy.
While there is no evidence proving the effectiveness of supplementation for women with low progesterone in early pregnancy, there doesn't seem to be any concrete evidence against it either.
Low progesterone in pregnancy is definitely associated with miscarriage, but the reason why is controversial. Levels that are too low could cause miscarriage if the uterus is not ready to support a pregnancy, perhaps because the ovaries have problems producing enough progesterone for some reason.
On the other hand, many doctors believe that low progesterone merely means that a miscarriage is impending for other reasons. With this line of thinking, the low levels are the first sign that the body is preparing to miscarry a pregnancy that has already failed for other reasons, such as chromosomal abnormalities in the developing baby, and progesterone supplementation is useless. |
Vaginitis/Vaginal Infection | Yeast infections are more common among women with increased levels of estrogen. This is seen in those who use estrogen-containing birth control pills and among women who are pregnant. The increased hormone level causes changes in the vaginal environment that make it a media for fungal growth and nourishment. |
|
| |  | |  |
Risk factors for Low Progesterone or Estrogen Dominance: | |  | | | | Autoimmune | Hyperthyroidism | Elevated estradiol and depressed bioavailable testosterone have been cited as the cause of sexual dysfunction common in hyperthyroid individuals. |
| Hormones |
Low Adrenal Function / Adrenal Insufficiency
Low Melatonin Level | One of melatonin's roles is the reduction of estrogen production in the body, and probably also reduction of the number of estrogen receptors. Studies have shown that the protective, estrogen-reducing effects of melatonin are significantly reduced by excessive exposure to light (including late night TV viewing) and probably electromagnetic fields, chemical pollutants such as pesticides and fungicides, and many commonly prescribed drugs, such as beta blockers for heart disease, high blood pressure and headaches. |
Counter-indicators:
Hyperprolactinemia | Hypothalamic PIF suppression can occur as a result of excessive estrogen intake, from oral contraceptives for example. Prolactin also stimulates the secretion of progesterone, which has, as this hormone’s name indicates, an important function in gestation. |

Stress | Stress increases cortisol production; cortisol blockades (competes for) progesterone receptors. Additional progesterone is required to overcome this blockade. |

Low Progesterone or Estrogen Dominance suggests the following may be present: | |  | | | | Nutrients | EFA (Essential Fatty Acid) Type 3 Requirement | Flax seeds and flax seed oil (when specifically prepared) contain high amounts of lignins. Lignins help to maintain a healthy balance between the various estrogens. By binding to estrogen receptor sites, the stronger (less healthy) form of estrogen is blocked, with the effect that there is less cell stimulation and it is more readily removed from the body. There is a specific product called Brevail that is designed to reduce the consequences of low progesterone or elevated estrogens. Such a product may not be necessary if you are already getting your lignins from flax. |

| Risks |
Cancer / Risk Reduction - General Measures | See the link between Progesterone Low and Increased Risk of Breast Cancer. |
Increased Risk of Breast Cancer | There is evidence that natural progesterone has an important role in breast cancer treatment and prevention. A study conducted in 1981 at Johns Hopkins University revealed that when a group with a low progesterone level was compared with a normal-level progesterone group, it was found that the occurrence of breast cancer was 5.4 times greater in the women in the low progesterone group. That is, the incidence of breast cancer in the low progesterone group was over 80% greater than in the normal progesterone group. When the researchers looked at the low progesterone group for all types of cancer, they found that these women experienced a tenfold increase in all malignant cancers, compared to the normal group.
In a 1995 study published in the Journal of Fertility and Sterility, researchers found that women using a topical progesterone cream had dramatically reduced breast cell multiplication rates compared to women using either a placebo or estrogen. This exciting study demonstrated that natural progesterone creams impressively decreased breast cell proliferation rates. (27) [ Sellman, Sherrill, Hormone Heresy: What Women MUST Know About Their Hormones, GetWell International, USA, 1997, pages 107 - 108] |
Increased Risk of Endometrial Cancer | High levels of estrogen without opposing progesterone can increase the risk of endometrial cancer. Using estrogen replacement therapy without taking progesterone or progestins is also related to a greater risk for endometrial cancer. |

Recommendations for Low Progesterone or Estrogen Dominance: | |  | | | | Botanical | Vitex | Vitex increases luteinizing hormone production while inhibiting the release of follicle stimulating hormone, leading to an indirect increase in progesterone and a normalization of prolactin levels. If taken regularly for several months, it helps to restore hormonal balance and alleviate PMS symptoms. |
Evening Primrose Oil / GLA
Not recommended:
Ginseng, Korean - Chinese / Asian (Panax ginseng) | It must be noted that Panax ginseng has been proven to have a mild estrogen-promoting activity in some women and would thus would be contraindicated where estrogen is already excessive, as may be the case with PMS or breast cancer. Eleuthero ginseng is not estrogen-promoting. Panax ginseng can cause insomnia, hypertension and muscle tightness if taken in excess. |
| Extract |
DIM (di-indolmethane)/I3C (Indole-3-Carbinol) | DIM encourages the conversion of estrogens to safer forms and helps reduce elevated levels. |
| Hormone |
Progesterone | Estrogens and progesterone tend to be antagonistic hormones, each balancing the other. When progesterone levels are low, it can seem as though estrogen levels are too high, which may or may not be the case. |
Estrogen-balancing Medications | Before using estrogen balancing medications whether natural or not, laboratory testing should be conducted to confirm elevated levels. |
DHEA | Lab Tests/Rule-Outs |
Test / Monitor Hormone levels | Nutrient |
TMG (Tri-methyl-glycine) / SAMe | TMG converts to S-adenosyl methionine (SAMe, an activated form of methionine) in the body. SAMe assists in the breakdown of estrogens. |
