Estrogen Deficiency Test
Assess your estrogen levels using this questionnaire inspired by the work of Dr. Thierry Hertoghe. This test is intended for women. Estrogens are essential for women's health: skin, hair, bones, mood, fertility and cardiovascular protection.
Estrogens are the quintessential female hormones, produced mainly by the ovaries but also in small quantities by the adrenal glands and adipose tissue. They govern femininity in all its dimensions: skin, hair, breasts, body shape, fertility, mood, bone density and cardiovascular protection. Their decline begins as early as perimenopause (often around ages 40-45) and accelerates at menopause, leading to symptoms that can profoundly impair quality of life: hot flashes, skin and vaginal dryness, hair loss, wrinkles, mood disturbances and bone fragility. Dr. Thierry Hertoghe, a Belgian endocrinologist and president of the World Society of Anti-Aging Medicine, has devoted a large part of his research to female hormones. His clinical approach makes it possible to identify an estrogen deficiency through characteristic physical signs, sometimes well before estradiol testing confirms the decline. This questionnaire is inspired by his work and his Atlas of Hormonal Medicine.

Understanding the role of estrogens
Estrogens comprise three main hormones: estradiol (E2), the most potent and abundant form during reproductive years, estrone (E1) which predominates after menopause, and estriol (E3), the gentlest form, produced in large quantities during pregnancy. Ovarian production is ensured by the granulosa cells of ovarian follicles, but adipose tissue and adrenal glands also contribute via the aromatase enzyme which converts androgens to estrogens. These hormones act throughout the body through two types of receptors: alpha receptors (ER-alpha), concentrated in reproductive tissues (uterus, breasts, ovaries), and beta receptors (ER-beta), present in the brain, bones and cardiovascular system. Their protective functions are considerable: they inhibit osteoclast activity (bone protection), promote nitric oxide and HDL production (cardiovascular protection), stimulate collagen, elastin and hyaluronic acid synthesis (skin quality) and support serotonin and BDNF production (brain and mood protection). The natural decline in ovarian production begins in perimenopause, generally between ages 40 and 50, and accelerates at menopause when ovarian follicles are depleted.
Monitoring markers
From a clinical perspective according to Hertoghe, good estrogenic status is reflected in supple and well-hydrated skin, firm breasts, thick and shiny hair, a regular menstrual cycle (between 27 and 31 days) and good vaginal lubrication. These clinical signs constitute your first daily monitoring tool: any progressive change in these parameters may signal the beginning of hormonal decline even before blood tests confirm it. If you wish to verify your status biologically, the key markers are estradiol (E2) measured on day 3 of the cycle (follicular phase, normal values between 30 and 100 pg/mL) or on day 21 (luteal phase, between 50 and 200 pg/mL), FSH (follicle-stimulating hormone, which rises when the ovaries struggle to produce sufficient estrogens) and LH (luteinizing hormone). The E2/FSH ratio is particularly informative: a low ratio indicates compensatory pituitary effort against less responsive ovaries. Anti-müllerian hormone (AMH) allows assessment of ovarian reserve and better anticipate the timing of hormonal transition.
Daily prevention
Maintain a sufficient percentage of body fat, as adipose tissue is an important site of estrogen production via the aromatase enzyme: a body mass index that is too low (below 18.5) can compromise your hormone production, particularly after age 40. Regularly incorporate foods rich in phytoestrogens into your diet: ground flaxseeds (2 tablespoons per day), fermented soy (tempeh, miso, natto) and legumes provide isoflavones and lignans that exert gentle modulatory support on estrogenic receptors. Omega-3s from small fatty fish (sardines, mackerel, anchovies) contribute to cell membrane fluidity and support hormonal communication. Reduce your exposure to xenoestrogens (endocrine disruptors present in plastics, pesticides, conventional cosmetics and certain food packaging) that disrupt hormonal balance by binding to estrogenic receptors. Regular physical exercise, particularly walking, yoga and light weight training, promotes healthy hormone metabolism and helps maintain bone density protected by estrogens.

Physiopathology of estrogen deficiency
Estrogen deficiency results primarily from the gradual depletion of the ovarian follicular reserve: each woman is born with approximately 1 to 2 million follicles, 300,000 to 400,000 remain at puberty, and this stock decreases inexorably until menopause. In perimenopause, the remaining follicles respond less well to FSH stimulation, which causes compensatory elevation of this pituitary hormone: FSH rises to try to stimulate increasingly unresponsive ovaries. A frequent paradox of this period is relative estrogenic dominance: cycles become anovulatory (no ovulation, therefore no corpus luteum, therefore no progesterone), creating an excess of fluctuating estrogens relative to collapsed progesterone. At confirmed menopause, estradiol (E2) drops by more than 90%, and residual estrogen production comes essentially from the conversion of adrenal androgens to estrone (E1) by aromatase in adipose tissue. The consequences of this drop are multisystemic: hot flashes result from dysregulation of the hypothalamic thermoregulatory center, bone loss accelerates through reactivation of osteoclasts, vaginal and urinary atrophy sets in, cardiovascular risk increases (loss of protective effect on nitric oxide and HDL), mood deteriorates through serotonin drop, and cognitive functions may decline through decreased BDNF (brain-derived neurotrophic factor).
Health markers vs laboratory markers
Among the clinical signs described by Hertoghe, small vertical wrinkles above the upper lip are considered virtually pathognomonic for estrogen deficiency: this perioral collagen loss is an early and highly specific visual marker. Sagging of the breasts reflects the loss of firmness of glandular and connective tissue under the influence of hormonal decline. The appearance of facial hair (facial hirsutism) reflects relative androgenic dominance that sets in when estradiol no longer counterbalances adrenal androgens. Dry and irritated eyes, hot flashes, chronic fatigue, depression, light or absent periods and a cycle less than 27 days or more than 31 days complete the clinical picture. From a biological perspective, estradiol (E2) is the central marker: in the follicular phase (day 3) normal values are between 30 and 100 pg/mL, at the ovulatory surge between 200 and 400 pg/mL, in the luteal phase between 50 and 200 pg/mL, and at menopause the level drops below 30 pg/mL. FSH above 40 IU/L confirms menopause, and the E2/progesterone ratio on day 21 of the cycle assesses overall hormonal balance. Anti-müllerian hormone (AMH) reflects remaining ovarian reserve, and SHBG (sex hormone-binding globulin) modulates the bioavailable fraction of sex hormones.
Phytoestrogenic diet
Phytoestrogens are plant compounds capable of binding to estrogenic receptors and exerting a gentle modulatory effect, particularly useful during periods of hormonal decline. Isoflavones from fermented soy (tempeh, miso, natto) are the best studied: they preferentially bind to ER-beta receptors (brain, bones, heart) without excessively stimulating ER-alpha receptors (breasts, uterus), which explains their favorable safety profile. Lignans from flaxseeds (2 tablespoons ground per day) constitute another major source of phytoestrogens and are converted by intestinal flora into enterolactone and enterodiol, two metabolites with gentle estrogenic activity. Coumestans from alfalfa complete the trio of dietary phytoestrogens. Omega-3s from small fatty fish support cell membrane fluidity and exert an anti-inflammatory action that promotes healthy hormonal function. Cruciferous vegetables (broccoli, cabbage, cauliflower) provide DIM (di-indolylmethane) and I3C (indole-3-carbinol) which direct estrogen metabolism toward the protective 2-hydroxy pathway rather than the deleterious 16-hydroxy pathway. Foods rich in vitamin E (almonds, sunflower seeds, hazelnuts) protect cell membranes and help reduce hot flashes, while avoiding xenoestrogens (BPA in plastics, phthalates, pesticides, plastic food packaging) prevents overloading receptors with disruptive molecules.
Targeted supplementation
DIM (di-indolylmethane) at 100-200 mg per day promotes healthy estrogen metabolism by directing conversion toward protective 2-hydroxy metabolites rather than potentially harmful 16-hydroxy metabolites, which is particularly useful in perimenopause where estrogen metabolism is disrupted. Natural vitamin E (mixed tocopherols) at 400 IU per day has demonstrated in several studies a reduction in hot flashes of nearly 50% and protects cell membranes against the oxidative stress increased by hormonal decline. Evening primrose or borage oil at 1-2 g per day provides gamma-linolenic acid (GLA) that supports hormonal balance and improves the quality of skin and mucous membranes dried by estrogen deficiency. Calcium at 1000 mg per day (in citrate form for better absorption) combined with vitamin D at 2000-4000 IU per day forms the foundation of bone protection, as the loss of estrogenic protection exposes you to accelerated bone resorption. Magnesium bisglycinate at 300 mg per day participates in more than 300 enzymatic reactions and supports mood, sleep and muscle relaxation. Vitamin B6 in P5P form (pyridoxal-5-phosphate) at 25 mg per day contributes to prolactin regulation and neurotransmitter metabolism affected by estrogen decline.
Lifestyle
Weight-bearing exercise (brisk walking, weight training, dancing, stairs) is essential for maintaining bone density weakened by estrogen decline: mechanical stress stimulates osteoblasts and partially compensates for the loss of osteoclast inhibition. Maintain adequate body fat percentage, as excessive thinness (BMI below 18.5) worsens estrogen deficiency by reducing peripheral conversion of androgens to estrone by adipocyte aromatase: in perimenopause and menopause, adipose tissue becomes the main residual source of estrogens. Stress management is fundamental because cortisol directly competes with sex hormones through the pregnenolone steal phenomenon: under chronic stress, pregnenolone is diverted toward cortisol production at the expense of estrogens and progesterone. Sleep quality deserves special attention because melatonin supports ovarian function and sleep deprivation aggravates hormonal dysregulation: aim for 7 to 8 hours of sleep in complete darkness. Reducing exposure to endocrine disruptors involves concrete daily actions: prefer certified organic cosmetics, use glass containers rather than plastic, choose organic foods to limit pesticide residues and avoid heating food in plastic containers.
Female herbal hormone support
Sage (Salvia officinalis) is the reference plant for supporting estrogen deficiency: it contains diterpenes and flavonoids with estrogenic activity that remarkably reduce hot flashes and night sweats, often starting within days of use. Red clover (Trifolium pratense) is rich in isoflavones (genistein, daidzein, biochanin A, formononetin) that bind preferentially to ER-beta receptors and provide moderate estrogenic support without the risks associated with synthetic estrogens. Hops (Humulus lupulus) contain 8-prenylnaringenin, considered the most potent phytoestrogen identified to date, particularly effective against hot flashes and sleep disturbances. Dong quai (Angelica sinensis), called the female ginseng in traditional Chinese medicine, has been used for millennia as a female hormonal tonic to regulate the cycle and reduce symptoms of estrogen decline. Evening primrose oil (Oenothera biennis), rich in gamma-linolenic acid (GLA), supports mucous membrane suppleness and skin hydration affected by estrogen decline. In gemmotherapy, raspberry bud (Rubus idaeus) is the great female hormonal regulator, acting on the hypothalamic-pituitary-ovarian axis to harmonize hormone production, and blackcurrant bud (Ribes nigrum) supports the adrenal glands which take over estrogen production after ovarian decline.

Physiopathology of severe estrogen deficiency
A score this high reflects a major collapse in estrogen production that goes beyond simple physiological decline. The ovarian follicular reserve is probably exhausted or in terminal decline: FSH reaches very high values (often above 40 IU/L) in the pituitary's desperate attempt to stimulate ovaries that no longer respond. Estradiol (E2) drops below 30 pg/mL, leaving only peripheral conversion of estrone (E1) by aromatase in adipose tissue and adrenal glands as a residual estrogen source, production far insufficient to maintain protective functions. The consequences are systemic and worsen over time: hot flashes reflect profound dysregulation of the hypothalamic thermoregulatory center deprived of its estrogenic signal, bone loss accelerates dangerously through massive reactivation of osteoclasts (risk of losing 2 to 5% of bone mass per year in the first 5 years post-menopause), vaginal and urinary atrophy progresses, cardiovascular risk increases significantly (protective HDL decreases, arterial stiffness develops), and serotonin and BDNF collapse explains depression, anxiety and cognitive decline frequently observed. This situation justifies comprehensive, intensive and professional management.
Mandatory biological assessment
At this level of symptoms, hormonal testing is no longer optional but absolutely essential to confirm the deficiency, measure its severity and guide management. Request without delay from your physician a comprehensive assessment including: estradiol (E2) whose value below 30 pg/mL confirms menopause, FSH (above 40 IU/L at confirmed menopause), LH, E2/FSH ratio, anti-müllerian hormone (AMH) to assess remaining ovarian reserve, and SHBG which modulates hormonal bioavailability. Given the probable length of the deficiency, bone density testing (DEXA) is strongly recommended from age 50 or at confirmed menopause to assess impact on bone density: silent bone loss is one of the most dangerous consequences of estrogen deficiency because it only manifests at fracture stage. Cardiovascular assessment (complete lipid panel, blood glucose, high-sensitivity CRP, blood pressure) is also relevant because loss of cardiovascular estrogenic protection significantly increases risk of atherosclerosis and cardiovascular events after menopause. TSH and free T4 should be checked because the thyroid is frequently disrupted during major hormonal upheavals.
Enhanced dietary protocol
Faced with such marked deficiency, the dietary phytoestrogenic protocol must be intensified and systematized. Consume daily freshly ground flaxseeds (2 to 3 tablespoons per day) which constitute the most concentrated source of lignans, converted by intestinal flora into enterolactone with potent estrogenic activity. Incorporate fermented soy (tempeh, miso, natto) at 2 to 3 servings per week for regular isoflavone intake (genistein and daidzein) that bind to protective ER-beta receptors. Cruciferous vegetables (broccoli, cabbage, cauliflower, kale) should feature at every meal for their DIM and I3C content which direct residual estrogen metabolism toward the protective 2-hydroxy pathway. Foods rich in vitamin E (almonds, sunflower seeds, hazelnuts, wheat germ oil) and omega-3s (sardines, mackerel, chia seeds) should constitute the basis of your daily fat intake. Foods rich in boron (prunes, raisins, almonds, avocados) support bone metabolism and promote conversion of inactive estrogen forms. Rigorously eliminate all food-based endocrine disruptors: plastic packaging, canned foods with BPA lining, pesticides (choose organic), water in plastic bottles.
Enhanced supplementation
Natural vitamin E (mixed tocopherols) should be increased to 800 IU per day to maximize its effect on hot flashes and membrane protection, as studies show significant dose-response relationship at this deficiency level. DIM at 200 mg per day optimizes metabolism of residual estrogens toward protective pathways. Evening primrose or borage oil at 2-3 g per day provides gamma-linolenic acid (GLA) necessary to restore mucous membranes dried by estrogen deficiency (vaginal, ocular, skin). Calcium citrate at 1200 mg per day combined with vitamin D at 4000 IU per day and boron at 3 mg per day constitutes the essential bone-protective protocol against accelerated bone density loss. Magnesium bisglycinate at 400 mg per day supports mood, sleep and muscle cramps frequent in estrogen deficiency context. Vitamin B6 in P5P form at 50 mg per day, zinc at 15 mg per day and vitamin C at 1 g per day complete the protocol by supporting overall hormonal metabolism, collagen synthesis and immune function weakened by hormonal transition.
Lifestyle and emotional support
Weight-bearing exercise (weight training, weighted walking, dancing, stair climbing) becomes a first-line prescription to counter accelerated bone loss: aim for 30 to 45 minutes of weight-bearing exercise at least 4 times per week, as mechanical stress is the most powerful stimulus for bone formation outside of estrogens. Maintain adequate body fat percentage without excess (BMI between 22 and 27 at menopause) because adipose tissue is now your main residual source of estrogens via aromatase: very thin women often experience more severe menopause. Stress management through heart rate variability (3 times daily, 5 minutes), meditation or yoga is even more important because cortisol competes with sex hormones for pregnenolone substrate. Sleep must be protected with a cool room (64-66°F) to limit night sweats, complete darkness to optimize melatonin, and regular sleep time. Emotional and psychological support for this transition should not be minimized: menopause can be experienced as grief for fertility and youth, and therapeutic support (psychologist, support groups, sophrotherapy) helps navigate this stage with serenity. Discuss openly with your physician all available options, including bio-identical hormones (transdermal estradiol, micronized progesterone), because in cases of severe deficiency with significant impact on quality of life, this option deserves exploration.
Intensive herbal therapy
Sage (Salvia officinalis) should be taken 3 times daily (leaf infusion or standardized extract at each meal) to maximize its effect on hot flashes and night sweats: it is the most documented and most effective first-line plant against menopausal vasomotor symptoms. Hops (Humulus lupulus), through 8-prenylnaringenin (the most potent phytoestrogen known), provides significant estrogenic support and also promotes sleep, often severely disrupted by night sweats and hormonal deficiency. Red clover (Trifolium pratense) at 80 mg of isoflavones per day completes the phytoestrogenic protocol by targeting ER-beta receptors (bones, brain, heart) without overloading breast ER-alpha receptors. Dong quai (Angelica sinensis), the millenary female hormonal tonic from Chinese pharmacopeia, supports pelvic circulation and helps reduce vaginal dryness and residual cramping. In gemmotherapy, raspberry bud (Rubus idaeus) at 15 drops morning and evening acts as a regulator of the hypothalamic-pituitary-ovarian axis and remains relevant even at menopause to harmonize residual hormonal terrain. Blackcurrant bud (Ribes nigrum) actively supports adrenal glands which must compensate for ovarian failure, and coast redwood bud (Sequoiadendron giganteum) exerts a general tonic and bone-protective effect valuable in this context of global fragility.
