What To Expect During The Test
To carry out an estradiol test, a medical professional will take a blood sample from a persons arm or hand. They will clean the area and then look for a suitable vein.
They will use a needle to draw blood from the area, which they will then send to a laboratory for testing.
The results of an estradiol test vary from person-to-person and will indicate different things, depending on the individual. Many factors can affect what the results mean, such as age, sex, and health history.
Doctors measure estradiol levels in picograms per milliliter .
- In premenopausal females, normal estradiol levels are 30 to 400 pg/ml.
- In postmenopausal females, normal estradiol levels are 0 to 30 pg/ml.
- In males, normal estradiol levels are 10 to 50 pg/ml.
If the test results indicate low estradiol levels, they could signal one of the following:
- ovarian failure
- low estrogen levels due to rapid weight loss
- low levels of pituitary hormones
- failing pregnancy
- tumors in the ovaries, testicles, or adrenal glands
Pregnancy and a persons menstrual cycle can affect the results in the following ways:
- Estradiol levels are higher during pregnancy as the placenta produces estradiol.
- During the menstrual cycle, estradiol levels are highest during ovulation and lowest during menstruation.
In adolescents, high levels of estradiol could signal early puberty in girls and delayed puberty in boys.
Causes Of High Estrogen In Men
In the setting of Testosterone Replacement Therapy , we are much more likely to deal with increased estradiol levels, called hyperestrogenism.
There are many reasons why your body may be producing too much estrogen. For instance, if you suffer from obesity, your excess fat can actually start producing additional estrogen beyond what your body already produces.
While we occasionally do see elevated estrogen levels prior to starting treatment for Low T, this is most often a problem that arises because of higher testosterone levels achieved as the result of TRT thats practiced improperly, including the following poor practices:
- Your hormone levels are not being regularly or carefully measured
- Youre not receiving an aromatase inhibitor at appropriate levels
- Your medical provider isnt extremely careful about his or her methods
In these cases, much of the extra testosterone being introduced into your body can be converted into excess estradiol.
Estrogen Levels During Puberty
Usually starting between 8 and 13 in people with ovaries , a part of the brain known as the hypothalamus begins to produce the hormone GnRH, stimulating the ovaries and an increase in estrogen, which eventually results in a first period .
Breast buds a small amount of firm, tender breast tissue just under the nipple are often the first sign of puberty. This process is launched by estrogen, which sparks the fat in connective tissue to connect and bind, causing breast enlargement and the development of breast ducts. Estrogen is also involved in the growth of pubic and underarm hair, and like we mentioned above, the start of the menstrual cycle.

What Is A Normal Estrogen Level
Here are the normal ranges for estrogen according to the lab and also the range for where I would ideally like it to be:
Lab Range for day 3 in women: 60 824 pmol/L
Estimated Ideal Range for day 3 in women: 150-200 pmol/L
Estimated Ideal Range for midcycle: 1000-1500 pmol/L
Lab Range for estrogen in men: < 200 pmol/L
Estimated Ideal Range in men: 129-142 pmol/L
How To Fix Estrogen Deficiency
How to fix the problem depends on why its low. Factors that can cause low estrogen include:
Adrenal gland insufficiency or HPA axis dysfunction
Supporting the adrenal glands involves replenishing vital vitamins and minerals like vitamin C, B5, B6, magnesium, and zinc. Adaptogenic herbs like Schisandra, Rhodiola, Ashwagandha, and Reishi also help.
Hypothyroidism
Your thyroid may be low due to nutritional deficiency or a condition known as Hashimotos thyroiditis. Depending on the cause, the solution may be to support your thyroid with nutrients like copper, zinc, selenium iodine, and tyrosine. A word of caution, too much iodine can cause problems. Avoid supplementing unless you are under the supervision of a naturopathic doctor. Research suggests that Hashimotos may be due to latent infection. In which case, supporting healthy immune system function helps.
Post-menopause women do still produce a certain amount of estrogen. Maintaining healthy testosterone levels through weight training and adrenal gland support can ensure optimal levels after menopause.
Excessive androgens
If levels of male hormones or androgens are too high, they can suppress ovulation, thereby suppressing estrogen production. In this case, the solution is to reduce the androgen excess. We do this through diet, stress reduction, exercise, and natural remedies like inositol, black cumin seed, saw palmetto, and nettle root.
High prolactin
There are five typical reasons why prolactin can be too high:

Symptoms Of High Estrogen In Men
Although its called the female hormone, a mans body also makes estrogen. A healthy balance of estrogen and testosterone is important for sexual growth and development. When these hormones become imbalanced, your sexual development and function may be affected.
Symptoms of high estrogen in men include:
- Infertility. Estrogen is partly responsible for creating healthy sperm. When estrogen levels are high, sperm levels may fall and lead to fertility issues.
- Gynecomastia. Estrogen may stimulate breast tissue growth. Men with too much estrogen may develop gynecomastia, a condition which leads to larger breasts.
- Erectile dysfunction . Men with high levels of estrogen may have difficulty getting or maintaining an erection.

What To Do If Testosterone Or Estrogen Levels Are Out Of Normal Range
Treatment with our clinic using TRT or ERT is one of the safest and most effective ways to get testosterone and estrogen levels that are out of range back into range to avoid feeling symptoms that can impede upon quality of life. When testosterone or estrogen levels are out of normal range, a woman may start to feel very uncomfortable. She may lose her sexual drive, feel depressed, have terrible hot flashes and night sweats and feel old and unworthy.
Women need the right amount of both testosterone and estrogen in their bodies for the following reasons:
- Less hot flashes
- A stronger sexual libido and desire for intimate relations
- The elimination of vaginal dryness
- A stronger ability to fantasize
- Stronger skin elasticity
- Less facial wrinkles and crows feet
- Less saggy skin
- Healthier, stronger and thicker hair
- Nails that grow faster
- A more youthful looking appearance
- Much better emotional stability
- Less anxiety, tension and stress
- A stronger immune system against sickness
- A better ability to maintain a healthy weight
- A better ability to maintain a healthy looking physique
Association To Menstrual Cycle

Estrogen Levels Right Before And During Menopause
During the transitional stage before menopause, perimenopause, estrogen levels become erratic, with a preference toward elevation. As this first stage of menopause comes to a close, these levels become less erratic and begin to decline while LH and FSH start to largely increase. This overall lack of estrogen can result in vaginal dryness, loss of vaginal elasticity, and less blood supply to the genital area, as well as bone loss.
As estrogen levels drastically change in perimenopause, high levels can cause bloating, breast tenderness, and heavy bleeding. Once these levels become more consistently low, that can cause hot flashes, night sweats, mood changes, changes in fat distribution , insomnia, and fatigue. At the same time, menstrual cycles are also changing as a result, making periods less predictable and fertility decline as menopause progresses.
Blood Levels Of Estradiol
In most laboratories, serum estradiol levels range from 20 to 80 pg/mL during the early to midfollicular phase of the menstrual cycle and peak at 200 to 500 pg/mL during the preovulatory LH surge. During the midluteal phase, serum estradiol levels range from 60 to 200 pg/mL.32
Before puberty, serum estradiol levels are less than 20 pg/mL, indistinguishable from cases of hypogonadism. After menopause, estradiol levels fall to prepubertal levels the mean serum estradiol level is typically 10 to 20 pg/mL, and levels are lower than 10 pg/mL in women who have undergone oophorectomy.
In men, serum estradiol levels should be less than 40 pg/mL, but may be increased in several testicular and nontesticular diseases. Serum estradiol levels are relatively constant and, unlike testosterone, are unchanged with age.33 In men, it is important to measure serum estradiol with assays that are able to distinguish between low values.
Male serum estrone levels should be less than 60 pg/mL. The measurement of serum estradiol and estrone may be useful in the clinical evaluation of hypogonadism and gynecomastia. However, obesity is the most common cause of mildly increased levels of circulating estrogens in men.33

- other medical conditions you have
- how you react to the first dose
What Causes A Low Estrogen Level
There are several possible reasons why a woman might experience low estrogen production or levels.
First, if there is a low estradiol level coupled with high FSH levels and high LH levels, this can indicate a condition known as premature ovarian failure or primary ovarian insufficiency. This means that, even with proper hormonal stimulation, the ovaries are failing to produce a normal amount of estradiol. This can sometimes be due to a genetic condition, such as Turner syndrome, an autoimmune disorder, or exposure to certain toxins.
Second, if there is a low estradiol level coupled with normal or low FSH and LH levels, this can be due to a condition known as hypogonadotropic hypogonadism. This condition can occur because of severe stress, excessive alcohol intake, excessive exercise, or a problem with the pituitary gland in the brainâwhich stimulates the production of FSH and LH hormones.

Low Estrogen Levels And Weight Gain: Is There A Connection
Sex hormones, such as estrogen, influence the amount of fat in the body. Estrogen regulates glucose and lipid metabolism. If your estrogen levels are low, it can result in weight gain.
Research suggests that this may be why women approaching menopause are likely to become overweight. Being overweight can increase your risk for obesity, diabetes, and cardiovascular disease.
If your estrogen levels are low and its affecting your weight, speak with your doctor. They can assess your symptoms and advise you on next steps. Its always a good idea to try to eat a balanced diet and exercise as often as possible. Talk with your doctor about developing a diet and exercise plan thats right for you.
What Role Does Estrogen Play In Reproductive Health For Women Or Dfab
Estrogen, like all hormones, is a chemical messenger. It tells your body when to start and stop processes affecting your sexual and reproductive health. These processes cause important changes in your body.
Puberty
Estrogen levels rise during puberty. The increase leads to secondary sex characteristics like breasts and changes in overall body composition .
Menstrual cycle
Along with hormones made in your brain and progesterone, estrogen plays an important part in your menstrual cycle. These hormones coexist in a delicate balance to keep your periods regular. Estrogen plays a role in ovulation and thickens the lining of your uterus to prepare it for pregnancy.
Pregnancy & Fertility
Estrogen peaks in the days leading up to ovulation. This is your most fertile period. At the same time, estrogen thins your cervical mucus, a fluid sperm has to swim through to reach and fertilize an egg. These estrogen-induced changes make it easier for you to become pregnant if you have intercourse.
Regardless of where you are in your menstrual cycle, the presence of estrogen makes it more comfortable to have intercourse. It keeps your vaginal walls thick, elastic and lubricated, reducing pain associated with penetrative sex.
Menopause
The primary estrogen in your body changes from estradiol to estrone during menopause.

What Your Estrogen Total Test Results Mean
The total estrogen test measures the levels of three hormones: E1, E2 and E3. Individually tested, levels are dependent on tanner stages. These are the measure of development for children.
For estrone , interpreting results is based on the age and gender of the person being tested. Children have very high levels of this hormone at birth from day 1 and for a period of two weeks, after which levels fall significantly.
For boys and men, these are the normal E1 values, per tanner stage:
- Stage I: normal values are either undetectable or within the range of 0 to 16 pg/mL.
- Stage II: normal values either undetectable or within the range of 0 to 22 pg/mL.
- Stage III: normal values are between 10 and 25 pg/mL.
- Stage IV: normal values have to be between 10 and 46 pg/mL.
- Stage V: normal values have to be between 10 and 60 pg/mL.
For girls and women, normal estrone levels need to be as follows:
- Stage I: normal values are either undetectable or within the range of 0 to 29 pg/mL.
- Stage II: normal values are between 10 and 33 pg/mL.
- Stage III: normal values are between 15 and 43 pg/mL.
- Stage IV: normal values have to be between 16 and 77 pg/mL.
- Stage V: normal values have to be between 17 and 200 pg/mL.
For adult men, normal values are between 10 and 60 pg/mL. For adult women, levels depend on menopause. Premenopausal levels are between 17 and 200 pg/mL while postmenopausal levels are between 7 and 40 pg/mL.
For boys and men, these are the normal E2 values, per tanner stage:
The Connection Between Low T And Estrogen
Estrogen levels and testosterone levels are closely related. In fact, one of the primary causes of low estrogen is actually low testosterone.
Mens bodies produce estradiol, a form of estrogen, as a byproduct the breakdown of testosterone through an enzyme called aromatase. Aromatase is found in estrogen-producing tissue, such as the adrenal glands, the brain, fatty tissue, and even the testicles.
Estradiol is often referred to as E2 and is one hormone in a class of hormones called Estrogens. This class includes estradiol, estriol, and estrone, among others.
Estradiol is likely the main estrogen you need to worry about.
The production of estrogen in a male body is a completely normal and necessary process. Estrogen is required for the healthy physiologic functions of your brain and other important organs, including:
- Erectile function and sex interest
- Maintenance of bone health

Abnormalities In The Production Of Other Steroids
Abnormalities in the production of other steroids, particularly those that result in an absence of cortisol, are usually associated with inherited disorders of sex steroid metabolism.
Aromatase deficiency, which is not associated with cortisol abnormalities, usually results in masculinization to some degree in females, in addition to primary puberty failure. Males with aromatase deficiency may present with delayed puberty, delayed epiphyseal closure, and decreased bone density. Estradiol and estrone levels in persons with aromatase deficiency are undetectable or very low.
Various types of testicular feminization result from disorders involving androgen-signaling pathways and lead to female phenotypes in genetic males. In such individuals, estradiol and estrone levels exceed the reference range for males and typically rise into the reference range for females, while testosterone levels are also significantly elevated.
