Causes and Treatments of High Estrogen in Men


A lot of people associate estrogen as being a “female” hormone and testosterone as being a “male” hormone, but high estrogen in men is increasing.

The key to all hormones is having them in the right balance, and high estrogen in men can lead to a wide range of unwanted symptoms from weight gain to mood changes.

So this article looks at both the cause and treatment of high estrogen levels in men.

The symptoms of high estrogen in men can be similar to the symptoms of low estrogen, also you may have normal estrogen levels but low testosterone which will also cause similar symptoms.

When trying to treat any hormone imbalance the first thing that you must do is proper hormone testing, this tells us exactly what hormones are out of balance which takes the “guesswork” out of your treatment program.

Women with high estrogen should read this article.

Why Men Need Estrogen


There has not been a lot of research into why men need estrogen, but over the past few years, that is starting to change as researchers recognize that estrogen is important for health in other ways besides reproduction.

Men need a small amount of estrogen for a variety of reasons, both physical and neurological. It is unusual for men to be low in estrogen unless they are taking estrogen blockers like Arimidex, or there is a problem with the pituitary gland.

Benefits of Estrogen for Men

  • Estrogen is essential for bone health with low levels associated with osteoporosis
  • Estrogen is important for cardiovascular health, while high levels are associated with increased risk of stroke and heart disease, there is also an associated risk of heart disease with low estrogen
  • Estrogen is important for mood and brain function, there are many estrogen receptors in the brain and having the right balance can improve mood and decrease the risk of conditions like Alzheimer’s disease
  • Low estrogen can also cause insomnia and fatigue

Most men will not have an issue with low estrogen unless they are taking estrogen-blocking medications, this is why natural estrogen lowering treatments are safer with fewer side effects.

High estrogen levels are more of a problem for men, especially as they get older so let's look at the problem with high estrogen in men.

Signs and Symptoms of High Estrogen In Men


While the benefits of estrogen in men are important, you have a much greater chance of having high estrogen levels, and the chance of high estrogen in men increases with age and the amount of body fat that you have.

Noteworthy:  High estrogen will affect body composition, mood, and overall health so it is important to address.

High estrogen in men usually corresponds with lower testosterone levels which will make symptoms worse, this is another reason why testing is important to check if you have both high estrogen and/or low testosterone levels.

Symptoms of High Estrogen Levels:

  • Increased body fat - especially around the breasts and waist, and it is usually harder to lose weight, this excess body weight can be from increased fat and fluid retention
  • Low libido - this can be low sexual desire as well as erectile dysfunction and not being able to maintain an erection
  • Low mood - this can range from depression to just feeling flat.
  • Low energy levels - this includes fatigue and a lack of motivation, this will be worse with low testosterone as well as high estrogen levels
  • Insomnia - poor sleep can be because of frequent urination and night sweats
  • Prostate problems - high estrogen will lead to an enlarged prostate which will cause urination issues and also an increased risk of prostate cancer
  • Cardiovascular disease - both strokes and an increased risk of heart disease occurs with high estrogen in men in particular

So as you can see high estrogen levels in men can leave you feeling crappy, as well as being out of shape with increased weight and man boobs - and even if you don’t care too much about how you look it is going to increase your risk of heart disease, diabetes, and dementia.

If you are ticking too many of the high estrogen symptoms let’s look at what is causing high estrogen in men, then we can look at treatment, while the treatment will be similar to women with excess estrogen there is going to be a couple of differences.

The Causes of High Estrogen in Men


Estrogen levels in men will usually increase as we age, mainly because of an increase in the aromatase enzyme and there are many different reasons for this with higher levels of body fat being the number one problem.

The common causes of high estrogen levels in men:

  • 1
    Aging - While getting older is inevitable it will often lead to an increase in your estrogen levels and a gradual decline in your testosterone levels. Getting older is inevitable but increased estrogen levels do not have to be, it is just that you cannot drink as much alcohol as you did when you were younger, or eat the same foods as your body and hormones will not be so forgiving.
  • 2
    Aromatase enzyme - The aromatase enzyme will lead to an increase in the conversion of testosterone to estrogen, which is exactly what you do not want to happen. The aromatase enzyme often increases with aging but it will also increase with increased body fat, alcohol, processed foods, and medications. The good thing is that there are a number of beneficial supplements as well as dietary changes that you can do to lower the aromatase enzyme.
  • 3
    Testosterone replacement therapy - Often when men present to the doctor with low libido or erectile dysfunction they will have their testosterone levels checked, and if low given a prescription for testosterone. One of the number one reasons for low testosterone is poor dietary and lifestyle habits which leads to an increase in aromatase enzyme, leading to an increase in conversion of testosterone to estrogen. So unless you address the underlying cause of why the testosterone is low just taking more testosterone can lead to an increase in conversion to estrogen and all of the side effects that come with that.
  • 4
    Stress - A life with stress is normal, but it needs to be manageable stress. An increase of stress will also increase aromatase enzyme and the conversion of testosterone to estrogen, and some of the causes of stress are diet, lack of sleep, relationship and work stress, overtraining or even a lack of exercise. High cortisol levels are caused by high physical and emotional stress, this can easily be tested to see if it is an underlying cause of high estrogen.
  • 5
    Diet - What you eat can affect your estrogen levels in a number of different ways, a diet high in refined carbohydrates will lead to insulin resistance and increased body fat. Not only increased body fat can cause an increase in aromatase enzyme but estrogen,  yes, fat increases estrogen production! It is not just an increase in refined carbohydrates that will lead to weight gain but an increase in calories in general, often men may eat “ok” but get an increase in calories from alcohol, juices, flavored milk, and soda.
  • 6
    Body Fat - As I just mentioned increased body fat, especially around the waist will increase your estrogen levels in men as the fat produces estrogen. If you have increased body fat around the waist there is a very high chance that you are going to have high estrogen levels, and all of the risk factors that I have mentioned like diet, stress, and simply getting older is going to be a cause of this.
  • 7
    Environmental toxins - Also known as xenoestrogens or endocrine disruptors, these are chemicals that are found in plastics, personal care products, and throughout the environment in general that can either have an estrogen-like effect on your hormones, or they increase the levels of your aromatase enzyme.
  • 8
    EMFs are another type of environmental toxin, and these days we cannot avoid them, but there are steps we can take to reduce our exposure to EMFs and this article describes how EMFs affect testosterone

      Genetics can also influence the way your body detoxifies hormones, the best way to find out more about how your genes can affect your health is with a SelfDecode genetic test - you can read more about SelfDecode here.

The Best Test to Measure Your Sex Hormones

The signs and symptoms of high estrogen can be similar to low estrogen or simply low testosterone, so before you start to try and lower your estrogen levels a good idea would be to test your sex hormones as this takes out the guesswork.

Men can commonly have high cortisol levels which can contribute to high estrogen and low testosterone symptoms, high cortisol can also produce similar symptoms to high estrogen in men so testing is important.

There are 3 main ways of assessing your estrogen levels and they all have their pros and cons. Read the article "the best way to test hormones" for more detail.

3 Types of Estrogen Testing

Blood testing

Blood testing which is often done by your doctor can be a great way to assess your levels of estradiol which is the more potent form of estrogen, but estriol and estrone levels are often not tested for. One of the downsides to blood testing is that it only gives your total estrogen and not the free hormone levels, and does not show how well your body is detoxifying estrogen.

A blood test can also measure LH and FSH which are the messages from the brain to the testes telling your body to make more hormones, this can help to work out why your hormone levels are low.

Saliva testing

Saliva testing is easy and convenient and does not require a visit to the doctor, it also measures the 3 different types of estrogen. Saliva testing only shows your levels of estrogen and also misses out on showing you how your body is detoxifying estrogen, problems with detoxification are one of the main causes of high estrogen levels.

Urine testing

Urine testing is also easy and convenient as it does not require a visit to the doctor, and can easily be done at home with a DUTCH hormone test kit.

This is my favorite way to test estrogen levels, not only because it is so convenient to do but because it measures the 3 different types of estrogen AND how your body is detoxifying estrogen, as well as progesterone and testosterone levels.

The DUTCH hormone test also measures your levels of 5a-DHT which is the more androgenic form of testosterone, like all hormones you don’t want too little of this and excess levels, especially combined with high estrogen in men can lead to hair loss, prostate problems and increased cancer risk.

There are three ways that the liver can detoxify estrogen, there is the 2-OH Estrogen pathway which is the healthy way to detoxify estrogen, but there is also the 4-OH and 16-OH Estrogen pathways that are associated with an increased risk estrogen dominant cancers, even in men as this can be a contributing factor to prostate cancer.

The DUTCH test also measures how your body is methylating estrogen, this is important for phase 2 of liver detoxification. There is a lot of research into methylation and people who have genetic SNPs in the MTHFR or COMT genes can have problems with the methylation of estrogen. B12 and B6 are both important for methylation and these markers are now measured with the DUTCH hormone test.

Finally, the DUTCH test is also the best way to assess adrenal function, high cortisol is another cause of high estrogen so assessing adrenal function is another great way to find out the underlying cause of high estrogen and low testosterone.

Other Tests

Other tests to consider are insulin and HbA1C for blood sugar control, also assess for nutritional deficiencies like Vitamin D, iron studies, zinc, and copper.

Treatments to Lower High Estrogen in Men

Once you have done the testing to give you a full assessment of your hormone health, and you understand the different causes of high estrogen in men, then you will have a better idea of the best treatment plan for you. Because everyone’s hormone tests will be different and the underlying cause is going to be different there is no one size fits all treatment plan, but there are some general principles that everyone needs to follow.

Lifestyle Changes to Lower Estrogen

Reduce Body Fat

If you are overweight, even by a few kilograms this can lead to increased estrogen levels, and the more weight that you have the more you have to focus on reducing body fat. Reducing carbohydrates, intermittent fasting, increasing vegetables can all have a positive effect on reducing weight, with my clients at Planet Naturopath I combine a specific intermittent fasting protocol with improving estrogen detoxification through the liver to lower body fat and estrogen levels quickly.

Consume Cruciferous Vegetables

Cruciferous vegetables can help to promote estrogen detoxification through the liver, this includes cabbages, Brussel sprouts, broccoli, and broccoli sprouts. They can be added to the diet in the form of smoothies, soups, and any meal.

Weight Training and High-Intensity Exercise

Weight training and high-intensity exercise will also help to lower body fat and increase your testosterone production. You don’t need long training sessions and the sweet spot seems to be 20-40 minutes most days of the week depending on your other activity levels.


Even 20-40 minutes of higher intensity exercise is not going to help if you're sitting at a desk all day, you need to also move around regularly during the day and make sure you get close to 10,000 steps a day. This does not have to be all at once and simple changes to your routine like walking meetings, standing desks, and moving around when you're on the phone can help to increase your activity levels and help to lower estrogen levels.

Healthy Digestion 

Healthy digestion is important for healthy hormone levels, this is especially true if you have constipation or other IBS type symptoms like bloating, excess gas, or reflux. The GI-MAP test is a stool test to help to identify the underlying cause of your digestion problems, it also tests for beta-glucuronidase and high levels of this enzyme can cause high estrogen in men as your body reabsorbs the estrogen back into circulation rather than eliminating it through your digestive tract.

Reduce Environmental Toxins 

This includes the types of skincare products, shampoos, and soaps that you use on your skin, your skin can absorb environmental chemicals very easily. Eliminate plastics as much as you can and do not reuse plastic bottles or heat food in plastic containers.

Reduce Stress

This is easier said than done but some simple things to start with are meditation and breathing exercises, one my favorite ways to reduce stress and optimize performance that combines both of these is the Wim Hof Method, the Wim Hof Fundamentals course is a step by step guide to improve your breathing, mindfulness and overall health.

Reduce EMFs

EMFs can affect our testosterone levels and has been associated with higher estrogen, a great way to lower your exposure to EMF's is with the Faraday Boxer shorts.

Supplements to Lower High Estrogen in Men

There are a number of different supplements that can help you to reduce your high estrogen levels, but remember that supplements are not a “magic fix” and that you will have to make the diet and lifestyle changes too, otherwise you will not get optimal results.

Also, you don’t need to take all of these supplements, what you need will depend on the results of the DUTCH hormone test as that is going to help identify the cause of your high estrogen levels, and the specific supplements that you will need.

Diindolylmethane or DIM for short is the best supplement to help promote estrogen elimination through phase one of liver detoxification. This is a concentrated version of the active ingredient from broccoli.
