Man Boobs And The Estrogen to Testosterone Ratio

Man Boobs And The Estrogen Testosterone Ratio

Man boobs occur when your chest is exposed to a high estrogen to testosterone ratio. This is when you have high levels of the female hormone estrogen, and/or low levels of the male hormone testosterone.

Why You Can Still Get Man Boobs If You Have Normal Hormone Levels

It's important to note that you can also get man boobs when your hormone levels are normal, and your breast tissue is just more sensitive to normal levels of estrogen, or less sensitive to normal levels of testosterone.

Just like hormone levels, breast sensitivity to hormones changes in response to your environment. Many (though not all) of the same factors that cause estrogen levels to rise, also cause an increase in the sensitivity of your breast tissue to estrogen. The same applies to testosterone.

So generally when I talk about rising and falling levels of these hormones, know that I'm also referring to falling and rising breast sensitivity to these hormones.

Where you can test your hormone levels using salivary and blood tests, there is no way to test for the level of sensitivity of your breast to these hormones.

Changing breast sensitivity to hormones is an important aspect of breast development that a lot of guys don't know about. Many of my clients find their hormone levels are normal, and this just means that their breasts are more sensitive to estrogen and/or less sensitive to testosterone because of estrogen/androgen receptor abnormalities. These abnormalities can be acquired from exposure to environmental toxins, or from birth because of hormone exposure from the mother's womb.

Some people are just born with more estrogen-sensitive breasts, which is why man boobs tend to run in the family.

Whether your hormones are normal or abnormal, natural male breast reduction techniques can go a long way in helping you to reduce the size of your man boobs.


The female sex hormone estrogen is what's responsible for girls developing breasts during puberty. Some years ago, I read a newspaper article that talked about how women's breasts nowadays are bigger than they were just 20 years ago. This is happening because women are now being exposed to higher levels of estrogen than ever before.

As a guy, you probably think this is awesome, but not when you find out what these high levels of estrogen are doing to us men. Not only does high estrogen exposure cause men to grow boobs, it also affects the hypothalamus and pituitary gland in the brain, leading to decreased testosterone levels, reduced sperm count, reduced fertility and reduced libido. It also makes it difficult for us to lose weight and put on muscle. All in all, increased exposure to estrogen is making us men more feminine.

Although man boobs and our masculinity is a huge concern to you and me, there isn't much scientific literature out there to pinpoint why men are becoming feminized. But what we do know is that man boobs are caused by estrogen. Estrogen has been studied extensively because of its strong link to the third most common cancer in the world – breast cancer.

Most things that increase a woman's chance of developing breast cancer, will also increase a guy's chance of growing man boobs. Knowing this, we can now analyze the scientific literature on breast cancer, and deduce important facts about man boobs.

One thing we know is that breast cancer has been on the rise worldwide ever since the explosive growth of the chemical industry in the 1940s. We don't know this for a fact, but I wouldn't be surprised if man boobs didn't go on the rise at around the same time.

Unfortunately, whether you live in a developed or developing country, estrogen and estrogen-like particles called ‘xenoestrogens' have somehow managed to become some of the most abundant chemicals we're exposed to every day.

Thanks to the multi-billion dollar global chemical industry, estrogen is everywhere in the modern environment. Estrogen is abundant in our water supplies, and estrogen-like particles are found in the vast majority of foods available to us. Car exhaust fumes contain estrogen-like particles that we inhale through our lungs. Even the cosmetics we apply on our skin (including deodorants) contain estrogen-like particles that are easily absorbed through the skin.

In later articles (like this onethis one, and this one) I'll be giving you some of the best tips and tricks on how to lower your estrogen levels right down. So keep your eyes peeled.


Androgens are male sex hormones. Testosterone is the primary and most well-known androgen.

Testosterone is responsible for boys developing a deeper voice, increased muscle mass and increased body hair during puberty.

Testosterone does a hell of a lot more than this though. Optimal testosterone levels help fight depression, decrease body fat, increase muscle mass, delay aging, strengthen your heart, strengthen your bones, increase libido, improve erections, improve cognitive functioning, and have many other physical and psychological benefits.

Having optimal testosterone levels can have a HUGE positive impact on your life. Having low testosterone on the other hand, gives you the opposite of everything I just listed in that last paragraph. Another thing low testosterone gives you is man boobs… which really doesn't help.

Your testosterone levels are closely linked to estrogen via the hypothalamic–pituitary–gonadal axis. The hypothalamus and pituitary being portions of your brain, and the gonads being your testes. When estrogen levels go up, your testosterone levels go down.

In a 2007 study in the Journal of Clinical Endocrinology and Metabolism, the researchers concluded that over the past 20 years, there has been “substantial age-independent decreases in male serum T concentrations”.

Today, the average male has a testosterone level that is 15-50% (depending on the study you read) lower than it was 50 years ago. So there's no wonder then why rates of male fertility have plummeted in recent years.

Studies have shown that in the past 50 years, the quality of sperm has dropped by 42%, and the quantity by 50%. In the past 20 years the decrease in sperm counts has occurred at a rate of 2% each year.

Increases in estrogen and decreases in testosterone are literally transforming men into women. No wonder we're growing breasts!

The good news is I have discovered some unusual yet powerful methods you can use to both boost testosterone and kill estrogen levels in a way that can help obliterate your man boobs in a matter of weeks!

    • Hi Reneesh

      Thanks for your comment. How old are you now? Unfortunately, some people have a natural tendency to grow man boobs when they get out of shape. This can be ingrained in a person’s genes if they are exposed to high estrogen levels while in the mother’s womb before birth. Thankfully though, environmental factors play an important role as well. Since getting in shape worked for you in the past, the best thing you can do is get back in shape again. Contrary to what most people think, this really doesn’t take too much commitment if you know what you’re doing. You don’t even need to go to the gym.

      I suggest you take a look at the Chest Sculpting Blueprint. It’ll help you get that chest fat under control with minimal time commitment.

      Let me know how it goes.

  2. Yes, I am interested in knowing your thoughts on boosting testosterone levels for I have a son with a condition that causes him to have low t levels and high estrogen levels. He has the “man boobs” and is very uncomfortable about it. Please help, any advice/suggestions would help.

    • Hi Althea, thanks for the question. Sorry to hear about your son’s condition. Might I ask what this condition is? Has the doctor offered any help with medical therapy? And how old is your son? How long has he had his man boobs for, and how big are his man boobs? Does he have any tenderness behind his nipples?

      There is so much I could talk about when it comes to boosting testosterone naturally. I intend to do a detailed section on testosterone on my website in the future. One reliable source of free information is I also discuss how to boost testosterone in a way that helps get rid of man boobs, in my program, How To Lose Man Boobs Naturally.

  3. Hello, 

    I have been noticing that my left chest mass has been incresed in the past few years, I am 23 years now. I used to be in shape few months back but since i have been out of shape. I'm feeling that only the left chest is increasing like man boob. I can feel a bit of a mass under left chest. I also have puffy nipples most of the time and need to pinch it to get to normal shape. My right chest size is normal. Could you please suggest the problem and the solution.

    • Hi Dave

      Unilateral gynecomastia is more likely to be associated with an underlying disease process, so the first thing you should do is to see a doctor. This is especially important seeing as your left man boob is still growing at the age of 23.

  4. I am 53 year old male,weight 185 6ft pretty forgetful,low energy,decreasing sex drive,with mild depression.Suspect I might have excess estrogen/lower than normal testosterone[under 400] what would be a good ratio of testosterone to estrogen and can a blood test show me the correct numbers.

  5. hey! awesome and very detailed explanatuon there, im an 18 yr old dude and im having a serious issue with man boobs, i used to be really skinny but about 5 years back, i started gaining weight like crazy……mostly muscle at the time but not anymore, im 6″3 and 93 kilos.
    i have a big butt and really noticable man boobs,…….i think im a bit forgetful but nothing serious, i have a reasonably deep voice, i do get alarmingly angry sometimes, and have issues with depression and insomnia,im also quite hairy on my body and face although i havent really grown a full beard. ……….i am actually quite a bit overweight but not FAT ,cuz i have a big belly and thighs along with a very big butt

    i actually havent seen a doctor but i think its obvious that my hormones are a bit fucked up…….

    ….i need your advice cuz my physique is really killing my confidence and social standing, i intend to join a gym but……i start college in a few months so i really cant afford to pay for all those supplements along with anti-estrogens etc

    sorry for the long post but im desprate!
    thanks bro

    • Hey Ryan

      At 18, pubertal gynecomastia could be at work. First thing to do is to see your doctor to get it checked out – just to make sure you don’t have something sinister going on with those man boobs. A sinister source doesn’t seem likely in your case, but you never know for sure until you get it checked out.

      Minus any sinister causes, the next thing to do is to lose the weight but if you want the man boobs to come off too, you have to do it all a certain way. Most people who are overweight with man boobs, try to lose the weight using methods that reduce testosterone levels – such as long distance cardio, a low calorie diet, and/or a low fat diet. When you do this, because your testosterone levels go down, you end up losing weight from everywhere except your chest.

      A big butt and hips is a feminine bodyfat distribution pattern, and a lot of guys with man boobs also store fat in these areas. The best way to get rid of your man boobs and butt, is to lose the fat using methods that help keep those testosterone levels up. They include intermittent fasting, a low carb diet, high intensity interval training, and resistance training.

      Hope this helps.

  6. Hi there, so as a child I suffered from testicular torsion consequently having my testicles removed. As I reached my teenage years I was quite skinny but I realized when I was playing football I would wear DriFit shirts and I started to notice how I looked in my chest area, I then thought that I was forming man boobs as a young teen which took a shot at my confidence. I started to go for runs. I worked out but only a couple times a week but only because I was too tired from year around baseball and especially practices. I did not notice a change in my body physically, being pubic hairs armpit hair facial hair or anything I should say I was not going through puberty. My primary physician noticed that I was relatively small in my area and referred me to an Endocrinologist. It was there that I was prescribed Testosterone shots, I started off with 50 mg with and every month to month shot,I then made my way up to 200 mg every month and my Endocrinologist decided recently to knock me down 50 mg concluding me to 150 mg every 2 weeks. I told my new Endocrinologist (I was given a new one because I turned 18) I was having chest pains my mainly on the left side of my chest being my left boob. I am not quite sure what to think about this or what you think I should do about this. I am 5’10 weighing 185 and I started developing stretch marks on my hips and underneath my armpit. If you could get back to me as soon as possible that would be great. Thank You.

    • Hi Mike

      The pains you are experiencing could be from either too much or too little testosterone. Excess exogenous testosterone is converted to estrogen by the enzyme aromatase. It’s very common for bodybuilders who abuse testosterone to grow breast glands, and it’s possible that you are growing tender/painful breast glands as a result of aromatization of your testosterone. Bodybuilders often take aromatase inhibitors alongside their testosterone, to prevent the aromatization of their testosterone.

      Since you are not producing much of your own testosterone, then taking too little exogenous testosterone in your case, could also result in tender/painful breast glands.

      I would suggest seeing your endocrinologist, who might suggest a dose-change, or possibly even adding in an aromatase inhibitor.

  7. Hey I am 21 year old and suffering from same problem as they have mentioned above …I need suggestions to improve my sperm count and remove men’s boobs and as I am vegetarian guide me accordingly and please mention all the things in detail e.g(low calorie food) so explain me that what should I eat to get low calorie food.

  8. Hi! This is a brilliantly written post. Cleared most of the doubts and queries I had about low T.

    I am a 32 year old Indian Male, 5’10” height, 90 kilograms weight.

    I have been obese since my adolescence and had developed man boobs at a pretty early age. Sedentary life style and calorie rich diet contributed to it. By the time I reached the age of 21, I weighed over 120 kilograms, and remained at that weight till the age of 26. At the age of 26, I decided to take control of my life and started excercising, and was able to bring down my weight to 80 kilograms from 120 kilos. It made a drastic change in my appearance, my self -confidence but the man boobs did not go away entirely (although it was no visible anymore with clothes on).

    Now at 32, I weigh 90 kilos, work out 3 days a week, take multivitamins, protein, and Zinc Magnesium and Omega 3 supplements. I got my Test checked today. The result is 414 ng/dl (test done is through CLIA method)

    Please help me out with the following:

    1. Is 414 ng/dl low given my age, my current life-style, and my history of being obese?

    2. I still have man boobs. Will it go away if I continue to boost my TEST further and take it to say 600-700 level using exercise, diet, supplementation and rest?

    3.Would you suggest considering TRT at this stage?


  9. Sir I am 32 years old

    Is this behaviour called that I m turning to gay.
    Please help

    • Hi Zayed

      It sounds like you either have too much estrogen or too little testosterone in your body. I would suggest seeing a doctor and getting your hormone levels checked. It’s also important for your doctor to rule out any serious underlying disease, like an estrogen secreting tumor that needs to be taken out via surgery.

      The natural approach I talk about on my website can help you boost testosterone and estrogen, but it’s important to first find out if there’s an underlying cause that needs to be treated medically or surgically.

  10. My man boobs are a strange thing, they can come and go through the day and i’m yet to find the true reason why…

    I believe its due to a buildup of fluid, but the cause I don’t know, I’ve tried low sodium,higher sodium, low carbs, higher carbs, estrogen tabs, you name it but It continues to come and go.

    The one way ive learned to keep them away is holding in a pee, yes sounds stange but at the point of needing to urinate my chest looks normal… once I urinate the water builds back up in my chest area… maybe I lose something through urination…

    Eating also gets rid of the problem for a short while…

    • Hi Kevin

      These fluctuations in the pointiness of your man boobs are likely due to hormonal changes throughout the day and fluid redistribution.

      You’ll see your chest flatten up when you are exposed to cold, such as in a cold shower. This happens because cold exposure causes fluid to be distributed away from your surface and toward your core.

      The same happens after exercise, when fluid is distributed away from your surface and into your muscles.

      Eating may cause it because it results in increased blood flow to the gut, and hence cause fluid distribution away from your surface and toward your gut.

      One thing you’ll find is that as you reduce the size of your man boobs through the right diet, exercise, and lifestyle changes, they’ll still fluctuate in their pointedness throughout the day, but after you get to a certain point, it just tends to stay flat all the time.
