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 2010 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!
