Causes of Man Boobs and how we can help

GYNECOMASTIA & MALE CHEST REDUCTION

Breast tissue exists in both men and women. Whilst in most cases, breast tissue does not develop into anything for men – when it does, it is medically known as gynecomastia, or more commonly – man boobs.

What causes Man Boobs?

More than 30% of men experience enlarging breasts at some point in their lives. Gynecomastia or Gynaecomastia can appear when an excess of glandular tissue is produced which causes the appearance of a more prominent chest and/or pointy, puffy nipples – man boobs.

When we see patients seeking male chest reduction, they often ask what has caused them to develop gynecomastia. Below are some possible reasons;

Gynecomastia is not specific to a certain age range, it can occur at any time it is most common in teenagers or those who are aged 50 or over.

When men start puberty, their chests undergo a period of development and swelling of the chest in this area is normal. For many, this will gradually decrease over time but for others, it will stay which is called idiopathic gynecomastia. Idiopathic is when there is an imbalance between testosterone and oestrogen. Typically, male testosterone levels will stop breast tissue from developing, but when there is an imbalance, can take over which results in breasts growing.

For men that are getting older, they do also become more likely to have gynaecomastia as this is when their testosterone levels start to change again which can result in excess oestrogen being which causes the breasts to grow.

Hair loss drugs such as Propecia or Finasteride are often associated with gynecomastia. Hair loss drugs essentially work to cause a decrease in the conversion of testosterone to a really powerful form of testosterone, called dihydrotestosterone, or DHT. This then reduces the levels of testosterone causing an imbalance.

Illegal testosterone medications that are often used in the body-building circuit are often a common culprit for the of gynecomastia. Known collectively as anabolic steroids, these drugs are synthetic versions of testosterone which often convert to estrogen which again, causes that imbalance which encourages male breast growth. The issue with ???performance-enhancing drugs’ is that there often is not a set guideline on how much should be taken like there is with medication so many end up taking too much which can lead to side effects such as gynecomastia.[1]

Testosterone Replacement Therapy is a great treatment for improving muscle mass, energy levels, sexual performance and mood but a side effect of this can result in temporary male breast growth.[2] Men have an enzyme within them called aromatase which converts testosterone into a form of estrogen. This means that although you can be increasing the testosterone levels this can also cause an increase in estrogen levels. In most cases, any breast growth that occurs during Testosterone Replacement Therapy is only temporary and should only cause a small increase which will recede in a few weeks. In some instances, your GP may stopping treatment for a month or two to allow the breast tissue to return to normal.

Excess fat that causes male chest prominence usually has nothing to do with the glandular tissue, and is instead diagnosed as Pseudo gynecomastia. This is when there is an excess amount of fat in the male chest area. Many patients are able to treat this with diet and exercise. Fat in this area can be and treatments like liposuction can help to remove the fat resulting in a flatter chest.

If a patient is carrying a large amount of weight, their leptin levels can be high. High leptin levels can trick your brain into thinking it is food-deprived which is known as leptin resistance. This results in signals being sent to the brain to conserve energy which results in a decrease in certain such as the luteinizing hormone (LH) and the follicle-stimulating hormone (FSH). These hormones are responsible for sperm and production. As the production of testosterone decreases, the production of estrogen increases which then causes true gynecomastia. [3]

plant oils can have ingredients within them that have estrogen-like properties. You do not have to ingest oils as just applying them to the skin can result in them being absorbed and entering the bloodstream. So even if you were not using them directly on the chest area, over time it will eventually make it to the breasts. We often ask patients in consultation if they have started using anything new in the past 3-6 months and to try stopping that to see if it has an impact on the appearance of gynecomastia.[4]

If a patient is suffering from any type of serious illness it can cause gynecomastia to develop as during these times your body does not produce as much testosterone causing that imbalance.

Liver disease in particular causes a disruption in protein synthesis which basically results in a sex hormone binding globulin (SHBG) being produced which sticks to testosterone. This means that patients with liver disease will not only have their testosterone production decreased due to being ill but the increase in SHBG will also bind the limited amount of testosterone that they do have meaning there will not be enough to do its job properly and often estrogen will start to take over.

This is of course very rare, and gynecomastia should not be classed as a symptom of liver disease and if you were to be suffering you will have noticed this far sooner than it takes for any sign of gynecomastia to appear. [5]

Some types of tumours can affect your hormone production. This often includes pituitary or testicular tumours. If your body is unable to produce enough testosterone or produce too much estrogen then this imbalance can result in gynecomastia. Other tumours such as lung tumours can start the production of a hormone called Human chorionic gonadotropin (HCG) which acts like the Luteinizing hormone (LH) and increases testosterone production but also stimulates the conversion of testosterone to estrogen. The imbalance and increase in estrogen can cause gynecomastia.

This is a very rare cause of gynecomastia and in most cases, the development of gynecomastia is a common benign condition.
