Which Hormone Is Responsible For Gynecomastia In Males?

Physical health is directly related to anyone’s appearance. Our blood composition, energy, immunity levels, and quantity of minerals and salts all affect our looks. In addition, hormones are a significant component of our body structure that influences our facades. Deficiency or imbalance in any of these factors may lead to various problems concerning our outlook. Gynecomastia in males is a condition of having enlarged breast tissues. It not only deteriorates health quality but also makes men feel embarrassed. One of its reasons is a hormonal imbalance in males. Let’s explore about hormones and how they can be responsible for gynecomastia.

Hormones and Gynecomastia

Although hormones are like little messengers to your body that inform you what to do, their correct proportion is significantly vital for your physique. They equally influence the appearance of males and females but in different ways. Moreover, different genders need the same hormone in various proportions. Talking about breast size or gynecomastia, testosterone and estrogen are two crucial hormones in men.

Testosterone is just like the boss of manly stuff—it facilitates guys to develop muscle mass, get deeper voices, and grow facial and body hair. Besides, estrogen has feminine functions—it helps women grow breasts and regulates their menstrual cycle. If estrogen exceeds in quantity for any reason, it can lead to the development of large breast tissue in males. In other words, we can say that the existence of estrogen and testosterone interferes with the growth of breast tissues. So, gynecomastia in males can manifest when the hormones are not in the right balance.  

Estrogen: The Culprit Hormone

Estrogen, commonly related to females, plays a crucial role in gynecomastia. Small amounts of estrogen are present in men. Thus, an imbalance between testosterone and estrogen levels can cause extra development of breast tissues. Estrogen can come from numerous assets, including:


Puberty is a time when your body goes through several modifications, and sometimes, it can lead to brief gynecomastia in boys. Generally, during puberty, men’s bodies start making extra testosterone, the hormone that makes them taller, get muscle groups, and produce manly trends. But occasionally, testosterone levels can drop a bit temporarily, while estrogen levels stay the same or cross up a bit. Since estrogen is the hormone associated with girls and helps them to broaden female tendencies, while there is a little excessive amount of estrogen or insufficient testosterone at some point of puberty, some men may revel in gynecomastia.


Men’s bodies naturally produce less testosterone as they age. So, it might be the cause of the rise in estrogen. Furthermore, gynecomastia in males may also be caused by this hormonal shift. The hormone that gives men a masculine appearance and behaviour is testosterone, but as men age, their testosterone levels decrease. Simultaneously, the amount of estrogen, a hormone commonly seen in women, may remain constant or may even increase. Hence, older men might also develop gynecomastia since they produce comparatively more estrogen and substantially less testosterone.


Because adipose tissue contains more of the enzyme aromatase, which turns androgens into estrogens, obesity raises estrogen levels, which in turn causes gynecomastia. Men’s breast tissue grows more rapidly when their estrogen levels are high, upsetting the hormonal equilibrium. Further complicating this mismatch is the fact that obesity can diminish androgen levels because of related disorders, including insulin resistance and metabolic syndrome. Gynecomastia is induced by the combined action of elevated estrogen and reduced androgens. Restoring hormonal balance and lessening gynecomastia symptoms can be achieved by addressing obesity through weight loss and lifestyle modifications.


Some tablets, like certain antidepressants, anti-anxiety pills, and medications for prostate problems, can mess with hormone levels. However, medicines are to assist us in feeling better. But some of them can have side effects. These precise medicinal drugs can mess with the balance of hormones inside the body. Hormones are like little switches that control things like growth and mood. So when those medications interfere with hormones, it can result in gynecomastia in guys. Therefore, if a person notices this when taking such drugs, they should speak to their medical doctor. Understanding how medications affect hormones can help people make knowledgeable decisions about their health.

Other Hormonal Factors For Gynecomastia

Apart from estrogen, several other hormones can influence gynecomastia:


Testosterone is just like the primary guy hormone, making men’s appearance and experience masculine. But if there is no longer sufficient testosterone relative to estrogen, gynecomastia can take place. There are a few reasons why testosterone levels may drop: growing older is one, certain fitness situations are another, and the use of anabolic steroids can also mess with testosterone ranges. Anabolic steroids are drugs that a few human beings use for muscles, but they could throw off the stability of testosterone and estrogen. So, while there is not sufficient testosterone in comparison to estrogen, guys may likely observe their breasts getting larger. Thus, it is essential for men experiencing this to talk to their medical doctor to discern the reason and find the best remedy.


High levels of prolactin, a hormone that allows making milk, can cause gynecomastia. Prolactin usually enables women to create milk when they have a baby. However, men have it in smaller quantities. When there is an excessive amount of prolactin inside the body, it can cause gynecomastia. It may occur due to the use of certain pills, troubles with the pituitary gland in the brain, or perhaps when a person’s stressed out. So, in all these conditions, there may be too much prolactin, and men may feel their breasts getting larger.

Human Chorionic Gonadotropin (HCG)

It can spur males to make extra estrogen in a few instances. This hormone is present in guys who suffer from testicular tumors. These tumors can produce HCG, which then turns on the body to make estrogen. When there is an excessive amount of estrogen in men, it may cause trouble, in which breast tissue grows more than usual. So, if a person has excessive levels of HCG due to a testicular tumor, it can cause imbalanced hormone levels and potential gynecomastia. Hence, this hormone prominently relates to gynecomastia.

Wrapping Up

To sum up,  physical appearance is a reflection of inner health and the composition of the body. Hormones are essential parts of our body that perform various significant functions. Gynecomastia in males is a common condition that could make them feel both physically and emotionally uncomfortable. Knowing how hormones, particularly estrogen, play a pivotal role in inflicting it is crucial for finding exceptional methods to deal with it.Therefore, if you have symptoms of gynecomastia, it’s vital to see a doctor for the proper recommendation and gynecomastia surgery cure. It can be handled with the correct assistance, which could help you gain confidence and feel better. So, don’t hesitate to reach out to a healthcare expert in case you’re coping with gynecomastia. Thus, it is a step closer to feeling more comfortable and happy with your body.
