Testosterone is what makes a man a man, and estrogen is what makes a woman a woman, however, estrogen is in many aspects just as important to a man’s health as testosterone. And, despite them being regarded as the polar opposites of human sexual development and behavior, on a molecular scale they are very similar.
If you try to merge both molecules into a 3D figure you would find them looking identical except that testosterone would have one extra carbon atom into its molecular structure. And it is precisely in this similarity that we find the reason why some men experience high estrogen levels. Considering that the testosterone molecule is so similar to estrogen, it is extremely easy for various aromatase enzymes to cut off the one extra carbon atom from the molecule and convert it into estrogen.
This is a good thing because as we already explained, you need a certain estrogen level. Not only does it have lots of positive effects on your health, it is also a part of an efficient feedback mechanism where overly high levels of estrogen send an alert signal to the testicles, via the pituitary gland, to reduce the production of testosterone for that particular day.
This way, the feedback mechanism keeps a perfect balance between estrogen and testosterone levels throughout the system. There are instances, however, where too much testosterone is converted into estrogen. This amount added to the small quantities of estrogen already produced in the testes, adrenal glands, brain, and fat has the potential to create a dangerous hormonal situation.
When a man allows his estrogen levels to increase, the risk of developing various degenerative diseases increases dramatically, one of the most common being atherosclerosis. The risk of getting a stroke or prostate cancer increases, as well as the risk of developing type II diabetes. One is also more inclined to experience emotional disturbances. Erectile dysfunction occurs, fat gain accelerates, it becomes harder to gain muscle and most importantly, having high estrogen levels significantly increases the risk of premature death.
The main symptoms of high estrogen:
Muscle mass loss
Increased abdominal fat
Low libido, possible erectile dysfunction
Increased fat around the nipples
Depression and emotional disturbances
Lower urinary tract symptoms usually associated with benign prostatic hypertrophy
