High estrogen levels in men can be caused by a variety of factors, including:

• Aromatase enzyme: This enzyme converts androgens into estrogen, leading to a rise in estrogen levels.
• Diet: Consuming a diet high in refined carbohydrates can increase body fat, which contains the aromatase enzyme. As a result, as body fat increases, estrogen levels can also increase.
• Stress: Under stressful situations, the human body releases cortisol hormone, which can suppress other central hormones such as testosterone. As testosterone levels decrease, estrogen levels can increase.
• Tumors: Certain tumors can produce estrogen, leading to high levels in men.
• Weight gain: As men age and their metabolic rate slows down, they are more likely to produce more estrogen as aromatase enzymes live in fatty tissues. Therefore, weight gain can contribute to high estrogen levels.

Symptoms of high estrogen levels in men can include weight gain, erectile dysfunction, low sex drive, infertility, enlargement of breast tissue, depression, loss of energy, and decrease in muscle mass. If you are concerned about your estrogen levels, it is important to speak with a doctor or specialist for help.
