Hormones have a key role in how our bodies work. While many people think of oestrogen (estrogen) as a “female” hormone, men also need it in small amounts. However, when oestrogen levels become too high in men, it can lead to unwanted symptoms and health problems.
Let’s explore what oestrogen is, what levels are normal for men, signs of high oestrogen and how to bring it back to a healthy balance.
What is oestrogen?
Oestrogen is a hormone mostly linked to female development and reproduction. In men, oestrogen helps with things like bone health, brain function and sperm production.
There are different types of oestrogen, but the main one in men is called estradiol. This is made when the body converts testosterone into oestrogen using an enzyme called aromatase.
What is a normal oestrogen level for men?
Oestrogen levels can be measured through a blood test. The typical range for estradiol in men is around 10 to 40 picograms per millilitre (pg/mL), though this can slightly vary depending on the lab and measurement system used.
If levels go above this range, it may cause symptoms. The balance between oestrogen and testosterone is important. When oestrogen levels are high and testosterone is low, symptoms tend to be more noticeable and may affect both physical and emotional health more significantly.
Symptoms of high oestrogen in men
When oestrogen levels are too high, men might experience several changes in their bodies and mood. Common symptoms include:
Weight gain increases estrogen levels because the aromatase enzyme that helps in the production of this hormone is found in the fatty tissues.
An increased level of estrogen accompanied by a low level of testosterone is associated with erectile dysfunction, like weaker and less frequent erections.
Estrogen affects the psycho-sexual development of males, which takes on during early brain development. Since the aromatase enzyme is also present in the brain, estrogen formed there influences sexual behaviour from a psychological viewpoint.
Infertility is an extreme symptom of high estrogen. This hormone plays a role in the development of germ cells lining the testes. Abnormal estrogen levels can adversely affect the growth of sperm and its nourishment, resulting in infertility.
Enlargement of breast gland tissues in men.
High estrogen levels affect moods and may lead to depression, anxiety, irritability and mood swings.
High estrogen levels in men often cause fatigue or lack of energy.
Studies show that high estrogen levels cause muscle loss.
In some cases, long-term hormone imbalance may contribute to more serious health risks, which is why considering critical illness insurance should be an important part of your financial protection.
How to lower oestrogen levels in men?
Here are some ways that may help lower oestrogen levels naturally:
Fat cells can turn testosterone into oestrogen using the aromatase enzyme. Being overweight or obese often increases the risk of higher oestrogen levels.
Certain foods can help manage high oestrogen levels in men by supporting hormone balance. Cruciferous vegetables like broccoli, cauliflower and cabbage may aid in breaking down excess oestrogen, while fibre-rich foods such as oats, whole grains, fruits and beans help the body eliminate it.
Alcohol can increase the activity of aromatase, leading to more oestrogen. Drinking less or avoiding alcohol completely can help with hormone health.
Staying active helps control body fat, improves testosterone levels and supports overall health.
In some cases, doctors suggest medication or treatment to help block or lower oestrogen, especially if lifestyle changes aren’t enough. Hormone tests and treatments can sometimes be costly, especially if more regular monitoring is needed. This is where having health insurance plans in place can be helpful.
Conclusion
Oestrogen plays an important role in men’s health, but too much can cause problems, from low sex drive to breast growth. If you notice unusual changes in your body or mood, it could be worth checking your hormone levels.
