Estrogen in Male

Estrogen in Male

Simply put, estrogen basically contributes to the overall function of both males and females. Typically estrogen is known as a female hormone and testosterone as male. But it is not entirely correct.

Males have high amounts of testosterone and females have higher estrogen content in their blood. Estrogen in males needs to be in balance to control sex drive, erection, and sperm production.

Diagnosing Low Estrogen

Diagnosing Low Estrogen

E2 crash symptoms are pretty similar to low testosterone symptoms. You might think you have an E2 crash but there’s a chance it’s not the reason.

The proper way to find out is to conduct a blood test to fix crashed e2. You will receive lab results in about a week. After the result, it’s your doctor who will suggest what to do next.

At different ages, the normal estrogen level in blood is different. Let’s take a look at the estrogen level at different ages. Then you can consider whether your E level is so low or not. If you take arimidex with test cycle, you may go through Arimidex crashed estrogen as well. 

Types of Estrogen

Types of Estrogen

In female bodies, it is responsible for menstruation, productive cycle, pubic hair, and puberty. Following organs produce estrogen in the human body.

  • Ovaries (In females).
  • Adrenal glands.
  • Fat tissues.

There are different types of estrogen that can be found in almost every human body.

1. Estrone

This type of estrogen is typically present in both males and females. And in female bodies, it is present specifically after menopause. It is a relatively weaker form and can be converted to other forms of estrogen when necessary.

2. Estradiol

This is the one present in both male and female bodies. And that’s the bad boy you should most worry about. Because estradiol getting low can result in low sex drive, depression, and even acne. And estradiol getting high would increase uterine and breast cancer risk.

3. Estriol

This one also concerns females more than males. Because this one rises during pregnancy to grow the uterus and prepares it for delivery. And its level shoots up right before birth.

Let us have a glance at the normal level of estrogen in the male body.

Normal Estrogen Level in Men

Men have two main types of estrogen present in their bodies, namely estrone, and estradiol. And it is measured in Picograms per millimeter.

Prepubescent Male

  • Estrone: 16 pg/ml
  • Estradiol: 13 pg/ml

Pubescent Male

  • Estrone: 60 pg/ml
  • Estradiol: 40 pg/ml

Adult Male

  • Estrone: 10-60 pg/ml
  • Estradiol: 10-40 pg/ml

Raising Estrogen Level After E2 Crash

In order to treat E2 crashes, your doctor may suggest HRT (hormone replacement therapy). HRT will help balance your estrogen level. Also, your doctor may suggest medications.

In addition, if you have messed up your TRT cycle somehow it’ll cause low estrogen too. Make sure to look for low e2 symptoms TRT cycle may have. You should immediately stop taking aromatase inhibitors in this case.

Lifestyle changes can certainly address low estrogen levels. Foods, exercise, water intake, and mental calmness can give you better results too.

  • How long does it take to recover from crashed E2?

Honestly, the period of e2 recovery is unpredictable. Most people may recover within a few weeks. However, for some people, it might take longer than that. You need to stop taking AI. Instead, take more T and have patience. 

  • Does low estrogen cause weight gain in males and females?

In women yes, in men not so much. Estrogen is present both in men and women but it’s particularly a women ‘s hormone. In women, the estrogen hormone estradiol regulates weight gain. Lower levels of estradiol may cause weight gain. Women may experience this gain around their hips and thighs. 

  • What will Estrogen do to a man? 

Estrogen is produced in male bodies. An increased amount of estrogen can cause the breast tissues to grow, and reduce libido, erection, and ejaculation. Too much estrogen can also cause gyno in men which makes the breasts larger. You can take sildenafil and tadalafil to ensure erectile functions. 


Low estrogen levels are either hereditary or caused by wrongly taken anabolics. Even some people deliberately crash their E2. However, it is not a thing to take lightly. An E2 crash can seriously affect your life and activities in the long run.

Well, e2 crash symptoms are pretty similar to low testosterone. So whenever you experience any of those symptoms. First of all, stop taking your AI if you are taking any. 

Then without further ado conduct a blood test and then consult the doctor. Based on your tests the doctor will properly guide you about the next step.
Be aware, and stay safe.
