How do you reduce estrogen levels in man?

It's proven that eating too much chocolate can increase estrogen level. So, if a man's estrogen level is high... he must not eat too much choco (although thats pretty hard since chocolates tastes so good) LOL!

Another answer:

Actually, chocolate may compete with estrogen. That is why women on their monthly's prefer chocolate. It helps modulate the effects of the estrogen to help balance the mood.

If a man's estrogen level is too high, it is important to ascertain the cause. If this is a teenage boy, this is normal and usually resolves on its own. Perhaps the testes may produce some estrogen before they start producing testosterone. Or it could be that the DNA code for the testosterone receptors are not fully "unpacked" and the testosterone gets converted to estrogen until the body becomes capable of using it. This may be compounded if the male in question is overweight, since testosterone breaks down into estrogen in the presence of the aromatase enzyme, and this enzyme is most abundant in fatty tissue.

Other things that raise estrogen levels in males may include:

• Tumors
• Medication side-effects
• Mistakenly prescribed medications (like Premarin for Prednisone)
• Drug/alcohol use (allegedly, though not completely proven)
• Testosterone and steroid abuse (the body converts those to estrogen to eliminate them)
• prostate cancer therapy
• Undiagnosed intersex disorder
• Kleinfelter's syndrome
• Drugging, criminal mischief (eg., girlfriend putting estrogen in the food)
• Food tainted with estrogen (was once a meat and dairy problem)
• Misuse of estrogen cream (eg., using it as sexual lubricant and he gets it too).
• Liver disease - the body may not make the precursors for testosterone, aromatization may increase, and estrogen clearance from the body may decrease.

If you know the cause, you would stop it. Quit any unprescribed drugs. Be certain that sexual lubricants are just that, and not prescription estrogen cream. Ask your girlfriend or spouse if she uses estrogen cream and when she applies it - she may have to change her usage schedule so it isn't within a couple hours of sex. Examine any patches you wear for nicotine or medications to make sure someone didn't swap them with estrogen patches. Ask a pharmacist if you notice any unfamiliar medications in your prescriptions in case there are medication mixups. Be suspicious if the pills are football (oval) shaped and burghundy in color (possibly Premarin, CES, or Cenestin), or if the tablets are small, round, and lavender or pale green (possibly Estrace or generic). If you are on prescription medications for hair loss or given HRT for acne, then quit them and tell your doctor. If you are receiving cancer treatment, tell your doctor if you have feminization symptoms, but don't quit any medications.

Verify the source and production of your meat and dairy products. A family complained of feminization symptoms (the males were growing breasts - including the dog, the 5-year-old was menstruating, the mother stopped menstruating). It turned out they were getting chicken necks out of a farm's garbage, and the necks contained estrogen pellets (for fattening purposes).

You should also report any suspected poisoning to the police. Be suspicious if you are being coerced to take "vitamins" or there is a powdery residue in your drink.

As for other causes, only a doctor can tell you if those are relevant. If you are receiving treatment for prostate cancer or you were born with Kleinfelter's Syndrome, chances are, you would already know. A doctor can rule out cancer, tumors, advanced liver disease, and intersex disorders that were not previously diagnosed.
