Is it true men also have estrogen?

From what I heard from Dr. Oz on tv that if a man has a belly then he's producing more estrogen than testosterone then in fact will cause him to be more moody? then why would a man want a belly?

Although certain adrenal conditions can lead to obesity, much more often men get a big belly from eating fatty foods and a lack of exercise. Rarely is it because they are producing more estrogen than testosterone. The adrenal glands which sit on top of the kidneys will produce both testosterone and estrogen in men and women. It takes an adrenal tumor or one of several other diseases to cause an imbalance of cortisol and/or hormones produced by the adrenal glands, such as excess estrogen. Cushing's syndrome which usually leads to obesity is one condition that an adrenal disorder can cause. Usually some symptom other than a big belly may become apparent first. As for being moody the cause is just as likely to be emotional rather than physical.

First of all, I'd seriously question listening to someone named Dr. Oz!!
The others were right, and I know from personal experience that a belly is from the wrong diet and not enough exercise. Personally, I'm on the beer diet! :P
Some people are just moody, I know a couple of guys that are all over the scale. I just tell them to quit being sutch a be-otch and get on with it.

of course we have estrogen, just as women have testosterone.

Lots of things can cause a guy to be moody. And too much beer or too many calories can cause a belly, not just hormones.

^ He's right. :P
