Nooo...nooo....don't worry Gwen. There are many things that will cause males to convert testosterone into estrogen. The most serious of which would be diminished liver function. The liver "removes" a certain amount of naturally occuring estrogen from the body. If the liver function is diminished then it could result in a high estrogen level.
There are also other not so serious mechanisms that can cause the same thing. It could be an excess of aromatase enzyme which is easily controlled. The aromatase enzyme naturally converts testosterone into estrogen so if there an excess of aromatase there will be higher estrogen levels.
Obesity is another potential cause (not saying this is the case...I don't even know you

). Fat cells produce aromatase enzymes, especially abdominal fat, so the more fat the more aromatase and the more testosterone converted to estrogen.
Zinc definciencies can also create high estrogen levels. Zinc is a natural aromatase inhibitor so low zinc levels means more testosterone is being coverted to estrogen.
Alcohol consumption has proven to increase estrogen in men AND women. <considers this as she sips cocktail>
All of these are reasons to see your endocrinologist who can do a more detailed blood workup. The primary danger of high estrogen levels in a male patient who isn't on HRT is that naturally occuring mechanisms, as those listed above, will eventually lead to a low testosterone level. While this may sound appealing to transsexuals it is a very dangerous condition. When estrogen levels are high and testosterone is low you are at an increased risk of problems such as heart attack,stroke and pulmonary embolisms. Obviously the other things that can occur are low libido, breast growth and impotence. As long as your testosterone level is acceptable you are relatively safe with a high estrogen level. Still it is important that your endocrinologist find the underlying cause for the estrogen increase before the levels of estrogen/testosterone reach a potentially dangerous imbalance.
