It’s important to understand that gynecomastia is caused by an imbalance in Oestrogens to Androgens. There may be many causes for this, the most common one being temporary changes that occur to our endocrine system during puberty. If the changes were temporary causing some breast growth, then more often than not the breast growth recedes in a year or so. However sometimes the growth does not recede although the hormones have returned to balance.
It’s also important to remember that sometimes there are other causes. They are many and varied, but they all come down to this imbalance in Androgens to Oestrogens. Now the way I see it is this. What is the point of going into surgery if you are not sure that the breasts will grow again? All that worry, expense and recuperation would have to be repeated. If there is an underlying problem .. get it sorted first. An Endocrinologist is the expert on your hormones. A quick check by him or her will be able to tell you if your hormones are ok and that your Gyne was a ‘one off’ thing. If all is well then you can consider surgery having confidence that it will not re-grow. What price peace of mind?
In answer to your first question, I think everyone with gyne should see an Endocrinologist for the reasons I have given above.
As far as the examination is concerned I can only say what happened to me, but remember these people are there to help you. They have seen more naked bodies than you can shake a stick at. They don’t care what size or colour your genitals are; basically you have a problem and they are trying to solve it. Let them help you.
A full medical history is taken, questions about general health, when the gyne appeared, any drugs taken etc. Tell the Endo the truth, they aren’t there to judge or chastise, they are there to help. There will be a general physical examination listening to your heart, lungs, blood pressure etc. There will almost certainly be an examination of your gyne and your testicles. Don’t panic. They are trying to find out if there are any lumps or abnormalities in your testes. They won’t be embarrassed because they have seen more parts of the human body than you or I can imagine. In fact I was surprised at how relaxed I felt. I was there with a problem and these people were going to help me fix it.
Good luck and don’t worry.
