We are in the PNW. Maybe it's because you can get away with wearing 4 shirts up here year around and no one notices?
? That's how our son fooled us.
When our son was about 16 (he's now 20) we took him to a great general practioner who was kind, and helped our son through all the blood tests. He had low levels of testosterone and high levels of estrogen. Officially it is called delay of secondary sex characteristics. After a year of testosterone patches and injections he grew from 5'10" to 6'4.5' and weight dropped from 235 to 195. His muscle became defined and his voice dropped.
However, the gyne did not go away. We asked him over and over about it, but he just would not acknowledge it. Recently I brought it up, and told him he could have plastic surgery to correct this. We went back to the same GP who is willing to write any letters necessary and retested for testosterone/estrogene levels.
I don't know where you are in the Seattle area, but if you PM I will give you as much information as I can. My son is having surgery this summer. Also, everyone on this board has been kind. You can count on them for advice and support. Good luck.
