Hello,
It's been a long time since I last posted a message.
You should know that there are as many cases of Klinefelter as there are people. Every expression of the syndrome is different, every physique is different. For me, until my testicular surgery to try to find sperm (in vain), I had no symptoms apart from the long legs and I didn't even know I had this syndrome. I am not overweight (BMI 20), etc...
Before my operation I was treated with HCG for 7 months to improve my chances. After 4 months and therefore for 3 months, I discovered these strong pains that many people report. Fortunately I don't run, otherwise it would have been impossible. When I went out for winter sports, I was so irritated that I had to put cotton wool on my nipples. It only lasted 3 months but on reflection it would have been easier to buy a sports bra. After the treatment was stopped, the glandular mass disappeared and everything went back to normal.
On the other hand, during this operation they did everything they could to try to find spermatozoa, a little too much in fact, and on top of that they gave me a nosocomial infection in my testicles. That's all been sorted out but now I'm at 50% below my starting rate of testosterone (I'm still hoping it will go up a bit). I still don't need any treatment but the consequence is that my T/E2 ratio is a bit low at about 10. In the last few days I have had some irritation all over (including on the sides) in my chest but at a very very low level compared to before. It feels more like a skin irritation. Fortunately it has stopped since yesterday but I feel like I am borderline.
In any case, if it were to go to the wrong side, I would not have an operation as long as it is not too big (no more than A or B cup in Europe norms). With the operation I've had, I'm not too confident about the rest. It's really not a question of money because the health insurance in my country is known to be generous and even without it, from my point of view, health is priceless. It's really an analysis between the consequences of the operation and the gain it brings.
But fortunately, I'm not concerned at all at the moment.
