Hello all,
First, I don't have a gynecomastia yet (or really an old one remains very very light from my teenage years). So you will ask why I am here. As I have Klinefelter Syndrome, I am following a treatment in order to try to improve spermatogenesis. And this treatment is based on hcg + FSH for 6/7 months. So this treatment and KS are high risks to have gynecomastia. That's why I documented myself a lot on all hormones, "normal" levels and consequences. I read a lot of scientific studies but I am not a doctor.
Normally, testosterone and estradiol should not be too low or too high. But there is also a ratio to keep. The testosterone/estradiol ratio should ideally be between 10 and 30. But if the estradiol level is too high, a correct ratio will not prevent gynaecomastia.
Secondly, aromatase (which converts testosterone into estradiol) becomes more important with age, overweight and genetic problems. For example, for a young man, not overweight and without genetic problems, the "normal" estradiol level for a testosterone level of 1000 (which is very high) should be around 30 or 40 pg/mL.
The strange thing about Traveler is that the testosterone level is so high for a 61 years-old man.
For Dudewithboobs there is clearly a problem. 167 pg/mL is enormous. Gynecomastia clearly comes from there. The T/E ratio is at 2.1 when it should be above 10.
For my part, I am 36 years old, tall and quite thin. I should even put on some weight... Before the treatment I was at 480 for testosterone and 11 pg/mL for estradiol. This is not normal for my age but it is due to the syndrome and my low fat level. It is mainly in fat that the T -> E conversion takes place.
With the treatment (4 injections per week) I have a tesotesterone of 1030 and estradiol of 68 pg/mL. My ratio is therefore 15.1. Just what I need. On the other hand my estradiol is a little high. Maybe that's why I have some feeling in my chest. But the good news is that in a month and a half of treatment, I have the impression that nothing has changed so I hope it will stay like that until the end of the treatment (in 5 months and a half). After that I will have a testicular surgery (in order to find sperm) so my testosterone level will be even lower than my initial level. But we'll see later. One thing at a time.
