Ineligible: Hi Aiden, this amount of growth is certainly unusual, and I think a urologist would consider it something that needs monitoring. There was another member of this board, several incarnations ago, who was put on a drug that is usually used for men with enlarged prostates, that stops the conversion of testosterone into dihydrotestosterone, the hormone that causes penis growth in puberty (and prostate growth throughout life). You may have an unusually high level of that hormone.

There is a growth-stopping mechanism, that isn't well understood, that kicks in to stop the pubertal growth spurt. It could happen soon, but it's very hard to predict.
