I am in 15 my testicles size is 5Cmx2.5Cmx2.5Cm as length X width X height..is that size denies that i have klinefelter syndrome?

Why do you ask?: Klinefelter is a spectrum, but that's actually a pretty big pair -- you're bigger than most of your male buddies. I have trouble believing these measurements unless you actually have Fragile X! If you're getting erections and ejaculations like the other guys, XXY is unlikely and your physician can check to see if you're producing sperms if you can give him a reason. Enjoy becoming a man. ...Read more

Not everyone w/Klinefelter syndrome (extra X chromosome) develops all signs & symptoms.

So while T may be normal, most likely, it's low normal. ...Read more

It's your call: I've known guys with klinefelter / XXY diagnosed at your age or later. If you have it, or if you have real hypogonadism from some other cause, to accept testosterone replacement for athletics & bone health, but be sure you know you do have a choice. You'll get full male body and sexual development like other guys, including the joys and discomforts of being an adult; most xxy's can't be dads. ...Read more
