When a lad is born with a duplicate copy of the X chromosome, he might have Klinefelter syndrome. Klinefelter syndrome is a genetic problem that affects males, and usually, until adulthood, it is not yet identified.
Most guys suffering from Klinefelter Syndrome make a small amount of sperm or no sperm at all. This syndrome may also be a hindrance or affect testicular growth, which can lead to little than normal testicles, that can end up producing a lower amount of testosterone.
Klinefelter Syndrome’s effects might be different from people who are experiencing it. They do not have the same symptoms and signs. The said syndrome may have an impact like a lower amount of body and facial hair, more prominent breast tissue, and a lessened mass of the muscle.
