Husband's Aunt(Chachi) Claims Husband was diagnosed with Klinefelter's as a Teen.

[h=3]What Is It?[/h] Klinefelter syndrome can cause problems with learning and sexual development in guys. It's a genetic condition (meaning a person is born with it).

Klinefelter syndrome only affects males. It happens because of a difference deep inside the body's cells, in microscopic centers called chromosomes. Chromosomes are tiny, but they play a huge role in who we are — including deciding our gender, how we look, and how we grow.
Doctors sometimes call Klinefelter syndrome "XXY." Instead of one X and one Y chromosome like most guys have, guys with Klinefelter are born with an extra "X" chromosome in most or all of their cells.
When puberty starts and guys' bodies begin to make sex hormones, boys with Klinefelter usually don't produce as much of the male hormone testosterone. That doesn't make a guy less male, but it can affect things like penis and testicle growth. Boys with Klinefelter syndrome may also have problems with attention, speech development, and learning word skills like spelling, reading, or writing.
Doctors think Klinefelter syndrome is fairly common. Most boys who have it go on to have a good and healthy life, especially if they get the help they need from doctors, speech therapists, and other experts.
[h=3]What Causes It?[/h] Klinefelter syndrome isn't passed down through families like some genetic diseases. Instead, it happens randomly from an error in cell division when a parent's reproductive cells are being formed. If one of these cells is part of a successful pregnancy, a baby boy will have the XXY condition.
The XXY condition can affect some or all of the body's cells. If only some cells have the extra X chromosome, it's called mosaic Klinefelter syndrome. Guys with this condition often have milder signs and symptoms. Some may not even know they have Klinefelter syndrome until later in life. Other boys have more than two X chromosomes. Their condition may be more severe.


[h=3]Treatment[/h] There's no way to change the XXY condition if someone is born with it, but there are treatments that can help. Beginning treatment early makes it more effective.

• Testosterone replacement therapy (TRT) works by increasing a guy's testosterone levels until they are within the normal range. This can help someone with Klinefelter syndrome develop bigger muscles, a deeper voice, growth of the penis, and facial and body hair. It also can help improve bone density and reduce any breast growth. However, testosterone therapy cannot increase testicle size or reverse infertility.
• Physical therapy, occupational therapy, and speech therapy can build muscle strength and coordination as well as help guys improve their speaking, reading, and writing skills.

It's not easy to feel like you are developing differently from other guys. Guys with Klinefelter syndrome are more likely to have low self-confidence or shyness, which can make things harder. Counselors and therapists can give guys practical skills to help them feel more confident in social settings.
If you're struggling to keep up or do well in school, talk to your school counselor or teachers. Tell them about your condition. You might be able to get extra assistance and support to make schoolwork and classes go more smoothly.
