Klinefelter's Syndrome isn't rare - but it is rarely diagnosed...

The Klinefelter’s Syndrome Association (KSA) offers support and information to all affected by, or having an interest in, Klinefelter’s Syndrome (KS) and XXY.

The aims of the KSA are:

• to offer support and information to all affected by KS and XXY
• to raise awareness of KS and XXY especially amongst the medical profession
• to promote research into the management of KS and XXY

Through this website and our helpline information is available which can assist employers, teachers, social workers and the medical professions, amongst others, who come into contact with people diagnosed with KS and XXY.

If you are an adult diagnosed with Klinefelter’s Syndrome, please visit our adult area for information and advice about how Klinefelter’s Syndrome could affect you.

If you have just received a diagnosis of Klinefelter’s Syndrome for your child or unborn baby you will find help and information in our Children’s area.
