The condition exists in roughly 1 out of every 1,000 males. One in every 500 males has an extra X chromosome but does not have the syndrome. Diagnosis In some cases there are no obvious symptoms of Klinefelter’s and as such is never diagnosed. Often cases are only diagnosed when a man undergoes investigation for fertility problems. If the condition is suspected, blood tests can identify the additional Chromosome/s. Treatment Klinefelter’s cannot be cured but the symptoms can be improved.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
