Having two X chromosomes and one Y chromosome (or a genotype of XXY, instead of XY) does indeed have a name ? and that name is Klinefelter syndrome! Bravo for wanting to find out more about this condition that occurs more often you might suspect. Klinefelter Syndrome ? or KS for short ? affects one out of every 500 to 1,000 baby boys of all races and ethnicities, although many people might not ...

Klinefelter syndrome is the most common sex chromosome abnormality (SCA) in infertile patients and 47,XXY genomic configuration constitutes most of the cases. However, additional Xs and/or Y such as 48,XXYY, 48,XXXY, and 47,XYY can occur less frequently than 47,XXY. Those configurations were considered as variants of Klinefelter syndrome.

The likelihood of finding spermatozoa in the ejaculate or testicular tissue of patients with mosaic Klinefelter's syndrome is low, and with the non-mosaic form, even lower. We describe a patient with non-mosaic Klinefelter in whom initia...
