General Sexual Health ProblemsKlinefelter syndrome – xxy syndrome, symptoms and treatment

Klinefelter syndrome is a genetic anomaly where a boy is born with XXY chromosome instead of regular XY chromosome. Typically, a male carries XY chromosomes and a woman carries XX chromosomes. When these two combine, the resultant may be an XX or an XY that defines whether the offspring is a female or a male respectively.  A person may not know about this condition until he has problem when trying to have a child. Klinefelter syndrome doesn’t have a cure but it is a treatable condition.

Klinefelter syndrome – causes

It is noted that women who get pregnant at older age tend to give birth to boys with XXY chromosomes. However, this is not the case always but getting pregnant at an older age carries a risk of the child being born with Klinefelter syndrome.

The additional X chromosome in the boy can be due to an additional X chromosome either in the egg or the sperm while the fertilization is taking place.  Different types of Klinefelter syndrome exists such as:

  1. An extra X chromosome in every cell, which is the most common form of Klinefelter syndrome.
  2. An extra X chromosome only in some cells. This condition is called “mosaic” Klinefelter. In such cases, impregnating a woman partner may not become an issue.
  3. More than one additional X chromosome. Though this is very rare but this is a severe form of Klinefelter syndrome.
