Diagnosis And Effects On Fertility Of Klinefelter Syndrome
Klinefelter syndrome is a common genetic disorder that only affects men. Men with this order are born with an additional X chromosome and have small testes. Klinefelter syndrome affects the production of hormone testosterone in men before birth and at the time of puberty. Due to this low level of hormone during puberty male sex organs do not develop fully, which in turn affects the testicle function and sperm production. Lack of testosterone is also responsible for infertility.
There are no specific symptoms of this disease and thus, it is often not noticed until a man starts trying to get his partner pregnant. The only symptom of this ailment is that men suffer from irreversibly infertility. There are more chances of having a child with KS in case women conceive at later stages of their lives.
What is Klinefeltor's Syndrome?
Generally, each cell of body has 46 chromosomes arranged in 23 pairs. These 23 pairs of chromosomes are autosomes, which determine physical features. Along with these autosomes, there is a pair of chromosome, which determines the sex of a child. In this pair, one chromosome is inherited from father and other from mother.
Women have two same kind of sex chromosome (XX) and men have two different types of sex chromosome (XY). Klinefeltor's syndrome is when there is an extra chromosome in males. This syndrome mainly affects boys and men who usually have 47 chromosomes instead of 46.
