Klinefelter Syndrome


Klinefelter syndrome has been defined as a genetic condition that results when a boy is born with an extra copy of the X chromosome. Klinefelter syndrome is a common genetic situation affecting males, and it is sometimes not diagnosed until adulthood. It may stand against the testicular, resulting in less than normal testicles, that may result to lower production of testosterone reduced, it can also cause reduced muscle mass, reduced body and facial hair, and enlarged breast tissue. The impacts of Klinefelter syndrome different and not everyone has the same signs and symptoms.

Some men with Klinefelter syndrome produce less or no sperm but helped reproductive procedures can make it possible for most men with Klinefelter syndrome to father children. The Signs and symptoms of Klinefelter syndrome may include: Weak muscles, Slow motor development that’s taking longer than average to sit up, crawl and walk, Delay in speaking, Quiet, docile personality and Problems at birth, such as testicles that haven’t descended into the scrotum.

And this syndrome does occur in men inform of: Low sperm count or no sperm, Small testicles and penis, Low sex drive, Taller than average height, Weak bones, Decreased facial and body hair, Less muscular than normal, Enlarged breast tissue and Increased belly fat.

Klinefelter usually occurs as a result of a random error that causes a male to be born with an extra sex chromosome. It isn’t an inherited condition. Human beings have 46 chromosomes, including 2 sex chromosomes which determines a person’s sex. Females have 2 X sex chromosomes that are XX. Men have an X and a Y sex chromosome that’s XY. Klinefelter syndrome may be caused by the following:

  • An extra copy of the X chromosome in each cell (XXY), is the most common cause.
  • One extra X chromosome in some of the cells (mosaic Klinefelter syndrome), with fewer symptoms.
  • More than one extra copy of the X chromosome that is rare and results in a severe form.
  • Additional copies of genes on the X chromosome may interfere with male sexual development and fertility.

A number of complications caused by Klinefelter syndrome are related to low testosterone that’s hypogonadism. Testosterone replacement therapy usually reduces the risk of certain health impediments, most especially when therapy is started at the beginning of puberty. For those with Klinefelter syndrome, It’s never too late to get treatment, but it is good to start treating it as earlier as possible.
