Klinefelter’s Syndrome

Klinefelter’s syndrome is a genetic condition in which a human being has an extra X chromosome, and those affected will have at least two X chromosomes and at least one Y chromosome. So people with the condition are often said to be “XXY males”.

As this condition is a genetic disorder it affects the hormone levels in a man’s body, thereby reducing growth in muscles and reducing hair and body growth. Conversely there is an increase in the growth of breast tissue. In some cases, children can face learning difficulties and social problems in their childhood and during adolescence.

Symptoms of Klinefelter’s Syndrome:

The symptoms of Klinefelter’s syndrome vary from person to person and also vary at different stages of physical development. The symptoms noted at various stages are:

Symptoms In Babies:

Babies who are born with the condition of Klinefelter’s syndrome do not show any noticeable signs of the condition in their early days. But as they grow, the weakness of muscle development can be noticed. These babies may take longer than usual to achieve progress like sitting unaided and crawling. They might take a longer time to walk when compared to the other babies.

Symptoms In Boys And Teenagers:

As the male with this syndrome grows older, the symptoms can be more easily recognized. These boys may be taller and have longer legs than other boys. As they attain puberty they may notice less muscular development and also less facial and body hair growth in comparison with other teenage boys. They may also have smaller testes compared to other boys. In some cases, there can be enlarged breast tissue, weaker bones and low energy levels. All this happens due to the low testosterone levels in the body.

Symptoms In Adult Males:

Male adults with the condition of Klinefelter’s syndrome look just like any other male apart from perhaps being slightly taller than average and having a less muscular body than many other men. Kayotype testing is the method used for testing for the condition and it will show decreased levels of testosterone. Sexual function will be normal but it is not possible for men with this condition to father a child without medical assistance.
