Klinefelter: is the disturbance that affects the genitals and the fertility of the men


Klinefelter syndrome, or XXY syndrome, is one of the most common genetic diseases among men: it occurs in 1 in 576, according to a study done in Denmark in the early 1990's by the Aarhus Psychiatric Hospital.

Humans have 23 pairs of chromosomes and the latter determines our sex. In the case of women, it is composed of two identical chromosomes (XX) and, in the case of men, two different chromosomes (XY).

The genitals and fertility of men are genetically affected by the Klinefelter disorder.

Men with this syndrome have at least one extra X, which in most cases leads to karyotype 47, XXY or, in rare cases, karyotypes such as 48, XXXY or 49, XXXXY. Thus, Klinefelter syndrome is also called XXY syndrome.

Klinefelter syndrome is also called XXY syndrome.

One of the main consequences is the deficiency in the production of testosterone, the male sex hormone. The men's body does not generate it naturally, so many inject every month since they detect the syndrome.

In many men with Klinefelter, although not at all, the genitals do not develop completely and become smaller, which hinders the production of testosterone.

One of the main consequences is the deficiency in the production of testosterone.

As a result, the breasts can grow more than normal and puberty can delay or even not occur.

Given the low production of hormones, fertility is affected. If the syndrome is detected early, sterility can also be discontinued.


In addition, they have a greater risk of developing type 2 diabetes, blood clots, involuntary tremors, breast cancer, osteoporosis, rheumatoid arthritis and lupus, according to the National Library of Medicine.

"The problem is that a lot of people are not diagnosed," he says. It is a condition so little known that even some of those who suffer it, do not understand any of this."Says Diego Yeste, head of the pediatric endocrinology unit at Vall d'Hebron Hospital in Barcelona.

Nowadays, Klinefelter syndrome in Spain is diagnosed more and more thanks to the amniocentesis, an examination realized during the pregnancy.

Can be detected.

A sample of the amniotic fluid is drawn, which is analyzed for genetic changes like this. Faced with a serious anomaly in the fetus, the mother can request an abortion during the first 22 weeks.
