Diagnosis Klinefelter syndrome at an early stage of the disease is virtually impossible, since it is clinically manifested just after puberty. Of course, careful approach in some cases, help to suspect the presence of pathology, as described above characteristic physical signs are detected before beginning the process of sexual development of the boy.
It is important to know that a significant addition to the growth, which distinguishes the patient from his peers, usually observed between the ages of 5 and 8 years old. For the diagnosis of Klinefelter syndrome yet another characteristic feature can serve as gynecomastia, or breast enlargement. However, it should be noted that this symptom is observed only in half of the patients, as well as the small size and hardness of the testes.
However, if these symptoms occur, you should take a blood test to determine the level of sexual hormones. However, a complete diagnosis of Klinefelter syndrome also involves the study of a set of chromosomes, ie male karyotype. Only after such an analysis may confirm the diagnosis.
With regard to the treatment of Klinefelter's syndrome, the experts strongly advise to start it immediately after detecting the presence of the disease. However, it should say at once that it is most effective before puberty, when the body is able to respond to therapy as needed. In this case, all external signs of the disease can be eliminated.
Thus, Klinefelter syndrome treatment is carried out primarily with the use of hormone replacement therapy with testosterone. This provokes a timely expression of secondary sexual characteristics, as well as promotes social adaptation and correction of the intellectual abilities of patients.
