What is Klinefelter’s Syndrome?

Klinefelter’s Syndrome is a genetic disease encountered in men. Influencing men’s development, this condition is usually not noticed until adulthood. A healthy person has 46 chromosomes consisting of 23 pairs. Sex chromosomes are found as XY in men, and XX in women. The men with Klinefelter’s Syndrome have more chromosomes. And this condition has no specific reason.

How is Klinefelter’s Syndrome Diagnosed?

Chromosome analysis is made in the diagnosis of gene related diseases. Klinefelter’s Syndrome is usually diagnosed by the physician when men visits the doctor with the infertility complaint. Being highly common, the disease is seen in 1 in 600 men.

Klinefelter’s Syndrome is diagnosed when the result of the chromosome analysis turns out to be 47 XXY while it is expected to be 46 XY. FSH and LH hormones are higher in the blood. The insufficient production of testosterone hormone delays the start of adolescence and lead to infertility in the future.

Can Men with Klinefelter’s Syndrome Become Fathers?

Studies done in the recent years have shown that men with Klinefelter’s Syndrome could have sperms even a little. In case sperm cannot be found by ejaculation, it could be fund by surgical methods. Sperm cells hidden in the tissues can be found by TESE operation under anesthesia to be used in IVF treatment. Sperms found are fertilized with the egg through Microinjection (ICSI) method.

The embryos do not have the risk of carrying this disease because Klinefelter’s Syndrome is a genetic disease. Depending on the development, the embryos which are ready for transfer on the 3rd or 5th day are sent to Pre-implantation Genetic Test (PGT). Through PGT test, the healthy embryos are determined and used for the transfer.

If no live sperm is found and no healthy embryos are obtained in the genetic screening, Sperm Donation (Banka Sperm) treatment can be considered.
