Fertility Preservation in Klinefelter Syndrome Patients during the Transition Period.

Abstract : Spermatozoa have occasionally been identified in ejaculate of adult Klinefelter syndrome (KS) patients but very exceptionally in KS adolescents. Spermatozoa can also be retrieved in testicular tissue of KS adolescents. The testis may also harbor spermatogonia and noncompletely differentiated germ cells. Neither clinical features nor hormonal parameters could predict germ cell recovery in KS adults or adolescents. No predictive factors can actually demonstrate that early diagnosis of KS would allow increasing the chance of sperm retrieval even if it has been suggested that semen quality may decline with age in KS patients. Leydig cell dysfunction may also be another factor that might affect the spermatogenesis process in XXY adolescents. Fertility preservation might be preferentially proposed in KS adolescents when semen sampling is possible, when the patient is able to consider alternative options to become a father, and to accept germ cell retrieval failure. However, precocious diagnosis of KS has also to be considered because it might not solely improve the possibility of fertility preservation after the onset of puberty, but also the medical care and the quality of life of these patients.
