One in every men is born with an extra X chromosome, with a karyotype of 47, XXY rather than the typical 46, XY male karyotype. Men with pure Klinefelter Syndrome are nearly universally azoospermic with a sperm count of zero in the semen due to a lack of adequate sperm production in the testicles. Just nearly two decades ago these men were told they could not be fathers with their own sperm, but things have dramatically changed in our understanding since then. The embryologists from Westlake IVF join him in the operating room for this highly specialized search for sperm microsurgically throughout the testicles.
Men with Klinefelter Syndrome Can Still Be Fathers Using Own Sperm Through MicroTESE

Study record managers: refer to the Data Element Definitions if submitting registration or results information. Clinical findings are nonspecific during childhood; thus, the diagnosis commonly is made during adolescence or adulthood in males who have small testes with hypergonadotropic hypogonadism and gynecomastia. Virtually all men with Klinefelter syndrome are infertile. Approximately one in 1, boys is born with an additional X chromosome,XXY, the karyotype that causes Klinefelter syndrome. This karyotype is detected at or before birth in 10 percent of affected boys, and it is found during adulthood in 25 percent of affected men.

Klinefelter syndrome is the most common chromosomal male anomaly associated with male infertility. This review focuses specifically on non-obstructive azoospermia secondary to Klinefelter syndrome and discusses controversies surrounding fertility management in patients with this genetic disorder.
Background: Klinefelter syndrome KS 47,XXY is the most common sex chromosomal disorder, and it is a frequent form of male hypogonadism and infertility. Although the majority of these patients are azoospermic, they might have severe oligozoospermia or residual single-residual foci with spermatogenesis in the testis. Aim: We report our experience on sperm retrieval in the ejaculate and testis, and evaluate the frequency of chromosome abnormalities in sperm of KS.
