Investigation of AZF microdeletions in patients with Klinefelter syndrome
We investigated azoospermia region microdeletions in male infertility patients with Klinefelter syndrome (KFS), as well as the association between azoospermia symptoms in patients with KFS and Y chromosome microdeletion polymorphisms. A total of 111 cases with male infertility confirmed to have KFS (47, XXY) and 94 fertile men were included in this study. Peripheral blood was drawn and DNA was extracted from these samples. Multiplex polymerase chain reaction was performed to screen the partial deletions of 25 sequence-tagged sites on the Y chromosome.
