title: A dicentric iso (Y) chromosome in an infertile male.
abstract: A dicentric Y chromosome was detected in a 30-year-old azoospermic male patient who was found to be mosaic for 45,X/46,X,dic Y(qter----p11::p11----qter). The dicentric iso (Y) chromosome was identified conclusively with C-banding, G-banding and Q-banding techniques. The relationship of structural abnormalities of the Y chromosome and azoospermia is discussed.
