Male Infertility Associated with a Supernumerary Marker Chromosome

Abstract

A marker chromosome (mar) is a structurally abnormal chromosome in which no part can be identified. The significance of a marker varies, depending on the material contained within the marker. Very few reports have been published of marker chromosomes associated with male infertility. Here, we report the case of an infertile man with a rare variant of a marker chromosome of a mos 47,XY,+mar[25]/46,XY[25] karyotype.
