Application of multiplex bead array assay for Yq microdeletion analysis in infertile males.

The purpose of this study was to apply the multiplex bead array as a diagnostic tool for male infertility. The multiplex bead array offers a new platform in high-throughput nucleic acid detection. Six loci, including sex-determining regions on the Y (SRY) chromosome as a control and five sequence-tagged sites (STS) in azoospermia-factor regions, were used in this system.
