Association of abnormal length of Y chromosome with semen quality and outcome of assisted reproductive technology in humans / 中华男科学杂志

ABSTRACT

Objective@#To investigate the association of the abnormal length of human Y chromosome with semen quality and the outcome of assisted reproductive technology (ART).@*METHODS@#Based on the karyotype, we assigned the patients undergoing ART to a normal control, a long Y chromosome (Y>18), and a short Y chromosome group (Y18 group showed a significantly lower incidence rate of asthenozoospermia (31.03% vs 8.33%, P 18 and Y0.05).@*CONCLUSIONS@#Short Y chromosome may affect spermatogenesis, but the length of Y chromosome does not negatively influence the outcome of ART.
