title: CAG repeat length variation in the androgen receptor gene is not associated with spermatogenic failure.
abstract: Previous association studies that described the effect of an enlarged CAG repeat length in the Androgen Receptor (AR) gene on spermatogenesis could not prove or refute a true association because of methodological weaknesses. Here, we clearly show that there is no association between CAG repeat length variation and semen quality.
