Abstract

Chromosome abnormalities, Y-chromosome microde­letions, and androgen receptor gene CAG and GGN repeat polymor­phisms in infertile Chinese men featuring severe oligospermia and azoospermia were analyzed. Ninety-six fertile men and 189 non-ob­structive infertile men, including 125 patients with azoospermia and 64 with severe oligozoospermia, were studied. Seventeen infertile men (9.0%) carried a chromosome abnormality. Twenty (10.6%) carried a Y-chromosome microdeletion. In the remainder of the patients and con­trols, GGN and CAG repeats were sequenced. Short GGN repeats (n 2.5-fold risk (OR = 2.539, 95%CI = 1.206-5.344, P
