The present study investigated the frequency of chromosome aberrations and AZF microdeletions in infertile patients with nonobstructive azoospermia (NOA) or severe oligozoospermia.
In this study, a large-scale analysis of AZF microdeletion in a total of 630 Chinese males, including healthy semen donors (n=200), infertile males with normal sperm count (n=226) and patients with either nonobstructive azoospermia or severe oligozoospermia (n=204), was performed.
