Results: 51 cases of chromosomal abnormalities were found in 1032 male patients, the detection rate was 4.94%. Among them, there are 3 cases of sex chromosomal abnormalities, 11 cases of autosmal abnormalities, 37 cases of chromosome polymorphism changed, the 37 cases state including 8 cases of sex chromosomal polymorphism changed and 29 cases of autosomal polymorphic changed. Most clinical manifestations are weak symptoms, azoospermia and spouse repeated abortion.
