His wife was physically fit, her menstruation was regular, no abnormalities were found in the gynecological examination, the left and right testicles were about 10 and 12 ml respectively, no abnormalities were found in the epididymis, and the varicocele on the left side was 1 degree. Auxiliary examination: prostatic fluid routine is normal, sex hormones are normal. Tongue and pulse: slightly red tongue, slightly greasy coating, thin pulse.
