ABSTRACT

OBJECTIVE@#To evaluate the fertility of infertile males of large samples by the routine semen examination, and to provide a scientific basis for clinical treatment of male infertility and improve efficacy.@*METHODS@#We collected 16 835 semen specimens of infertile man in our hospital (the infertility group), and 1 567 semen specimens of sperm donating candidates from the sperm bank of our hospital (the control group). Semen routine examination was performed by computer-assisted semen analysis (CASA) technology, and the data of semen routine examination were analyzed statistically.@*RESULTS@#The infertile patients with semen abnormalities in our hospital mainly suffered asthenospermia. The proportion of azoospermia, asthenospermia and oligoasthenospermia in the infertility group was higher than that in the control group, while the proportion of oligozoospermia was lower than that in the control group (P<0.001).@*CONCLUSION@#Azoospermia, asthenospermia and oligoasthenospermia are related to infertility, but simply oligozoospermia is not necessarily related to infertility.
