Application of sperm morphology analysis in diagnosing male infertility

Objective To investigate the application of sperm morphology analysis to the diagnosis of male infertility.Methods The infertile couples in out-patient department from July 1,2008 to June 29,2010 were selected.All males underwent semen analysis for at least 2 times and sperm morphology analysis for 1 time.Results Total 402 cases of semen analysis and 173 cases of sperm morphology were analyzed.Sperm concentration was 0-180×109/L,with anaverage of(55.3± 32.21)×109/L,75.1% were with in 20-100×109/L,only 13.3% were oligozoospermia,and azoospermia accounted for 1.5%;51.1% of the cases had 30%-50% rapid progressive sperms(a grade+b grade),and only 0.6% were normal according to the WHO standard(a grade+b grade50%).Only 20.5% of the cases had14% normal sperm morphology.Conclusion Azoospermia is obviously related to infertility.Asthenospermia or high sperm deformity may predict the infertility factors.Analysis of semen and spermmorphology should be used as the fIrst screening method for out-patient infetile couples to prevent excessive treat ment.
