摘要: The clinical fertility of 1,077 men whose semen had been analyzed between 1950 and 1952, in terms types abnormal spermatozoa morphology according to the Hammen system with 14 types, was studied 20 years later by means a questionnaire (785 replies i.e., 72.9%). There significant difference (P less than or equal 0.01) couples who obtained living children did not, expressed as mean percentages narrow heads, round amorphous irregular abortive forms, double staining abnormalities vacuoles. same tendency found for piriform small belted heads various rare heads. Giant head showed no difference, pinhead not represented. Piriform increased significantly more other increasing total number spermatozoa. relation any type abortions otherwise pregnancies. Detection does seem improve analysis predicting chance pregnancy, we prefer use percentage morphologically normal spermatozoa, inverse expression spermatozoal total, routine analysis.
