The routine spermiogram in the assessment of male fertility 1. spermiograms normal by 9 variables


, : The routine spermiogram in the assessment of male fertility 1. spermiograms normal by 9 variables. International Journal of Andrology 2(6): 489-500

An analysis was made of 1214 consecutive unselected 1st spermiograms obtained from a male infertility clinic. Semen analysis methods are fully described. There were only 99 normal or perfect spermiograms when 7 criteria of normality were applied, that is a sperm count > 40 million/ml, > 60% motility, > 60% normally formed spermatozoa, > 1200 .mu.g fructose/ml, volume > 2.0 ml, pH 30 min after liquifaction from 7.0-7.6 and the absence of Spinnbarkeit or slime after liquefaction. Almost all specimens with a sperm count of > 250 million/ml, but not those of > 200 million/ml, could not be classified as normal. Lowering the normal limit to 30 million/ml or 20 million/ml introduced very few extra normal specimens. Lowering the motility limit to > 50% motile introduced a further 62 normal specimens. The characteristics of the original 99 perfect specimens are given in detail for additional parameters, e.g., qualitative motility (speed) and vitality. After incubation at 37.degree. C for 4 h the effect on quantitative and qualitative motility and on vitality is also described.
