Computer assisted measurement in normal and pathological human semen, fresh and post swim-up technique.
A total of 429 semen samples were studied. Two hundred and twenty-nine samples with normal characteristics were processed following a basic procedure; the remaining 200 were normal and pathological samples that were analyzed pre and post swim-up. Semen specimens were allowed to liquefy for 30 minutes and sperm count, motility, velocity and linearity were determined using the Cellsoft Automatic Semen Analyzer. In normal patients, a significant increase of motility, velocity and linearity (p less than 0.001) post swim-up, was observed. Sperm recovery in this group was 13.9 +/- 1% of the whole motile sperm population. In the polyzoospermic group, recovery of motile spermatozoa post swim-up was significantly decreased as compared with the normal group (p less than 0.001). In the asthenozoospermic group (plus either hypospermia or hyperspermia, or with more than 30% of motile spermatozoa or less than 30% of motility), no variations of velocity or linearity as compared to the normal group were observed. In all the pathological groups studied, a significant increase in velocity and linearity (p less than 0.001) post swim-up, was observed.
