Title: Does computerized image analysis of sperm movement enhance the predictive value of semen analysis for in‐vitro fertilization results?
Abstract: Summary The influence of semen quality on fertilization rates in an in‐vitro fertilization (IVF) programme was studied by analysing both conventional semen parameters and computerized movement characteristics. The study was based on 407 inseminated oocytes which were obtained from 50 patients in 113 laparoscopies. Sperm concentration did not correlate strongly with the fertilization rate. Sperm motility and morphology were the most meaningful parameters in predicting fertilization success. A drop in fertilization rate was found when sperm motility or normal morphology were below 40%. Sperm velocity measured in semen was the only sperm movement parameter which correlated with the fertilization rate, albeit weakly. The latter was reduced when average sperm velocity in semen was < 50 μm/sec. Conventional semen parameters seem to be more predictive of the fertilizing potential of an ejaculate than movement characteristics obtained by computerized image analysis.
