Patients admitted for treatment of in vitro fertilization (IVF) were subjected to a semen investigation about 1–2 weeks prior to actual IVF and again during IVF. In addition to routine semen analyses, the recovery efficiency of motile spermatozoa by swim‐up technique and Percoll gradient separation, the level of semen lactate dehydrogenase and the viability of the spermatozoa in the insemination medium were also studied. There is a significant correlation between the result of the pre‐IVF analyses and that observed during IVF suggesting that a prior investigation of semen profile and sperm function is useful to screen potential IVF candidates. Among the various parameters, sperm motility in the semen and the swim‐up preparation, percent normal spermatozoa and in vitro viability were significantly related to the outcome of IVF.
