[Factors affecting the results of in vitro fertilization. II. The effect of andrologic factors].
We studied 297 couples in our IVF and ET programme and male factor was present in 113 cases (38%). The parameters of standard spermiograms cannot predict the fertilization potential of the specimen in vitro. However, we could demonstrate that the number of the sperm cells after the swim-up procedure correlates very well with the fertilization rate in vitro and pregnancy rate (fertilization rate 63.6% vs. 27.7% in couples with less than 1 million spermcells/ml after swim-up, pregnancy rate 20.2% vs. 5.0%). In these cases the use of the more sophisticated laboratory methods is indicated.
