Objectives: Artificial insemination with sperm preparation and inseminate to the uterus is a common method of infertility treatment. Currently two methods used for sperm washing is “swim-up” and “gradient”. Materials and methods:cross-sectional description in 166 cycles of artificial insemination in Hue University Hospital from April, 2012 to March, 2013 in order to compare effectiveness between “swim-up” and “gradient” methods. Samples were collected randomly into two methods. Results:Results of sperm preparation in both methods are equivalent in terms of the following parameters total sperm count, total number of progressive sperm, total good morphology sperm. However, “gradient” method results in higher number of progressive sperm in case with slow motility (38.3% vs. 26.1%) or abnormal morphology (34.9% vs. 19.7 %) compared with “swim-up” method. Pregnancy rates after artificial insemination were similar between two preparation methods. Conclusion:In case of slow motility sperm and abnormal morphology, “gradient” method should be used to increase the number of progressive sperms. Pregnancy outcome depends on many factors other than preparation methods.
