ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the efficiency of density gradient and improved swim-up methods for motile sperm isolation from fresh semen samples in intracytoplasmic sperm injection and embryo transfer (ICSI-ET) program, thus guiding the clinical application.</p><p><b>METHODS</b>The fertilization rate, cleavage rate, high-quality embryo rate, clinical pregnancy rate, sperm abnormal rate and recovery rate of 42 cycles were studied prospectively. The cycles were divided into two groups with respect to the motile sperm isolation methods.</p><p><b>RESULTS</b>No obvious difference was found in the fertilization rate, cleavage rate, high-quality embryo rate and clinical pregnancy rate between the two methods. The abnormal sperm rate induced by the improved swim-up method was significantly higher than that of the density gradient method (P < 0.01). For severe oligozoospermia, the recovery rate of motile sperm with density gradient was higher than that of improved swim-up (P < 0.01).</p><p><b>CONCLUSION</b>In the ICSI-ET, there is no obvious difference in clinical pregnancy outcome between the two methods. The method of improved swim-up can be used for all patients but those with severe oligozoospermia.</p>
