Abstract

To improve artificially the quality of poor sperm samples to be used in assisted procreation procedures, Test Yolk Buffer (TYB) incubation effect was investigated. After adding the TYB procedure to the standard swim-up technique, a significant (P <0.001) increase in spermatozoa velocity was observed, while the other seminal parameters were not affected. Three of 11 couples who had not had success after three intraperitoneal inseminations (IPI) with sperm prepared by the usual swim-up technique obtained pregnancies after IPI with TYB-incubated spermatozoa. These preliminary results suggest that TYB incubation for capacitated spermatozoa be employed in the assisted procreation strategies applied for male infertility.
