The present study was designed to evaluate the ability of hyaluronic acid binding sperm (HABS) in increasing the efficiency of intracytoplasmic sperm injection (ICSI) in terms of the production of chromosomally normal porcine embryos. Porcine embryos were produced by in vitro fertilization (IVF), ICSI and ICSI using hyaluronic acid binding sperm (ICSI-HABS). Chromosome aneuploidy in sperm and embryos was evaluated using chromosome 1 submetacentric probe for fluorescence in situ hybridization (FISH) analysis. No significant differences were observed in the blastocysts rates (18.6, 23.6 and 23.8%) and cell numbers (61.8+/-12.5, 55.5+/-7.3 and 59.3+/-9.6) among embryos derived from IVF, ICSI, and ICSI-HABS. However, the frequency of normal diploidy in ICSI-HABS (75.5%) was significantly higher (P<0.05) than that in IVF (57.0%) and ICSI (68.2%). Embryos from ICSI-HABS showed significantly lower chromosome abnormality rate (P<0.05). Both ICSI and IVF embryos showed higher rates of polyploidy, and hence chromosomally abnormal embryos, in comparison to ICSI-HABS embryos. In addition, we investigated the chromosomal complement of porcine spermatozoa by FISH. The rate of chromosome number abnormality in porcine sperm was found to be 6.25% (70/1120). Thus, we conclude that the use of hyaluronic acid binding sperm is superior to morphological sperm selection for ICSI in producing chromosomally normal embryos and increasing the ICSI efficiency by lowering the aneuploidy frequency. Our results indicate that the selection of normal sperm with hyaluronic acid binding assay might help to reduce the early embryonic mortality due to chromosomal aneuploidy thereby increasing the success rate of embryo transfer technology in pigs.
