Abstract/OtherAbstract:
OBJECTIVE: To determine the relationship between sperm motility and sperm morphology parameters and IVF and pregnancy rates. DESIGN: Pre- and postpreparation analysis of semen samples from infertile couples undergoing IVF-ET. SETTING: Andrology Laboratory, Royal Maternity Hospital, Belfast, Northern Ireland. PATIENT(S): One hundred fifty couples undergoing IVF-ET treatment at the Regional Fertility Centre. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The ability of human sperm to achieve IVF and pregnancy was investigated in relation to motility parameters (assessed with computer-aided sperm analysis [Integrated Visual Optical System] and percent normal morphology (determined with the strict criteria). RESULT(S): Significant differences were observed in motility parameters and percent normal morphology in samples that achieved > or =50% fertilization compared with < or =50% fertilization and between samples that achieved a pregnancy compared with those that did not. Significant positive correlations were observed between percent progressive motility, the velocity of sperm movement, and morphology parameters and both IVF and pregnancy. CONCLUSION(S): Both sperm motility parameters and percent normal morphology are significant factors in predicting fertilization and pregnancy rates in IVF.
