[Relationship between sperm motility parameters and sperm morphology].
OBJECTIVE
To evaluate the relationship between sperm motility parameters and sperm morphology.


METHODS
Seven hundred and eighty-three semen samples were tested. Sperm motility parameters were analyzed by computer-aided sperm analysis (CASA) , and sperm morphology assessed by automated sperm morphology analyzer (ASMA). The cases were classified based on the World Health Organization criteria. Morphologically 241 of the samples were normal and the other 542 abnormal.


RESULTS
VCL, WOB, VAP of the morphologically abnormal group were significantly higher than those of the normal group (P < 0.05, P < 0.001), while MAD, LIN, STR of the abnormal group were significantly lower (P < 0.05, P < 0.001). There were significant positive correlations between the morphologically normal sperm rates and MAD, LIN, WOB, STR, and a significant negative correlation between the morphologically normal sperm rate and ALH.


CONCLUSIONS
Morphological abnormality of sperm is often accompanied with weak motility, which is probably attributed more to some factors that coact on both sperm motility and morphology than to the influence of sperm morphological abnormality on sperm motility.
