Abstract
Comparing motility parameters with a trans-membrane migration method and a Hamilton-Thorn HTM-2000 computer assisted semen analyzer, we found that trans-membrane migration ratio (TMMR) correlated best with critical motility which indicated the fraction of fastest and straightest sperm in a semen sample. We also found that TMMR correlated better with progressive velocity than with track speed. It is concluded that nonprogressive sperm were not included in the estimation of TMMR and the trans-membrane migration method is most suitable for studying drug effect on straight and rapid sperm motility.
