Relationships between the results of a modified sperm penetration test and a swim-up technique and the fertility of ram semen.

Abstract

Two relatively simple techniques for the objective measurement of semen quality, and which are easy to apply in the field or laboratory, have been developed: a modified sperm penetration test read by the naked eye and a colorimeter-based swim-up technique. Both the modified sperm penetration and swim-up methods produced promising results in prediction of ram fertility; the modified sperm penetration test was correlated (P<0.05) with a 48-day nonreturn rate and a 60-day conception rate; the correlation between a swim-up velocity and the 60-day conception rate approached significance (r=0.483; 0.1>P>0.05).
