This study reveals the feasibility of the use of a statistical model and PCA to narrow down the number of outcome measures of cryopreservation into a single score capable of reflecting post-thaw turkey semen quality. Thus, a single Sperm Quality score was able to encompass the different semen characteristics assessed (viability, osmotic-resistance and mobility) since these were positively correlated with each other.
Some authors have warned against the use of mean sperm quality variables to predict fertility or assess the effects of treatment. In contrast, the reduction of such
