Correlation of HOST to some conventional sperm quality parameters evaluated in frozen thawed semen of Frieswal bulls

Abstract

In this study, hypo-osmotic swelling test (HOST) was used to correlate with other sperm quality parameters such as post thaw motility, incubation test and acrosome integrity. In present investigation, the HOS test had positive significant correlation to acrosome integrity. Also the samples which had post thaw HOS test above 40% had high significant levels of post thaw motility and acrosome integrity when compared to the samples having poor HOS test response below 40%. It is likely an easy and inexpensive test to differentiate between good and poor sperms hence may be routinely used in semen stations.
