Flow cytometric sorting of fresh and frozen-thawed spermatozoa in the western lowland gorilla

Article Abstract:

A study was performed to develop the methodologies for liquid storage of semen prior to sorting, sorting of liquid-stored and frozen-thawed spermatozoa and assessment of sorting accuracy on gorillas. The results demonstrated that fresh or frozen-thawed gorilla spermatozoa could be flow cytometrically sorted into samples, enriched for X-bearing spermatozoa.
