    [Packing specification] each box for 20 tests

    [Intended use] staining of vital sperm for evaluating sperm viability  

    [Principle of test] when sperms are in hypo-osmotic solution, water molecules can pass through sperm membrane into the sperm and lead to increase volume and swelling of sperm. In particular, swelling of sperm’s tail is more obvious. Dead sperms or sperms with incomplete membrane usually don’t present swelling.

    [Major components]

    Solution A

    [Storage condition and shelf life] -20℃; 12 months

    [Applicable apparatus] optical microscope

    [Sample required] fresh or frozen semen

    (1)    Take a bottle of solution A and preheat it under 37℃ for 5 minutes;  

    (2)     Add 0.1 ml of semen sample, blend for 30 minutes, shake well, drip the mixture into slide pool (approximately 4ul), and count the percentage of swelling sperms in 200 sperms.

    [Reference value] HOS< 50 is considered as abnormal

    [Explanation of test result] when sperms are in hypo-osmotic solution, water molecules can pass through sperm membrane into the sperm and lead to increase volume and swelling of sperm. In particular, swelling of sperm’s tail is more obvious. Dead sperms or sperms with incomplete membrane usually don’t present swelling.

    [Limitation of test method] only applicable to detection of vital sperms
