It was observed that the addition of taurine (20 mM) and manganese (150 uM) individually improved the post-thaw sperm motility, viability, membrane integrity, and acrosome integrity (Table1).
Semen at pre-freeze and frozen-thaw phase was analyzed for sperm function (motility, viability and Hypo osmotic swelling test [HOST]), acrosome damage, acrosome reaction and lipid peroxidation [LPO]) as detailed below.
The acrosome is an acidified organelle that can be specifically stained by LysoTracker probes, which spontaneously enter acrosome.

Species with external fertilization had small sperm (usually <70-[micro]m long) with a simple morphology (head with sub-spherical nucleus and caplike acrosome, midpiece with a small number of unmodified mitochondria surrounding the two centrioles.
The present study was conducted to observe the effect of royal jelly (R J) on motility, viability and acrosome integrity of spermatozoa during post-thaw incubation.
The sperm binds to the ZP and undergoes the acrosome reaction, releasing enzymes that allow penetration of zona pellucida.
