Acrosome human sperm
With this technique a probe for viability, like propidium iodide PI could also be included in order to exclude dead cells from the acrosome assessment, since many sperm cells will spontaneously lose their acrosome when they die.
The aforementioned process describes the physiologically relevant events.
Assessment[ edit ] Birefringence microscopy,  flow cytometry  or fluorescence microscopy can be used for assessing the shedding of the acrosome or "acrosome reaction" of a sperm sample.
In order to prevent polyspermy and minimise the possibility of producing a triploid zygote, Acrosome human sperm, several changes to the egg's cell membranes renders them impenetrable shortly after the first sperm enters the egg.
Part of the sperm's cell membrane then fuses with the egg cell's membrane, and the contents of the head sink into the egg.
A few events precede the actual acrosome reaction.
The delivery rate per cycle follows the same trend.
