SpermMobil
Spermmobil is a special solution that accelerates the movement of seemingly immobile sperm for a short time. Some sperm move very slowly or not at all but still retain the ability to fertilize an egg. By adding sperm mobile solution to a sample of the mobile sperm, their mobility is immediately activated.
The stimulating effect of sperm mobile will help identify living but otherwise immobile sperm, thus increasing the chances of fertilization.
