The mechanism of millions of sperm cells being released and only one managing to reach to form an egg is quite an interesting topic yet the subject needs ample to understand the special behavior of these live creators. However the findings presented in the Fertility 2013 in Liverpool, UK does shed some light on the subject as reported in New Scientist.

Scientist Stephen Publicover and his colleagues from the University of Birmingham submitted the paper which was about the calcium signaling in human sperm cells. Sperms are either activated, swimming forwards in a spiral, or hyperactivated, thrashing wildly while trying their best to enter the egg. They need to be self stimulative as they have to cross over various hurdles to achieve their target an mostly only one succeeds.

As per the findings, 'Sperm cells appeared to be triggered when calcium enters through ion channels in the tail. When calcium is released from organelles inside the neck of the cell into the surrounding cytoplasm, the sperm became hyperactivated.'  The phenomenon was verified by the team in a simple process which most scientists are sure to agree with.
