Human sperm has a structure that similar harpoon in its head. It was revealed by a 14-year study recently published in the September 2015 edition of the Andrology journal.
"The findings really impress us," said John Herr, a reproduction researcher of the Department of Cell Biology, University of Virginia.

To find out, scientists "capture" proteins in a static condition. The protein crystals and then cooled to prevent degradation. By the X-ray, scientists reveal that the filaments was cylindrical with a hole in the middle.
This finding gives a new understanding of the fertilization process that filament protein turned out to be very small role in the big things, the creation of a baby. *** [EKA | FROM VARIOUS SOURCES | DAILYMAIL | TECHTIMES]
