WebApril 10, 2024. Sperm must swim swiftly to an egg in order to fertilize it, and so they have evolved hydrodynamic shapes. Most of the space in the head of sperm cells is taken up by the DNA they carry, so the cells coil up their DNA super tightly to stay small and streamlined. In most cell types, DNA is coiled around proteins called histones.
