Summary Introduction
Introduction:
Sperm a male gamete in humans is considered as a specialized cell type. It is a haploid cell type, and it fuses with the female ova to become a zygote by the process of fertilization. A typical human sperm’s size is 0.05 mm in length. A typical human sperm consists of a disk-shaped head part, followed by a middle segment, and the slender long tail part.
