Streamlined body - The sperm has a streamlined body that allows it to move rapidly to reach the target egg cell. For instance, the head has a tapering apex which helps reduce drag as the cell travels in the female reproductive tract.
Moreover, how does the shape of a sperm cell help its function?

Secondly, how is a sperm cell adapted and why? For example, sperm cells are produced in large numbers to increase the chance of fertilisation. Sperm cells have these adaptations: a tail to move them towards an egg cell. an acrosome (part of the tip of the head) that releases enzymes to digest the egg membrane.
Also asked, why is the sperm cell shaped like that?
The shape of the sperm is a reflection of proper sperm development (spermatogenesis) in the testicles. Men with defective spermatogenesis may produce a high percentage of abnormal sperm. There are many factors that can lead to formation of abnormal sperm.
How does the structure of sperm cell?
Sperm usually consist of two morphologically and functionally distinct regions enclosed by a single plasma membrane: the tail, which propels the sperm to the egg and helps it to burrow through the egg coat, and the head, which contains a condensed haploid nucleus (Figure 20-25).
