The head of the sperm cell contains the nucleus, which holds the genetic material necessary for fertilization. This is the key component that combines with the genetic material from the egg during the process of reproduction. The head is designed to penetrate the egg, and its structure is optimized for this purpose.

Inside the head, the nucleus is tightly packed with DNA, ensuring that the genetic information is delivered to the egg efficiently. In contrast, the mid-piece contains mitochondria that provide energy for the sperm’s movement, the tail is responsible for propulsion, and the acrosome, which is located at the front of the head, contains enzymes that help the sperm to penetrate the outer layers of the egg. Each of these other structures plays a crucial role in the overall function of the sperm, but it is specifically the head that houses the nucleus.
