A spermatid contains 23 chromosomes, which are the result of meiosis dividing the original diploid germ cell's 46 chromosomes in half. This reduction in chromosome number ensures that when the spermatid fuses with an egg during fertilization, the resulting zygote will have the correct number of chromosomes.
The ovum and spermatids are formed via meiosis (which occurs only in sex cells). From meiosis, four daughter cells are produced (in the female, three of these become polar bodies, rather than ova), each with 23 chromosomes (in humans) or the haploid number (n) in other organisms. This is significant as when fertilization occurs, the zygote (sperm + ovum) will have 46 chromosomes (or 23 pairs), the normal number for a human. So, both the ovum and spermatid are haploid sex cells (gametes), each with 23 chromosomes in humans.

The process by which a spermatid is converted into a motile sperm is called spermiogenesis. During spermiogenesis, structural changes occur that lead to the development of the tail and the formation of the acrosome, which is necessary for sperm motility and fertilization. This process involves extensive modifications to the spermatid's shape and organelles to enable it to swim and penetrate the egg for fertilization.
