What are the mature male gametes called that contain the haploid number of chromosomes?

Mature male gametes are referred to as spermatozoa. During the process of spermatogenesis, diploid precursor cells undergo meiosis to produce haploid sperm cells. The process results in the formation of spermatozoa, which are the fully formed, motile male gametes ready for fertilization. These spermatozoa contain half the number of chromosomes compared to the diploid somatic cells, which is essential for sexual reproduction, as fertilization involves the merging of a haploid sperm and a haploid ovum to restore the diploid state in the zygote.

Spermatocytes are not the mature gametes; they are intermediate cells in the process of developing into spermatozoa. Ova refers specifically to female gametes and do not apply to the question about male gametes. Gametes, in a general sense, refer to reproductive cells but do not specify the male gametes, making spermatozoa the correct and precise term for mature male gametes containing the haploid number of chromosomes.
