Sperm cell haploid

Whereas in human females the total pool of oocytes is produced before birth, in males new germ cells enter meiosis continually from the time of sexual maturation, with each diploid primary spermatocyte giving rise to four haploid mature sperm. Meiosis chemoreception and directed-movement In chemoreception: However, in some species of animals, a single individual can be both male and female, using both ovaries and testes to produce both eggs and sperm. The sperm subsequently pass into the epididymis, a coiled tube overlying the testis, where they undergo further maturation and are stored.
