Is a human sperm cell haploid or diploid?

By Zaira Salvador B.Sc., M.Sc. (embryologist).
Last Update: 11/02/2017

As explained above, spermatozoa are haploid: they contain 23 chromosomes. Both sperm cells and egg cells contain half the chromosomes contained in normal diploid cells (a.k.a. somatic cells). Haploid cells are produced during meiosis.
