The sperm cell contribute DNA to the embryo. <span>A sperm contains half of the chromosomes needed for the organism - in humans 23
Also the sperm determines if the embryo will be a male or female. If the sperm contains a Y chromosome with the required SRY gene then the embryo will become a male. BUT if the sperm contains an X chromosome then the embryo will be a female.
