How much DNA does a sperm contain?

Each sperm cell in a human male is heterogametic and haploid, meaning that it contains only one of two sex chromosomes (X or Y) and only one set of the 22 autosomal chromosomes. Thus, each sperm contains about 3 billion bases of genetic information, representing 750 Mbytes of digital information.
