Sperm are highly specialized cells, with 1, and 1, proteins identified in the sperm proteome according to previous studies. In a published study from these groups, 4 sperm samples were obtained from 32 healthy male volunteers with normal sperm production. Sperm were purified and washed to remove seminal plasma, germ-line, and other non-sperm cells. Of those proteins, 4, of those proteins were identified again in two repeat experiments. Comparisons with published sperm nucleus proteomes further validated the proteins identified.
