Do saliva have cells

If you're meaning saliva, as in the substance produced in your mouth, then no. A sperm cell is the male reproductive cell, or the male gamete, which conjoins with the female ovum to form a zygote and eventually a fetus, baby etc. They contain 23 chromosomes, including an X or Y to determine the sex, which will conjoin with the ovum's 23 chromosomes to determine the characteristics of the child. Sperm cells are only produced within the male testes and are therefore not present in saliva.
