The Site of Spermatogenesis and the Functional Cell Types Participating (Fig. 1). Spermatogenesis is the process of producing sperm with half the number of chromosomes (hapliod) as somatic cells.

This provides genetic contributions from both parents without increasing the number of chromosomes each generation.
