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. The process of spermatogenesis then allows the recombination of male and female haploid gametes at fertilization. This provides genetic contributions from both parents without increasing the number of chromosomes each generation.
