Questions
Briefly describe the process of spermatogenesis.
Explain the process of spermatogenesis in humans.
Solution
Spermatogenesis is the process of producing spermatogonia from the germinal epithelium (primordial germ cells) via mitosis (multiplication phase). Finally, they stop going through mitosis and mature into primary spermatocytes (growth phase). Each spermatocyte passes through meiosis (the maturation process). The first maturation division is reductional, resulting in two secondary spermatocytes. The latter divides by equational division (second maturation division) to produce four haploid spermatids. Sertoli cells nourish spermatids, which then produce sperms. This process is known as spermiogenesis. During this process, one spermatogonium generates four sperms with half the amount of chromosomes.
