Understand the process of spermatogenesis, which is the production of sperm cells in the male reproductive system.
Identify the starting cell type: Spermatogonia are the initial germ cells that undergo mitosis to maintain the germ cell line and produce primary spermatocytes.
Recognize that primary spermatocytes undergo the first meiotic division to form secondary spermatocytes.
Note that secondary spermatocytes undergo the second meiotic division to produce spermatids.
Finally, understand that spermatids undergo a series of changes known as spermiogenesis to become mature spermatozoa.
