Function of the testes is to produce the male gametes or spermatozoa a. The site of spermatozoa production is the seminiferous tubules 2. The spermatozoa originate from precursor cells that are called spermatogonia a. These cells line the basement membrane of the seminiferous tubule 3. The adult male mammal that is a continuous breeder.
Males continue to produce spermatozoa throughout life.
Spermatocytogenesis and Meiosis 1. Spermatogonia divide a. After the last division, the resulting cells are termed primary spermatocytes 2. The primary spermatocytes then undergo the first of the two divisions that constitute meiosis a. The first meiotic division produces two secondary spermatocytes b. Division of the secondary spermatocytes completes meiosis and produces the spermatids 3.
