What is spermatogenesis?

Answer 1

Spermatogenesis is the development of mature spermatozoa (sperm cells) from spermatogonia; it includes spermatocytogenesis and spermiogenesis.

• In the testes there are seminiferous tubules
• Seminiferous tubule surrounded by epithelium
• On epithelium are SPERMATOGONIA cells
• These are diploid cells
• Divide by mitosis
• Some remain in epithelium as more spermatogonia
• However, some move towards middle of tubule
• They grow larger and are now called PRIMARY SPERMATOCYTES
• They undergo meiosis I to create
• SECONDARY SPERMATOCYTES which are haploid
• 2-3 days later meiosis II occurs to create
• SPERMATIDS
• These begin to differentiate
• They are enveloped by the Sertoli Cells and undergo SPERMIOGENESIS
• This gives them their characteristic shape from a round cell to the head and elongated tail. The cytoplasm is remodeled. This creates
• SPERMATOZOA

Note: The production of egg cells, the female counterpart to spermatogenesis, is called oogenesis.

Answer 2

Spermatogenesis is the process by which male germ cells, known as spermatogonia, develop into mature sperm cells in the testes. This process involves multiple stages, including mitotic division, meiotic division, and sperm maturation, to produce functional sperm capable of fertilizing an egg.

Answer 3

Spermatogenesis is the process during which spermatozoa cells are produced. They are critical in the process of meiosis, which is responsible for reproduction in animals and plants.

Answer 4

Spermatiogenesis is the process of producing sperm and oogenesis is the process of producing egg cells.
fertilization

Answer 5

Spermatogenesis is the process by which sperm is made and oogensis is the process by which an egg is made. Obviously spermatogenesis occurs in males and oogensis in females

Answer 6

What causes spermatogenesis

Answer 7

it is the process of formation of sperms
