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.

What are mature male gametes called?
Mature male gametes are called sperm. They are produced in the testes through a process called spermatogenesis. Sperm cells are involved in fertilization when they unite with a female egg cell during sexual reproduction.
How many sperm are produced in spermatogenesis?
Spermatogenesis typically produces millions of sperm per day in the testes of adult males. This process involves the continuous and rapid division of spermatogonia, which eventually differentiate into mature sperm cells.
Where does the process of sperm production, known as spermatogenesis, take place in the male reproductive system?
Spermatogenesis, the process of sperm production, occurs in the testes of the male reproductive system.
How do sperm form?
spermatogenesis
What is the name for male meiosis?
It is called spermatogenesis and for females it is called oogenesis.
Spermatogenesis results in?
Spermatogenesis is the process of making more spermatozoa.
What are the gamete-producing organs of the male reproductive system?
In gamete production meiosis is processed.
Spermatogenesis takes place within the?
Spermatogenesis occurs in the seminiferous tubules of the testis.
What is meant by spermatogenesis?
Spermatogenesis is the process by which a male (animal or human) produces sperm.
Does fsh in males initiate spermatogenesis?
Yes,fsh initiate spermatogenesis in males but in the presence of some other hormones which also play important role in spermatogenesis e.g.,lh
What are mature male gametes called?
Mature male gametes are called sperm. They are produced in the testes through a process called spermatogenesis. Sperm cells are involved in fertilization when they unite with a female egg cell during sexual reproduction.
Why does spermatogenesis happen in a male?
Spermatogenesis occurs so that the sperm can join with an egg from a female and produce offspring.
Does puberty in males have anything to do with spermatogenesis?
Spermatogenesis starts at puberty in everyone . This is because the testis become mature.
SPermatogenesis occurs in the?
Testis.
How many spermatozoa are produced at the end of spermatogenesis?
During spermatogenesis, each primary spermatocyte gives rise to four spermatozoa. This means that at the end of spermatogenesis, four functional sperm cells are produced from a single diploid germ cell.
What is the anterior pituitary hormone needed for spermatogenesis?
In men, follicle stimulating hormone starts spermatogenesis. This hormone is also abbreviated FSH.
