Male reproductive system
1. State the anatomical structures that constitute the male reproductive system and describe
their location and function.
2. Describe the structure and function of the testes, and explain the importance of their
location in the scrotum.
3. Discuss the sources and functions of sperm and semen.
4. Outline the events of spermatogenesis.
5. Discuss hormonal regulation of testicular function and the physiological effects of
testosterone on male reproductive anatomy.
Key concepts
- the structure and function of male reproductive organs
- the production of sperm and semen
- the hormonal regulation of male reproduction
Sperm – just drop their DNA and fall apart
Function = the function of sperm is to carry male genes to the females egg. To pass necessary
biological information required to produce a new organism. Consist of a head and tail which helps it
carry out its function of travelling to deliver information.
Testicles = response; be for making male gametes, sperm and the androgen hormone testosterone.
They dangle outside the abdominal cavity in the scrotum this is because:
- the testes have to be outside the body cavity to reach the lower temperature necessary for
proper spermatogenesis or sperm production
Scrotum = is a loose ouch sac of skin that hangs
below the penis and contains the testicles. It acts as
a climate control system for the testes as it control
the temperature.
Anatomy of testes
- Made up of about 250 sections called lobules
which are loaded with tightly coiled
seminiferous tubules
