Now that we know all about the female and male reproductive system, we shall now learn about how they work together to make reproduction possible.
Reproduction starts when the male organ enters the female organ. The scientific term for this process is 'mating'. It is also called Coitus or Copulation.
During mating, the muscles of the male organ are filled with blood and become erect. Erection can happen anytime, even when there is no mating activity.
The glands at the head of the male reproductive organ swells and the testes enlarge. The stimulation of the male organ causes an orgasm (muscles of the male organ suddenly relaxes). At orgasm, the male sperm cells are released into the female. The proper term for this is 'ejaculation'.
During mating, the brain prepares both male and female organs for this act. In women, the brain causes the walls of the female organ to enlarge and lubricate itself. Lubrication in the female organ is important for the male organ to do its job. It is important to note that mating is all controlled by the brain, telling both male and female organ parts what to do and when to do something.
