Sperm production requires an environment that is neither too hot or too cold. The cremaster muscles are those that will raise or lower the scrotal sac. If the testes are too warm, the cremaster muscles loosen and the scrotal sac will hand lower. If the testes are too cold, the cremaster muscles will control and draw them up closer to the body for warmth. So it's all about temperature control.

∙ 8y agoThe testes being outside the body is to help regulate the temperature. Too cold and the scrotum contracts and pull the testes closer to the warmer body. Too hot and the scrotum expands and sags, so allowing cooling air round the testes.

Should the testes be warmer than body temperature?
If the testes are not maintained at a temperature about 2 °C lower than body temperature the process of spermatogenesis will not take place, so that is why it is important for the testes to descend into the scrotum during maturation.
What is between the testes and penis?
Testes is balls, pennis is pen
Is the tube from the bladder to the outside of the body called the urethra meatus?
The tube leading from the bladder to the outside of the body is called the urethra.
Why is the hygrometer important?
A hygrometer is important because it shows the humidity of the atmosphere. For a hygrometer to work though it has to placed outside.
What 2 hormones are made in testes?
Estrogen and Testesterone
Should the testes be warmer than body temperature?
If the testes are not maintained at a temperature about 2 °C lower than body temperature the process of spermatogenesis will not take place, so that is why it is important for the testes to descend into the scrotum during maturation.
Why are the testes located outside the body in human?
The testes are located outside of the body because the bodies temperature is too high for the testes and the scrotum has a lower temperature for them to be able to produce sperm.
What are located outside the body in which the testes are suspended?
That's the scrotum.
What holds the testes outside the body?
The testicles are contained in the scrotum.
Why must the testes be outside of the abdominal cavity?
The temperature needed for the sperms to survive and thrive is lower than the optimum body temperature , hence it is not possible to maintain a lower temperature inside the body hence the testes are located outside the body.
Why testes are outside the body while ovaries are inside the body?

What sac are located outside the body and in which testes are suspended?
The sacs located outside the body and in which the testes are suspended are called the scrotum. The scrotum is a pouch-like structure that contains the testicles and helps regulate their temperature for proper sperm production and development.
What is the difference between ovaries and testes?
The testes are the male gonads that are located outside the body. They produce spermatozoa and testosterone. The ovaries are the female gonads that are located on the inside of the body. They produce ova, estrogen and progesterone.
Why are testes housed outside the body?
Testes are housed outside the body in the scrotum because sperm production requires a slightly lower temperature than the rest of the body. By being outside, the testes can remain a few degrees cooler, which is necessary for optimal sperm production and function.
Why is the temperature of the testes lower than core body temperature?
If the testes are not maintained at a temperature about 2 °C lower than body temperature the process of spermatogenesis will not take place, so that is why it is important for the testes to descend into the scrotum during maturation.
What is a female scrotum?
It is the 'sac' that holds the rabbits testes
It is advantageous to have human testes in the scrotum rather than in the abdomen due to?
It's due to the cooling effect of having the testes outside the main portion of the body. Testes need a slightly lower temperature than the rest of the body, for ideal functioning. Overheating will reduce fertility.
