when it is cold the cremaster muscle contracts and draws the testes closer to the body to keep them warm.

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 arent the testes located inside the body?
Your core body temperature would prevent sperm production. Descending from the body cavity keeps the testes cool enough to function. Testicular cancer is said to be another risk, though the medical community is unsure as to whether that is related to the testes being undescended, or more related to the underlying cause of why the testes didn't descend. It is possible that having undescended testes in and of itself is not the cause for testicular cancer in those cases, but the underlying cause for the birth condition. One transsexual person decided to have SRS surgery to have a vagina created without having her testes removed. So she had the surgeon to relocate her testes inside her body. Because of the above concern about cancer, she has ultrasounds down every couple of years to inspect them.
Which gland controls formation of male body feature?
Testes... That is all
Why does the testes differ in size?
Almost no human body is exactly symmetrical
What does magnesium oxide act like?
draws fluids from the body.
What contracts to pull testes close to the body?
cremaster muslce
Why is the scrotum outside of the body?
They hang outside to control their temperature. When cold the scrotum contracts and so brings the testes closer to the body for warmth. When hot the scrotum sags so moving the testes away from the body for cooling.
Why is it important for the testes be outside the body?
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.
Why does the testes pull closer to the body when hitting cold water?
cause your body cells come close to each other
What structure helps regulate the temperature of the testes?
The scrotum is the structure that regulates the temperature of the testis. It contracts in the cold, drawing the testicles closer to the body increasing their warmth, and when it is warm it relaxes allowing the testicles to fall farther from the body, thus cooling them.
How do the scrotal muscles help maintain temperature homeostasis of the testes?
This is an interesting question. Sperm do best at temperatures slightly below the temperature of the body. This is why the testes are located outside of the abdomen. The scrotal muscles tense and relax to control the distance of the testes from the body. If it is colder they will pull the testes closer to take advantage of body heat. If it gets hotter they will relax to allow the testes to get further from the warmth of the body. Hope this helps! (BTW, they also have a reflexive action that pulls the testes close to the body when something touches the inner thigh. This does nothing to maintain a constant temperature but it does help protect them from injury.)
What adjustment is made to counteract the effects of high temperature around the testes?
The scrotum will hang lower which moves them away from the body so they cool off. When the testes are cold, they will draw closer to the body. This is a built in temperature control system
Why does a bull's testicles hang lower from the body than a horse's?
There are two reasons why. First of all, horses are animals that love to run. In order to prevent the testes from getting damaged and bruised from running, they are tucked up closer to the body. Cattle are typically too bulky and heavy to run (though there is no doubt that they are capable of running quite fast), so the testes are allowed to hang down a bit more. The second reason is that the longitudinal length of the testes of a stallion are positioned parallel to the line of the underside of the belly or the ground. This prevents the scrotum from allowing the testes to hang down so much and, anatomically speaking, makes the testes have to be held closer to the body. With a bull, on the other hand, the testes are perpendicular to the ground.
What muscle controls the scrotum closeness to the body?
The testes have to be kept at a constant temperature, a bit below the body temperature. In Winter, the testes will move closer to the body to keep warm, whilst in Summer they will move away to keep cool! Weird huh? It's almost like they have a brain of their own.
What might if the testes were located inside the body?
The sperm cells can not live in an environment that is body temperature. That is why they are usually found outside the body as they like it cooler. They will drop lower on a very warm day and will be pulled closer to the body on a very cold day.It might damage the sperms due to high temperature. Therefore, in most of the mammals testes are located outside the body.

A satellite in an elliptical orbit gains speed when it?
A satellite in an elliptical orbit gains speed as it draws closer to the central body and loses speed as it moves farther away from the central body.
