Viruses are MUCH smaller than cells in size.
It depends on their size.
The differ based on the kind of sediment that they are composed of, the color of their sediment, and the size of their sediment.
The size will differ between boys.
Ostriches have their testes inside of them, not outside. As for size, they could be about the size of a baseball.
No, the size is irrelevant for having sex.
They differ in shape ,size and even colour
Body parts differ in shape and size due to evolutionary pressure and physical need.
In any male animal the testes will grow to an average size during adolescence and that is normal and their size can not be reduced. If however one of your testes (a testis) has recently enlarged, you should go and see a qualified medical practitioner (A Doctor) as soon as possible. This is not normal and can have a variety of causes most of which need treatment.
Testes
Size and Length
AAS (Anabolic/Androgenic) Steroids can cause testes to shrink because artificial testosterone is introduced into the body which causes the testes to stop producing natural testosterone. This is called testicular atrophy, usually after someone stops using the steroid the body will start to produce natural testosterone again after this testes should return to normal size.
The testes produce sperm, which is the male sex cell. The ovaries produce ovum, which are the female sex cell. The sperm fertilizes the ovum in order to create a gamete, this gamete will then develop to form a new life.
Only to a degree. If you have a certain size and they get smaller, you might have some fertility or hormonal issues. But overall, testicle size does not affect the amount of semen you produce.
A mature fertile bull's testicles, both measured together, should be between 35 cm and 40 cm in circumference. Naturally, this differs with the breed and size/weight of the bull. Small bulls tend to have smaller testes, whereas most large bulls tend to have larger testes.
