Production of sperm is reduced. The testicles need to be cooler than core body temperature for the production of numerous and viable sperm.
The cremaster muscle contracts and pulls the testes closer to the body to regulate temperature. This action helps to keep the testes warm and within the optimal temperature range for sperm production.
No, it will not. The sperm are housed outside of the body because it is too warm inside. If it becomes too warm, the sperm will die. If it is way too cold, it will die as well.
As time passes, some of the ice melts, and the drinks become less warm.
Infertility can be the result.

If the testes don't descend (drop) after birth, then the male can become sterile (infertile), and the risk of testicular cancer increases.
Gametogenesis occurs in the gonads. Spermatogenesis happens in the testes, and oogenesis in the ovaries.
The testes can only produce functional semen at a certain temperature. If they were in the abdomen, the environment would be too warm. Since the scrotum is only a thin piece of skin, the testes are contained in an environment that is the perfect temperature.
When ice is exposed to warm air, the ice will begin to melt and become a liquid once more
The cremaster muscle and the dartos muscle help regulate the temperature of the testes by moving the testes closer to the body to keep them warm or away from the body to cool them down. The testes are located outside the body in the scrotum, which helps maintain a lower temperature than the rest of the body, which is crucial for sperm production.
you get warm
Blood vessels in the scrotum and around the testes constrict or expand based on the outside temperature. The spermatic cord also is useful in contracting when temperatures are too cold for the testes to stand and thus need to be pulled more into the body cavity to be warm, or relaxing when it's warm enough that the testes need to be away from the body cavity to stay cool.
