Question

Why is the scrotum located outside the body?

Answer 1

Hint: The scrotum is a skin bag hanging between the legs, on the front of the pelvis. It is located just under the upper thighs. The testicles are in the scrotum. These are two oval glands that produce and store sperm. They are oval. It also produces various hormones, with testosterone as the main one.

Complete answer:
The scrotum hangs outside the body because it has to keep the temperature slightly lower than the rest of the body. This reduced temperature helps to keep the production of sperm. In testicles in which sperm and important hormones are produced, scrotal tissues help protect the structures.
The scrotum also protects the testes and major blood vessels, as well as tubes that emit sperm for ejaculation from the testicles.
One of the main functions of the scrotum is to keep testicular temperatures below the body temperature to provide an optimal environment for sperm generation and storage. It is generally agreed. The skin of the scrotal sack is not only fine for promoting heat dissipation but also for the arteries which blood supply the scrotum to the veins and which take blood off of the scrotum. As a result of those adjustments, human average scrotal temperatures are generally between 2.5 and 3°C (Valeri et al., 1993) below body temperature, and spermatogenesis is more efficient at 34°C.
However, the scrotum is more than just a passive refrigeration device or a cold storage system. The scrotum plays an active thermal regulation function, and there is considerable evidence. When the environmental temperature rises, not only do the testes fall but the testicles are drawn to the body to preserve the heat when the temperatures fall below a certain point. The cremasteric muscle, which the cremasteric reflex causes changes in the testicular descent and ascent at this moment.
Thus, the scrotum is located outside the body because, In humans, the ideal sperm temperature is around 3 degrees Celsius less than the inner body temperature so that external tests keep the temperature difference.

Note:
Check with your doctor if you notice any of your scrotum, testicles, or genital area:
1. Mild or severe long-lasting pain.
2. Groin pain swollen areas of activity.
3. Heavy tender areas redness, rashes, or sores.
4. Serious pain without warning in your scrotum.
5. Urination of your urine, semen, or penis drainage more than usual.
