Detailed explanation-1: -Testes are present outside the human body, in scrotal sacs because the optimum temperature required for the production of sperms is 2-3 degrees less than the body temperature. The surface area of the scrotal bags changes accordingly to them keeps the temperature inside constant.
Detailed explanation-2: -Ideally, sperm production occurs at around 93.2ºF (34ºC). This is 5.4ºF (3ºC) below normal body temperature of 98.6ºF (37ºC ).
Detailed explanation-3: -The scrotum is a sac like structure that is found in males. It contains the testis. The scrotum maintains a temperature of 2 to 3C lower than that of the body temperature as the production of sperms in the testis require a lower temperature as compared to the normal body temperature.
Detailed explanation-4: –So, scrotum maintains appropriate temperature for spermatogenesis, and thereby facilitates ideal sperm formation, which signifies the proper functioning of scrotum as well as testes. Thus the correct answer is option ‘B’ i.e. 2∘C below body temperature.
Detailed explanation-5: -Answer: Solution: The testes is located outside the abdominal cavity because sperm formation requires a temperature lower than the body temperature. It is because scrotum has a temperature 1-3 degree Celsius lower than the normal body temperature, which is essential for the production of sperm or male gametes.
