temperature regulation in scrotum
Answers
Explanation:
The scrotum is an anatomical male reproductive structure that consists of a suspended dual-chambered sack of skin and smooth muscle that is present in most terrestrial male mammals and located under the penis.
The scrotum regulates the temperature of the testes and maintains it at 35 degrees Celsius (95 degrees Fahrenheit), i.e. two degrees below the body temperature of 37 degrees Celsius (98.6 degrees Fahrenheit). Higher temperatures affect spermatogenesis.
Temperature control is accomplished by the smooth muscles of the scrotum moving the testicles either closer to or further away from the abdomen dependent upon the ambient temperature. This is accomplished by the cremaster muscle in the abdomen and the dartos fascia (muscular tissue under the skin).
If it gets cold, the smooth muscles contract and move the testicles up closer to the body, thus increasing the heat.
If it gets hot, the smooth muscles relax and the testicles fall lower and away from the body, thus cooling.
Answer:
2-2.5 degree Celsius in scrotum
