Question

“Testes are extra-abdominal in position.” Which of the following is the most appropriate reason?”

• A. Narrow pelvis in male
  
• B. Prostate gland and seminal vesicles occupy maximum space
  
• C. Special protection for testes
  
• D. $2.0-2.5°C$ lower than the
  normal body temperature
  

Answer 1

The correct option is D $2.0-2.5°C$ lower than the

normal body temperature

Male reproductive system

The male reproductive system is located in the pelvis region. It includes a pair of testes along with accessory ducts, glands and the external genitalia.

Scrotum

Scrotum is a pouch that hangs outside the body in front of the pelvis in males. Testes are present inside the scrotum which helps in maintaining the temperature $2-2.5°C$ lower than the normal body temperature for the formation of sperms (spermatogenesis).

Narrow pelvis

The male pelvis is narrower than that of the female because the distance between the ischium bones is small in males. In females the pelvis is adapted for bearing child and childbirth.

Final answer

(D) $2.0-2.5°C$ lower than the normal body temperature
