Question

Testes are extra abdominal in position. Which of the following is the most appropriate reason for this?

• A. Narrow pelvis in male
• B. Special protection from testis
• C. Prostate gland and seminal vesicles occupy maximum space
• D. $2.0-{2.5}^{\circ }C$ lower than the normal body temperature.

Answer 1

The correct option is D $2.0-{2.5}^{\circ }C$ lower than the normal body temperature.

The scrotum is a pouch-like structure of pigmented skin arising from the lower abdominal wall and hanging between the legs. Sperms develop the best when the temperature of testes is about $2.0-{2.5}^{\circ }C$ lower than the internal body, and this is the reason why the testes are the scrotal pouch outside the body.
