Q. Name the sac in which testes are present in man.

Q.

The purpose of testes being situated outside the abdominal cavity in the scrotum is

1. To make testes less responsive to estrogen.

2. To maintain the scrotal temperature lower than the internal body temperature

3. Because the abdominal cavity is too cramped up for the growth of testes.

4. To avoid testes getting crushed or damaged by other organs.

Q.

Why are testes located in scrotal sacs outside the abdomen. Explain.

Q. explain the male reproductive system

Q.

Sperms are produced by the prostate gland.

1. True
2. False

Q. The testes in humans are situated outside the abdominal cavity inside a pouch called scrotum. The purpose served is for:

1. providing a secondary sexual feature for exhibiting the male sex
2. maintaining the scrotal temperature lower than the internal body temperature
3. escaping any possible compression by the visceral organs
4. providing more space for the growth of Epididymis

Q. Cryptorchidism is

1. Non descent of testes in scrotum
2. Removal of scrotum
3. Breaking connection of vas deferens.
4. Non development of testes

Q. Why are testes located outside the abdominal cavity in scrotum?​

1. Because sperm formation requires a higher temperature.​
2. None of these​
3. Because sperm formation requires more space.​
4. Because sperm formation requires a lower temperature.​

Q. Which is the primary reproductive organ in males?

Q.

Name the following

(i) The structure in which testes are present in man.

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

1. Prostate gland and seminal vesicles occupy maximum space
2. $2.0-{2.5}^{\circ }C$ lower than the normal body temperature.
3. Narrow pelvis in male
4. Special protection from testis
