Which of the following are accessory sex structures in the male?
a. Gonads
b. Gametes
c. Broad shoulders
d. Semical vesicles
Introduction:
Male reproductive system is composed of two types of organs. One is the primary sex organs that are involved in the production of sex hormones (testosterone) and the male gamete. The other one is accessory male organs that produce and nourish the male gamete. Accessory male organs are internal structures present in the males, which includes, seminal vesicles, vas deferens, and prostate gland.
Answer to Problem 1MC
Correct answer:
Seminal vesicles are the accessory sex structures in the male.
Explanation of Solution
Explanation for the correct answer:
Option (d) is given that seminal vesicles are the male accessory sex organs. Seminal vesicles are hollow glands that are the accessory glands in the males. They secrete seminal fluid, rich in components such as prostaglandins, fructose, and vitamin C. Seminal fluid nourishes sperms. Hence, option (d) is correct.
Explanation for incorrect answers:
Option (a) is given that gonads are the male accessory sex organs. However, gonads (testes in case of males) are known as the primary sex organs. They produce sex hormones and gametes. So, it is an incorrect option.
Option (b) is given that gametes are the male accessory sex organs. Gametes (sperms in case of male) are produced from the primary sex organs and are not accessory sex organs. So, it is an incorrect option.
Option (c) is given that broad shoulders are the male accessory sex organs. Broad shoulders are the secondary sexual characteristics in the male induced by the release of hormones. They are not male accessory organs. So, it is an incorrect option.
Hence, options (a), (b), and (c) are incorrect.
Seminal vesicles are the male accessory organs, which produce seminal fluid and nourishes the sperm.
