In humans, sperm are produced in the

a. spermatophore.
b. seminiferous tubules.
c. epididymis.
d. urethra.

Expert Solution & Answer

Summary Introduction

Introduction:

The male reproductive system consists of the testes which produce sex hormones and sperm; glands that secrete the substances which nourish and activate the sperm, and tubes that collect the sperm and conduct them out of the body. The sex hormone such as testosterone and sperm are produced at the beginning of the puberty.

Answer to Problem 1MC

Correct answer:

In humans, sperms are produced in the seminiferous tubules. Therefore, option (b) is correct.

Option (b) is given as “seminiferous tubules”.

Explanation of Solution

Justify reason for the correct statement:

Sperms are produced in the testes, and each testes is filled with the coiled structure, called the seminiferous tubules in which sperm are produced. The inner lining of the seminiferous tubules contains two types of cells, the stem cells called the spermatogonial stem cells, which produce sperm, and the Sertoli cells which nourish the developing sperm.

Hence, option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “spermatophore”.

Spermatophore is a protein capsule which contains a mass of spermatozoa. So, sperm is not produced in the spermatophore. Hence, it is a wrong answer.

Option (c) is given as “epididymis”.

Epididymis is a long folded tube-like structure in which sperm are stored and mature further. Hence, it is a wrong answer.

Option (d) is given as “urethra”.

The urethra conducts urine and sperm out of the body during urination and ejaculation respectively. Hence, it is a wrong answer.

Hence, options (a), (c), and (d). are incorrect.

Conclusion

Hence, sperms are produced in the seminiferous tubules. The inside wall of the seminiferous tubules contains the stem cells called the spermatogonial stem cells, which produce sperm.
