Male Reproductive System Quiz

What is the primary function of the male reproductive system?

• To produce and store urine

• To produce, maintain, and transport sperm and protective fluid (semen)

• To regulate female hormones

• To produce blood cells

Answer explanation

The primary function of the male reproductive system is to produce, maintain, and transport sperm and protective fluid (semen), which is essential for reproduction.

Which hormone is primarily responsible for the development of male secondary sexual characteristics?

• Estrogen

• Insulin

• Testosterone

• Adrenaline

Answer explanation

Testosterone is the primary hormone responsible for the development of male secondary sexual characteristics, such as increased muscle mass, body hair, and deeper voice, distinguishing males from females.

What is the role of the testes in the male reproductive system?

• To produce sperm

• To store urine

• To produce digestive enzymes

• To regulate blood pressure

Answer explanation

The testes are essential in the male reproductive system as they are responsible for producing sperm, which is crucial for reproduction. The other options do not relate to the primary function of the testes.

Where is sperm stored after it is produced in the testes?

• Urethra

• Epididymis

• Bladder

• Seminal vesicles

Answer explanation

Sperm is stored in the epididymis after being produced in the testes. The epididymis is a coiled tube where sperm matures and is stored until ejaculation.

What structure in the male reproductive system is responsible for the production of seminal fluid?

• Urethra

• Prostate gland

• Bladder

• Kidney

Answer explanation

The prostate gland is responsible for producing seminal fluid, which nourishes and transports sperm. The urethra is a passage for urine and semen, while the bladder and kidneys are involved in urine production, not seminal fluid.

Which of the following is NOT a function of the testes?

• Production of sperm

• Secretion of hormones

• Regulation of blood glucose levels

• Production of testosterone

Answer explanation

The testes are responsible for the production of sperm, secretion of hormones, and production of testosterone. However, they do not regulate blood glucose levels, which is a function of the pancreas.

The process by which sperm cells are produced is called:

• Osmosis

• Mitosis

• Spermatogenesis

• Photosynthesis

Answer explanation

Spermatogenesis is the specific process of sperm cell production in males, occurring in the testes. Osmosis and photosynthesis are unrelated biological processes, while mitosis refers to cell division, not specifically sperm production.

Which hormone regulates the production of sperm?

• Adrenaline

• Insulin

• Follicle-stimulating hormone (FSH)

• Cortisol

Answer explanation

Follicle-stimulating hormone (FSH) is crucial for regulating sperm production in males. It stimulates the Sertoli cells in the testes, which support and nourish developing sperm cells.

The tube that transports sperm from the epididymis to the urethra is called:

• Vas deferens

• Seminal vesicle

• Eustachian tube

• Fallopian tube

Answer explanation

The vas deferens is the tube that carries sperm from the epididymis to the urethra, making it the correct answer. The other options, such as the seminal vesicle, Eustachian tube, and fallopian tube, serve different functions.
