Explain the importance of the scrotum's location outside the abdominal cavity for sperm production.

Open Ended

Describe the role of interstitial cells in the testes and explain why they are important for male reproductive function.

Multiple Choice

How long does the process of spermatogenesis take, starting from the primary spermatocyte?

Multiple Choice

What is the main function of the seminiferous tubules in the process of spermatogenesis?

• To produce sperm and provide nourishment for gamete-producing cells

• To store mature sperm until ejaculation

• To transport sperm from the testes to the epididymis

• To produce testosterone

Multiple Select

Which of the following statements about meiosis during spermatogenesis are correct?

• Primary spermatocyte undergoes the first meiotic division

• Meiosis II results in four spermatids from each secondary spermatocyte

• Each secondary spermatocyte contains 46 chromosomes

• Centromere divides during Meiosis II

Open Ended

Explain the significance of the acrosome in the head of a mature sperm cell.

Multiple Choice

What happens to sperm after they are released into the lumen of the seminiferous tubule?

• They immediately fertilize an egg

• They leave the testes and enter the epididymis for final maturation

• They are stored in the prostate gland

• They disintegrate if not used

Multiple Choice

What is the primary function of the ductus deferens (vas deferens)?

• To store mature sperm

• To propel sperm through the tube via peristalsis

• To produce sperm

• To nourish sperm

Open Ended

Describe the role of the urethra in the male reproductive system.

Multiple Choice

Which gland secretes a fluid that contains fructose to provide energy for sperm?

• Seminal vesicles

• Prostate gland

• Bulbourethral gland

• Adrenal gland

Multiple Select

Which of the following are functions of the bulbourethral glands (Cowper’s glands)?

• Neutralize acidity of urine residue in urethra

• Enhance motility of sperm

• Provide lubrication for tip of penis during intercourse

• Secrete a fluid that contains fructose

Open Ended

Explain why a sperm count below 10-20 million per milliliter of semen may cause fertility problems.

Multiple Select

Which of the following are parts of the penis?

• Root

• Body (shaft)

• Glans penis

• Seminal vesicle

Multiple Choice

What physiological change occurs in the penis during sexual excitement?

• Arterioles constrict and tissue loses blood

• Arterioles dilate and tissue becomes engorged with blood

• Penis becomes flaccid

• Semen is expelled from the urethra

Multiple Select

Which of the following are functions of the sphincters of the urinary bladder during emission and ejaculation?

• Prevents semen from entering the bladder

• Inhibits flow of urine from the bladder

• Promotes sperm production

• Dilates the urethra

Open Ended

Describe the sequence of hormonal events that lead to the onset of puberty in males.

Multiple Choice

Which hormone promotes the development of male secondary sex characteristics at puberty?

• FSH

• LH

• Testosterone

• GnRH

Multiple Choice

Which of the following is NOT a learning objective for Lesson 16.2: Female Reproductive System?

• Describe oogenesis

• Identify each component of the male reproductive system

• Describe the development of ovarian follicles

• Outline the physiologic events in the female sexual response

Open Ended

Reflecting on today's lesson about the male reproductive system, what is one concept you found most interesting or would like to learn more about?

Multiple Choice

What is the difference between primary and secondary reproductive organs in the male reproductive system?

• Primary organs produce gametes, while secondary organs support gamete transport and maturation.

• Primary organs are external, while secondary organs are internal.

• Primary organs are only found in males, while secondary organs are found in both sexes.

• Primary organs are responsible for hormone production, while secondary organs are not.
