Question 1

Which of the following best describes the main difference between mitosis and meiosis in human cells?

Accepted Answer

Mitosis produces two genetically identical diploid cells, while meiosis produces four genetically unique haploid cells.

Question 2

Which structure is the site of sperm production in the male reproductive system?

Accepted Answer

Seminiferous tubules

Question 3

Trace the correct pathway of sperm from its site of production to the external urethral orifice.

Accepted Answer

Seminiferous tubules → epididymis → vas deferens → ejaculatory duct → urethra

Question 4

Which organ contributes the largest volume to semen and what is its primary function?

Accepted Answer

Seminal vesicles; provides fructose for sperm energy

Question 5

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

Accepted Answer

Testosterone

Question 6

A patient presents with low sperm count and decreased facial hair. Which endocrine disorder is most likely involved?

Accepted Answer

Deficiency of testosterone

Question 7

Which of the following is NOT a function of the female reproductive system?

Accepted Answer

Secretion of testosterone

Question 8

What is the correct pathway for an oocyte from the ovary to the uterus?

Accepted Answer

Ovary → uterine tube → uterus

Question 9

Which of the following best describes the role of female secondary sex characteristics?

Accepted Answer

They enhance reproductive success by attracting mates and supporting pregnancy.

Question 10

A mutation causes a failure in the separation of homologous chromosomes during meiosis. What is the most likely outcome?

Accepted Answer

Some gametes will have an abnormal number of chromosomes (aneuploidy).

Question 11

Which of the following statements about semen is correct?

Accepted Answer

Semen contains secretions from the seminal vesicles, prostate gland, and bulbourethral glands.

Question 12

Which hormone stimulates the production of testosterone in the testes?

Accepted Answer

Luteinizing hormone (LH)

Question 13

Which of the following is a key difference between the male and female reproductive systems?

Accepted Answer

Females have internal fertilization structures, while males have external gamete delivery structures.

Question 14

Which structure stores sperm prior to ejaculation?

Accepted Answer

Epididymis

Question 15

Which of the following best explains why meiosis is essential for sexual reproduction?

Accepted Answer

It reduces the chromosome number by half, ensuring genetic stability across generations.

Question 16

A patient has a blockage in the vas deferens. Which process will be directly affected?

Accepted Answer

Sperm transport from the epididymis to the urethra

Question 17

Which of the following is a function of the prostate gland?

Accepted Answer

Secretion of a fluid that enhances sperm motility

Question 18

Which hormone is primarily responsible for the development of female secondary sex characteristics?

Accepted Answer

Estrogen

Question 19

Which of the following scenarios best illustrates the application of knowledge about the reproductive system in a clinical setting?

Accepted Answer

Treating infertility by addressing hormonal imbalances affecting gamete production

Question 20

Which of the following best describes the composition of semen?

Accepted Answer

Semen is a mixture of sperm and secretions from the seminal vesicles, prostate gland, and bulbourethral glands.
