Question 1

Which of the following best describes the main function of the seminiferous tubules in the testes?

Accepted Answer

They are the site of sperm cell production through spermatogenesis.

Question 2

During which phase of meiosis does crossing over, which increases genetic variability, primarily occur?

Accepted Answer

Prophase I

Question 3

A patient presents with a mutation that prevents the production of FSH. Which process in the male reproductive system would be most directly affected?

Accepted Answer

Spermatogenesis in the seminiferous tubules

Question 4

Which structure in the female reproductive system is responsible for picking up the ovulated secondary oocyte and is lined with cilia to aid in transport?

Accepted Answer

Uterine (fallopian) tube

Question 5

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

Accepted Answer

Testosterone

Question 6

A sperm cell contains 23 chromosomes. Which process ensures this chromosome number?

Accepted Answer

Meiosis

Question 7

Which of the following best explains why only one mature ovum is typically produced from a primary oocyte during oogenesis?

Accepted Answer

The other cells become polar bodies and degenerate.

Question 8

Which of the following is a direct result of the surge in luteinizing hormone (LH) during the female reproductive cycle?

Accepted Answer

Ovulation of the secondary oocyte

Question 9

A male patient has a blockage in his ductus (vas) deferens. Which of the following would most likely be impaired?

Accepted Answer

Transport of sperm from the epididymis to the urethra

Question 10

Which of the following best describes the role of the acrosome in a sperm cell?

Accepted Answer

It contains enzymes that help penetrate the oocyte.

Question 11

Which of the following equations correctly represents the chromosome number in human gametes after meiosis?

Accepted Answer

$$n = 23$$

Question 12

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

Accepted Answer

Secretes a thin, milky fluid that enhances sperm motility

Question 13

Which of the following best explains the physiological mechanism of penile erection?

Accepted Answer

Parasympathetic impulses release nitric oxide, dilating arteries and compressing veins.

Question 14

Which of the following is a correct sequence of events during the menstrual (uterine) cycle?

Accepted Answer

Proliferative phase → Secretory phase → Menstrual phase

Question 15

A woman experiences a decline in estrogen and progesterone levels. Which event is most likely to occur next in her reproductive cycle?

Accepted Answer

Menstrual flow

Question 16

Which of the following best describes the function of the scrotum?

Accepted Answer

It maintains the testes at a temperature lower than body temperature for optimal sperm production.

Question 17

Which hormone is primarily responsible for stimulating the thickening of the endometrium during the proliferative phase of the menstrual cycle?

Accepted Answer

Estrogen

Question 18

Which of the following is a direct effect of inhibin secreted by sustentacular cells in the male reproductive system?

Accepted Answer

Inhibits secretion of FSH from the anterior pituitary

Question 19

Which of the following best explains why genetic variability is increased during meiosis?

Accepted Answer

Crossing over and independent assortment during meiosis I

Question 20

A patient has a mutation that prevents the formation of the corpus luteum. Which hormone would be most directly affected?

Accepted Answer

Progesterone
