Question 1

Which of the following best describes the function of the cremaster muscle in the male reproductive system?

Accepted Answer

It contracts to elevate the testes, helping regulate their temperature for optimal spermatogenesis.

Question 2

A 55-year-old male presents with difficulty urinating and increased frequency. His physician suspects an age-related change in the prostate gland. Which of the following best explains this phenomenon?

Accepted Answer

The prostate gland tends to enlarge with age, which can compress the urethra and impede urine flow.

Question 3

Which hormone is primarily responsible for stimulating Leydig (interstitial) cells to produce testosterone in the male reproductive system?

Accepted Answer

Luteinizing hormone (LH)

Question 4

During spermatogenesis, which of the following correctly matches the structure with its function?

Accepted Answer

Sertoli cells support and nourish developing sperm cells within the seminiferous tubules.

Question 5

Which of the following best describes the role of inhibin in the regulation of the male reproductive system?

Accepted Answer

Inhibin is released by Sertoli cells and inhibits FSH secretion from the anterior pituitary.

Question 6

A patient is diagnosed with a blockage in her uterine tubes. Which process is most likely to be directly affected?

Accepted Answer

The transport of the oocyte from the ovary to the uterus.

Question 7

Which phase of the ovarian cycle is characterized by a surge in luteinizing hormone (LH) that triggers ovulation?

Accepted Answer

Ovulation (midpoint of the cycle)

Question 8

Which of the following correctly matches the uterine wall layer with its function?

Accepted Answer

Myometrium: contracts during labor to expel the fetus.

Question 9

A woman’s menstrual cycle is 28 days long. On which day is she most likely to ovulate, and which hormone peaks to trigger this event?

Accepted Answer

Day 14; Luteinizing hormone (LH)

Question 10

Which of the following best explains why only one sperm typically fertilizes an egg, despite millions being released during ejaculation?

Accepted Answer

The acrosomal reaction and subsequent changes in the egg membrane prevent polyspermy.

Question 11

Which hormone is primarily responsible for maintaining the endometrial lining during the secretory phase of the uterine cycle?

Accepted Answer

Progesterone

Question 12

A patient presents with a genetic disorder affecting the development of the mesoderm during embryogenesis. Which of the following structures is most likely to be affected?

Accepted Answer

Muscles and bones

Question 13

Which of the following is a function of the placenta during pregnancy?

Accepted Answer

Exchange of nutrients and wastes between maternal and fetal blood.

Question 14

Which of the following best describes the role of human chorionic gonadotropin (hCG) during early pregnancy?

Accepted Answer

It maintains the corpus luteum, ensuring continued production of progesterone.

Question 15

A 48-year-old woman has not had a menstrual period for 14 months. Which of the following best explains the physiological changes occurring in her reproductive system?

Accepted Answer

Menopause has occurred due to the depletion of ovarian follicles, leading to decreased estrogen and progesterone production.

Question 16

Which of the following best describes the process of spermiogenesis?

Accepted Answer

The maturation of spermatids into functional spermatozoa.

Question 17

Which of the following is a secondary male sex characteristic regulated by testosterone?

Accepted Answer

Deepening of the voice due to laryngeal enlargement.

Question 18

A patient with a mutation affecting the function of granulosa cells would most likely experience which of the following?

Accepted Answer

Impaired estrogen production and disrupted follicle maturation.

Question 19

Which of the following events occurs during the proliferative phase of the uterine (menstrual) cycle?

Accepted Answer

Regeneration of the endometrial lining under the influence of estrogen.

Question 20

A blastocyst is composed of which two main cell populations, and what is the primary role of each?

Accepted Answer

Trophoblast (forms placenta) and inner cell mass (forms embryo)
