Question 1

Which of the following best describes the role of luteinizing hormone (LH) in the female reproductive system?

Accepted Answer

LH triggers ovulation and promotes the formation of the corpus luteum.

Question 2

A patient presents with low sperm count and decreased testosterone levels. Which structure is most likely dysfunctional?

Accepted Answer

Testes

Question 3

Which hormone is primarily responsible for stimulating spermatogenesis in males?

Accepted Answer

Follicle-stimulating hormone (FSH)

Question 4

During the menstrual cycle, which event is most directly triggered by a surge in LH?

Accepted Answer

Ovulation

Question 5

Which of the following structures is responsible for producing the majority of seminal fluid?

Accepted Answer

Seminal vesicles

Question 6

A male patient has a blockage in the vas deferens. What is the most likely consequence?

Accepted Answer

Reduced sperm transport from the epididymis to the urethra

Question 7

Which equation best represents the hormonal regulation of the ovarian cycle?

Accepted Answer

$$GnRH \rightarrow FSH, LH \rightarrow Estrogen, Progesterone$$

Question 8

Which anatomical feature is shared by both male and female reproductive systems?

Accepted Answer

Gonads

Question 9

A female patient has elevated levels of FSH but low estrogen. Which process is most likely impaired?

Accepted Answer

Follicular development

Question 10

Which of the following best explains the adaptive advantage of being a placental mammal?

Accepted Answer

Placental mammals provide continuous nutrient and waste exchange between mother and fetus.

Question 11

Which hormone is secreted by the corpus luteum and is essential for maintaining the endometrial lining during early pregnancy?

Accepted Answer

Progesterone

Question 12

A patient is diagnosed with polycystic ovary syndrome (PCOS), which disrupts normal ovulation. Which hormone imbalance is most commonly associated with this condition?

Accepted Answer

High androgen and low FSH

Question 13

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

Accepted Answer

Secretion of alkaline fluid to neutralize vaginal acidity

Question 14

Which structure in the female reproductive system is the site of fertilization?

Accepted Answer

Uterine tube (fallopian tube)

Question 15

Which equation best represents the process of spermatogenesis?

Accepted Answer

$$Spermatogonia \xrightarrow{Mitosis} Primary\ Spermatocytes \xrightarrow{Meiosis\ I} Secondary\ Spermatocytes \xrightarrow{Meiosis\ II} Spermatids \xrightarrow{Differentiation} Sperm$$

Question 16

A patient has a mutation that prevents the secretion of inhibin. What is the most likely effect on spermatogenesis?

Accepted Answer

Increased FSH levels and enhanced spermatogenesis

Question 17

Which of the following best describes the function of the acrosome in sperm?

Accepted Answer

It contains enzymes that help penetrate the egg during fertilization.

Question 18

Which hormone is responsible for the development of secondary sexual characteristics in males?

Accepted Answer

Testosterone

Question 19

Which of the following changes would you expect to see in the reproductive system as a consequence of menopause?

Accepted Answer

Decreased ovarian follicle number and reduced estrogen levels

Question 20

Which equation best represents the negative feedback regulation of FSH in males?

Accepted Answer

$$FSH \rightarrow Spermatogenesis \rightarrow Inhibin \rightarrow \downarrow FSH$$
