Question 1

Which of the following best describes the main function of the seminiferous tubules in the male reproductive system?

Accepted Answer

They are the site of sperm production through spermatogenesis.

Question 2

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

Accepted Answer

Prophase I

Question 3

A patient presents with an enlarged prostate that compresses the urethra, causing difficulty urinating. Which condition is most likely responsible?

Accepted Answer

Benign Prostatic Hyperplasia (BPH)

Question 4

Which hormone is primarily responsible for triggering ovulation in the ovarian cycle?

Accepted Answer

Luteinizing hormone (LH)

Question 5

Which of the following is a key difference between spermatogenesis and oogenesis?

Accepted Answer

Spermatogenesis produces millions of sperm daily, while oogenesis typically produces one secondary oocyte per month.

Question 6

A woman is diagnosed with infertility due to blocked uterine tubes. Which of the following is a likely cause?

Accepted Answer

Pelvic inflammatory disease

Question 7

Which structure in the female reproductive system is responsible for producing estrogen and progesterone after ovulation?

Accepted Answer

Corpus luteum

Question 8

Which of the following best explains why the scrotum is located outside the abdominopelvic cavity?

Accepted Answer

To maintain a temperature approximately 3°C lower than core body temperature, which is optimal for sperm production

Question 9

Which of the following birth control methods works primarily by inhibiting the release of FSH and LH?

Accepted Answer

Hormonal contraceptives (e.g., birth control pills)

Question 10

A patient has a sperm count of 10 million sperm per milliliter of semen. According to clinical guidelines, this is most consistent with which diagnosis?

Accepted Answer

Male infertility

Question 11

Which of the following sexually transmitted infections is most strongly associated with an increased risk of cervical cancer?

Accepted Answer

Human papillomavirus (HPV)

Question 12

Which of the following best describes the function of the blood-testis barrier formed by sustentacular (Sertoli) cells?

Accepted Answer

It protects developing sperm from the immune system.

Question 13

Which phase of the uterine (menstrual) cycle is characterized by the shedding of the stratum functionalis?

Accepted Answer

Menstrual phase

Question 14

A patient is found to have elevated levels of prostate-specific antigen (PSA) in the blood. Which of the following is the most appropriate next step?

Accepted Answer

Perform a tissue biopsy of the prostate

Question 15

Which of the following best describes the role of the acrosome in sperm cells?

Accepted Answer

It contains enzymes that help the sperm penetrate the egg's zona pellucida.

Question 16

Which of the following events occurs if fertilization does NOT take place during the ovarian cycle?

Accepted Answer

The corpus luteum degenerates into the corpus albicans.

Question 17

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

Accepted Answer

Secretes slightly alkaline fluid with nutrients and enzymes that help activate sperm and function as anticoagulants

Question 18

Which of the following best explains why only one secondary oocyte is typically produced during oogenesis each month?

Accepted Answer

Most cytoplasm is allocated to one cell, while the other polar bodies degenerate.

Question 19

Which of the following is a primary function of the uterine (fallopian) tubes?

Accepted Answer

Serve as the site of fertilization and transport the oocyte toward the uterus

Question 20

Which of the following best describes the feedback mechanism that regulates testosterone production in males?

Accepted Answer

Negative feedback by testosterone and inhibin on the hypothalamus and anterior pituitary
