Question 24 Which condition refers to painful urination in males?

Dysuria

Hematuria

Oliguria

Polyuria

Question 25 The medical term “oligospermia” describes:

No sperm production

Low sperm count

Low semen volume

Abnormal sperm shape

Question 26 Which structure prevents backflow of semen into the bladder during ejaculation?

External urethral sphincter

Internal urethral sphincter

Prostate gland

Bulbourethral gland

Question 27 The penis contains erectile tissue called:

Seminiferous tissue

Spongy tissue

Corpus cavernosum and corpus spongiosum

Connective tissue only

Question 28 Which anatomical feature allows erection to occur?

Muscle contraction only

Increased arterial blood flow into erectile tissue

Increased urine flow

Hormone release only

Question 29 Which term refers to inflammation of the prostate gland?

Orchitis

Prostatitis

Epididymitis

Cystitis

Question 30 Why must the testes be located outside the abdominal cavity?

To protect sperm from infection

To allow sperm storage

To maintain a temperature lower than core body temperature

To increase hormone secretion

Đáp án chi tiết:

Explanation: Spermatogenesis requires a temperature slightly lower than core body temperature, which is achieved by the scrotum

Question 31 Damage to Sertoli cells would most directly affect:

Testosterone production

Sperm nourishment and maturation

Semen ejaculation

Erectile function

Đáp án chi tiết:

Explanation: Sertoli cells support, nourish, and regulate developing sperm cells.

Question 32 Why is fructose important in seminal fluid?

It neutralizes acidity

It activates sperm DNA

It provides energy for sperm motility

It increases semen volume only

Đáp án chi tiết:

Explanation: Fructose serves as an energy source for sperm movement

Question 33 Obstruction of the vas deferens would most likely cause:

Reduced testosterone levels

Impaired sperm transport

Erectile dysfunction

Prostate inflammation

Đáp án chi tiết:

Explanation: The vas deferens transports sperm from the epididymis to the ejaculatory duct.

Question 34 Why does inflammation of the prostate often cause urinary symptoms?

It affects kidney filtration

It compresses the urethra

It reduces sperm production

It blocks the ureters

Đáp án chi tiết:

Explanation: The prostate surrounds the urethra; inflammation can narrow the urethral lumen.

Question 35 Which mechanism prevents urine from mixing with semen during ejaculation?

Closure of the external urethral sphincter

Relaxation of the bladder

Contraction of the internal urethral sphincter

Reduced kidney output

Đáp án chi tiết:

Explanation: The internal urethral sphincter closes the bladder neck during ejaculation

Question 36 Why does hypogonadism result in infertility?

Reduced semen volume only

Lack of erectile tissue

Insufficient testosterone affecting spermatogenesis

Blockage of the urethra

Đáp án chi tiết:

Explanation: Testosterone is essential for normal sperm production.

Question 37 Which condition increases the risk of testicular damage due to heat?

Hydrocele

Varicocele

Prostatitis

Phimosis

Đáp án chi tiết:

Explanation: Varicocele impairs venous drainage, increasing testicular temperature.

Question 38 Why is the epididymis essential for fertility?

It produces sperm

It stores hormones

It allows sperm to mature and gain motility

It neutralizes acidity

Đáp án chi tiết:

Explanation: Sperm leaving the testes are immature and require epididymal maturation

Question 39 Which finding most strongly suggests obstruction rather than production failure?

Low testosterone

Absent sperm with normal hormone levels

Testicular atrophy

Delayed puberty

Đáp án chi tiết:

Explanation: Normal hormones with azoospermia suggest blockage of sperm transport.

Question 40 The main purpose of studying male reproductive terminology is to:

Replace laboratory tests

Memorize anatomy only

Accurately describe structure, function, and pathology

Avoid clinical examination

Đáp án chi tiết:

Explanation: Proper terminology ensures clear communication and accurate diagnosis in clinical practice
