The primary sex organ in the male is the _____.
- A. penis
- B. testis
- C. scrotum
- D. epididymis
Correct Answer: B
Rationale: The correct answer is B: testis. The testis is the primary male sex organ responsible for producing sperm and testosterone. It is located within the scrotum. The penis (choice A) is the male reproductive organ used for sexual intercourse but is not the primary sex organ. The scrotum (choice C) is the external sac that houses the testes but is not the primary sex organ itself. The epididymis (choice D) is a coiled tube located on the testis where sperm mature and are stored, but it is not the primary sex organ.

With respect to ejaculation which of the following statements is incorrect.
- A. ejaculation is the result of para-sympathetic stimulation
- B. ejaculation results from the summation of synaptic potentials
- C. during ejaculation semen is expelled by rapid contraction of the urethral smooth muscle
- D. ejaculation results is the discharge of sperm, seminal vesicle and prostatic secretions
Correct Answer: A
Rationale: The correct answer is A because ejaculation is primarily controlled by the sympathetic nervous system, not the para-sympathetic system. The sympathetic nervous system triggers the contraction of smooth muscles to allow for ejaculation. Choice B is incorrect because ejaculation is not a result of summation of synaptic potentials, but rather a coordinated response. Choice C is incorrect because semen is expelled by rhythmic contractions of the pelvic floor muscles, not the urethral smooth muscle. Choice D is incorrect because ejaculation involves the discharge of sperm, seminal vesicle, prostatic secretions, and other fluids from the reproductive system.
Which questions are appropriate for a symptom analysis of a patient with benign prostatic hyperplasia?
- A. How often have you found that you stopped and started again several times when you urinated?
- B. How often have you had to urinate again less than 2 hours after you finished urinating?
- C. How often have you been incontinent of urine?
- D. How often have you had constipation due to the enlarged prostate?
Correct Answer: B
Rationale: The correct answer is B because frequent urination less than 2 hours after finishing can be indicative of benign prostatic hyperplasia (BPH). This symptom, known as urgency, is common in patients with BPH due to bladder irritation. Option A relates more to urinary flow patterns, not specifically associated with BPH. Option C pertains to urinary incontinence, which is not typically a symptom of BPH. Option D is not directly related to BPH symptoms, as constipation is not a common manifestation of this condition.
Regarding gross anatomy of male reproductive system
- A. Dartos muscle is responsible to raise and lower the testes
- B. Ductus deferens penetrate the prostate gland to connect with prostatic urethra
- C. Anterior lobe of prostate gland is the main glandular tissue
- D. Buck's fascia encloses body of penis
Correct Answer: B
Rationale: The correct answer is B because the ductus deferens penetrates the prostate gland to connect with the prostatic urethra, forming the ejaculatory duct. This allows for the transport of sperm from the epididymis to the urethra during ejaculation.
A: Dartos muscle is responsible for wrinkling the scrotal skin but not raising and lowering the testes.
C: The anterior lobe of the prostate gland mainly consists of fibromuscular tissue, not glandular tissue.
D: Buck's fascia surrounds the corpora cavernosa and the corpus spongiosum of the penis, not the body of the penis itself.
Female infertility can be caused by hormonal problems, blocked fallopian tubes, and
- A. a cold
- B. lack of appetite
- C. irregular menstrual cycles
- D. STDs
Correct Answer: D
Rationale: The correct answer is D: STDs. Sexually transmitted diseases (STDs) can lead to pelvic inflammatory disease (PID) which can cause scarring and blockage of the fallopian tubes, leading to female infertility. STDs such as chlamydia and gonorrhea can also cause damage to the reproductive organs, affecting fertility. Therefore, STDs are a significant factor contributing to female infertility.
A: A cold is a common viral infection that does not directly impact female fertility.
B: Lack of appetite is not a known cause of female infertility.
C: Irregular menstrual cycles can be a symptom of hormonal imbalances but may not directly lead to infertility.
The male reproductive system is made up of the following structures, EXCEPT:
- A. prostate;
- B. testicle;
- C. spermatic ducts;
- D. vestibular bulbs;
Correct Answer: D
Rationale: The correct answer is D: vestibular bulbs. The male reproductive system consists of the prostate, testicles, and spermatic ducts, all essential for the production, storage, and transportation of sperm. Vestibular bulbs are actually part of the female reproductive system, involved in sexual arousal, and not found in the male reproductive system. Therefore, it is the only structure listed that is not a part of the male reproductive system.
