The prostate:
- A. is located under the urinary bladder;
- B. is located around the initial segment of the urethra;
- C. is an accessory gland of the male reproductive system;
- D. secretes androgenic hormones;
Correct Answer: C
Rationale: Step-by-step rationale:
1. The prostate is an accessory gland because it produces and secretes fluid that nourishes and protects sperm.
2. It is not located under the urinary bladder (A) but surrounds the initial segment of the urethra (B).
3. The prostate does not secrete androgenic hormones (D); instead, it secretes prostate-specific antigen (PSA) and enzymes.
4. Thus, the correct answer is C because it accurately describes the function of the prostate as an accessory gland of the male reproductive system.

If a radioimmunoassay is properly conducted and the amount of radioactive hormone bound to antibody is low, this would indicate which of the following?
- A. Plasma levels of endogenous hormone are high
- B. Plasma levels of endogenous hormone are low
- C. More antibody is needed
- D. Less radioactive hormone is needed
Correct Answer: A
Rationale: The correct answer is A: Plasma levels of endogenous hormone are high. When the amount of radioactive hormone bound to the antibody is low in a radioimmunoassay, it indicates that there is a high concentration of non-radioactive, endogenous hormone present in the sample competing for binding sites on the antibody. This competition results in fewer radioactive hormones binding to the antibody. Therefore, the low radioactive hormone binding suggests an abundance of non-radioactive hormone in the sample.
Choice B is incorrect because low levels of radioactive hormone binding do not indicate low plasma levels of endogenous hormone. Choice C is incorrect as more antibody wouldn't affect the binding of radioactive hormone if endogenous hormone levels are high. Choice D is incorrect because the amount of radioactive hormone needed is not related to the binding observed in the assay.
Which gland provides fructose, a sugar in semen that energizes sperm?
- A. Seminal vesicles
- B. Bulbourethral gland
- C. Prostate
- D. Epididymis
Correct Answer: A
Rationale: The correct answer is A: Seminal vesicles. These glands produce fructose, a sugar in semen that provides energy for sperm. Seminal vesicles are located near the base of the bladder and are responsible for producing a significant portion of the fluid in semen. The other choices are incorrect because the bulbourethral gland produces a clear lubricating fluid, the prostate produces a milky fluid that helps with sperm motility and viability, and the epididymis is a coiled tube where sperm mature and are stored, but it does not produce fructose.
Human chorionic gonadotropin (hCG) produces fluid that activates sperm.
- A. prostatic urethra
- B. ovary.
- C. prostate
- D. corpus luteum.
Correct Answer: D
Rationale: The correct answer is D: corpus luteum. Human chorionic gonadotropin (hCG) is produced by the developing placenta during pregnancy. This hormone helps maintain the corpus luteum, which in turn produces progesterone to support the pregnancy. The fluid produced by the corpus luteum helps activate sperm for fertilization. Choices A, B, and C are incorrect as they are not directly involved in the production of hCG or the activation of sperm.
Chronic cervicitis is treated with
- A. Antibiotics
- B. Antifungals
- C. Antivirals
- D. Anti-inflammatory drugs

Rationale: Antibiotics are typically used to treat chronic cervicitis caused by bacterial infections.
