After Sam fathers five children, he and his wife decide that he should have a vasectomy, which is a cutting and removal of a small section of each vas deferens. Why will this cause Sam to be infertile?
- A. It will become impossible for him to ejaculate during coitus.
- B. The sperm will not be able to get from the epididymis to the urethra.
- C. He will no longer produce sperm.
- D. The seminal fluid will be too acidic for the sperm to survive.
Correct Answer: B
Rationale: Step 1: Vasectomy involves cutting and removing a small section of each vas deferens, the tubes that carry sperm from the testicles to the urethra.
Step 2: By severing the vas deferens, sperm are physically blocked from reaching the urethra.
Step 3: Without the ability for sperm to travel through the vas deferens to the urethra, they cannot be ejaculated during coitus.
Step 4: Therefore, choice B is correct - the sperm will not be able to get from the epididymis to the urethra, causing infertility.
Summary:
Choice A is incorrect because ejaculation is the release of semen, not sperm. Choice C is incorrect as the testicles continue to produce sperm, but the sperm cannot reach the urethra. Choice D is incorrect as the acidity of seminal fluid does not affect the ability of sperm to travel through the vas deferens.
