When do the testes begin to descend?
- A. at birth
- B. two months after birth
- C. two months prior to birth
- D. in the fifth month of pregnancy
Correct Answer: D
Rationale: The correct answer is D: in the fifth month of pregnancy. The testes begin to descend from the abdomen into the scrotum during the fifth month of pregnancy. This process is crucial for proper development and function of the testes. Descending at this stage allows for the testes to be positioned outside the body, which is essential for sperm production as it requires a slightly lower temperature than the internal body temperature.
Summary:
A: at birth - Incorrect, as the descent of the testes occurs during fetal development, not at birth.
B: two months after birth - Incorrect, as the descent happens during pregnancy, not after birth.
C: two months prior to birth - Incorrect, as the descent occurs during pregnancy, not prior to birth.

- B. Antiviral IV drugs are recommended to prevent viral shedding.
- C. Topical applications of the antiviral drugs are recommended for clinical benefits.
- D. Use of alcohol, peroxide, witch hazel, and warm air from a hair dryer are recommended to keep the lesions dry.

Rationale: Notifying and treating all sexual contacts is essential to prevent further spread of genital warts.
Which one of the following is NOT a (vas) deferens, epididymis, component of semen?
- A. sperm
- B. epididymis, seminal glands
- C. seminal fluid
- D. prostatic fluid
Correct Answer: A
Rationale: The correct answer is A: sperm. Sperm is not a component of semen; it is the male reproductive cell. Semen is composed of fluids from the epididymis, seminal glands, and prostate, which provide nourishment, protection, and transportation for sperm. The epididymis stores and matures sperm, seminal glands produce seminal fluid, and the prostate contributes prostatic fluid. Sperm is only a part of semen and not a component of it. Therefore, choice A is the correct answer.
When sexual feelings occur, it is important to
- A. consciously choose to act responsibly
- B. go to a quiet place and talk about what you are feeling with your partner
- C. explore the feelings and do what feels best
- D. see a doctor
Correct Answer: A
Rationale: The correct answer is A because it emphasizes the importance of consciously choosing to act responsibly when sexual feelings arise. This involves considering the consequences, respecting boundaries, and making informed decisions. Going to a quiet place to talk (B) may not address responsible actions. Exploring feelings and doing what feels best (C) may lead to impulsive or harmful choices. Seeing a doctor (D) is not necessary for regular sexual feelings. A conscious and responsible approach promotes healthy relationships and personal well-being.
Which situation would be part of the normal reproductive cycle of a human?
- A. the presence of testosterone regulating gamete production in a male
- B. estrogen in concentrations that would produce sperm in a female
- C. a high progesterone level in a male
- D. a low insulin level in either a male or a female
Correct Answer: A
Rationale: Step 1: Testosterone is a hormone primarily produced by the testes in males, regulating sperm production.
Step 2: Gametes are reproductive cells (sperm in males), crucial for the reproductive cycle.
Step 3: Therefore, the presence of testosterone regulating gamete production in a male is a normal part of the reproductive cycle.
Summary:
- Option B is incorrect as estrogen, a female sex hormone, does not produce sperm.
- Option C is incorrect as progesterone is a hormone mainly involved in the menstrual cycle and pregnancy, not in males.
- Option D is incorrect as insulin is a hormone related to glucose metabolism, not directly involved in the reproductive cycle.
About the Fallopian tubes we can state the following:
- A. are funnel-shaped, with edges flared towards the uterus;
- B. the medial extremity displays flares;
- C. it is linked to the uterus through the uterine ostium;
- D. the lateral extremity opens in the abdominal cavity;
Correct Answer: A
Rationale: The correct answer is A because Fallopian tubes are indeed funnel-shaped, with edges flared towards the uterus. This shape helps capture the released egg from the ovary and guide it towards the uterus for potential fertilization. The other choices are incorrect because the medial extremity does not display flares (B), the Fallopian tube is not directly linked to the uterus through the uterine ostium (C), and the lateral extremity does not open in the abdominal cavity (D). Therefore, choice A is the most accurate description of the Fallopian tubes based on their anatomy and function.
