Which of the following statements relating to testosterone is correct?

Correct Answer: B

Rationale: The correct answer is B because testosterone levels do rise after puberty and slowly decline throughout a male's life due to aging. This is because testosterone plays a crucial role in male development during puberty and is responsible for maintaining male characteristics. The other choices are incorrect as testosterone levels do not rise and fall every month (A), are not at their highest during gestation (C), and are not at their highest just after birth (D).

Correct Answer: A

Rationale: The correct answer is A: Menopause. Menopause refers to the natural cessation of menstruation in middle-aged women, typically around the age of 45-55. It occurs due to declining levels of estrogen and progesterone hormones, leading to the end of reproductive capacity. Gestation (B) refers to pregnancy, not the cessation of menstruation. Implantation (C) is the process of a fertilized egg attaching to the uterus, not related to the end of menstruation. Uterus (D) is an organ involved in menstruation but does not specifically refer to the cessation of menstruation in middle age.

Correct Answer: B

Rationale: The correct answer is B: neonate. A neonate refers to a newborn baby within the first 28 days of life. The term is commonly used in medical contexts to describe infants right after birth. Rationale: 1. Obstetrician (Choice A): An obstetrician is a doctor who specializes in pregnancy, childbirth, and postpartum care. This term does not describe the baby itself. 2. Antenatal (Choice C): Antenatal refers to the period before birth, specifically during pregnancy. It does not describe the baby after birth. 3. Foetus (Choice D): A foetus is the term used for an unborn baby in the womb, not for a newborn baby after birth. In summary, the term "neonate" is the correct choice as it specifically refers to a newborn baby immediately after birth, while the other options do not accurately describe the baby at this stage.

Correct Answer: C

Rationale: The correct answer is C because testicular lobules are indeed made up of 2-3 convoluted seminiferous tubules where spermatogenesis occurs. This process of sperm production takes place within the seminiferous tubules, making option C the most accurate description of the testicular lobules. A is incorrect because the testicular lobules are not delineated by connective septa separated from the tunica albuginea. B is also incorrect as interstitial tissue is found between the lobules, not separating each individual lobule. D is incorrect as spermatogenesis specifically occurs within the seminiferous tubules, not at the level of the testicular lobules.

Correct Answer: D

Rationale: The correct answer is D: prostate. The prostate is an internal male reproductive organ located below the bladder. Step-by-step rationale: A - The penis is an external male genital organ. B - Seminal ducts are also known as vas deferens and are part of the male reproductive system. C - The corpus spongiosum is a spongy tissue structure found in the penis. Thus, the prostate is the only internal organ listed, making it the correct answer.
