The ovary connects by ligaments to:

Correct Answer: A

Rationale: The correct answer is A: the uterus. The ovary connects to the uterus via ligaments called ovarian ligaments. This connection is essential for the transfer of eggs from the ovary to the uterus during the menstrual cycle and for providing support to the ovary. The other choices are incorrect as the ovary does not directly connect to the Fallopian tubes (B), rectum (C), or pelvic walls (D) via ligaments. The connection to the uterus is crucial for reproductive functions and maintaining the structural integrity of the female reproductive system.

Correct Answer: C

Rationale: Step-by-step rationale: 1. The mammary gland is not an erectile organ, eliminating choice A. 2. It is not part of the internal genital organs, ruling out choice B. 3. The mammary gland is indeed an accessory gland of the female reproductive system, making choice C correct. 4. Lastly, the mammary gland is a pair of organs, which supports choice D as incorrect. Therefore, choice C is correct as the mammary gland functions as an accessory gland in the female reproductive system.

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.
