Which hormone helps in the development of the female reproductive organs?

Correct Answer: A

Rationale: Estrogen is the correct answer as it is the primary hormone responsible for the development of female reproductive organs like the ovaries, uterus, and breasts. Estrogen plays a crucial role in regulating the menstrual cycle and supporting pregnancy. Testosterone is a male sex hormone. Progesterone is important for maintaining pregnancy and regulating the menstrual cycle. FSH (Follicle-stimulating hormone) stimulates the growth of ovarian follicles but is not directly involved in the development of female reproductive organs.

Correct Answer: C

Rationale: The correct answer is C: Provide sexual pleasure. The clitoris is a highly sensitive organ with numerous nerve endings, making it a key structure for sexual arousal and pleasure in females. Stimulation of the clitoris can lead to sexual satisfaction and orgasm. Choices A, B, and D are incorrect because the clitoris does not provide support for the uterus, facilitate sperm entry, or support the vaginal walls. It is important to differentiate between the functions of different reproductive organs to understand their roles in the body.

Correct Answer: B

Rationale: The correct answer is B: Passage for sperm into the uterus. Rationale: 1. The vagina serves as a pathway for sperm to travel from the male reproductive system into the female reproductive system. 2. Sperm must travel through the vagina to reach the cervix, uterus, and fallopian tubes for fertilization to occur. 3. The vagina also provides a passageway for the delivery of the baby during childbirth. Summary: A: Production of eggs - Incorrect. Eggs are produced in the ovaries, not the vagina. C: Secretion of estrogen - Incorrect. Estrogen is produced by the ovaries and plays a role in the menstrual cycle, not in the vagina. D: Site of fertilization - Incorrect. Fertilization typically occurs in the fallopian tubes, not the vagina.

Correct Answer: B

Rationale: The correct answer is B: Leydig cells secrete testosterone. These specialized cells are located in the testes and are responsible for producing and releasing testosterone, the primary male sex hormone. Testosterone plays a crucial role in the development of male reproductive organs, sperm production, sex drive, and secondary sexual characteristics. Choice A is incorrect because sperm production is primarily carried out by the Sertoli cells. Choice C is incorrect as Leydig cells do not store sperm. Choice D is incorrect as sperm transport is mainly facilitated by the vas deferens and other structures in the male reproductive system.

Correct Answer: C

Rationale: The primary role of FSH in females is to stimulate follicle development. FSH promotes the growth and maturation of ovarian follicles, which contain the eggs. This process is essential for ovulation and the release of a mature egg for potential fertilization. Choice A, stimulating ovulation, is incorrect because FSH itself does not directly trigger ovulation. Choice B, supporting the development of the corpus luteum, is incorrect because it is primarily regulated by LH, not FSH. Choice D, preparing the uterus for pregnancy, is incorrect because FSH primarily acts on the ovaries, not the uterus.
