Female Reproductive Physiology MCQ Quiz | Reproduction

Welcome, MBBS Aspirants!

This quiz is expertly designed to test your understanding of Female Reproductive Physiology, a cornerstone of the MBBS curriculum. Spanning 25 multiple-choice questions, it covers the intricate hormonal cascades of the ovarian and uterine cycles, the processes of oogenesis, fertilization, implantation, and the physiological changes during pregnancy and lactation. Each question is crafted to challenge your knowledge and reinforce key concepts. After submitting your answers, you will receive your score, with correct and incorrect responses clearly highlighted for review. For your future study and revision, you can also download a PDF file containing all the questions along with their correct answers. Good luck!

Prophase I

Metaphase I

Prophase II

Metaphase II

4. The secretory phase of the uterine cycle is predominantly influenced by:

High levels of estrogen only

Follicle-Stimulating Hormone (FSH)

Progesterone

Luteinizing Hormone (LH)

5. Which hormone is responsible for maintaining the corpus luteum during early pregnancy?

Prolactin

Human Chorionic Gonadotropin (hCG)

Human Placental Lactogen (hPL)

Oxytocin

6. The proliferative phase of the endometrium is primarily driven by which hormone?

Estrogen

Progesterone

FSH

Testosterone

7. In the female reproductive cycle, inhibin B is primarily produced by the:

Corpus luteum

Theca cells

Anterior pituitary

Granulosa cells of developing follicles

8. Fertilization of the ovum most commonly occurs in which part of the female reproductive tract?

Ovary

Uterus

Ampulla of the fallopian tube

Cervix

9. The phenomenon of a secondary oocyte completing meiosis II occurs:

Just before ovulation

Immediately after fertilization

During implantation

At the time of birth

10. Which hormone is primarily responsible for the development of secondary sexual characteristics in females?

Progesterone

FSH

Estrogen

11. The conversion of androgens to estrogens in the ovarian follicle is catalyzed by the enzyme aromatase, which is stimulated by:

FSH

GnRH

Inhibin

12. What is the primary role of oxytocin during lactation?

Stimulation of milk synthesis

Inhibition of prolactin release

Contraction of myoepithelial cells for milk ejection

Development of mammary gland alveoli

13. The decline in which hormones leads to the sloughing of the endometrial lining (menstruation)?

FSH and LH

Estrogen and Progesterone

GnRH and hCG

Prolactin and Oxytocin

14. The ‘two-cell, two-gonadotropin’ theory describes the cooperation between:

Theca and granulosa cells

Sertoli and Leydig cells

Anterior and posterior pituitary cells

Syncytiotrophoblast and cytotrophoblast cells

15. During menopause, the levels of which hormones are typically elevated due to lack of negative feedback?

Estrogen and Progesterone

FSH and LH

Testosterone and DHEA

Prolactin and Oxytocin

16. The decidual reaction of the endometrium is essential for implantation and is primarily induced by:

FSH

The LH surge

Progesterone

hCG

17. Which of the following best describes the hormonal feedback mechanism that triggers the LH surge?

Negative feedback of progesterone on the hypothalamus

Negative feedback of low estrogen on the pituitary

Positive feedback of high, sustained estrogen levels on the hypothalamus and pituitary

Positive feedback of inhibin on the pituitary

18. The zona pellucida is a glycoprotein layer surrounding the oocyte. What is its primary function after fertilization?

To provide nutrients to the zygote

To prevent polyspermy and premature implantation

To secrete hCG

To initiate the first cleavage division

19. Prolactin secretion from the anterior pituitary is tonically inhibited by which neurotransmitter from the hypothalamus?

Serotonin

Acetylcholine

Dopamine

Norepinephrine

20. Which of the following is an action of progesterone on the female reproductive system?

Increases uterine contractility

Makes cervical mucus thin, watery, and more permeable to sperm

Stimulates proliferation of the endometrium

Increases body temperature and promotes uterine quiescence

21. The syncytiotrophoblast of the implanted blastocyst is primarily responsible for producing:

Amniotic fluid

hCG

Inhibin B

GnRH

22. The process by which a dominant follicle is selected to ovulate while other recruited follicles undergo atresia is primarily mediated by:

Increasing levels of progesterone

Intra-ovarian estrogen and falling FSH levels

A surge in inhibin A

Pulsatile release of GnRH

23. During pregnancy, high levels of estrogen and progesterone have what effect on the pituitary’s response to GnRH?

They enhance the release of FSH and LH

They have no effect on FSH and LH release

They suppress the release of FSH and LH, preventing ovulation

They selectively suppress FSH but enhance LH

24. What is the main physiological stimulus for prolactin release in a lactating woman?

High estrogen levels

The sound of a baby crying

Suckling at the breast

Low progesterone levels

25. The acrosome reaction is essential for fertilization. It involves the release of enzymes that allow the sperm to penetrate the:

Uterine wall

Corona radiata and zona pellucida

Oocyte cell membrane only

Cervical mucus
