- The Assertion is true because during each menstrual cycle, typically only one ovum is released from the ovary.
- The Reason is false; while ovarian hormones do influence the cyclical changes, pituitary hormones (like LH and FSH) are also crucial in regulating the ovarian cycle.
- Therefore, the Reason does not explain the Assertion correctly, as it overlooks the role of pituitary hormones in oogenesis and the menstrual cycle.

Assertion (A): Oogenesis results in the formation of a single ovum dur...
Assertion Explanation
Oogenesis is the process of egg (ovum) formation in females, and it typically results in the development of a single mature ovum during each menstrual cycle. This is due to the fact that among the several primary oocytes that develop, usually only one reaches maturity and is released during ovulation.
Reason Explanation
While it is true that ovarian hormones such as estrogen and progesterone play a significant role in the menstrual cycle, pituitary hormones, specifically follicle-stimulating hormone (FSH) and luteinizing hormone (LH), are also crucial. FSH stimulates the growth of ovarian follicles, and LH triggers ovulation. Therefore, the assertion that cyclical changes in the ovaries are solely influenced by ovarian hormones is incorrect.
Conclusion
Given that:
- The assertion (A) is true: Oogenesis results in the formation of a single ovum during each menstrual cycle.
- The reason (R) is false: The cyclical changes in the ovaries are influenced by both ovarian and pituitary hormones.
The correct answer is option 'C': If Assertion is true but Reason is false.
This clearly indicates that the statement regarding the sole influence of ovarian hormones on ovarian changes is not accurate, making the assertion valid while the reason is not.
