Question

Rupturing of follicles and discharge of ova is known as
A. Copulation
B. Conjugation
C. Ovulation
D. None of the above

Answer 1

Hint: Rupturing of the Graffian follicles causes the release of ova or mature oocyte from the ovary. This event takes place around 12-16 day of the menstrual cycle.

Complete Answer:
Let us analyse the options to find the correct answer.
Option A: Copulation is the sexual intercourse that takes place between a male and female where the male sperm is introduced in the female body. Hence, this is an incorrect option.
Option B: Conjugation is a process in which a donor bacteria transfers its genetic material to a recipient bacteria by direct contact. Hence, this is an incorrect option.
Option C: Ovulation is the discharge of ova or an egg from the ovary. It is caused by the rupturing of follicles. It only lasts for one day and takes place approximately around the 14th day of the menstrual cycle. The time of ovulation usually depends on the length of a woman’s menstrual cycle. Hence, this is the correct option.

Additional Information:
- The maturing follicle in the ovary leads to rise in estrogen levels.
- Rising estrogen levels cause LH surge around the 12th day and lasts for at least 2 days or so.
- The rise in LH levels causes the wall of the follicles to weaken leading to the release of secondary oocytes from the mature follicle.
- Ovulation is followed by the Luteal phase.

Hence the correct answer is option C.

Note: The second phase of menstrual cycle is called ovulation. After the release of the egg from the ovary it travels down to the fallopian tube where it may get fertilized by the sperm.
