उत्तर
| Sr. No. | Feature | Graafian Follicle | Corpus Luteum |
| 1. | Definition | It is the final, mature stage of a developing ovarian follicle that contains a secondary oocyte. | It is a temporary endocrine structure formed from the remains of the graafian follicle after ovulation. |
| 2. | Timing | It is present in the ovary before ovulation occurs during the follicular phase of the menstrual cycle. | It is formed after ovulation occurs during the luteal phase of the menstrual cycle. |
| 3. | Hormonal Secretion | It primarily secretes the hormone estrogen, which helps thicken the uterine lining. | It primarily secretes progesterone, which is essential for maintaining the pregnancy. |
| 4. | Physical Appearance | It appears as a large, fluid-filled sac containing a cavity called the antrum. | It appears as a yellowish mass of cells (due to the pigment lutein) and is a solid structure. |
| 5. | Biological Fate | Its fate is to rupture to release the egg (ovum) into the fallopian tube. | If fertilization does not occur, it degenerates into a white fibrous tissue called corpus albicans. |
