Question
Differentiate between major structural changes in the human ovary during the follicular and luteal phase of the menstrual cycle.
✓
Answer
| S. No. | Follicular phase | Luteal phase |
| (i) | During this, primary follicles grow to become fully mature Graafian follicle. |
During this, remaining part of Graafian follicle transforms into corpus luteum.
|
| (ii) | Endometrium regenerates through proliferation. | Endometrium further thickens secreting progesterone for implantation after fertilisation. If fertilisation does not occur, corpus luteum degenerates. |
