3. | Ovulatory phase | 4. | Secretory phase |
1. | Menstrual → Follicular → Secretory → Ovulatory |
2. | Menstrual → Follicular → Ovulatory → Secretory |
3. | Ovulatory → Follicular → Secretory → Menstrual |
4. | Menstrual → Secretory → Follicular → Ovulatory |
Which hormone is mainly secreted by the developing follicles during the proliferative phase of the menstrual cycle?

3. | Progesterone | 4. | Estrogen |
The peak levels of LH and FSH are observed on day _____ of a typical menstrual cycle.
1. | 6 | 2. | 14 |
3. | 22 | 4. | 28 |
Assertion (A): | In a female with 29 days menstrual cycle, ovulation occurs on day fourteen. |

Corpus luteum is:

3. Developing follicle
4. Enzyme-secreting structure in the ovary
Corpus luteum secretes large amounts of:

3. | Progesterone | 4. | Estrogen |
Statement I: | A is also called as secretory phase and is the phase of the menstrual cycle where the follicle matures into a Graafian follicle. |
Statement II: | B is the luteal phase and is the phase when the uterine endometrium regenerates through proliferation. |
