Options:

Secretory phase .

Follicular phase .

Luteal phase .

None of these .

Correct Answer:

Follicular phase .

Explanation:

The correct answer is Option (2) → Follicular phase .


Menstrual phase : This phase takes place from the 1st to the 5th day, where the shedding of the uterine lining occurs, resulting in menstrual bleeding.

Proliferative phase: This phase occurs from the 5th to the 13th day of the cycle.The menstrual phase is followed by the follicular phase. During this phase, the primary follicles in the ovary grow to become a fully mature Graafian follicle and simultaneously the endometrium of uterus regenerates through proliferation.

Ovulatory phase: This occurs around the 14th day of the cycle, when the mature egg is released from the ovary, ready for fertilization.

Secretory phase : This phase occurs from the 15th to the 28th/29th day, after ovulation, where the endometrium becomes more glandular and prepares for potential implantation of a fertilized egg.
