GENERAL HISTOLOGY

Detailed explanation-1: -During this phase, the following events occur: The rise in estrogen from the dominant follicle triggers a surge in the amount of luteinizing hormone (LH) that your brain produces. This causes the dominant follicle to release its egg from the ovary.

Detailed explanation-2: -The follicular phase is the longest phase of your menstrual cycle. During ovulation, your ovary releases the egg that matured during the follicular phase. It begins its journey to your fallopian tubes. Ovulation marks the end of the follicular phase and the beginning of the luteal phase.

Detailed explanation-3: -The first phase of the menstrual cycle is the follicular or proliferative phase. It occurs from day one to day 14 of the menstrual cycle, based on the average duration of 28 days. The variability in the length of the menstrual cycle occurs due to variations in the length of the follicular phase.

Detailed explanation-4: -It is generally agreed in the human that a selected follicle becomes dominant about a week before ovulation; i.e., as early as days 5 to 7 of the cycle at a time when follicular diameter is around 10 mm. Only the dominant follicle can at this point in time boast detectable levels of FSH in its follicular fluid.
