GENERAL HISTOLOGY

Detailed explanation-1: -During the follicular phase of your menstrual cycle, around 11 to 20 eggs begin developing, but only one matures completely. Hormones in your brain and your ovaries regulate the changes in your body that make this process possible. Your pituitary gland releases follicle-stimulating hormone (FSH).

Detailed explanation-2: -Phase 2: The Luteal or Secretory Phase This phase always occurs from day 14 to day 28 of the cycle. Progesterone stimulated by LH is the dominant hormone during this phase to prepare the corpus luteum and the endometrium for possible fertilized ovum implantation.

Detailed explanation-3: -Also, as mentioned earlier, FSH is elevated during the early follicular phase and then begins to decline until ovulation. In contrast, LH is low during the early follicular phase and begins to rise by the mid-follicular phase due to the positive feedback from the rising estrogen levels.

Detailed explanation-4: -The luteal phase happens in the second part of your menstrual cycle. It begins around day 15 of a 28-day cycle and ends when you get your period. The luteal phase prepares your uterus for pregnancy by thickening your uterine lining.

Detailed explanation-5: -The follicular phase The follicular phase starts on the first day of your period and lasts for 13 to 14 days, ending in ovulation. The pituitary gland in the brain releases a hormone to stimulate the production of follicles on the surface of an ovary. Usually, only one follicle will mature into an egg.
