The 4 Stages of the Menstrual cycle

1) Follicle Stage, Hormone (FSH) is secreted from the anterior lobe of the pituitary gland n day 5 of the cycle. An egg cell also begins to mature inside the follicle (10-day cycle)

2) Ovulation Stage, When estrogen in the Female bloodstream reaches a high and it cause the pituitary gland to stop the production of FSH and starts the production of luteinizing hormone (LH) which causes the follicle to break and releases the mature egg cell (Occurs around day 14)

3) Corpus Luteum Stage, After Ovulation LH stimulates cells of the ruptured follicle and creates Corpus Luteum which then the Corpus produces progesterone "pregnancy hormone" which thickens the endometrium to prevent the new formation of new ovarian follicles (Lasts about 14 days)

4) Menstruation Stage, fertilization does not occur which leads to LH secretion with the low LH level it produces Corpus which starts to break down progesterone the leads to the endometrium thinking the unfertilized egg and a small quantity of blood leave the female in a span of 4 days, and FSH causes a new follicle to grow (Occurs on day 28)
