The graphics show us that in the first 20 years of life the person segregates more than 2000 of growth hormone and then after 25 years the amountis less, that mean that when you are Young you segregate a lot of hormone because you need to grow and then if you have 20 (aprox.) years the hormone stop because you arrive to your top of heightB.

After this phase the ovulation take place that iswhen the follicle matures and the LH is higher that produces the estrogen increase and in the case of FSH is the same low quantity and produces low progesterone and in the uterus the blood in the uteruswalls start to increase because the ovule needs the blood to fix to the walls of the uterus
An in the final phase called luteal phase the ovaries are degenerated to a luteal cell an the FSH levelsincrease producing high progesterone and the LH levels decrease producing low estrogen, an in the uterus all is like the ovulation phase
