LH, FSH, And Progesterone FSH, or follicle stimulating hormone, is a hormone which is released by the pituitary gland and causes an ovary to prepare an egg. The egg is protected in a protective follicle, thus the name. At the same time, LH, or luteinizing hormone, is also released by the pituitary gland. The combination of FSH and LH create estrogen. However, when FSH peaks at the 15th day and then decreases, LH increases and at the peak of LH levels, also generally on the 15th day or halfway through the cycle, ovulation occurs. Ovulation is when the follicle breaks open and releases the egg. LH also changes the follicle and turns it into the corpus luteum, which creates progesterone. Progesterone is directly related to the creation of uterine lining, while FSH and LH only cause the creation of estrogen that helps create the lining. Progesterone averagely peaks at day 21 or near 3/4 through the cycle and creates more uterine lining when estrogen levels drop.
Three Hormones At Their Peak All three hormones (LH, FSH, and progesterone) can not be found at their highest levels at the same time. Only FSH and LH can be found peaking in the same day. Progesterone

Estrogen is made in the ovaries from the presence of both LH and FSH. Estrogen is used in near the beginning of the cycle, after menstruation, to start creating the uterine lining and the uterine cells. Uterine cells are used a part in the uterine lining and help expand the thickness of the lining. Estrogen is also used to help increase the amount of blood flow to the uterine lining. The addition of uterine cells, tissue, and blood flow create the lining. The cells are largest several days after the peak is because they keep growing after the peak, still using the estrogen. The uterine lining continues to grow using the estrogen, but the uterine cells do not use the progesterone to keep
