So in a nutshell, menstrual hormones include: From the ovary, estrogen and progesterone; the
pituitary gland is luteinizing hormone, we call that LH; and follicle stimulating hormone, FSH.
Estradiol is the main endogenous estrogen, that means my body makes that. Progesterone is the main
progestational hormone and both hormones are produced by the ovaries and cause changes
in the uterus. And I know you're good at this now. There are 2 phases to the menstrual cycle,
the 1st half is the follicular phase and that's where estrogens are produced by the maturing
follicles. The luteal phase is the 2nd half and that's when progesterone is produced by the
corpus luteum. Thanks for watching our video today.
