Study Notes

Cyclic uterine changes are caused by hormonal changes during the ovarian cycle.
Estrogen stimulates growth of myometrium and endometrium.
Progesterone prepares endometrium for implantation.
Fall in hormone levels stimulates prostaglandin release, causing vasoconstriction and disrupting blood supply to endometrium.
Prostaglandin also causes uterine myometrium contraction, expelling blood and endometrium as menstrual flow.
Excessive contraction causes dysmenorrhea (pain).
Blood clotting disorder causes excessive flow.
Malnutrition causes menopause.
Corpus luteum continues to grow and produce progesterone and estrogen if fertilization and implantation occur.
Surgical removal of corpus luteum at 4 months causes abortion.
