What is the progesterone "challenge test?"
What three things are tested?
if you still don't get a response, what do you need to evaluate? |
|
Definition

Term
Challenge test:
if prog causes period what does that mean?
if give progesterone to someone who doesn’t menstruate, but give progesterone and now has period-what does that mean?

Definition
if prog causes period: adequate estrogen has been produced; -
if give progesterone to someone who doesn’t menstruate, but give progesterone and now has period-what does that mean?TELLS YOU SHE HAD ESTROGEN PRODUCTION-
normal outflow tract, normal uterus, normal endometrium, normal uterus- probably hypothalamic pituitary function making estrogen |

|
Definition
|
|
Term
Explain the role of the thyroid in hyperprolactinemia. |
|
Definition
•Low serum thyroxine (T4) eliminates negative feedback to the hypothalamic-pituitary axis
•Thyrotropin-releasing hormones levels increase in the absence of negative feedback

•Elevated TRH stimulates release of prolactin from the pituitary gland.
•Reduced dopamine secretion results in elevated levels of TSH and prolactin
