  1. Women who are already on T4 treatment prior to pregnancy usually need to increase their replacement dose by?
    30 percent to 50 percent during pregnancy.
  2. They also need to recheck their TSH every four weeks until it is normalized,
    and then every six to eight weeks after that.
  3. The goal for pregnant women is to maintain a TSH level of at least _________ in the 1st trimester
    2.3 mIU/L
  4. Infertility is considered to be a risk factor for ?
    thyroid dysfunction.
  5. Checking TSH levels with a second hCG pregnancy test may be beneficial for detecting early
    thyroid dysfunction.
  6. A TSH level greater than 2.5-3 mIU/L during early pregnancy may indicate subclinical hypothyroidism and treatment may be warranted.
  7. This is because pregnancy unmasks an incipient, hypothyroid state that would eventually become clinically evident.
  8. Thyroid antibody testing may also be useful in determining if the woman is at risk for developing
    hypothyroidism in the future.
  9. Because the fetus relies on maternal thyroid hormone and iodine is necessary for the production of thyroid hormones,it is important that pregnant women have adequate ?
    iodine in their prenatal vitamin
  10. Iodine is recommended at what dosage?
    150-250 mcg in the form of potassium iodide
  11. This dose is especially important for women who use ?
    • sea salt (noniodized)
    • vegan
    • low-sodium
    • dairy-free diets,
  12. Abnormal thyroid function can alter levels of ?
    • sex hormonebinding globulin (SHBG)
    • prolactin
    • gonadotropin releasing hormone (GnRH)
  13. Abnormal thyroid function can lead to ?
    menstrual dysfunction
  14. One of the beneficial effects of T4 treatment for hypothyroidism is the ?
    restoration of regular menstrual cycle.
  15. The presence of thyroid antibodies is also associated with increased risk of?
  16. Many studies propose the upper limit of normal TSH for fertility patients as ?
    2.5 mIU/L, but further research is needed.
  17. Increased estrogen from ovarian stimulation or pregnancy may place too high a strain on the thyroid gland in women who already have thyroid autoimmunity.
  18. Women with positive thyroid antibodies but normal TSH levels may benefit from treatment to ?
    stop or slow the progression to hypothyroidism
  19. Studies report an increase in prevalence of autoimmune thyroid disease in ?
    infertile women
  20. Screening infertility patients could help detect and prevent an evolution to overt thyroid dysfunction after ovarian stimulation in women with ?
    autoimmune disease
  21. Treatment with T4 is recommended when subclinical hypothyroidism is present in women with ?
    • infertility
    • irregular menses
    • after ovarian stimulation
  22. TSH and free T4 are useful, initial laboratory markers for determining ?
    thyroid function
  23. Common disorders among women of reproductive age include ?
    hypothyroidism & hyperthyroidism.
  24. The presence of thyroid antibodies is associated with a risk of?
  25. Screening for thyroid dysfunction and autoimmunity should be considered as part of the ?
    general work‑up in women facing infertility issues.
