Planning for baby and TSH is little

[deesha102]

Hi ,

I'm 35 Indian girl and planning for baby. we tried for 4 months but could not conceive. Doctor suggested to some tests and found that my TSH and prolactin is little high
Proloactine 46.19
TSH           4.66  (Range 0.45-4.5)
Free T3       3.04 ( range 1.4-4.4)
Free T4       1.10( Range .8-1.8)

Please suggest if i'm suffering from thyroid and if there is risk for pegnancy.

Yes, your thyroid levels are on the low side, which could prevent pregnancy.  In addition, high prolactin may suppress ovulation, which will prevent pregnancy, as well.  High prolactin may be caused by prolactinoma, which may cause a tumor to grow on the pituitary gland.  Hypothyroidism can cause high prolactin levels.

As for the thyroid, could you please check the reference range for the Free T3?  That seems like a very broad range, compared to what we normally see.  

Rule of thumb (where many/most of us feel best) is for Free T4 to be about mid range and Free T3 to be in the upper half to upper third of its range.  Your Free T4 is only at 30% of its range, so it falls somewhat short of the midway point.  Your Free T3 is at 55%, so it's still okay, but FT3, often, lags behind FT4, so it's just a matter of time before yours would drop below the recommended level.  

Adequate thyroid hormones are necessary for pregnancy to occur, plus they are necessary for the proper growth and development of a fetus, since the fetus depends on the mother's hormones until its own thyroid can produce hormones on its own. Your thyroid hormone levels should be brought to normal levels prior to attempting to get pregnant again.  Most women find that thyroid hormone levels must be kept higher than usual during pregnancy in order to provide adequate levels for both mother and fetus.
