Thyroid Function Before and After Induced Abortion in Normal Pregnant Women

Abstract

We assessed thyroid function before and after induced abortion in 25 normal pregnant women. Serum TSH was significantly increased (P<0.02), and serum hCG-β was significantly reduced (P<0.001) 1 week after induced abortion, compared with the levels before induced abortion. There was a significant negative correlation between hCG-β and TSH, and a positive one between hCG-β and FT4 before induced abortion (P<0.02). No difference was observed in thyroid hormones before and 1 week after induced abortion. The results suggest that hCG stimulates the thyroid gland, gaining an advantage over TSH, in normal pregnant women.
