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.
