Abstract :

This study was performed on 40 spontaneously aborted human fetuses aged between 13 and 40 weeks of gestation. Fetuses without any external and internal pathology or anomaly were included in this study. Fetuses were divided into seven groups based on gestational ages as follows: first group 13–16 weeks, second group 17–20 weeks, third group 21–24 weeks, fourth group 25–28 weeks, fifth group 29–32 weeks, sixth group 33–36 weeks and seventh group 37–40 weeks. The dimensions (length, width, thickness and weight) of the fetal thyroid glands were determined by vernier caliper instrument. The dimensions and ratios of the fetal thyroid gland (weight/fetal body weight) were evaluated. The dimensions of fetal thyroid glands increased with gestational age. This study gives knowledge of thyroid growth differentiation in different gestational ages.
