Does maternal high TSH level cause breech presentation at term?

Abstract

Breech presentation is the most common abnormal fetal presentation and generally associated with maternal and neonatal morbidity and mortality. Recently, high thyroid stimulating hormone (TSH) levels were claimed to cause breech presentation at term. The aim of this study was to evaluate the effect TSH on breech presentation. A total of 60 patients who had delivery after 37 gestational weeks at Fatih University School of Medicine Department of Obstetrics and Gynecology and whose TSH levels were available were included in the study. 30 of 60 patients had breech presentation and 30 had cephalic presentation at delivery. Statistical analysis between TSH and breech presentation was performed by using the Statistical Package of Social Science and Problems Solutions Version 16.0 (SPSS). TSH levels were 1.88 mIU/l and 1.51 mIU/l in group A and group B, respectively. The groups were not statistically different (p=0.1). Additionally, patients were divided into 2 groups according to TSH levels (<2.5 mU/l or ≥2.5 mU/l), however the groups were also not different with regard to presentation. No relation between TSH levels and breech presentation was determined in the present study.
