Summary Amniotic fluid temperature in first trimester pregnancies and fetal subcutaneous tissue and amniotic fluid temperature in second trimester pregnancies, measured by a thermocouple probe, did not increase during sector, linear‐array or Doppler ultrasound scanning. The mean fetal muscle temperature was higher (36·9°C) than mean amniotic fluid temperature (36·6°C) during the second trimester.
