In vitro adipose tissue lipolysis was investigated in pregnant and non-pregnant women. Basal and hormone-stimulated rates of lipolysis were significantly higher in the pregnant group. Human placental lactogen (HPL) was shown to be lipolytic on adipose tissue from both pregnant and non-pregnant women; the response being more marked in the pregnant group. We postulate that HPL is responsible for this increased lipolytic sensitivity in pregnancy, the result of which is the elevation in levels of plasma free fatty acids in the third trimester.
