[ 11 ] This figure displays the expected increasing slopes during the third trimester and a leveling off beyond 40 weeks previously seen in menstrually dated pregnancies.
And the pollsters also detected an increasingly acute sensitivity to abortion timing: Sixty-one percent of those polled thought abortions should be permitted during the first trimester, but only 15 percent in the second and just 7 percent in the third.
This resembles high LHR expression in first trimester placenta [ 28 ] , which is a source of high hCG levels [ 59 ] . Yet, hCG levels fall during the second trimester, and elevated maternal midtrimester hCG is associated with higher rates of maternal and neonatal complications (pregnancy-induced hypertension, preeclampsia, gestational diabetes, and perinatal death) [ 60 61 62 63 ] .
During the third trimester, and after 34-36 weeks of pregnancy in particular, the placenta may develop an abnormality, often classified as placental aging [ 19 20 21 22 23 24 ] . These abnormal placentae are characterized by generalized interstitial fibrosis and fibrinoid degeneration of villous stroma, and are associated with cellular apoptosis and congestion of villous sinusoids [ 24 25 26 27 ] . Immunohistochemically, villous abnormality is associated with progressive diminution of Thy-1 differentiation protein in the villous core [ 28 ] . Marked changes in villous structure are particularly associated with advanced maternal age [ 29 30 ] . We have recently reported that, with respect to the Thy-1 expression, compensatory dilatation of villous sinusoids, and placental expression of low molecular weight cyclin E variants, the term placentae can be classified into four placental types (PT1-PT4) [ 30 ] , where PT4 corresponds to the most severe placental abnormality.
