placental hormones

After the baby's birth, the mother's placental hormones disappear and her blood sugars typically revert to normal.

Placental hormones, and to a lesser extent increased fat deposits during pregnancy, seem to mediate insulin resistance during pregnancy.

Since ST is a major source of placental hormones, which ensure optimal conditions for the fetus and mother, ERβ expression by ST may be involved in stimulation of placental hormonal production by estrogens.
