Thyroid hormones are vital for fetal development and can act directly on placental tissues to modify their metabolism, differentiation and development.

Role of estrogen. The placenta has two major functions.

It gives nutrition to the fetus. The fetal portion of the placenta produces various hormones to help maintain the pregnancy and increase the amount of nutrient supply it receives. First, it produces spermatozoa, the male gametes. These steroid hormones stimulate placenta to produce Prostaglandins. This structure provides oxygen and nutrients to a growing baby. Steroid hormones and their precursors are of particular significance. A study published in 2018, Human Placentophagy: Effects of Dehydration and Steaming on Hormones, Metals and Bacteria in Placental Tissue, reported hormone content of raw and processed placenta, and found the highest concentrations of hormones in raw placental tissue.
