Its structure and function are similar to those of human growth hormone.It modifies the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus. The placenta also makes a bit of HCG, as well as another hormone called human placental lactogen or hPL which counters the effect of maternal insulin to help ensure that there's plenty of glucose available in the blood for the fetus. Human placental lactogen (hPL), also previously known as "human chorionic somatomammotropin", is a 22 kD protein with partial homology to growth hormone.

Produced by syncytiotrophoblast GH is a 191-amino acid protein that is similar to prolactin (PRL) and human placental lactogen (hPL); accordingly, there is some overlap in activity among these hormones. 7. This tumour, exceptionally malignant, should be differentiated from the exaggerated placental site and its variants. A trophoblastic implantation site tumor, clearly less frequent, results from a proliferation of extravillous trophoblasts, particular for their secretion of human placental lactogen hormone (hPL). is a fetomaternal organ that enables the selective transfer of nutrients and gases between mother and fetus.
