The organ (or rather, the cells within an organ) that primarily produces human chorionic gonadotropin (hCG) is the placenta. More specifically, the syncytiotrophoblastic cells of the placenta are responsible for hCG production during pregnancy.
| Organ/Cells | hCG Production |
|---|---|
| Syncytiotrophoblast cells of the Placenta | Primary Site |
Therefore, hCG is synthesized and secreted by these specialized placental cells to support the maintenance of pregnancy.
