What is Which of the following is the source of HCG in a pregnant female? and explain in detail?
Human Chorionic Gonadotropin (hCG) is produced in syncytiotrophoblasts. This so-called pregnancy hormone is a glycoprotein with biological activity similar to luteinizing hormone (LH). Both act the plasma membrane LH-hCG receptor. Although hCG is produced almost exclusively in the placenta, it also is synthesized in fetal kidney.
