Description
HCG Technical Overview
Human Chorionic Gonadotropin (hCG) is a glycoprotein hormone produced primarily by placental trophoblast cells during pregnancy.
It contains alpha and beta subunits, and its biological activity is mediated through the luteinizing hormone/choriogonadotropin receptor (LHCGR).
hCG is investigated in reproductive endocrinology research involving receptor activation, steroidogenic signaling, trophoblast biology, and hormone assay development.

Frequently Asked Questions
What Is hCG?
A glycoprotein hormone associated with pregnancy and reproductive signaling.
What Does 10000 IU Mean?
It describes biological activity rather than a direct mass measurement.
Which Receptor Does hCG Activate?
LHCGR.
Does hCG Have a Single Peptide Sequence?
No. It consists of two glycosylated protein subunits.
Is hCG the Same as HMG?
No. They are different hormonal preparations with different compositions.
Research Overview
hCG is extensively studied as a reproductive hormone and a ligand of LHCGR.
LHCGR Signaling
Studies investigate cAMP-associated receptor signaling following hCG exposure.
Steroidogenesis Research
Experimental models examine LHCGR-related steroid hormone synthesis.
Trophoblast Research
Research investigates placental hCG production and regulation.
Hormone Assay Research
hCG serves as a target in immunoassays and molecular detection studies.
