Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone composed of α and β subunits, functionally related to luteinizing hormone (LH). It is the same active molecule used in the pharmaceutical preparation “Pregnyl”. In research, HCG is studied for its role in reproductive endocrinology, gonadal activation, and hormonal feedback regulation.

Scientific Background

HCG plays a key role in signaling within the hypothalamic–pituitary–gonadal (HPG) axis. It mimics endogenous LH and is used in laboratory models to stimulate steroidogenic pathways, evaluate Leydig cell function, and explore gonadotropin receptor activity.

Product Composition

• Compound: Human Chorionic Gonadotropin (recombinant or purified form)
• Form: Lyophilized powder for laboratory reconstitution
• Content: 5000 IU per vial

Kit Contents

• 1 × 5000 IU lyophilized HCG powder vial (vacuum sealed at +1 Pa)
