Who Discovered HCG and How Was It First Identified?
Published 2026-07-11 · REVIVE Peptides Research Desk · 2 min read
Short answer: HCG was first identified in the early twentieth century by researchers studying substances in the urine of pregnant women that could trigger ovulation-like changes in animal ovarian tissue, work that eventually led to the earliest hormone-based pregnancy tests. Over the following decades, scientists isolated and characterized the hormone structure, which paved the way for both diagnostic testing and its later use in fertility medicine.
Early endocrinologists noticed that injecting urine from pregnant women into test animals produced reproducible ovarian responses, and this observation was the starting point for identifying HCG as the responsible substance. That early bioassay-based approach was, in effect, the ancestor of every pregnancy test used today, though the methods have since become far more precise and no longer rely on live-animal testing.
As biochemistry advanced through the mid-twentieth century, researchers succeeded in purifying HCG and mapping its two-subunit glycoprotein structure, which clarified why it behaved similarly to luteinizing hormone. This structural understanding, documented extensively across decades of published endocrinology literature, is what eventually allowed the hormone to be manufactured pharmaceutically and used clinically under regulatory oversight.
This history is provided as general background and is not connected to any product REVIVE LAB UAE offers. REVIVE LAB UAE does not sell HCG; our focus is a separate category of research peptides used in laboratory research settings.
