Research overview
HCG (human chorionic gonadotropin) is a hormone your body naturally makes during pregnancy — it's the hormone that home pregnancy tests detect. It's a fairly large protein made of 237 building blocks (amino acids) arranged in two connected pieces, and it's produced by cells in the placenta (Nwabuobi et al.). For medical use, it's manufactured either by purifying it from urine or by growing it in a lab using genetic engineering.
Mechanism under study
HCG acts like a stand-in for another hormone called LH (luteinizing hormone), which normally tells your ovaries or testicles to do their job. In pregnancy, it tells the ovary to keep making a hormone (progesterone) that supports the pregnancy. In men, it can trick the testicles into thinking they're getting the normal "make testosterone" signal, even when that signal has been shut off — for example, by testosterone therapy (StatPearls).
Human evidence summary
HCG is a well-established, heavily studied medicine for fertility treatments — it's the standard way to trigger ovulation in IVF, and doctors know a lab-made version (250 micrograms under the skin) works just as well as the older urine-derived version (10,000 units in the muscle) (Nwabuobi et al.). On the flip side, when it comes to weight loss, the FDA has stated clearly there's no real evidence it helps people lose more weight than they would otherwise (FDA Q&A on HCG weight-loss products).
Preclinical evidence summary
The existing profile data doesn't report specific animal studies for HCG — most of what's known comes directly from human medical and fertility research.
