HCG is the rare item in a research catalogue that needs no introduction to medicine: it has been an approved, prescribed hormone therapy for decades, with a clinical record most compounds never approach.<\/p>\n
Human chorionic gonadotropin is a natural glycoprotein hormone. Structurally it is a close mimic of luteinising hormone (LH), the pituitary signal that tells the testes to make testosterone and the ovaries to release an egg. That mimicry is the entire clinical story: give HCG, and the body’s own hormonal machinery responds.<\/p>\n
HCG has been used clinically since the mid-twentieth century: in fertility medicine to trigger ovulation, and in men to stimulate natural testosterone and sperm production. A 2021 review in Expert Review of Endocrinology & Metabolism summarised the comparison with testosterone replacement therapy directly: testosterone replacement suppresses the body’s own production and impairs fertility, while HCG stimulates both. That is why the authors describe it as a prime candidate for secondary hypogonadism.<\/p>\n
HCG is a peptide-class molecule \u2014 a glycoprotein built from amino-acid chains \u2014 and it is studied alongside the hormonal axis compounds in this catalogue: the same research territory as tesamorelin and the growth-hormone secretagogues, one axis over.<\/p>\n
Yes. HCG has been an approved medication for decades, used clinically in fertility treatment and hormone therapy.<\/p>\n
Clinical reviews note that testosterone replacement suppresses natural production and fertility, while HCG stimulates the body’s own testosterone and sperm production.<\/p>\n
