HCG Research Profile
Human chorionic gonadotropin (hCG) is a glycoprotein hormone that acts
at the luteinizing hormone/chorionic gonadotropin (LH/CG) receptor.
Prescription hCG products have specific medical uses; those approvals
do not apply to research-grade material.

Product Information
About HCG
Human chorionic gonadotropin is naturally produced by the placenta
during pregnancy. It acts at the LH/CG receptor and can stimulate
hormone production in the gonads.
Prescription hCG products are available in urinary-derived and
recombinant forms. Their approved uses and instructions depend on
the specific product and its official labeling.
Research-grade hCG should not be represented as interchangeable
with a prescription medication such as Pregnyl, Novarel, or Ovidrel.
The product’s identity, form, and quantity should match its own label.

Research & Medical Context
What HCG Is Used to Study
Male Reproductive Pathways
Under specific prescription indications, hCG may stimulate Leydig
cells to produce testosterone and support spermatogenesis.
Use alongside testosterone replacement therapy to preserve
fertility is off-label and requires clinician oversight.
Ovulation and Fertility Care
Certain prescription hCG products are used in fertility treatment
to support final follicular maturation and ovulation. Treatment
requires monitoring by a fertility specialist.
Additional Labeled Uses
Some prescription hCG labeling includes treatment of selected cases
of prepubertal cryptorchidism when an anatomical obstruction is not
the cause. Approved uses vary by product and labeling.
Weight-Loss Claims
HCG is not approved for weight loss. FDA warns consumers against
HCG weight-loss products and notes that claims associated with
the “HCG diet” are not supported.
Evidence & Product Distinction
Prescription Uses Are Product-Specific
FDA-approved injectable hCG products have specific indications for
certain cases of female infertility and hormone treatment in males.
Recombinant hCG products may have different product-specific
indications and instructions.
Mood, energy, libido, or well-being changes are not guaranteed effects.
Any improvement in these areas may depend on the underlying condition
and response to medically supervised treatment.
A prescription product’s approval, testing, and instructions do not
transfer to research-grade or compounded material.
Safety & Regulatory Status
Important Safety Information
Reported effects can include injection-site reactions, headache,
irritability, restlessness, fatigue, fluid retention, and gynecomastia.
In women receiving fertility treatment, ovarian hyperstimulation
syndrome and multiple pregnancy are important risks. Rare serious risks
can include thromboembolism and hypersensitivity reactions.
HCG is a prescription medication for specific labeled indications.
It is not approved for weight loss. WADA prohibits chorionic
gonadotropin in male athletes.
Dosing, monitoring, and suitability depend on the indication and
specific prescription product. Research-grade material is not a
substitute for prescription hCG or clinician-directed care.
