hCG

Also known as: Human Chorionic Gonadotropin, Chorionic Gonadotropin, Pregnyl, Novarel, Ovidrel

FDA approved

Human chorionic gonadotropin is a placental glycoprotein hormone composed of a 92-amino-acid alpha subunit (shared with LH, FSH, and TSH) and a distinct 145-amino-acid beta subunit, joined non-covalently and heavily glycosylated. It acts as an agonist at the luteinizing hormone/choriogonadotropin receptor (LHCGR), mimicking the LH surge. In females it sustains the corpus luteum and progesterone production in early pregnancy and triggers final oocyte maturation and ovulation; in males it stimulates testicular Leydig cells to produce intratesticular testosterone, supporting spermatogenesis. hCG is FDA-approved (e.g., Pregnyl, Novarel, recombinant Ovidrel) for ovulation induction, assisted reproduction, and male hypogonadism/cryptorchidism.

Typical dose range

Fertility (final oocyte maturation): single 5,000-10,000 IU intramuscular or subcutaneous. Male TRT adjunct: commonly 250-500 IU subcutaneous 2-3x weekly (protocols vary, up to ~1,500 IU)

Half-life

~24-36 hours terminal half-life after IM/SC injection (biphasic; longer than LH due to glycosylation)

Common research uses

ovulation induction in assisted reproduction (IVF/IUI)male hypogonadism and restoring/maintaining fertility during testosterone replacement therapyprevention of testicular atrophy on TRTtreatment of cryptorchidism in boys

Safety notes

FDA-approved prescription drug; prescription-only in the US. Risks include ovarian hyperstimulation syndrome (OHSS) in women, thromboembolism, gynecomastia and fluid retention in men, and injection-site reactions. hCG is prohibited in men at all times under the WADA Code (S2 peptide hormones); homeopathic/weight-loss hCG products are not FDA-approved and are considered illegal/fraudulent.

Reconstitution

Lyophilized urinary hCG is reconstituted with the supplied bacteriostatic diluent; refrigerate after reconstitution and use within the labeled window. Recombinant hCG (Ovidrel) is supplied prefilled.

Relationship Between Dominant Follicle Diameter on the hCG Trigger Day and Live Birth After Modified Natural Cycle Frozen Embryo Transfer: A Retrospective Cohort Study

Background The impact of dominant follicular diameter at hCG trigger on live birth rate (LBR) in modified natural cycle frozen-thawed embryo transfer (mNC-FET) remains unclear. This study aimed to evaluate this relationship and explore whether flexible triggering based on follicle size is acceptable.

Optimization of Pregnancy Testing in the Emergency Department: A Quality Improvement Initiative

Background At our institution, a review of emergency department pregnancy testing identified excess use of serum quantitative (quant) human chorionic gonadotropin (hCG) when only a binary result was clinically indicated. Additionally, we observed delays in point-of-care (POCT) urine hCG turnaround time.
