hCG 5000iu Injection (Human Chorionic Gonadotropin)

Product Overview

hCG 5000IU Injection is a sterile, lyophilized preparation of Human Chorionic Gonadotropin intended for parenteral use. Each vial contains 1 ml of solution delivering 5000 International Units of the hormone. The product is supplied by Sanzyme Biologics (P) Ltd, a manufacturer approved under Indian regulatory standards for biologics. Packaging options include 5, 10, or 20 injections per carton, allowing clinics and patients to select the most appropriate supply size for their treatment course.

What is hCG 5000IU Injection

Human Chorionic Gonadotropin (hCG) is a glycoprotein hormone produced by the placenta after implantation. Clinically, synthetic hCG is indistinguishable from the native hormone and interacts with luteinizing hormone receptors in target tissues. The 5000IU strength is the dosage most frequently employed in assisted reproductive technology (ART) and in endocrine therapy for men. Because the molecule is identical to the natural surge that triggers ovulation or stimulates testosterone production.

The medication is indicated for two primary therapeutic areas: female infertility, where it is used to induce final follicular maturation and ovulation, and male hypogonadism, where it supports the restoration of endogenous testosterone synthesis. The drug is delivered via intramuscular or subcutaneous injection, and the choice of route is determined by the prescribing clinician based on patient tolerance and treatment protocol.

Uses and Benefits

In female patients undergoing in‑vitro fertilization (IVF) or other ART procedures, a single dose of hCG 5000IU is typically administered to trigger the final maturation of oocytes before retrieval. This timing is critical for maximizing egg quality and retrieval yield. Additionally, hCG can be used in luteal phase support to maintain progesterone production, thereby improving implantation rates.

For male patients with hypogonadotropic hypogonadism, hCG therapy can stimulate Leydig cells to produce testosterone, which may alleviate symptoms such as reduced libido, fatigue, loss of muscle mass, and decreased bone density. When combined with lifestyle modifications or other hormonal agents, hCG can contribute to a more physiological hormonal environment.

Beyond reproductive applications, hCG is occasionally employed in research settings to modulate immune responses or as a biomarker in certain diagnostic algorithms. Its well‑characterized pharmacodynamics and established safety profile make it a reliable tool for clinicians seeking to address hormonal deficits.

How It Works

The mechanism of action of hCG revolves around its ability to bind to and activate luteinizing hormone (LH) receptors. In the ovary, this binding leads to the finalization of meiotic division in the oocyte and the secretion of estrogen, creating a favorable environment for fertilization.

In the testis, hCG activation of LH receptors on Leydig cells upregulates the expression of steroidogenic enzymes, resulting in increased synthesis of testosterone.

The half‑life of exogenous hCG after injection is approximately 24–36 hours, providing a sustained physiological effect that can be measured by serum hormone levels several days after administration. This prolonged activity allows for less frequent dosing schedules compared with shorter‑acting gonadotropins.

Dosage Guidelines

Dosage of hCG 5000IU must be individualized by a qualified healthcare professional based on the specific indication, patient weight, ovarian reserve, and treatment protocol. In ART cycles, a typical regimen involves a single 5000IU intramuscular or subcutaneous injection administered when follicular dimensions reach a predefined threshold, usually 18–20 mm.

For male hypogonadism, regimens may involve weekly or bi‑weekly injections, with dose adjustments guided by serum testosterone monitoring. Patients are advised never to self‑administer the medication without explicit instruction from their prescribing physician.

The drug should be reconstituted with the accompanying diluent according to the manufacturer’s directions, and the solution should be inspected for particulate matter before use. Proper injection technique, including site rotation and aseptic preparation, reduces the risk of local irritation.

Side Effects

Most adverse events associated with hCG are mild and localized, such as pain, erythema, or induration at the injection site. Systemic side effects can include headache, nausea, fatigue, and transient fluid retention.

In women, rare but serious complications may include ovarian hyperstimulation syndrome (OHSS), characterized by abdominal distension, shortness of breath, rapid weight gain, and decreased urine output; patients experiencing these symptoms should seek immediate medical attention.

Allergic reactions, though uncommon, can manifest as rash, pruritus, or, in severe cases, anaphylaxis. Patients with a history of hypersensitivity to gonadotropins should discuss alternative therapies with their clinician. Long‑term use may necessitate periodic assessment of liver function, lipid profile, and endocrine parameters to detect any emerging abnormalities.

Regular monitoring of serum hormone levels and relevant clinical parameters is recommended throughout therapy to assess response and to adjust dosing if necessary. In fertility treatments, ultrasound examinations are used to track follicular development, while in men hormone panels help ensure testosterone levels remain within the target range.

Warnings and Precautions

hCG is contraindicated in individuals with known hypersensitivity to the drug or any of its excipients. It should not be used in patients with hormone‑sensitive malignancies, such as certain ovarian or testicular cancers, unless under the supervision of an oncologist.

Women who are pregnant or breastfeeding must avoid hCG unless a specific therapeutic indication exists and is approved by a physician. Prior to initiation, clinicians should obtain a thorough medical history, including any current medications, especially those that may affect hormonal balance, such as clomiphene citrate or aromatase inhibitors.

The product must be stored refrigerated at 2 °C–8 °C and protected from light; freezing destroys the biological activity of the hormone. Baseline hormone panels, pelvic ultrasound, and, when indicated, imaging studies are recommended to assess suitability.

FAQs

Q1: What distinguishes hCG 5000IU from lower‑dose preparations?
A: The 5000IU formulation is the standard dose used for fertility indications, delivering a higher biological activity that can reliably trigger ovulation or stimulate testosterone production.

Q2: Can hCG be used after a positive pregnancy test?
No. Once pregnancy is confirmed, continued administration of hCG is generally discontinued, as exogenous hormone is no longer needed and may interfere with natural hormonal regulation.

Q3: How should the vial be stored and handled?
Store the unopened vial in a refrigerator (2 °C–8 °C) and keep it away from direct light. Once reconstituted, the solution should be used promptly, and any unused portion should be discarded according to local regulations.

Q4: Is it safe to self‑administer hCG at home?
Self‑administration is only recommended after a healthcare professional has demonstrated proper technique and provided written instructions. Patients must be trained in aseptic technique, site selection, and disposal of sharps.

Q5: Where can I purchase hCG 5000IU Injection?
The medication is available through licensed pharmaceutical distributors and authorized online retailers. Delivery typically takes 6 to 15 days, depending on the shipping destination.
