GMH HP Injection (Menotrophin) Used to Treat Male and Female Infertility
GMH HP Injection (Menotrophin) is a medicine known as a sex hormone used to treat infertility in women who are not ovulating properly, male infertility, and male hypogonadism.
Product Overview
GMH HP Injection is a highly purified human menopausal gonadotropin (hMG) containing Menotrophin. GMH HP Injection is an essential hormonal therapy used in reproductive medicine to treat infertility in both women and men. By providing a standardized combination of follicle-stimulating and luteinizing activities, it supplements or replaces the natural hormones required to trigger the reproductive process, facilitating follicular growth in the ovaries and supporting sperm development in the testes.
Product Composition
- Active Ingredient: Menotrophin (Human Menopausal Gonadotropin)
- Hormonal Ratio: 1:1 ratio of Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) activity.
- Formulation: Lyophilized (freeze-dried) powder for injection, supplied with a separate ampoule of sterile solvent (Sodium Chloride).
- Common Strengths: 75 IU, 150 IU
- Purity Status: Highly Purified (HP), ensuring low levels of non-specific proteins and high batch-to-batch consistency.
Product Specifications

| Drug Category | Gonadotropin / Ovulation Inducer |
| Therapeutic Class | Infertility Management |
| Route of Administration | Subcutaneous (SC) or Intramuscular (IM) |
| Storage | Store at room temperature (below 25°C); protect from light |
Mechanism of Action
- Folliculogenesis Induction: In the female body, the FSH component of Menotrophin initiates the recruitment and growth of ovarian follicles. The LH component acts on the theca cells to promote the production of androgens, which are then converted into estrogens.
- Endometrial Priming: By stimulating the production of estradiol within the developing follicles, it helps thicken the uterine lining, preparing it for the potential implantation of an embryo.
- Gamete Maturation: It provides the necessary hormonal environment for the final stages of egg maturation before ovulation is triggered by other medications (like hCG).
- Testicular Stimulation: In males with specific hormonal deficiencies, Menotrophin acts directly on the Sertoli cells within the testes to stimulate and maintain spermatogenesis (the production of healthy sperm).
Key Benefits
- Dual Hormone Support: Unlike pure FSH preparations, the inclusion of LH activity is crucial for patients who have profound gonadotropin deficiencies and require both hormones for successful follicle development.
- High Tolerability: The Highly Purified (HP) nature of the formulation reduces the risk of local skin reactions and discomfort at the injection site.
- Predictable Response: Standardized bioactivity allows fertility specialists to precisely calibrate the dose to the patient's specific needs.
- Proven Efficacy in ART: A reliable choice for complex Assisted Reproductive Technology procedures, helping to optimize the number and quality of oocytes (eggs) retrieved.
- Versatile Application: Provides a vital therapeutic pathway for various endocrine-related fertility challenges in both genders.

Usage
GMH HP Injection is a specialized medication that requires administration under the guidance of a physician experienced in fertility treatment. Because it stimulates the reproductive organs directly, precise timing and clinical monitoring are essential to achieve the desired therapeutic outcome.
Dosage and Administration
Following the established injection protocol and monitoring schedule is critical for safety and success.
Administration Route: This injection is administered either Subcutaneously (SC) or Intramuscularly (IM). Subcutaneous injection in the abdominal area is often preferred for self-administration due to ease and comfort.
Preparation: Reconstitute the lyophilized powder only when you are ready to use it. Use the sterile solvent provided. Gently swirl the vial until the powder is completely dissolved; do not shake the vial vigorously.
Administration Timing: Injections should be given at the same time each day. For women, the treatment cycle usually begins within the first few days of the menstrual period.
Monitoring Protocol: Throughout the treatment, the patient must undergo regular transvaginal ultrasounds and blood tests (to measure estradiol levels). This allows the physician to monitor follicle growth and adjust the dose as needed.
Triggering Ovulation: When the follicles reach an optimal size (usually determined via ultrasound), a final injection of Human Chorionic Gonadotropin (hCG) is typically administered to induce the final release of the egg.
Storage and Disposal: The reconstituted solution must be used immediately. Any remaining liquid should be discarded. Always use a new sterile syringe and needle for every injection.
Safety Precaution: If signs of Ovarian Hyperstimulation Syndrome (OHSS) occur—such as severe pelvic pain, bloating, or nausea—contact your specialist immediately.
Missed Dose: If a dose is missed, do not double the next dose. Contact your fertility clinic immediately for guidance on how to adjust your schedule.
Uses
GMH HP Injection is indicated for the treatment of various hormonal and reproductive conditions in both women and men.
Primary Therapeutic Uses
Ovulation Induction: Indicated for women who are not ovulating or have irregular cycles, including those with Polycystic Ovary Syndrome (PCOS), who have not responded to simpler treatments.
Controlled Ovarian Hyperstimulation (COH): A primary component of Assisted Reproductive Technologies (ART) such as In Vitro Fertilization (IVF), used to stimulate the development of multiple follicles for egg retrieval.
Management of Hypogonadotropic Hypogonadism: Used in women with severe deficiencies in FSH and LH to restore the hormonal signals necessary for ovarian function.
Stimulation of Spermatogenesis: In men with hormonal deficiencies, it is used to stimulate the testes to produce healthy sperm, often as part of a long-term treatment plan combined with hCG.
Treatment of Luteal Phase Deficiency: Occasionally used to support the corpus luteum, ensuring adequate progesterone production to maintain the uterine lining for pregnancy.
Development of Secondary Sexual Characteristics: In specific cases of delayed puberty due to hypogonadism, it can be used to initiate the hormonal processes associated with reproductive maturity.
