HMG dosage chart

Reconstitution steps

1. 1Draw 3.0 mL bacteriostatic water with a sterile 3 mL syringe.
2. 2Inject slowly down the vial wall to avoid foaming.
3. 3Gently swirl or roll the vial until fully dissolved (do not shake).
4. 4Label with date and time; refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.
5. 5For optimal potency, use reconstituted solution promptly or within a few days.

Important Notes

Practical considerations for safe and effective administration.

• HMG therapy typically requires concurrent hCG administration for optimal results in males.
• Use new sterile syringes for each injection; dispose in a sharps container.
• Rotate injection sites (abdomen, thighs, upper arms) at least 1 inch apart to prevent lipohypertrophy or irritation.
• The 3.0 mL injection volume may require splitting into multiple smaller injections or using larger-capacity syringes.
• Monitor semen parameters and hormone levels throughout therapy to assess response.
• Clinical response typically requires at least 12 weeks; spermatogenesis may take 3–6 months to fully develop.

How This Works

HMG provides both FSH and LH activity in a 1:1 ratio, derived from purified human menopausal urine. In males with hypogonadotropic hypogonadism, FSH stimulation is essential for spermatogenesis (sperm production). When hCG alone fails to induce adequate sperm production, adding HMG provides the necessary FSH activity to support testicular function and fertility. Clinical studies demonstrate that HMG combined with hCG significantly improves sperm parameters including motility, morphology, and concentration, with enhanced pregnancy rates in treated couples.

Potential Benefits & Side Effects

Observations from clinical fertility literature.

• Stimulates spermatogenesis in men with hypogonadotropic hypogonadism or secondary infertility.
• Improves sperm motility, morphology, and concentration when combined with hCG therapy.
• Significantly increases pregnancy rates in couples undergoing fertility treatment.
• Supports normal testicular function and hormone production.
• Injection site reactions (redness, swelling, mild pain).
• Headache, fatigue, or mood changes (uncommon).
• Gynecomastia (breast tissue development) due to hormonal stimulation.
• Overstimulation effects if dosing is excessive (rare in males with proper monitoring).
• Allergic reactions (rare); discontinue if hypersensitivity occurs.

Lifestyle Factors

Complementary strategies to support fertility outcomes.

• Maintain healthy body weight and balanced nutrition rich in antioxidants (zinc, selenium, vitamin C, vitamin E).
• Avoid excessive heat exposure to testes (hot tubs, saunas, tight clothing).
• Limit alcohol consumption and avoid tobacco and recreational drugs.
• Manage stress through adequate sleep, exercise, and relaxation techniques.
• Regular moderate exercise supports hormonal balance (avoid excessive endurance training).
• Consider coenzyme Q10, L-carnitine, or other evidence-based supplements after consultation.

Injection Technique

Proper subcutaneous injection technique for HMG administration.

For Split-Dose Administration: If using 1 mL insulin syringes, divide the 3 mL total into three separate 1 mL injections at different sites (each containing 25 IU). Complete all three injections during the same administration session.

• Wash hands thoroughly and gather supplies on a clean surface.
• Clean the vial stopper with an alcohol swab and allow to dry.
• Draw up the prescribed dose using a sterile syringe (3 mL capacity for full 75 IU dose).
• Select an injection site with adequate subcutaneous fat (lower abdomen at least 2 inches from navel, outer thigh, or upper arm).
• Clean the injection site with a fresh alcohol swab; let dry completely.
• Pinch about an inch of skin to create a fold of subcutaneous tissue.
• Insert needle at a 90° angle (or 45° if very little subcutaneous fat) into the tissue.
• Release the pinch and slowly inject the medication over several seconds.
• Withdraw the needle smoothly and apply gentle pressure with sterile gauze (do not rub the site).
• Dispose of used syringe immediately in a sharps container.
• Rotate injection sites with each administration, maintaining at least 1 inch spacing from previous sites.
