Overview
HMG (Human Menopausal Gonadotropin) is “a purified gonadotropin preparation containing equal amounts of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) activity.” This peptide supports male fertility by stimulating sperm production in cases of hypogonadotropic hypogonadism or infertility.
Key Protocol Details
Dosing
– Dose: 75 IU per injection
– Frequency: Three times weekly (e.g., Monday, Wednesday, Friday)
– Duration: Minimum 12 weeks; may extend to 16 weeks
– Route: Subcutaneous injection
– Combination: Typically paired with hCG therapy for enhanced results
Reconstitution
– Volume: Add 3.0 mL bacteriostatic water per vial
– Concentration: 25 IU/mL
– Process: Inject slowly down vial wall, gently swirl until dissolved (avoid shaking)
– Labeling: Mark with date and time after reconstitution
Storage
– Lyophilized: Refrigerate 2–8°C (35.6–46.4°F); stable at 25°C (77°F)
– Reconstituted: Use promptly or refrigerate and use within days
– Protection: Keep away from light at all times
Mechanism of Action
HMG provides both FSH and LH in a 1:1 ratio, derived from purified human menopausal urine. In hypogonadal males, FSH stimulation is essential for spermatogenesis. Research shows that “HMG combined with hCG significantly improves sperm parameters including motility, morphology, and concentration.”
Benefits
– Stimulates spermatogenesis in men with hormonal deficiencies
– Improves sperm motility and morphology
– Increases pregnancy rates when combined with hCG
– Supports normal testicular function
Potential Side Effects
– Injection site reactions (redness, swelling, discomfort)
– Headache or fatigue
– Gynecomastia (breast tissue development)
– Rare allergic reactions
Administration Guidelines
1. Wash hands and prepare clean workspace
2. Cleanse vial stopper with alcohol swab; allow to dry
3. Draw 3.0 mL dose with sterile syringe
4. Select injection site with adequate fat (abdomen, thigh, upper arm)
5. Cleanse skin; insert needle at 90° angle
6. Inject slowly over several seconds
7. Rotate injection sites (minimum 1 inch apart)
8. Dispose of needle in sharps container immediately
Important Notes
– Clinical response typically requires at least 12 weeks
– Spermatogenesis development may take 3–6 months
– Monitor semen parameters and hormone levels throughout therapy
– Use new sterile syringes for each injection
– The 3.0 mL volume may require splitting into multiple smaller injections using insulin syringes
Lifestyle Support
– Maintain healthy body weight with antioxidant-rich nutrition
– Avoid excessive heat exposure to testes
– Limit alcohol; avoid tobacco and drugs
– Manage stress through adequate sleep and exercise
– Consider evidence-based supplements (CoQ10, L-carnitine) with medical guidance
