Key Clinical Applications
Assisted Reproductive Technology (ART): During IVF-ET cycles, when a dominant follicle reaches maturity (diameter ≥17 mm), HCG is injected to mimic the LH surge and trigger final oocyte maturation; oocyte retrieval is typically performed 34–36 hours post-injection. The standard dosage is 5,000–10,000 IU.
Anovulatory Infertility: For patients with anovulation unresponsive to clomiphene, HCG is used in combination with human menopausal gonadotropin (HMG) to induce ovulation once follicles have matured.
Luteal Phase Defect: Administration of HCG after ovulation helps maintain luteal function, promotes sustained progesterone secretion, supports endometrial receptivity, and reduces the risk of early miscarriage.
Male Hypogonadism: Used to treat male infertility caused by gonadotropin deficiency; it stimulates the testes to produce testosterone and promotes spermatogenesis, often in combination with HMG.
Prepubertal Cryptorchidism: Used for the diagnosis and treatment of cryptorchidism (undescended testes) not caused by anatomical obstruction, facilitating testicular descent.
Threatened and Habitual Miscarriage: HCG supplementation in early pregnancy maintains luteal function and progesterone levels, supporting stable embryonic implantation and development.
Potential Benefits in Bodybuilding
Among bodybuilders and strength athletes, HCG is primarily utilized during two phases: the steroid cycle ("On-Cycle") and post-cycle recovery (PCT). The underlying rationale is as follows:
Prevention of Testicular Atrophy: Long-term use of exogenous anabolic steroids strongly suppresses the hypothalamic-pituitary-gonadal (HPTA) axis, causing endogenous LH secretion to drop to near-zero levels; the testes atrophy due to the lack of LH stimulation. HCG directly mimics LH signaling-bypassing the pituitary-to continuously stimulate testicular Leydig cells and maintain testosterone synthesis, thereby effectively preventing or reversing testicular atrophy.
Preparation for PCT: Prior to initiating PCT (i.e., before the introduction of Clomiphene or Tamoxifen), HCG is used to restore testicular volume and activity. This sensitizes the testes to the recovery-promoting effects of subsequent SERM medications, thereby shortening the overall recovery period. Maintaining Training Status: Low-dose HCG during a cycle helps maintain testosterone levels, mitigating issues such as reduced libido, low mood, and diminished training motivation caused by HPTA suppression.
Supporting Fertility: Studies show that during ongoing androgen use, HCG therapy significantly increases total sperm count and total motile sperm count-restoring levels to normal in 58% of patients-thereby offering a harm-reduction strategy for athletes wishing to preserve fertility.
Storage and Usage Instructions
1. Storage Conditions
Unreconstituted state: Store the lyophilized powder at 2–8°C, protected from light.
After reconstitution: Refrigeration is recommended; use within the specified timeframe.
Transport conditions: Cold-chain transport is required to ensure product potency.
2. Reconstitution Method
Reconstitute using the provided sterile water for injection or bacteriostatic water for injection. According to product specifications, the 5,000 IU vial is typically reconstituted with 1 mL of solvent to achieve a concentration of 5,000 IU/mL.
3. Administration
Route of administration: Subcutaneous or intramuscular injection.
Reference protocols for bodybuilding:
During-cycle use: 250–500 IU, 2–3 times per week.
Post-cycle recovery: Short-term protocol; specific dosages should be adjusted based on individual needs.
Important Note: The above protocols are for reference only; actual use should be guided by a medical professional.
