Meta Information
ID:hcg
Name:
Schema Version:AIM-2.0
Interactions
Target id:
/condition/hormone-sensitive-cancer
Target name:
Hormone-Sensitive Cancers (Prostate, Breast)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
hCG stimulates testosterone and estrogen production, which can promote the growth of hormone-dependent tumors like prostate or breast cancer.
Actionable advice:
Avoid completely if you have a current or past diagnosis of a hormone-sensitive cancer.
Target id:
/condition/pregnancy
Target name:
Pregnancy
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Exogenous hCG is classified as Pregnancy Category X; it offers no benefit during an established pregnancy and may cause fetal harm.
Actionable advice:
Do not use if you are pregnant.
Target id:
/intervention/testosterone_systemic_healthspan
Target name:
Testosterone Replacement Therapy (TRT)
Severity:
major
Interaction type:
synergistic
Nature:
absolute
Temporal spacing:
null
Description:
hCG mimics Luteinizing Hormone (LH) to directly stimulate the testes, preventing the testicular atrophy and loss of fertility commonly caused by exogenous testosterone.
Actionable advice:
Use as prescribed alongside TRT to maintain testicular function and fertility.
Target id:
/biomarker/lh
Target name:
Luteinizing Hormone (LH) Blood Test
Severity:
major
Interaction type:
assay_interference
Nature:
absolute
Temporal spacing:
null
Description:
hCG is structurally similar to LH and will cross-react with most laboratory immunoassays, causing a falsely high or uninterpretable LH level.
Actionable advice:
Inform the lab and your doctor that you are taking hCG when getting an LH test; the result will not reflect your natural pituitary output.
Target id:
/procedure/urine-pregnancy-test
Target name:
Urine Pregnancy Test
Severity:
major
Interaction type:
assay_interference
Nature:
absolute
Temporal spacing:
null
Description:
Urine pregnancy tests work by detecting hCG. Exogenous administration of hCG will result in a false positive test.
Actionable advice:
Do not rely on urine pregnancy tests while using hCG; use a blood test for confirmation if pregnancy is suspected.
Target id:
/biomarker/estradiol
Target name:
Estradiol (E2)
Severity:
major
Interaction type:
requirement
Nature:
absolute
Temporal spacing:
null
Description:
The testosterone produced via hCG stimulation can be converted to estradiol by the aromatase enzyme; levels must be monitored to prevent side effects from high estrogen.
Actionable advice:
Regularly monitor estradiol levels to manage potential estrogenic side effects like water retention or gynecomastia.
Target id:
/biomarker/total-testosterone
Target name:
Total Testosterone
Severity:
major
Interaction type:
requirement
Nature:
absolute
Temporal spacing:
null
Description:
hCG directly stimulates testosterone production, and levels must be monitored to ensure the dose is therapeutic and not excessive.
Actionable advice:
Regularly monitor total and free testosterone levels to guide appropriate dosing.
Target id:
/class/gnrh-analogs
Target name:
GnRH Analogs (e.g., Leuprolide)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
GnRH analogs suppress natural gonadotropin production, while hCG acts as a gonadotropin substitute; their concurrent use is pharmacologically contradictory.
Actionable advice:
Avoid using together unless specifically directed by an endocrinologist for a specialized protocol (e.g., IVF).
Target id:
/condition/heart-failure
Target name:
Heart Failure
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
hCG can cause sodium and fluid retention, potentially worsening edema and exacerbating heart failure.
Actionable advice:
Use with extreme caution and under close medical supervision if you have heart failure.
Target id:
/condition/renal-impairment
Target name:
Renal Impairment
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
hCG can cause fluid retention, which may strain compromised kidneys and worsen renal impairment.
Actionable advice:
Use with caution and monitor for fluid retention if you have kidney disease.
Target id:
/class/anticoagulants-antiplatelets
Target name:
Anticoagulants and Antiplatelets
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
hCG may increase the risk of thromboembolic events (blood clots), potentially altering the required dosage or increasing the risk profile of anticoagulant medications.
Actionable advice:
Use with caution and discuss with your doctor, as closer monitoring of clotting factors may be required.
Target id:
/condition/seizure-disorder
Target name:
Seizure Disorder / Epilepsy
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Fluid and electrolyte changes induced by hCG may lower the seizure threshold in susceptible individuals.
Actionable advice:
Use with caution and under medical supervision if you have a history of seizures.
Target id:
/biomarker/complete-blood-count
Target name:
Complete Blood Count (CBC)
Severity:
moderate
Interaction type:
requirement
Nature:
absolute
Temporal spacing:
null
Description:
hCG increases androgens, which can stimulate red blood cell production. Monitoring hematocrit is necessary to screen for polycythemia (thickened blood).
Actionable advice:
Monitor your CBC, specifically hematocrit and hemoglobin, every 3-6 months.
Target id:
/biomarker/prostate-specific-antigen
Target name:
Prostate Specific Antigen (PSA)
Severity:
moderate
Interaction type:
requirement
Nature:
absolute
Temporal spacing:
null
Description:
The increase in testosterone from hCG can stimulate prostate tissue. Regular PSA monitoring is a standard precaution for men on any androgen-boosting therapy.
Actionable advice:
Monitor PSA levels at baseline and periodically as recommended by your physician.
Target id:
/intervention/enclomiphene
Target name:
Enclomiphene / Clomiphene
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Temporal spacing:
null
Description:
Enclomiphene stimulates the pituitary to produce LH, while hCG acts as an LH analog on the testes. Using them together can create a powerful, combined stimulus for testosterone production.
Actionable advice:
Combine only under expert medical supervision to avoid excessive hormone production and side effects.
Target id:
/condition/migraines
Target name:
Migraines
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
hCG-induced changes in testosterone and estrogen levels can trigger or worsen migraine headaches in susceptible individuals.
Actionable advice:
Monitor for increased migraine frequency or severity when starting hCG.
Target id:
/condition/pediatric
Target name:
Pediatric Use (Pre-pubertal)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
hCG can induce premature puberty in children by stimulating sex hormone production.
Actionable advice:
Contraindicated for use in pre-pubertal children except under strict medical supervision for specific conditions.
Target id:
/condition/asthma-copd
Target name:
Asthma
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Fluid retention caused by hCG could theoretically exacerbate asthma symptoms, although this is a rare concern.
Actionable advice:
Use with caution and monitor respiratory symptoms if you have asthma.
