Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Chorionic gonadotropin (h CG) binds to the luteinizing hormone/choriogonadotropin receptor (LHCGR) on the surface of gonadal cells, stimulating steroidogenesis and gametogenesis. In females, it triggers ovulation and luteinization; in males, it stimulates Leydig cells to produce testosterone.
Androgen receptor agonist; stimulates protein synthesis and growth of androgen-sensitive tissues.
FDA-approved: Induction of ovulation in infertile females (as part of controlled ovarian hyperstimulation),FDA-approved: Treatment of prepubertal cryptorchidism,FDA-approved: Treatment of hypogonadotropic hypogonadism in males,Off-label: Weight loss (not recommended),Off-label: In vitro fertilization protocols
Testosterone replacement therapy for male hypogonadism,Off-label: delayed puberty in males
For hypogonadotropic hypogonadism: 1000-2000 IU subcutaneously or intramuscularly 2-3 times per week. For ovulation induction: 5000-10,000 IU intramuscularly as a single dose.
2.5-10 mg orally once daily in the morning for androgen replacement therapy in adult males.
Biphasic: initial half-life ~11 hours, terminal half-life ~23–30 hours. Single-dose half-life ~32 hours; repeated dosing may extend due to accumulation.
Terminal elimination half-life is 3.5–5.5 hours; clinical effects may persist for several days due to active metabolites.
Primarily metabolized in the liver via proteolytic degradation; undergoes renal excretion with a half-life of 24-36 hours.
Hepatic via CYP3A4 and CYP2B6; undergoes first-pass metabolism.
Primarily renal; intact h CG is excreted in urine. Negligible biliary/fecal elimination.
Primarily renal: ~90% as glucuronide and sulfate conjugates, 6% as unchanged drug; ~5% fecal via bile.
Approximately 80% bound; binds to albumin and sex hormone-binding globulin (SHBG) with low affinity.
98% bound to sex hormone-binding globulin (SHBG) and albumin.
0.3–0.5 L/kg; distributes into extracellular fluid, gonadal tissues, and poorly into fat.
Vd approximately 1.0 L/kg; indicates extensive tissue distribution, especially to reproductive organs and bone marrow.
IM/SC: ~40% to 100% (mean ~78%) due to variable absorption; IV: 100% (not typical). Oral: negligible (<1% due to degradation).
Oral: 15–25% due to first-pass metabolism; buccal or transdermal: higher, but not commercially available for this formulation.
No specific dose adjustment guidelines available; use with caution in severe renal impairment (GFR <30 m L/min/1.73 m²).
No specific dose adjustment required based on GFR; caution in severe impairment (Cr Cl <30 m L/min) due to potential fluid retention.
No specific dose adjustment guidelines available; use with caution in severe hepatic impairment (Child-Pugh class C).
Contraindicated in Child-Pugh class B and C cirrhosis due to hepatotoxicity risk; in class A, use with caution and monitor liver function.
Cryptorchidism: 500-1000 IU subcutaneously or intramuscularly 2-3 times per week for 6 weeks. Delayed puberty: 500-1500 IU subcutaneously or intramuscularly 2-3 times per week.
Not recommended for use in children as it may cause premature epiphyseal closure and virilization; limited data.
No specific dose adjustments; monitor for fluid retention and cardiovascular effects.
Increased risk of prostatic hyperplasia and carcinoma; use lowest effective dose with regular prostate monitoring.
None. However, use in females requires careful monitoring to avoid ovarian hyperstimulation syndrome (OHSS), which can be severe.
Warning: Prolonged use may cause virilization in women, premature epiphyseal closure, and increased risk of prostatic hypertrophy/carcinoma.
Ovarian hyperstimulation syndrome (OHSS): Risk of severe OHSS with ascites, pleural effusion, and thromboembolic events,Multiple pregnancy: Increased risk due to ovulation induction,Thromboembolic events: Increased risk, especially in patients with prior history,Ovarian enlargement: Monitor with ultrasound,Hormonal-dependent malignancies: Caution in patients with prior history
Monitor liver function, lipid profile, and prostate-specific antigen; risk of edema in patients with cardiac disease; avoid use in patients with sleep apnea.
Pregnancy,Primary ovarian failure,Uncontrolled thyroid or adrenal dysfunction,Active thromboembolic disorder,Hormone-sensitive tumors (e.g., prostate, breast, ovarian),Hypersensitivity to h CG or any component
Known or suspected prostate cancer; breast cancer in males; hypersensitivity to androgens; pregnancy and lactation.
No known food interactions.
Avoid grapefruit and grapefruit juice as they may increase drug levels. Limit salt intake to reduce fluid retention. Alcohol may increase risk of liver toxicity.
Chorionic gonadotropin is a pregnancy hormone; exogenous use during first trimester may theoretically alter placental hormone balance, but no increased risk of congenital anomalies has been established. However, use during pregnancy is contraindicated except as part of assisted reproductive technology protocols where its role is physiological. No fetal risks documented from therapeutic use in second or third trimester.
Pregnancy Category X. ANDROID 5 (oxandrolone) is contraindicated in pregnancy due to teratogenic effects including masculinization of female fetus, clitoral enlargement, and labial fusion. Risk is highest during first trimester but applies throughout gestation.
Chorionic gonadotropin is not orally bioavailable and is likely degraded in infant gastrointestinal tract. Excretion into breast milk is unknown; M/P ratio not established. However, due to its protein nature, transfer is expected to be minimal. Use during breastfeeding is not recommended unless clearly necessary; theoretical risk of hormonal effects on infant.
Excretion into human milk is unknown. Due to potential for androgenic effects in nursing infants, breastfeeding is not recommended. No M/P ratio available.
No pharmacokinetic dose adjustments are recommended in pregnancy as the drug is typically administered only prior to conception or in early pregnancy for luteal phase support. The endogenous hormone levels in pregnancy far exceed exogenous doses. No dose modification required in later trimesters because use is contraindicated.
Not applicable; contraindicated in pregnancy. No dose adjustment recommendations exist for pregnant patients.
Chorionic gonadotropin (h CG) is used to trigger ovulation in assisted reproduction and to treat hypogonadotropic hypogonadism in males. Monitor for ovarian hyperstimulation syndrome (OHSS) in women; discontinue if severe. Do not use in women with primary ovarian failure. In males, may cause gynecomastia or fluid retention.
Android 5 (methyltestosterone) is an androgenic anabolic steroid used for hypogonadism and delayed puberty. Monitor liver function due to hepatotoxicity. Use with caution in elderly due to increased risk of prostatic hypertrophy and carcinoma. Can cause fluid retention in patients with cardiac, renal, or hepatic disease. Avoid in patients with breast cancer or known or suspected prostate cancer.
Report abdominal pain, bloating, nausea, vomiting, or rapid weight gain (signs of OHSS).,In males, report breast tenderness or swelling, or fluid retention (swollen ankles/feet).,Do not use if pregnant or breastfeeding unless directed by a specialist.,For fertility: timing of intercourse or IUI is critical; follow cycle monitoring closely.,In males: take as prescribed for testicular descent or hypogonadism; may require multiple doses.
Take exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Report any signs of liver problems: yellowing of skin or eyes, dark urine, severe stomach pain.,Women should report any signs of virilization: hoarseness, acne, menstrual changes, growth of facial hair.,Men should report any breast enlargement, changes in urination, or priapism.,Avoid driving or operating machinery if you experience dizziness or drowsiness.,Do not use if you are pregnant or planning to become pregnant.
