Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
A. P. L. (Chorionic Gonadotropin) acts as a luteinizing hormone (LH) agonist, binding to LH receptors in the gonads to stimulate testosterone production in males and ovulation in females.
Android 25 contains methyltestosterone, a synthetic androgen that binds to androgen receptors, promoting protein synthesis and anabolic effects. It also inhibits gonadotropin secretion from the pituitary, reducing endogenous testosterone production.
Induction of ovulation in anovulatory infertile women,Treatment of hypogonadism and cryptorchidism in males,Off-label: Assisted reproductive technology (ART) protocols
Hypogonadism in males (primary and secondary),Delayed puberty in males,Metastatic breast cancer in women (as palliative therapy)
500-1000 mg every 4-6 hours, not to exceed 3000 mg/day in adults.
Testosterone 25 mg subcutaneously or intramuscularly every 2 to 4 weeks. Alternatively, 125 mg intramuscularly every 10 days.
Terminal elimination half-life: 2.5–3.5 hours (elimination phase); clinical context: requires repeated dosing for sustained effect.
Terminal elimination half-life: 10–100 minutes (testosterone); clinical context: rapid clearance necessitates frequent dosing or use of esters for sustained effect
Primarily via glucuronidation (60%) and sulfation (35%) in the liver, with a minor portion (5%) via CYP2E1 oxidation to the toxic metabolite N-acetyl-p-benzoquinone imine (NAPQI), which is normally detoxified by glutathione.
Primarily hepatic via reduction and oxidation; metabolites include androsterone and etiocholanolone; excreted in urine.
Renal: 10% unchanged; hepatic metabolism to inactive metabolites excreted in urine and feces (90% combined).
Renal: 90% (as glucuronide and sulfate conjugates, 5–10% unchanged); fecal/biliary: 10%
80–90% bound to sex hormone-binding globulin (SHBG) and albumin.
97–99% (sex hormone-binding globulin and albumin)
0.5–0.9 L/kg, indicating moderate tissue distribution (primarily gonads and liver).
0.3–0.6 L/kg; indicates distribution into lean muscle and sex organs
IM: 100%; Subcutaneous: ~80% (relative to IM); Oral: <5% (not clinically used).
Oral: <5% (methyltestosterone: ~20–25% due to 17α-alkylation); IM: 100%
No specific adjustment required for mild to moderate renal impairment. In severe renal impairment (Cr Cl < 10 m L/min), extend dosing interval to every 8 hours.
No dose adjustment required for GFR ≥30 m L/min. For GFR <30 m L/min, consider reducing dose or increasing interval; monitor for fluid retention and hypertension.
Caution in severe hepatic impairment; consider dose reduction or extended interval. Avoid use in active liver disease.
Contraindicated in Child-Pugh class B or C cirrhosis. For mild hepatic impairment (Child-Pugh A), start with lower dose (e.g., 12.5 mg every 2 weeks) and titrate based on response and liver function.
Weight-based: 10-15 mg/kg every 4-6 hours, not to exceed 5 doses per day or 75 mg/kg/day.
Not recommended for use in pediatric patients (safety and efficacy not established). For male adolescents with hypogonadism, individualize: start at 12.5 mg every 2 weeks and adjust based on testosterone levels and growth.
No specific dose adjustment, but consider renal and hepatic function and avoid exceeding 3000 mg/day.
Start with lower initial dose (e.g., 12.5 mg every 2 weeks); monitor prostate-specific antigen (PSA) and hematocrit frequently. Avoid in patients with prostate cancer or untreated sleep apnea.
No black box warning.
WARNING: Androgens are contraindicated in pregnancy due to masculinization of female fetus. Hepatotoxicity, including peliosis hepatis and hepatic neoplasms, has been reported with prolonged use.
May cause fluid retention, ovarian hyperstimulation syndrome (OHSS) in females,Increased risk of thromboembolic events,Precocious puberty in males,Not for use in prepubertal children unless for cryptorchidism
Use with caution in patients with hepatic, renal, or cardiovascular disease; may cause gynecomastia, edema, hypercalcemia, and polycythemia; monitor liver function, lipid profile, and hematocrit periodically; may accelerate bone maturation in children; risk of prostate hypertrophy and urethral obstruction.
Hypersensitivity to chorionic gonadotropin or any component,Precocious puberty (in males),Prostatic carcinoma or other androgen-dependent neoplasms,Ovarian cyst or enlargement not due to polycystic ovary syndrome
Known or suspected prostate cancer; male breast cancer; pregnancy; lactation; hypersensitivity to methyltestosterone; severe hepatic impairment.
No known food interactions. Avoid alcohol during treatment.
Take with food containing fat (e.g., avocado, nuts, olive oil) to enhance absorption. Avoid grapefruit juice as it may increase testosterone levels via CYP3A4 inhibition. Limit alcohol due to potential liver effects.
A. P. L. (chorionic gonadotropin) is not expected to increase the risk of congenital anomalies when used in early pregnancy. However, use in the first trimester is generally avoided unless indicated for specific conditions. Data are limited; no increased fetal risk reported in inadvertent exposures. Second and third trimester use is not associated with teratogenicity but may increase risk of multiple gestation (if used for ovulation induction).
Android 25 (methyltestosterone) is an androgen. First trimester: Virilization of female fetus, including clitoromegaly, labial fusion, urogenital sinus abnormalities if exposure occurs before 12 weeks gestation. Second and third trimesters: Continued risk of female pseudohermaphroditism, and potential for masculinization of female external genitalia. Androgens can cross the placenta and may also cause skeletal abnormalities and growth retardation. Pregnancy category X.
Chorionic gonadotropin is not detected in breast milk following maternal administration. M/P ratio not established. Considered compatible with breastfeeding; no adverse effects on infant reported. Use with caution if high doses are administered.
Methyltestosterone is excreted into breast milk; M/P ratio not established. May cause virilization in female infants and premature sexual development in male infants. Androgens can suppress lactation. Use during breastfeeding is contraindicated.
No pharmacokinetic studies in pregnancy. Dose adjustments are not typically required during pregnancy for standard indications. For ovulation induction, dosing is based on follicular development. In first trimester for luteal support, standard doses are used. No evidence of altered clearance or need for dose changes due to pregnancy.
Android 25 is contraindicated in pregnancy, so no dosing adjustments are applicable. If used inadvertently, discontinue immediately. No pharmacokinetic data to guide dose changes; avoid use entirely.
A. P. L. (chorionic gonadotropin) is used to trigger ovulation in assisted reproductive technology. Administer when follicles are mature (≥18 mm). Risk of ovarian hyperstimulation syndrome (OHSS) increases with higher doses. Monitor for abdominal pain, distension, and weight gain. Use caution in patients with prior thromboembolism.
Android 25 (testosterone undecanoate) requires absorption via lymphatic system; administer with fat-containing meal. Monitor serum testosterone levels 3-5 hours post-dose. Avoid in patients with breast cancer or known or suspected prostate cancer. Risk of polycythemia; check hematocrit before and during therapy.
This medication is given as an injection exactly as prescribed to trigger ovulation.,A single dose is usually sufficient; follow your doctor's timing instructions closely.,Common side effects include headache, fatigue, and injection site reactions.,Seek immediate medical help if you experience severe pelvic pain, nausea, vomiting, or sudden weight gain (signs of OHSS).,Report symptoms of blood clots: leg pain, chest pain, or shortness of breath.
Take capsules with meals, especially those containing fat, to improve absorption.,Do not chew or crush capsules; swallow whole.,Report signs of deep vein thrombosis (leg swelling, pain) or pulmonary embolism (sudden dyspnea, chest pain).,Women of reproductive potential should avoid pregnancy; use effective contraception.,Keep out of reach of children; testosterone can cause serious harm if accidentally ingested.,Regular blood tests (testosterone, hematocrit, PSA, lipid profile) are required.
