Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Testosterone is an androgen receptor agonist; it binds to androgen receptors, leading to changes in gene expression that promote male secondary sexual characteristics and maintain libido, muscle mass, and bone density.
Androgen receptor agonist; stimulates protein synthesis and growth of androgen-sensitive tissues.
FDA-approved: testosterone replacement therapy in males for conditions associated with a deficiency or absence of endogenous testosterone (hypogonadism). Off-label: delayed puberty in males, female-to-male transgender hormone therapy.
Testosterone replacement therapy for male hypogonadism,Off-label: delayed puberty in males
Apply one 2.5 mg or 5 mg transdermal system to clean, dry, intact skin on the abdomen, upper arms, or thighs once daily, preferably in the morning. Starting dose is 5 mg daily; adjust based on serum testosterone levels.
2.5-10 mg orally once daily in the morning for androgen replacement therapy in adult males.
Terminal elimination half-life is approximately 10–100 minutes (rapid), but due to transdermal absorption, effective half-life is extended to about 8–10 hours after patch application.
Terminal elimination half-life is 3.5–5.5 hours; clinical effects may persist for several days due to active metabolites.
Testosterone is metabolized primarily in the liver via CYP3A4 and CYP2C9 isoenzymes, as well as by 5α-reductase to dihydrotestosterone (DHT) and by aromatase to estradiol.
Hepatic via CYP3A4 and CYP2B6; undergoes first-pass metabolism.
Approximately 90% of testosterone metabolites are excreted in urine as glucuronide and sulfate conjugates; 6% are excreted in feces via bile.
Primarily renal: ~90% as glucuronide and sulfate conjugates, 6% as unchanged drug; ~5% fecal via bile.
Approximately 98–99% bound: primarily to sex hormone-binding globulin (SHBG, ~40%) and albumin (~60%).
98% bound to sex hormone-binding globulin (SHBG) and albumin.
Volume of distribution is approximately 0.2–0.8 L/kg, reflecting distribution into steroid-sensitive tissues and binding proteins.
Vd approximately 1.0 L/kg; indicates extensive tissue distribution, especially to reproductive organs and bone marrow.
Transdermal bioavailability is approximately 10–15% of the nominal dose (based on 24-hour application), with interindividual variability due to skin permeability.
Oral: 15–25% due to first-pass metabolism; buccal or transdermal: higher, but not commercially available for this formulation.
No specific dose adjustment recommended for renal impairment. Use with caution in patients with severe renal impairment due to potential fluid retention.
No specific dose adjustment required based on GFR; caution in severe impairment (Cr Cl <30 m L/min) due to potential fluid retention.
Contraindicated in patients with severe hepatic impairment (Child-Pugh class C). In mild to moderate impairment (Child-Pugh A or B), use with caution and monitor liver function; no specific dose adjustment guidelines.
Contraindicated in Child-Pugh class B and C cirrhosis due to hepatotoxicity risk; in class A, use with caution and monitor liver function.
Not indicated for use in pediatric patients. Safety and efficacy have not been established in children <18 years.
Not recommended for use in children as it may cause premature epiphyseal closure and virilization; limited data.
Initiate at 2.5 mg once daily in elderly patients due to increased risk of adverse effects, particularly prostatic hyperplasia and cardiovascular events. Monitor serum testosterone levels and adjust as needed.
Increased risk of prostatic hyperplasia and carcinoma; use lowest effective dose with regular prostate monitoring.
WARNING: Cardiovascular risk - Increased risk of myocardial infarction, stroke, and cardiovascular death has been reported with testosterone replacement therapy. Only use in men with confirmed hypogonadism.
Warning: Prolonged use may cause virilization in women, premature epiphyseal closure, and increased risk of prostatic hypertrophy/carcinoma.
Elderly patients and those with known cardiovascular risk factors should be monitored for cardiovascular events.,May exacerbate sleep apnea in predisposed individuals.,Can cause erythrocytosis; monitor hematocrit.,May accelerate growth of prostate cancer and benign prostatic hyperplasia; monitor prostate-specific antigen (PSA).,Monitor for signs of virilization in women if used off-label.,Possible hypercalcemia in immobilized patients.
Monitor liver function, lipid profile, and prostate-specific antigen; risk of edema in patients with cardiac disease; avoid use in patients with sleep apnea.
Men with carcinoma of the breast or known or suspected carcinoma of the prostate.,Women who are pregnant or may become pregnant (risk of virilization of fetus).,Hypersensitivity to testosterone or any component of the product.,Severe renal or hepatic impairment (risk of fluid retention).
Known or suspected prostate cancer; breast cancer in males; hypersensitivity to androgens; pregnancy and lactation.
No known food interactions. Take with or without food.
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.
Androderm (testosterone) is contraindicated in pregnancy due to virilization of female fetus. First trimester: high risk of pseudohermaphroditism in female fetuses (labial fusion, clitoromegaly) with androgen exposure during critical period of genital differentiation (weeks 8-12). Second and third trimesters: risk of clitoral enlargement, advanced bone age, and potential long-term behavioral effects. Male fetuses may experience premature sexual development. No adequate studies; USP pregnancy category X.
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.
Testosterone is excreted into human milk; M/P ratio not established. Potential for virilization of female infants and early puberty in male infants. Risk of suppression of maternal lactation (androgen-induced decrease in prolactin). Contraindicated during breastfeeding; alternative therapies recommended.
Excretion into human milk is unknown. Due to potential for androgenic effects in nursing infants, breastfeeding is not recommended. No M/P ratio available.
Androderm is contraindicated in pregnancy; no dose adjustments applicable. If therapy is necessary for maternal hypogonadism, discontinue immediately upon pregnancy recognition. Pharmacokinetic changes in pregnancy (increased clearance, volume of distribution) are irrelevant due to contraindication. Do not dose in pregnancy.
Not applicable; contraindicated in pregnancy. No dose adjustment recommendations exist for pregnant patients.
Apply to clean, dry, intact skin on the abdomen, thighs, upper arms, or back. Rotate application sites to minimize skin reactions. Do not apply to genitals or scrotum. Avoid showering or swimming for at least 3-4 hours after application to ensure absorption. Monitor serum testosterone levels 14 days after starting therapy or dose adjustment, drawn in the morning before application. Use with caution in patients with known or suspected prostate cancer or breast cancer. Warn patients about the risk of transfer to women and children through skin contact; cover application site with clothing or wash skin before contact.
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.
