The Short Version
Plain-language summary
AndroGel (Testosterone) replaces the hormone your body isn't producing enough of. In men, this affects energy, muscle mass, bone density, mood, and sex drive. It's FDA-approved for diagnosed low testosterone, not age-related decline.
How it works: Testosterone is the primary androgen hormone produced in men (primarily by the testes) and at much lower levels in women (by the ovaries and adrenal glands). It acts by binding to androgen receptors (AR) found in muscle, bone, brain, skin, reproductive organs, and many other tissues. Once bound, the testosterone-androgen receptor complex regulates gene expression affecting muscle protein synthesis, bone density, red blood cell production, mood, libido, and secondary sexual characteristics.
What people most commonly report
Dose-dependent; often improves with dose reduction. Topical retinoids and non-comedogenic skincare may help.
Most studies were paid for by the company that makes this drug.
What Else the Evidence Supports
Non-drug options with clinical backing
Testosterone levels are significantly influenced by lifestyle. Several well-studied factors affect endogenous testosterone production, these are important to evaluate and address before or alongside any pharmacological intervention, as they represent root causes rather than symptoms.
Studies suggest 15-40% increases in testosterone levels with consistent resistance training programs; effects are largest in previously sedentary individuals.
A JAMA Internal Medicine study found 1 week of sleep restriction (5hrs/night) reduced daytime testosterone by 10-15% in healthy young men.
Studies show testosterone levels correlate inversely with body fat percentage; weight loss of 5-10% may raise testosterone meaningfully in overweight hypogonadal men.
Supplementation in deficient individuals, not those with adequate levels, shows testosterone-supporting effects in multiple studies.

FDA Black Box Warning
SECONDARY EXPOSURE (GEL) & ABUSE POTENTIAL
Topical testosterone can transfer to others through skin contact, causing virilization in women and premature puberty in children. Testosterone is a Schedule III controlled substance with abuse potential, particularly by athletes and bodybuilders. Misuse can cause serious cardiovascular harm.

Lifestyle Factors That Support Testosterone Levels
Testosterone levels are significantly influenced by lifestyle. Several well-studied factors affect endogenous testosterone production, these are important to evaluate and address before or alongside any pharmacological intervention, as they represent root causes rather than symptoms.
Important context: Evidence quality varies across these approaches. Some are well-studied with randomized controlled trial data; others are based on observational or smaller studies. These interventions are not guaranteed to replace medication for all patients. Discuss with your doctor whether any of these are appropriate for your clinical situation.
Resistance training (3-4×/week)
Compound movements (squat, deadlift, press) are associated with acute and chronic increases in testosterone and growth hormone in men
Studies suggest 15-40% increases in testosterone levels with consistent resistance training programs; effects are largest in previously sedentary individuals
Sleep optimization (7-9 hours)
The majority of daily testosterone secretion occurs during sleep, particularly during slow-wave sleep. Sleep restriction significantly suppresses morning testosterone.
A JAMA Internal Medicine study found 1 week of sleep restriction (5hrs/night) reduced daytime testosterone by 10-15% in healthy young men
Body weight management
Adipose tissue (particularly visceral fat) converts testosterone to estrogen via aromatase. Excess adiposity is associated with lower testosterone and higher estradiol in men.
Studies show testosterone levels correlate inversely with body fat percentage; weight loss of 5-10% may raise testosterone meaningfully in overweight hypogonadal men
Zinc and Vitamin D adequacy
Zinc is required for testosterone synthesis; vitamin D receptors are expressed in testicular Leydig cells. Deficiency of either is associated with lower testosterone.
Supplementation in deficient individuals, not those with adequate levels, shows testosterone-supporting effects in multiple studies
Key Studies
Global Prescribing & Pricing
US testosterone prescribing tripled between 2000-2013, driven significantly by direct-to-consumer marketing; other countries did not see comparable increases
United States
$80–300/mo
Highest testosterone prescribing rate in the world; "Low T" marketing significantly expanded the diagnosed population in 2000s-2010s
FDA requires cardiovascular warning label added in 2015; ongoing monitoring of prescribing appropriateness
Often covered with hypogonadism diagnosis; may require prior authorization
United Kingdom
~$10–30/mo
NICE guidance requires confirmed biochemical hypogonadism (morning testosterone, repeated) before prescribing
NHS restricts prescribing to specialists (endocrinology, urology); GP prescribing for "Low T" is not standard practice
Covered by NHS with confirmed diagnosis
Germany
~$15–40/mo
Requires two confirmed low testosterone readings before prescribing; prescribing rate much lower than US
German Endocrine Society guidelines emphasize confirming true hypogonadism vs. age-related decline
Covered by GKV with diagnosis
Australia
~$10–35/mo
TGA monitoring identified a prescribing increase; Endocrine Society of Australia guidelines require documentation of symptoms + biochemical confirmation
Australia approved testosterone for women (Androfeme 1%), the only country with a specifically approved female testosterone product
PBS subsidized for confirmed hypogonadism
Canada
~$20–60/mo
Lower prescribing rate than the US; no direct-to-consumer advertising of prescription drugs
Canada bans DTC pharmaceutical advertising, no "Low T" TV campaigns; prescribing driven by clinical presentation
Provincial coverage varies
The US testosterone prescribing surge was directly correlated with a $194M/year marketing campaign. Canada and the UK, which ban or limit direct-to-consumer pharmaceutical advertising, did not see comparable increases, suggesting the prescribing expansion was at least partially marketing-driven rather than purely clinically driven.
Clinical Trials & Funding
Understanding who funds research helps contextualize results. Industry-funded trials are not automatically invalid - they undergo the same FDA review - but declared conflicts and sponsor effects are worth knowing. All linked trials can be verified on ClinicalTrials.gov.
Key Efficacy Results
TOM trial: Stopped early, excess cardiovascular events in older men on testosterone vs. placebo. TRAVERSE: Testosterone non-inferior to placebo for major cardiovascular events in hypogonadal men with or at high risk for cardiovascular disease. Women: systematic review found benefit for sexual function at physiological doses; long-term safety data limited.

Our MethodologyCommon Side Effects
While taking this medication, you may experience the following common side effects. We've included tips on how to manage them.
Acne
10-15%Dose-dependent; often improves with dose reduction. Topical retinoids and non-comedogenic skincare may help.
Erythrocytosis (high red blood cell count)
5-15%Elevated hematocrit increases blood viscosity and clot risk, monitored routinely with CBC. Dose reduction or blood donation may be recommended.
Testicular atrophy (men)
Very commonExogenous testosterone suppresses the HPG axis, reducing natural testosterone production and sperm count, causing testicular shrinkage. HCG co-prescription is used to partially mitigate this.
Reduced sperm count / infertility (men)
Common with extended useTestosterone suppresses FSH and LH, markedly reducing sperm production. This effect may be reversible but can take months to years to recover, important to discuss before starting if future fertility matters.
Mood changes / irritability
5-10%Particularly with large dose fluctuations (injection peaks and troughs). More stable delivery (gel, patch) may reduce mood swings.
Sleep apnea worsening
5-10%Testosterone can worsen existing OSA; screen for sleep apnea before starting in at-risk patients
Hair thinning / male-pattern baldness
Genetically determinedDHT (dihydrotestosterone, converted from testosterone) drives hair follicle miniaturization in those genetically susceptible
Breast tissue growth (gynecomastia)
3-5%Results from aromatization of testosterone to estradiol; dose reduction or an aromatase inhibitor may help
Serious Adverse Effects
- • Polycythemia (dangerously high red blood cell count), increases stroke and clot risk
- • Cardiovascular events, evidence on long-term risk remains an active area of research; higher risk in older men with pre-existing cardiovascular disease
- • Prostate growth, regular PSA and prostate monitoring required in men
- • Liver toxicity, primarily with oral testosterone (17-alpha alkylated forms); injectable and transdermal largely avoid this
- • Severe acne / cystic acne at high doses
- • Secondary exposure harm to partners and children (with topical formulations)

Special Populations
Safety classifications for specific groups - discuss with your provider before use.
Testosterone causes virilization of a female fetus. Women who are pregnant or may become pregnant must not use testosterone, gel exposure is also a risk for female partners.
Testosterone is not appropriate during breastfeeding.
Testosterone is not FDA-approved for women, but international menopause societies (ISSWSH, IMS) support its off-label use at low physiological doses for hypoactive sexual desire disorder (HSDD) in postmenopausal women. A 2019 Lancet Diabetes & Endocrinology systematic review found benefit for sexual function. Women are prescribed compounded low-dose testosterone creams or gels, at doses approximately 1/10th of male doses. Side effects at these doses are generally mild but include acne and mild hair changes.
The TOM trial in men over 65 was stopped early due to excess cardiovascular events. The TRAVERSE trial in a different older population found non-inferiority for cardiovascular events. Individual risk assessment, particularly cardiovascular history, prostate health, and hematocrit, is essential in older men.
Testosterone may worsen fluid retention in renal impairment. Monitor closely.

Stopping This Medication Safely
Exogenous testosterone suppresses the hypothalamic-pituitary-gonadal (HPG) axis. Stopping abruptly leaves the body without either the exogenous testosterone OR its natural production for weeks to months, causing significant hypogonadism: profound fatigue, low mood, and loss of libido that can persist until the axis recovers. Recovery is not guaranteed in all patients, particularly with long-term use.
What Published Research Shows About Stopping This Medication
This summarizes what published research documents, it is not personal medical advice. Any changes to your medication require discussion with your prescribing physician.
- ·Research documents that abrupt discontinuation causes significant hypogonadism, medical supervision during stopping is consistently supported
- ·Published protocols describe using clomiphene citrate or HCG to stimulate natural testosterone production during the transition
- ·Research supports gradual gel dose reduction over 6-12 weeks; for injections, progressively increasing the interval between doses is documented
- ·Research recommends monitoring morning testosterone levels throughout to assess HPG axis recovery
- ·Research documents full HPG axis recovery typically taking 3-6 months, with longer timelines in patients with years of use
Warning Symptoms, Contact Your Doctor If You Experience:
- Profound fatigue or depressive symptoms within days of stopping
- Severe loss of libido
- Mood changes or irritability
- Morning testosterone level remaining very low at 3-month check
- Testicular pain, potential sign of testicular recovery effort
Never change or stop a medication without consulting your prescribing physician.
