It is provided unmodified and as a testosterone ester such as testosterone cypionate, testosterone enanthate, testosterone propionate, or testosterone undecanoate, which act as prodrugs of testosterone. Testosterone has been marketed for use by oral, sublingual, buccal, intranasal, transdermal (patches), topical (gels), intramuscular (injection), and subcutaneous (implant) administration. Alternatively, testosterone products for women are available from compounding pharmacies in the United States, although such products are unregulated and manufacturing quality is not ensured.
It is essential for Androgel users to be vigilant about symptoms that might indicate liver problems. While Androgel can significantly improve quality of life for those with hypogonadism, it is crucial for users to be aware of potential health risks, particularly concerning liver health. Caution and individualized risk–benefit assessment are needed in people with a history of cardiovascular disease, sleep apnea, high hematocrit or prior blood clots, significant liver or kidney impairment, or symptomatic benign prostatic hyperplasia, and in those with strong risk factors for prostate cancer.
Testosterone treatment for reasons other than possible improvement of sexual dysfunction may not be recommended. Decline of testosterone production with age has led to interest in testosterone supplementation. Open communication with healthcare providers can help men make informed decisions about their treatment. Healthcare providers play a pivotal role in managing the health of men on Androgel. Regular exercise and maintaining a healthy weight are also beneficial, as obesity can exacerbate liver conditions. Maintaining a healthy diet, limiting alcohol consumption, and avoiding hepatotoxic medications can all contribute to liver wellness.
The average daily DHTconcentration produced by testosterone gel 100 mg at Day 30 was 555 (± 293)pg/mL and by testosterone gel 50 mg at Day 30 was 346 (± 212) pg/mL. The average daily testosteroneconcentration produced by testosterone gel 100 mg at Day 30 was 612 (± 286)ng/dL and by testosterone gel 50 mg at Day 30 was 365 (± 187) ng/dL. In a single dose, replicate crossover study, when Vogelxo100 mg was applied, absorption of testosterone into the blood continued for theentire 24 hour dosing period. Alcohol-based products, including Vogelxo, are flammable;therefore, patients should be advised to avoid fire, flame or smoking until theVogelxo has dried.
Symptoms of POME include cough, shortness of breath, tightening of the throat, chest pain, sweating, dizziness, and fainting. Injectable forms of testosterone can cause a lung problem called pulmonary oil microembolism (POME). Gynecomastia and breast tenderness may occur with high dosages of testosterone due to peripheral conversion of testosterone by aromatase into excessive amounts of the estrogen estradiol. Exogenous testosterone may cause suppression of spermatogenesis in men, leading to, in some cases, reversible infertility. In February 2025, the US Food and Drug Administration (FDA) specified label changes for products containing testosterone. Another approach being investigated is the detection of the administered form of testosterone, usually an ester, in hair. A number of methods for detecting testosterone use by athletes have been employed, most based on a urine test.
Unlike in Europe, Canada, and much of the rest of the world, oral testosterone undecanoate is not available in the United States. Unmodified testosterone was also formerly available for intramuscular injection but was discontinued. Intramuscular testosterone undecanoate was not introduced in Europe and the United States until much later (in the early to mid 2000s and 2014, respectively). In the 1970s, testosterone undecanoate was introduced for oral use in Europe, although intramuscular testosterone undecanoate had already been in use in China for several years. In the mid-1950s, the longer-acting testosterone esters testosterone enanthate and testosterone cypionate were introduced. This is due to steric hindrance of C17β-position metabolism during the first-pass through the liver.
