Low energy is a reason to investigate—not a diagnosis
Testosterone replacement therapy treats appropriately diagnosed testosterone deficiency. Diagnosis requires both relevant symptoms or signs and consistently low testosterone levels—not fatigue alone or a single blood test.
Low libido, fewer spontaneous erections, fatigue, and changes in muscle or bone health may occur with testosterone deficiency. These symptoms can also result from poor sleep, medications, depression, obesity, or other health conditions.
A diagnosis generally involves two separate early-morning total testosterone measurements, along with a symptom review. The AUA uses a total testosterone level below 300 ng/dL as a reasonable diagnostic cutoff, but results must be interpreted in clinical context.
Urology Medical Specialists lists low testosterone treatment. Discuss your symptoms and results with Dr. Vendryes to explore evaluation and confirm treatment options appropriate to your health and fertility plans.
Understanding your options
What to know before your consultation
Confirm the cause
Evaluation includes medical history, medications, sleep and other health factors. Additional testing, such as luteinizing hormone or prolactin, may help determine why testosterone is low. Treating contributing conditions can sometimes improve levels or symptoms without TRT.
Consider treatment options
For eligible patients, prescription testosterone may be delivered by gels, injections, or other formulations. The choice depends on your needs, risks, cost, and available products. Not every formulation is offered by every practice. TRT is not intended as a general anti-aging or bodybuilding treatment.
Measure benefit and safety
Follow-up tracks symptoms, testosterone levels, hemoglobin and hematocrit, and blood pressure. Prostate assessment and PSA testing are considered according to age, risk, and clinical guidance. Treatment should be reassessed if levels improve but symptoms do not.
