You do not have to feel this way. Low testosterone is treatable.

No. Low testosterone is defined by your labs and symptoms, not your age. The gradual, age related decline that typically begins in the late 30s to 40s is sometimes called andropause, but it is only one cause. Sleep apnea, insulin resistance, stress, thyroid issues, nutrient deficiencies, and medications can all lower testosterone at any age, which is why NEOS looks for the underlying cause.

Yes. Low testosterone can occur at any age and is increasingly common in men in their 20s and 30s. A 25 year old with fatigue, low libido, weight gain, and low testosterone labs is not experiencing age related decline, but he does have low T that needs to be investigated. In younger men the underlying causes are frequently reversible: sleep apnea, obesity, insulin resistance, chronic stress, thyroid dysfunction, nutrient deficiencies, or medication effects. Less commonly, pituitary problems or genetic conditions are involved. Age is not required for low T, and low T at any age warrants a real workup.

Common symptoms include fatigue that does not improve with rest, low libido, weak or absent morning erections, erectile dysfunction, weight gain (particularly around the midsection), loss of muscle mass and strength, brain fog and poor focus, low mood or depression, irritability, poor sleep, and a general loss of motivation and drive. Symptoms often build gradually over years.

Many things can cause low T: sleep apnea (one of the most common and dangerous if left untreated), metabolic syndrome and insulin resistance, obesity, thyroid dysfunction, chronic stress and HPA axis disruption, nutrient deficiencies (zinc, vitamin D, magnesium), certain medications (opioids, corticosteroids, some antidepressants), excessive alcohol use, and less commonly pituitary problems or genetic conditions like hemochromatosis. This matters because some of these causes, if left unaddressed, can lead to serious illness including hypertension, type 2 diabetes, heart failure, and stroke. NEOS investigates the root cause of your low T rather than just replacing the hormone.

Testosterone replacement therapy is well established with decades of evidence supporting its safety when properly monitored. What is unsafe is prescribing testosterone without labs, without follow-up, and without watching for the small number of things TRT can affect over time (red blood cell count, prostate markers, estradiol conversion). NEOS monitors all of these routinely.

Traditional testosterone therapy alone can suppress natural testosterone production and reduce sperm production. For men who want to preserve fertility, NEOS offers approaches designed to help maintain testicular function and sperm production, including options that raise your own testosterone without suppressing fertility. We discuss fertility goals upfront and design your protocol accordingly.

Yes. PSA and prostate health are checked at baseline and monitored routinely while you are on testosterone therapy. Current evidence does not support the older concern that TRT causes prostate cancer, but PSA monitoring remains a standard part of responsible TRT care.

Yes. Testosterone can be delivered in several ways, and each one differs in dose control, convenience, and how steady your levels stay. NEOS reviews the options with you and recommends the one that fits your lifestyle and clinical picture.

A comprehensive baseline tailored to you. It typically includes testosterone and related hormones, prostate screening, a full thyroid panel, a blood count and metabolic panel, blood sugar and lipid markers, and micronutrient testing. We also use validated symptom questionnaires. The exact labs vary from patient to patient based on your history and goals, so we can make a real diagnosis instead of treating one number.

Yes, as add-on testing when clinically indicated. DUTCH testing (Dried Urine Test for Comprehensive Hormones) shows how your body is metabolizing testosterone, estrogen, and cortisol across the day. It is helpful for men whose symptoms do not fully resolve on standard TRT or who have complex hormonal patterns. Four-point salivary cortisol testing evaluates HPA axis function and is helpful for chronic stress, unexplained fatigue, and burnout. Semen analysis is available for men focused on fertility preservation.
