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

Andropause refers specifically to the gradual, age related decline in testosterone that typically begins in the late 30s to 40s. Because it develops slowly rather than as a single event, symptoms build over years and get dismissed as normal aging or stress. But it is important to understand that not all low testosterone is andropause. Low T is defined by labs and symptoms, not by age.

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 in andropause, 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 protocols that use hCG alongside testosterone to maintain testicular function, or enclomiphene alone (which raises 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.

All three are viable and each has trade-offs. Injectable testosterone (cypionate or enanthate) is the most common and gives the most precise dose control. Transdermal cream or gel is a good option for men who prefer daily application over needles. Pellets are implanted every three to six months and are best for men who want a set-it-and-forget-it approach. NEOS discusses all options and chooses the one that fits your lifestyle and clinical picture.

A comprehensive baseline that includes total testosterone, free testosterone, SHBG, estradiol, PSA, LH, FSH, prolactin, full thyroid panel, CBC, CMP, HbA1c, fasting insulin, full lipid panel, and micronutrient testing. We also assess symptoms with validated screening tools. This is what allows us to make a real diagnosis and design a real protocol, rather than handing out testosterone based on 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.
