Men's hormone health
Testosterone Therapy for Low T
Fatigue, low drive, brain fog, and lost strength can signal Low T. Accurate testing and personalized therapy can help you feel like yourself again.
Quick answer
Testosterone levels naturally decline after about age 30, and low testosterone ('Low T') can cause fatigue, reduced libido, mood changes, and loss of muscle. Lief Urology diagnoses Low T with proper blood testing and treats it with personalized testosterone replacement therapy (TRT) — delivered by injection, gel, or pellet and carefully monitored.

What is Low T?
Testosterone is the hormone behind energy, libido, mood, focus, and muscle. After roughly age 30 it begins a slow decline, and for some men it drops far enough to cause real symptoms — a condition called testosterone deficiency, or "Low T." It's common, and it's very treatable.
Could this be you?
- Persistent fatigue or low energy
- Reduced sex drive or erectile difficulty
- Mood changes, irritability, or "brain fog"
- Loss of muscle, increased body fat
Personalized, monitored treatment
Dr. Lief — who has lectured on hypogonadism and male menopause — starts with proper blood testing to confirm the diagnosis, not guesswork. If TRT is right for you, he'll tailor the delivery method (injections, gels, or pellets) to your lifestyle and monitor your levels over time to keep therapy safe and effective. Because Low T and erectile dysfunction often overlap, the two are frequently evaluated together. Dr. Lief is also an active clinical researcher in low-testosterone treatment.
