Signs You May Need Testosterone Replacement

If you feel unusually tired, struggle to stay focused, or notice that your gym progress has stalled, you may wonder if your hormones are to blame. It's common to dismiss these changes as just a part of getting older, but they're often the body's way of signaling a deficiency.

At Keven Tagdiri, M.D., in Encinitas, California, our team specializes in helping men understand their hormonal health. We know that low testosterone, or low T, affects more than just your energy; it impacts your mood, your heart, and your overall quality of life.

What are the warning signs of low testosterone?

The signs of a testosterone deficiency include a fading sex drive, persistent fatigue, and metabolic changes such as increased belly fat. Because these symptoms often overlap with other health issues, it's important to look at the full picture.

1. Low libido and sexual function

A significant drop in sexual desire or a decrease in morning erections is one of the most reliable indicators that your levels might be low.

1. Ongoing fatigue and brain fog

If you're getting enough sleep but still feel drained or find it hard to concentrate on daily tasks, your hormones may not support your energy needs.

1. Changes in body composition

Testosterone helps maintain muscle mass. When it drops, you might notice you're losing muscle and gaining visceral fat, which is the dangerous fat stored around your midsection.

Is testosterone replacement therapy safe?

For years, many men avoided treatment because of fears regarding heart health. However, the medical landscape changed significantly in early 2025 when the FDA officially removed the "black box" warning regarding cardiovascular risks from testosterone products.

This decision followed the landmark TRAVERSE trial, which monitored over 5,200 men and showed the therapy doesn't increase the risk of heart attacks or strokes when used correctly. Maintaining healthy levels is now seen as supporting long-term heart and metabolic health.

How we diagnose and treat deficiency

We don't guess when it comes to your health. To ensure an accurate diagnosis, we follow the strict standards set by the American Urological Association. They require two separate, fasting morning blood tests that show levels below 300 ng/dL, along with physical symptoms.

Our men's health services focus on a holistic approach. Before starting any medication, we look at your lifestyle. Simple changes, such as losing 15 pounds of belly fat or improving your sleep hygiene, can sometimes boost your natural production by up to 30%.

You don't have to live with the frustrating symptoms of low T. If you're ready to regain your energy and feel like yourself again, we're here to help. Contact our office today to schedule a consultation and take the first step toward balancing your hormones.
