Tired all the time
You sleep, you rest, and you still wake up running on empty.

Exhaustion that won’t lift. Less drive. Weight that won’t budge. Strength that isn’t coming back. An endocrinologist can help you understand what may be behind those changes and discuss next steps through telehealth.
Take the 1-minute checkIt’s easy to blame work, stress or getting older. If something has changed and it’s getting in the way of your life, it’s worth bringing up.
You sleep, you rest, and you still wake up running on empty.
You snap faster, forget things and can’t focus like you used to.
Your drive dropped and you shrugged it off as part of getting older.
Getting or keeping an erection has become harder than it used to be.
You watch what you eat and work out, but your weight won’t budge.
Building strength feels harder, recovery takes longer, and everyday activities leave you more wiped out.
What we hear in the exam room
A story from Dr. David’s practice
This patient put a change in his sex drive down to age. His evaluation found very low testosterone. Understanding the cause gave him and his doctor a place to start.
Testosterone levels can change with age. When symptoms are bothering you, an evaluation can help determine whether hormones or something else may be involved.
1-minute check
Five questions to help you put changes into words. This check cannot tell you whether your testosterone is low or whether you need treatment.

Why an endocrinologist
We start by understanding what’s going on with you. That guides which tests and treatments make sense.
Weight & hormones
Extra weight can contribute to lower testosterone. When that is part of the picture, weight care may help improve hormone levels too. We consider both before deciding which treatment makes sense, including GLP-1 medications when appropriate.
With age
If symptoms suggest low testosterone, we look at your history and lab results together. Treatment depends on the cause, your goals and your health.
Sexual health
Hormones are one part of the picture. We can discuss treatments that fit your situation and guide you to a urologist if needed.
Medical conditions
Problems involving the pituitary gland or testicles can affect testosterone. An endocrinologist can evaluate whether an underlying condition needs attention.
How we’re different
We look at your symptoms, health history and goals before discussing treatment. That includes what matters to you about your heart, prostate and fertility.

From home
Some things are easier to talk about one-on-one. Make space for that conversation from a private place that works for you.
Your doctor
Dr. Berger is a former assistant professor at Columbia University Irving Medical Center. He treats men’s hormonal health, weight and metabolic health, thyroid disorders, and conditions involving the pituitary, adrenal glands and bones.
In a private telehealth visit, you’ll tell Dr. Berger what’s changed, review your health history and talk about your goals. If he recommends lab work, he’ll explain what it can help clarify. Together, you’ll decide what makes sense to do next.

Not necessarily. A diagnosis of low testosterone requires symptoms and consistently low levels confirmed with repeat morning blood tests. Your doctor will review the results, discuss possible causes and explain which options fit your health and goals.
Taking testosterone can lower sperm production. If you plan to have children, tell your endocrinologist so you can discuss the options before starting treatment.
