Men and Andropause Age: When Hormonal Shifts Really Begin
Healthy’s Summary
If you’re a guy in your 40s or 50s wondering why your energy’s tanking, your sleep’s gone sideways, and your muscle tone isn’t what it used to be—it could be more than just aging. You might be entering what’s sometimes called andropause: a gradual, hormonally driven transition that’s often misunderstood (and rarely talked about).
So, what is the typical andropause age range in men? While it’s not as clear-cut as menopause is for women, there is a window where testosterone and other hormones start to noticeably decline—and that window starts earlier than you might think.
What Is Andropause?
Let’s clear this up: andropause isn’t a sudden “switch” like menopause. Instead, it’s a slow drip—a gradual decrease in testosterone and other key hormones that can affect energy, mood, strength, sleep, and sexual health. Andropause age isn’t quite as predictable as you might think.
The decline usually begins subtly in a man’s 30s, but most don’t notice significant changes until their early to mid-40s. From there, testosterone levels continue to drop by about 1% per year, on average.
By the time a man reaches his late 40s or 50s, the symptoms can start stacking up: low energy, reduced sex drive, trouble focusing, mood swings, and unexplained weight gain—especially around the belly.
Some experts refer to this as “late-onset hypogonadism” or testosterone deficiency syndrome, but the term “andropause” sticks because it captures the shift so many men feel.

Andropause Age: When Does Andropause Actually Begin?
While every man is different, here’s a general guide based on current research and clinical trends:
- Ages 30–39: Testosterone begins to decline slowly, but most men won’t notice major changes unless they have underlying conditions (like high stress, obesity, or chronic illness).
- Ages 40–49: This is the most common decade when early signs of andropause appear. You may feel more fatigued, have trouble sleeping, or notice your workouts don’t give the same results. Libido might start to dip. Mood and motivation can fluctuate more than they used to.
- Ages 50–60+: For many men, symptoms become more pronounced in this range. If you’ve had a gradual decline over the past decade, this is often when it’s most noticeable. Some may choose to explore medical support like testosterone therapy if lifestyle adjustments aren’t cutting it.
Of course, some men experience few or no symptoms at all. Genetics, diet, exercise, stress levels, and sleep all influence when and how andropause shows up.
What Are the Signs to Watch For?
Even if your testosterone is still in the “normal” range, it might not be optimal for you. That’s why symptom patterns matter just as much as lab numbers.
Men in the andropause age range may experience:
- Slower recovery from exercise
- Lower sex drive or erectile changes
- More belly fat and less muscle mass
- Mental fog or forgetfulness
- Mood changes (irritability, low motivation, feeling “flat”)
- Poor sleep or frequent waking at night
These symptoms can creep in gradually, making them easy to ignore or chalk up to stress or aging. But if you feel like something’s off, it’s worth paying attention.

What Can You Do If You’re In the Andropause Age Range?
The first step is getting tested. A simple blood test measuring total and free testosterone, along with other hormones like DHEA, estradiol, and thyroid markers, can help map out what’s going on. Many men are surprised to learn they’ve been operating with suboptimal levels for years.
Lifestyle changes are the foundation. Prioritize resistance training, eat enough protein and healthy fats, get high-quality sleep, and reduce alcohol and stress where you can. Supplements like vitamin D, zinc, and magnesium may also support hormone balance.
For some men, medically supervised testosterone replacement therapy (TRT) can be life-changing—but it’s not for everyone. It’s best explored when lifestyle changes have been maxed out and symptoms persist. Your doctor will have more specific information about whether or not TRT is right for you.

A Final Thought
Andropause in men doesn’t have a clear starting line—but the age range matters. Most guys start feeling subtle shifts in their 40s, with more noticeable changes in their 50s and beyond. Recognizing the signs early means you can take action sooner—before fatigue, mood swings, and other symptoms disrupt your daily life.
You don’t have to wait until everything falls apart to get support. Understanding your body’s hormonal rhythms is part of living well as you age—and in 2025, there are more options than ever to do just that.
