Is 'manopause' real? Doctors explain why some men experience hormonal changes after 40

Men don't wake up one day and suddenly stop producing hormones the way women experience menopause. Yet many men in their 40s and 50s begin noticing something is different. They feel constantly tired despite getting enough sleep. They gain weight around the abdomen. Their sex drive drops, workouts become harder and mood swings become more frequent.

Popularly, this phase has come to be known as "manopause" or male menopause and is also sometimes referred to as "andropause." But is it a real medical condition? Doctors say yes and no.

While men do experience age-related hormonal changes, the term male menopause isn't medically accurate. The condition is actually known as late-onset hypogonadism (LOH) or age-related testosterone deficiency, where testosterone levels fall below normal and are accompanied by persistent symptoms.

So, what exactly is 'manopause'?

"When we hear the word menopause, we immediately think of women. But men too can experience age-related hormonal changes that affect their physical, emotional and sexual health," says Dr. Prathima A, Consultant- Obstetrics, Gynaecology and Urogynaecology, Motherhood Hospitals, Banashankari, Bengaluru.

She explains that unlike women, who experience a relatively abrupt decline in reproductive hormones, men do not undergo a sudden hormonal shutdown. Instead, testosterone, the body's primary male sex hormone, gradually declines by about one to two per cent every year after the age of 30 to 40.

"For many men this decline is mild and causes little concern. For others, it can significantly affect quality of life, relationships and overall health," she says.

Echoing the same, Dr. Gokulakrishnan P J, Lead Consultant and Head of Urology at Aster Whitefield Hospitals, says the correct medical term is late-onset hypogonadism, which is diagnosed only when low testosterone levels are confirmed through blood tests alongside characteristic symptoms.

What are the symptoms?

Because testosterone influences much more than sexual health, its decline can affect several aspects of daily life. According to Dr. Prathima, symptoms usually appear gradually and are therefore easy to dismiss as "just getting older."

Some of the most common signs include:

-Persistent fatigue despite adequate rest

-Reduced sexual desire or libido

-Erectile difficulties

-Loss of muscle strength and increasing abdominal fat

-Unexplained weight gain

-Reduced stamina

-Poor sleep

-Irritability, anxiety or low mood

-Difficulty concentrating and forgetfulness

-Loss of enthusiasm for activities once enjoyed

Dr. Gokulakrishnan adds that untreated testosterone deficiency may also contribute to reduced bone density, increasing the risk of osteoporosis later in life.

Who is most at risk?

Age is only one part of the picture. Doctors say obesity, diabetes, high blood pressure, high cholesterol, chronic kidney disease, sleep apnoea, smoking, excessive alcohol intake and prolonged stress can all accelerate testosterone decline.

Modern lifestyles don't help either. "Inadequate sleep and prolonged work stress have become important contributors," says Dr. Prathima.

Does every tired man have low testosterone?

Not at all. One of the biggest misconceptions, according to Dr. Prathima, is that every middle-aged man with low energy needs testosterone injections.

"A diagnosis requires both characteristic symptoms and laboratory confirmation of low testosterone levels," she explains.

Doctors usually recommend an early morning blood test between 7 am and 10 am, when testosterone levels are naturally highest. If results are low, they are generally repeated before confirming the diagnosis. Additional investigations may also be needed to rule out thyroid disorders, diabetes, vitamin deficiencies and other medical conditions that can produce similar symptoms.

Can it be treated?

In many cases, yes, but treatment doesn't begin with injections. "There is no magic injection that replaces healthy living," says Dr. Prathima.

The first line of management includes strength training, maintaining a healthy body weight, eating a balanced protein-rich diet, improving sleep quality, managing stress, quitting smoking and limiting alcohol.

Even modest weight loss in overweight men can naturally improve testosterone levels. If symptoms persist and repeated blood tests confirm testosterone deficiency, doctors may recommend testosterone replacement therapy (TRT) in the form of gels, injections or other approved formulations.

However, Dr. Prathima cautions that testosterone therapy is not an anti-ageing treatment and should never be taken without medical supervision. It is also unsuitable for some men, including those with prostate cancer or untreated severe sleep apnoea, and can suppress sperm production, making it an important consideration for men planning to have children.

When should you see a doctor?

Experts say it's worth seeking medical advice if symptoms such as fatigue, declining libido, erectile dysfunction, mood changes, increasing abdominal obesity or loss of muscle strength persist for several months and begin affecting quality of life.

"Aging is inevitable, but suffering in silence is not," says Dr. Prathima.

"Male menopause is not about losing masculinity. It is about recognising that health evolves with age, and effective treatments are available when needed."

The takeaway is simple: while "manopause" may be a popular label, persistent hormonal symptoms shouldn't be dismissed as a normal part of ageing. With proper evaluation, many men can address the underlying cause and improve both their physical and emotional well-being.
