Men going through midlife changes often miss the vital link between testosterone, sleep apnea and their overall health. Testosterone levels start to drop naturally after age 40. This creates a range of symptoms that many men brush off as "getting older." This hormonal change—called andropause—affects much of men over age 45-50 and can affect their quality of life by a lot.
The hormonal decline usually happens alongside sleep disorders, especially when you have obstructive sleep apnea (OSA). This creates a dangerous two-way cycle. Untreated sleep apnea leads to disrupted sleep patterns, more night-time waking and less deep sleep. This makes testosterone production worse. Many people think night sweats come only from hormonal changes, but they can actually come from both low testosterone and untreated sleep apnea. British men often ignore these warning signs, not knowing that treating one condition could help improve the other.
Understanding Andropause and Its Overlooked Symptoms

Female menopause happens quickly with sudden hormone changes. Male andropause works differently. Men's hormones decline slowly, starting much earlier in life. Most men go through this change without knowing what it means or how it might affect their health and lifestyle.
What is andropause?
Doctors know andropause as late-onset hypogonadism or age-related testosterone deficiency. This natural decline in testosterone levels starts when men reach their 30s or 40s. Their testosterone drops steadily by about 1% each year [1]. This decline continues throughout life, though middle-aged men notice the effects more.
The media often calls it "male menopause," but medical experts avoid this term. The name suggests a sudden hormone drop like women experience. The process takes much longer [2]. Most men keep their testosterone at normal levels despite this decline. Only 10-25% develop what doctors would call clinically low levels [1].
Testosterone does much more than most people realise. It helps with sexual function, bone strength, muscle growth, fat burning, and many other body functions. When testosterone drops, men might see changes in both their physical and mental health.
Common signs men ignore
Men often brush off andropause symptoms as "just getting older" instead of seeing them as treatable hormone changes [3]. Healthcare providers say men often miss these warning signs:
Physical symptoms:
-
Low energy and tiredness
-
Less muscle and strength
-
More belly fat
-
Poor sleep and insomnia
-
Less stamina
Sexual changes:
-
Lower sex drive
-
Erectile problems, especially in the morning
-
Reduced sexual performance
Emotional and cognitive symptoms:
-
Mood changes and irritability
-
Depression and anxiety
-
Poor focus
-
Memory problems
-
Less motivation and confidence
Three symptoms stand out as red flags: low sex drive, fewer morning erections, and erectile problems [3]. These changes creep up slowly, usually starting between ages 45 and 55. That's why men often blame stress, lifestyle, or ageing [3].
Why it's more than just ageing
Andropause does more than just make you feel older. It can lead to serious health issues that affect how long and well you live. Scientists have found links between low testosterone and heart disease, especially in men who carry extra weight or have type 2 diabetes [2].
Low testosterone speeds up bone loss too. This leads to higher risks of osteoporosis and broken bones [1]. Extra belly fat from low testosterone creates more problems. It raises cholesterol and can cause metabolic syndrome [4].
The link between testosterone and mental health needs special attention. Mood swings, depression, and anxiety aren't just reactions to getting older. These symptoms come directly from changing hormone levels. Many men suffer needlessly because they don't know their symptoms might have hormone-related causes and treatments [5].
Sleep and testosterone create a tough cycle. Sleep apnea can lower testosterone, and low testosterone makes sleep worse. Each problem makes the other one worse [1]. Early detection of andropause becomes vital because it connects with so many other health issues.
Men who see these changes as treatable conditions rather than inevitable ageing can take steps to protect their health, relationships, and quality of life as they age.
Sleep Apnea in Men Over 40: A Growing Concern

OSA is a dangerous condition that often goes undiagnosed in middle-aged and older men. The condition becomes even riskier when combined with hormonal changes during andropause. These health risks are way beyond the reach and influence of just snoring or feeling tired during the day.
What is obstructive sleep apnea (OSA)?
The soft tissues in your throat relax during sleep because of weakened muscles that support your tongue and soft palate. Your airway becomes narrow or closes completely as these muscles relax, which stops your breathing for a moment [6]. These breathing interruptions, called apneas, can happen 5 to 30 times each hour throughout the night [7].
Your blood oxygen levels drop and carbon dioxide builds up during an apnea episode. Your brain notices this problem and wakes you up just enough to breathe again [6]. This survival mechanism keeps you breathing, but this is a big deal as it means that your sleep quality suffers. You can't reach the deep, restorative sleep phases your body needs to stay healthy [8].
Doctors measure OSA severity using the apnea-hypopnea index (AHI), which counts how many times your breathing stops each hour:
-
Mild OSA: 5-14 events per hour
-
Moderate OSA: 15-29 events per hour
-
Severe OSA: 30 or more events per hour [9]
People who don't treat their OSA risk many serious health complications. We noticed cardiovascular problems like high blood pressure, heart attacks, strokes, and irregular heartbeats. More health risks include type 2 diabetes, depression, and chronic lung disease [6].
Prevalence in men aged 60+
Men face a higher risk of sleep apnea as they age. The prevalence of OSA is at least twice as high in people over 65 compared to younger adults, ranging from 13% to 32% [10]. Bixler's research shows that 24% of older men (65-100 years) have OSA, while only 3% of younger men (20-44 years) develop the condition [10].
Sleep apnea becomes even more common in your sixties. Studies indicate that 45% to 65% of men over 60 have OSA [10]. Sleep clinic data shows even higher numbers. A Spanish study found that people 65 and older made up nearly 25% of all sleep clinic studies, and 71.5% of these patients had OSA [11].
Men develop OSA two to three times more often than premenopausal women [7]. In spite of that, women's risk increases after after menopause, which suggests hormones play a protective role [12].
Snoring and hormone levels: the hidden link
The sort of thing I love about sleep apnea research is how snoring connects with hormone levels in both men and women. Studies show that hormonal changes affect your breathing during sleep and your chances of developing OSA [12].
Women's data tells an interesting story. A woman's chance of snoring drops by 19% when her oestrogen levels double, while doubled progesterone levels associate with 9% less snoring [13]. Women who snore show 20% less irregular breathing with higher oestrogen levels [13].
Scientists believe certain types of oestrogen help build respiratory muscles, while progesterone stimulates breathing [13]. In fact, progesterone helps prevent upper airway tissues from relaxing too much during sleep [14].
This connection explains why post-menopausal women on hormone replacement therapy sleep better and have lower OSA rates than those without treatment [14]. Men going through andropause might experience more airway problems during sleep as their testosterone levels drop, creating a two-way relationship between hormone levels and sleep quality.
The Dangerous Connexion Between Low Testosterone and Sleep Apnea
Research shows that sleep apnea and testosterone levels in men have a complex relationship that reinforces each other. This creates a health cycle that can be dangerous and needs attention. The connection becomes even more vital for men going through andropause since both conditions can make each other worse.
How sleep apnea lowers testosterone
Sleep apnea directly affects how much testosterone your body produces through several mechanisms. We found that OSA directly inhibits how the pituitary gland works. It reduces luteinizing hormone (LH) pulse amplitude and decreases mean serum LH concentrations [15]. When the pituitary gland can't properly signal the testes, testosterone production drops.
Disrupted sleep patterns play a significant role in this process. Men who have OSA get less REM sleep, spend less time in deep sleep, wake up more often at night, and don't sleep as efficiently. These factors lead to problems with the pituitary-gonadal system [15]. A study of healthy young men showed that sleeping less than five hours each night for just a week linked to a 10-15% decrease in testosterone levels [16].
The lack of oxygen during sleep, measured by both oxygen desaturation index (ODI) and oxygen nadir, relates strongly to reduced testosterone [17]. Research shows a clear negative relationship between testosterone and AHI (r = -0.409) and ODI (r = -0.458) levels [5]. More breathing interruptions lead to bigger hormonal problems.
How low testosterone worsens sleep apnea
Low testosterone can make sleep apnea worse through several body processes. A study of men over 65 showed that those with lower testosterone didn't sleep as well, woke up more often at night, and spent less time in deep sleep [17].
Testosterone helps keep proper muscle tone, including the muscles in your upper airway. When levels are low, airways can collapse more easily during sleep [18]. Low testosterone also causes central obesity, which increases airway collapse both physically (by compressing the pharynx) and functionally by raising the upper airway's critical closing pressure [18].
Testosterone replacement therapy (TRT) needs careful consideration, even though low testosterone makes sleep apnea worse. TRT might actually trigger or worsen OSA symptoms in some cases [1]. This happens because testosterone affects central breathing control, upper airway muscle tone, and how fluid moves in neck tissues. These changes might increase how often or how severe breathing stops in some people [1].
The bidirectional cycle of OSA testosterone levels
Scientists call this relationship a bidirectional feedback network. OSA reduces testosterone, which then affects breathing control [18]. The cycle keeps going: poor sleep leads to less testosterone, and less testosterone causes poor sleep quality.
Several factors add to this cycle:
-
Chronic lack of oxygen reduces StAR protein in Leydig cells, which blocks testosterone production [18]
-
Inflammatory molecules from OSA can kill testicular cells [18]
-
Broken sleep patterns disrupt melatonin and adrenal gland function [18]
-
Less testosterone leads to more belly fat, which makes OSA worse [15]
You need to tackle both conditions at once to break this cycle. CPAP therapy, the main treatment for OSA, might help boost testosterone levels in some men [16]. Results vary though, and studies disagree about how well CPAP works for low testosterone in men with OSA [5].
Losing weight works well too, since both low testosterone and OSA link to obesity [17]. BMI seems to be the main factor that determines testosterone levels in many men with OSA [2], though there's more to it than just weight.
Understanding how these conditions affect each other gives men with andropause and sleep problems a chance to improve both issues. This could lead to better overall health, more energy, and improved quality of life.
Recognising the Symptoms: When to Take Action

Early detection of andropause and sleep apnea symptoms can prevent serious health issues. Men often brush off these warning signs as normal ageing, but quick intervention can substantially improve their quality of life and stop these conditions from making each other worse.
Daytime fatigue and poor concentration
Excessive daytime sleepiness is a crucial warning sign you should never ignore. Regularly falling asleep during daytime despite long nights of sleep points to serious sleep disruption [19]. This goes beyond normal tiredness—it's a medical condition called hypersomnia that needs attention.
Men with untreated sleep apnea and low testosterone often experience:
-
Problems with focus and concentration
-
Memory issues and decision-making difficulties
-
Reduced work output and more mistakes
-
Low energy and motivation levels
The fatigue from sleep apnea can affect your driving skills similar to alcohol intoxication, which substantially increases accident risks [4]. While insomnia and sleep apnea show different symptoms, both conditions lead to deep fatigue rather than simple tiredness.
Night sweats and disrupted sleep
Night sweats—waking up soaked in sweat—affect nearly one-third of men with obstructive sleep apnea, which is three times more than the general population [20]. Many people blame hormonal changes alone, but these episodes often signal untreated sleep apnea.
Low testosterone levels during andropause can trick the hypothalamus (the brain's temperature control centre) into thinking the body is too hot [21]. This creates worse problems when combined with OSA, since both conditions cause night sweats independently.
Men might dismiss occasional night sweats at first, but ongoing episodes need medical attention, especially with other symptoms like daytime fatigue or mood changes.
Mood swings and reduced libido
Irritable Male Syndrome (IMS) often demonstrates itself during andropause through mood swings from hormonal changes [22]. Men with this condition tend to become:
-
Irritable and impatient
-
Anxious or depressed
-
Withdrawn or argumentative
-
Less interested in sex
These mood changes stem from declining testosterone, rising cortisol (stress hormone), and poor sleep [22]. Understanding how mood changes relate to hormonal shifts matters—these aren't just personality changes but signs of body chemistry at work.
One in five men experience reduced sex drive [23]. This needs medical attention, especially when it comes with erectile dysfunction and other andropause symptoms.
Breathing problems during sleep
Breathing issues during sleep are the clearest signs of OSA that need immediate attention. Your bed partner might notice:
-
Loud, persistent snoring
-
Moments when breathing stops
-
Gasping, snorting, or choking sounds
-
Strange breathing patterns (rapid then shallow, followed by pauses)
These symptoms relate directly to testosterone disruption—worse breathing interruptions lead to bigger hormonal imbalances. The stronger these symptoms get, the more urgent your need for medical help becomes.
Any mix of these symptoms—especially daytime fatigue, night sweats, mood changes, and breathing problems—should prompt a quick visit to your GP. This could prevent sleep apnea and low testosterone from making each other worse. Quick action stops this cycle before serious health complications develop.
Diagnosis and NHS Referral Pathway
The NHS diagnostic pathway helps men with andropause and sleep apnea symptoms get professional help at the time they need it. A GP consultation starts the process that might lead to specialist sleep clinics for a detailed assessment.
When to see your GP
Men need to consult their GP right away if they experience multiple symptoms like daytime fatigue, night sweats, mood changes, or disturbed sleep. A partner or family member's observations about breathing pauses during sleep provide valuable diagnostic information before the appointment [3]. Professional drivers who feel excessive sleepiness should ask their GP to mark the referral as "URGENT." Sleep centres prioritise assessment for people whose jobs involve driving [24].
The GP will typically:
-
Look into your work and personal life to check if stress or anxiety might cause the symptoms [25]
-
Check blood pressure and run blood tests to rule out conditions like hypothyroidism or anaemia [3]
-
Ask you to complete the Epworth Sleepiness Scale questionnaire that measures daytime sleepiness [3]
Hormone testing and sleep studies
After the original consultation, your GP might order morning blood tests to measure testosterone levels because they peak during this time [26]. An endocrinologist (hormone specialist) takes over if the results show testosterone deficiency [25].
A specialist sleep clinic referral comes next if sleep apnea is suspected. NHS sleep services currently have a waiting time of approximately 6 weeks [27]. The sleep assessment includes:
-
Overnight home monitoring with portable equipment that records oxygen levels, breathing movements, heart rate, and body position [3]
-
Polysomnography at a sleep centre measures brain activity, eye movements, muscle activity, and cardiac function throughout the night in complex cases [3]
NHS sleep clinic process explained
NHS sleep clinics only take referrals from GPs and other health professionals - patients cannot refer themselves [6]. GPs must submit all NHS referrals through the NHS e-Referral Service (e-RS) [6].
Sleep clinics have various specialists including sleep consultants, specialist nurses, physiologists, and practitioners who assess patients [27]. The specialists determine sleep apnea severity based on how often breathing stops during sleep (AHI score) [28].
Treatment recommendations vary based on symptom severity. CPAP therapy shows promise in improving testosterone levels for some men with OSA.
Treatment Options: From CPAP to Lifestyle Changes

Sleep apnea and low testosterone treatment works best with an all-encompassing approach. When you manage one condition, it often helps the other. You have several options available that work with varying degrees of success.
CPAP therapy and testosterone recovery
Research hasn't made up its mind about how CPAP affects testosterone levels. Many studies show that CPAP treatment doesn't affect testosterone levels in OSA men, whatever the treatment length [8]. In stark comparison to this, some research suggests total testosterone levels might improve after three months of CPAP therapy, especially when you have severe OSA [29]. CPAP helps most men breathe better at night, but they might need extra help to boost their testosterone levels.
Oral appliances and positional therapy
People who can't use CPAP have other options. Mandibular advancement devices (MADs) pull your lower jaw forward to open up your airway [30]. You can also try tongue-stabilising devices that use suction to keep your tongue in place while you sleep [30]. These custom-fitted devices work best for mild to moderate OSA cases. They help reduce symptoms, make you less sleepy during the day, and cut down on snoring [31].
Weight loss and airway obstruction
Weight loss might be your best bet to tackle both conditions. Losing extra weight cuts down tongue fat by a lot, which relates directly to less severe apnea [32]. Even a small drop in weight reduces fat around your throat and creates more breathing space, particularly behind your soft palate [33]. Your lungs also work better when you shed those extra pounds [11].
Natural remedies to support better sleep
Nature offers several ways to help you sleep better:
-
A glass of warm milk helps because it contains compounds that work like tryptophan in your brain [10]
-
The flavonoids in chamomile tea help you drift off to sleep [10]
-
Your body makes more melatonin when you drink tart cherry juice [10]
Exercise helps you sleep better too. Just remember not to work out too hard right before bed - it heats up your body and releases energising endorphins [10].
Supplements and sleep hygiene tips
Melatonin supplements can help set your sleep schedule straight, but make sure you buy from trusted brands [10]. You might also want to try magnesium, L-theanine, glycine, or valerian [34].
Good sleep habits are crucial too. Keep your bedroom cool - between 65-72 degrees. You should also stay away from bright lights at night. Layered bedding helps you control your temperature while you sleep [10].
Conclusion
The link between andropause and sleep apnea plays a vital role in managing men's health during ageing. These two conditions feed into each other dangerously. They create a cycle that goes beyond simple tiredness or hormone changes and leads to substantial health issues.
Men should pay attention when they experience unexplained daytime sleepiness, night sweats, mood changes, or reduced libido. These symptoms might point to both hormonal decline and sleep-disordered breathing. Many brush these signs off as "just getting older." This mindset lets the harmful cycle continue, but early action can make life much better.
Weight loss emerges as the most powerful way to tackle both conditions at once. A modest drop in weight can substantially reduce airway blockage and help testosterone production naturally. CPAP therapy works great to manage breathing issues, but you might need extra help to deal with low testosterone effectively.
Natural remedies and lifestyle changes work well among other medical treatments. Good sleep habits, managing stress, and specific supplements can help during this life phase. Men who struggle with mood changes should ask their doctors about the testosterone-depression connection.
Getting a diagnosis through the NHS takes determination, but the results are worth it. These connected conditions raise your risk of cardiovascular disease, type 2 diabetes, cognitive decline, and many more serious health issues when left untreated.
British men need to know that treating andropause symptoms and sleep disorders can extend their lives, not just improve them. We can break the cycle between low testosterone and sleep apnea only when we are willing to see how they connect. This helps create complete treatment plans that fit each person's needs. Men can age better with this knowledge instead of accepting unnecessary suffering.
Key Takeaways
Understanding the dangerous connection between andropause and sleep apnea can help UK men break a harmful cycle that affects millions after age 40.
• Andropause and sleep apnea create a bidirectional cycle where each condition worsens the other, affecting 20-30% of men over 45-50.
• Key warning signs include excessive daytime fatigue, night sweats, mood swings, reduced libido, and breathing interruptions during sleep.
• Weight loss represents the most effective intervention for both conditions, significantly reducing airway obstruction whilst naturally supporting testosterone production.
• Men experiencing these symptoms should consult their GP promptly rather than dismissing them as "just getting older" to prevent serious health complications.
• CPAP therapy effectively treats breathing problems but may require additional interventions to address testosterone deficiency and break the harmful cycle.
Left untreated, this dangerous connection increases risks for cardiovascular disease, diabetes, and cognitive decline. Early recognition and comprehensive treatment can dramatically improve quality of life and potentially extend lifespan for men experiencing these interconnected conditions.
FAQs
Q1. How does andropause affect sleep in men? Andropause can contribute to sleep problems in men, particularly sleep apnea. The decline in testosterone levels associated with andropause can lead to increased airway collapsibility during sleep, potentially causing or worsening obstructive sleep apnea.
Q2. What are the key symptoms of andropause that men should watch for? Key symptoms of andropause include mood swings, decreased muscle mass, increased abdominal fat, reduced libido, difficulty sleeping, fatigue, and decreased motivation. Men may also experience hot flushes, reduced bone density, and cognitive changes like poor concentration.
Q3. Can low testosterone levels worsen sleep apnea? Yes, low testosterone can exacerbate sleep apnea. It can lead to increased central obesity and reduced muscle tone in the upper airway, both of which contribute to airway obstruction during sleep. This creates a cycle where sleep apnea further lowers testosterone levels.
Q4. How does sleep apnea impact testosterone production? Sleep apnea can significantly impair testosterone production. The frequent sleep disruptions and oxygen desaturation associated with sleep apnea interfere with the body's natural testosterone production, which primarily occurs during deep sleep cycles.
Q5. What treatment options are available for men experiencing both andropause and sleep apnea? Treatment options may include CPAP therapy for sleep apnea, weight loss programmes, and in some cases, hormone replacement therapy. Lifestyle changes such as improved sleep hygiene, regular exercise, and stress management can also be beneficial. It's important to consult a healthcare professional for a personalised treatment plan.
