What's actually happening to your hormones in your 30s

What some men notice in their 30s

Many men assume hormones only become something to think about in their 40s or 50s. In practice, your 30s are often when men first start asking questions, usually because something feels a little different, even if it is hard to put a finger on. This guide does not try to explain what is going on inside your body; that is a conversation for your GP. What it does is describe the kinds of things men in this decade commonly mention, the everyday habits worth trying, and how to make the most of an appointment if you decide to book one.

Your 30s are often a full decade. Careers are building, money can feel tight, and many men are raising young children or caring for others, sometimes all at once. Sleep gets squeezed, exercise slips, and evenings blur into work or screens. Against this backdrop, some men notice small changes in energy, mood, sleep or drive creeping in gradually, and they are easy to put down to being busy. Sometimes that is the whole story, and sometimes it is worth a closer look.

Fertility is also on the mind for many men in this decade, whether they are trying to have children now or thinking about it for later. If that applies to you, it is a perfectly reasonable thing to raise with your GP, even if nothing feels wrong.

Signs worth paying attention to

None of the following means something is wrong on its own. They are simply things some men in their 30s mention, and worth noting down if they keep coming up.

Energy that dips despite otherwise looking fine

Some men notice a subtle drop in their usual energy. Not exhaustion, just a sense that their get-up-and-go is not quite what it was in their 20s. It is easy to put this down to a busier life, and often that is part of it. If it carries on for weeks or starts to affect work or home life, it is worth mentioning to your GP.

Recovery taking longer

If you train or play sport, you may find you feel stiffer or more tired for longer after a session than you used to. Many men notice this and simply adjust, but if it comes alongside other changes on this list, it is worth noting down.

Stress that does not switch off

Feeling permanently "on", struggling to relax even during downtime, or lying awake with your mind racing are things a lot of men in their 30s describe. This is worth paying attention to in its own right. If it is affecting your sleep, mood or relationships, your GP is a good place to start, and talking it through with someone you trust is worth doing too.

Sleep that does not feel refreshing

Some men find they wake up tired despite spending enough time in bed, or that their sleep has become lighter or more broken. Loud snoring, waking often in the night or feeling sleepy during the day are all worth mentioning to your GP rather than simply pushing through.

Reduced libido or changes in sexual function

A dip in sex drive in your 30s is often put down to stress, tiredness or a long-term relationship settling into a routine, and sometimes that is exactly what it is. If you notice a change that lasts, or any difficulty getting or keeping an erection, it is worth raising with your GP rather than assuming it is all in your head. It is a common conversation for them, and nothing to feel awkward about.

Fertility concerns

If you and a partner have been trying to conceive without success, or you are simply curious about your own fertility, your GP can talk through what checks might be appropriate for you both. It is worth going together if you can, and worth mentioning anything relevant, such as past illnesses or operations, any medicines you take, and how much you drink or smoke.

Changes in body composition

Some men find it a little easier to gain weight around the middle and a little harder to build or keep muscle, despite training and eating much as they did in their 20s. Often this happens so gradually that it never feels like a single change. If it bothers you, or comes with other changes on this list, it is a reasonable thing to mention to your GP.

Asking about blood tests

If you are curious about your hormones or several of the changes above sound familiar, your GP can talk through whether a blood test is appropriate for you, which tests to consider and what the results mean in your particular case. Results are best read alongside your symptoms, your history and anything else you take, so it is worth going through them with a professional rather than interpreting numbers on your own.

Before the appointment, it is worth noting down what you have noticed, when it started, how often it happens, what seems to make it better or worse, and everything you take, including medicines, vitamins, supplements and herbal products. If fertility is a concern, mention that too, as your GP may suggest different checks.

Everyday habits worth trying

None of the following is a treatment, and none of it replaces advice from your GP. These are simply everyday habits many people find worth trying, and your 30s are a good time to make them part of normal life.

A regular sleep routine

Going to bed and getting up at roughly the same time each day, keeping the bedroom cool, dark and quiet, and putting screens away a little before bed are all worth trying. If work or young children make this hard, even a couple of earlier nights a week is a reasonable place to start.

Movement and strength work

Regular movement is worth building into your week, ideally including some strength work a couple of times a week alongside walking, cycling or whatever activity you enjoy. Start at a level that feels manageable and build up gradually. If you have a health condition or have not exercised for a while, check with your GP first.

Making time to switch off

This does not need to be elaborate. Time outdoors, a regular walk, keeping part of the day free from work and screens, and spending time with friends and family are all worth trying. If stress is feeling hard to manage, talk to your GP, who can tell you what help is available.

Keeping alcohol modest

It is worth being honest with yourself about how much you drink, including the quiet regular evenings as well as the big nights out. Keeping alcohol modest, having several alcohol-free days each week, and not drinking close to bedtime are all worth trying. If you are trying to have children, it is worth asking your GP about alcohol too.

Small habits, kept up

Your 30s are often when the routines that carry through the rest of your life get set. Regular meals with plenty of vegetables and protein, a steady sleep routine, regular movement and modest drinking are not dramatic changes, but they are worth building in now while life is busy, rather than waiting for a quieter moment that may never come.

If you are thinking about supplements

Read the label carefully. Look at the amount in each daily serving and the percentage of the reference intake it provides, and check whether more than one product you take contains the same ingredient, so you are not doubling up without realising. Tell your pharmacist or GP everything you take, including vitamins, minerals and herbal products, particularly if you also take a prescribed medicine. In Great Britain, companies may only describe what a nutrient does using wording from the official register of authorised health claims, so be wary of any product that promises more than that. Supplements are not a replacement for a varied diet.

When to see your GP

• If you notice several of the changes above together, rather than just one on its own
• If you have had a blood test and are unsure what the results mean for you
• If you and a partner have been trying to conceive for a year or so without success
• If you have erection problems, which are worth raising with your GP, who may also want to check your heart health
• If tiredness, low mood or reduced drive are getting in the way of day-to-day life
• If you take a prescribed medicine and are thinking about adding a supplement (your pharmacist is also a good person to ask)

None of this is meant to suggest something is wrong. Plenty of men notice small changes in their 30s, and talking them through with your GP or pharmacist is a sensible, ordinary thing to do. If you ever feel low, hopeless or unable to cope, speak to your GP promptly or contact the NHS for urgent advice.
