1. What is low libido?

Libido refers to sexual desire — the urge for sexuality and physical closeness. Low libido (reduced libido) is when this desire clearly declines or is entirely absent over a longer period and you suffer as a result. Women and men are affected equally; the topic is far more common than the silence around it suggests.

Importantly: libido is not a fixed quantity. It fluctuates quite naturally throughout life — depending on life stage, relationship, strain, hormone levels and health. Phases with less desire are normal and, on their own, not a sign of illness. Only when the condition persists, causes distress or seriously affects the relationship is it worth taking a closer look.

The key point first There is no "correct" amount of desire — what matters is your own experience and the level of distress. A declining libido is not a personal failing; it almost always has understandable causes: physical, emotional, or ones connected to medications or your life situation.

2. Desire or erection? The important distinction

In men especially, two things are often confused that medically belong clearly apart:

  • Low libido: the desire is missing. Sexual interest is low, thoughts or fantasies fail to appear — regardless of whether an erection would be physically possible.
  • Erectile dysfunction: the desire is there, but the erection does not occur or does not hold. This is about physical function, not about desire. More on this under erectile dysfunction.

The distinction is more than a linguistic nicety: it points to different causes and leads to different solutions. Sometimes both occur together — for example with depression, hormonal disorders or under certain medications. In women, too, a distinction is worthwhile: a lack of desire is different from physical discomfort during sex (such as vaginal dryness during menopause), even though the two can reinforce each other.

Why this matters Describing precisely at the practice whether desire or function is the problem gets you to the right cause faster. Raising both openly is no reason for shame — it is a common, very treatable topic.

3. Causes & triggers

Low libido rarely has just a single cause. Usually several factors work together — physical, emotional and everyday ones. The overview below shows the most common:

  • Stress and exhaustion: constant strain, overwork and lack of sleep often lower desire the most. When you are exhausted, you simply have no energy for desire.
  • Hormonal changes: in women above all the menopause (declining oestrogen), in men a low testosterone level. Pregnancy, breastfeeding and the time after birth also change libido.
  • Psychological strain: depression very often goes hand in hand with a loss of desire — as do anxiety disorders and burnout.
  • Relationship and partnership: unresolved conflicts, a lack of closeness, routine or dissatisfaction within the relationship.
  • Medications: a particularly common and often overlooked trigger — more on this below.
  • Physical illnesses: for example an underactive thyroid, diabetes, cardiovascular diseases or chronic pain.
  • Alcohol and nicotine: regular use can impair desire and sexual function.

Medications as a trigger deserve special attention, because the connection often goes unnoticed. The best known include:

Medication groupExample / note
Antidepressants (SSRIs)e.g. Sertraline — sexual side effects are common
Beta blockerscan affect libido and erection
Hormonal contraceptionthe "pill" can dampen desire in some women
Blood pressure & diuretic medicationscertain active substances affect sexuality
Table scrolls to the right
Important about medications Never stop a medication on your own, even if you suspect it as a trigger. Antidepressants and beta blockers in particular must not be stopped abruptly. Instead, talk to your doctor — there are often alternatives or adjustments.

4. What you should observe yourself

Because low libido has so many possible causes, it helps enormously to put some order into your own situation before you do anything. The following questions often bring clarity in themselves and are ideal for a later conversation with the doctor.

  • Since when? Has desire declined slowly over months or disappeared fairly suddenly?
  • What has changed? New medications, a life event, more stress, menopause, changes in weight or sleep?
  • Desire or function? Is the desire missing — or does the body (erection, arousal, lubrication) not work even though the desire is there?
  • Accompanying symptoms? Are fatigue, low drive, low mood, erectile problems or cycle changes also present?
  • Situation-dependent? Does it affect all situations or only a particular relationship or phase?

A sudden loss of libido that coincides in time with a new medication or with other symptoms is more of a reason for medical assessment than a slow, situation-related fluctuation. Both can be assessed well — the more precisely you observe, the easier it is.

5. When to see a doctor?

Low libido is not an emergency — so you do not have to act immediately. There are, however, situations in which a medical assessment clearly makes sense, both to find the cause and for reassurance.

You should have it medically assessed if the low libido persists for longer and burdens you or the relationship, if it appeared suddenly, or if it coincides with a new medication. The people to turn to are your GP practice, gynaecology, urology or a sexual medicine clinic — there the topic is everyday business.

Have it assessed particularly promptly If the loss of libido appears suddenly and further problems are added — such as erectile problems, marked fatigue or depressive symptoms (low mood, lack of drive and loss of enjoyment). Behind this can lie a treatable hormonal disorder, a depression or another illness. Important: do not stop suspected trigger medications on your own; have the change supervised medically.

6. Diagnosis

The assessment first aims to distinguish physical, emotional and medication-related causes from one another. This often succeeds through the conversation alone — supplemented by a few targeted investigations.

InvestigationWhat it shows
Detailed conversation (medical history)Course, level of distress, relationship, stress, medications, distinction between desire vs. function
Medication checkChecks whether e.g. antidepressants, beta blockers or the pill may be a trigger
Blood test (hormones)Testosterone, thyroid values, if needed oestrogen, prolactin, blood sugar
Physical examinationSigns of an underlying physical illness
Referral if neededGynaecology, urology, sexual medicine or psychotherapeutic assessment
Table scrolls to the right

A well-prepared overview of the course, triggers and medications saves time and makes the conversation easier — especially with a topic that many find uncomfortable.

7. What you can do yourself

  • Tackle stress and exhaustion: enough sleep, breaks and recovery often have a direct effect on desire. Desire needs energy and relaxation.
  • Talk openly: talking with your partner about wishes, closeness and pressure eases tension and can bring desire back.
  • Review medications — but properly: if you suspect a medication as a trigger, raise it at the practice. Do not stop it on your own; there are often alternatives.
  • Mind the basics: exercise, less alcohol and nicotine as well as a healthy weight support your hormone balance and circulation.
  • Take the pressure off: desire cannot be forced. The demand to "have to perform" often makes the problem worse. Phases with less desire are normal.
  • Accept help: for relationship issues, depression or persistent distress, couples or sexual counselling or psychotherapy can be very effective.

FAQ: Common questions about low libido

Yes, desire fluctuates quite naturally throughout life — depending on stress, life stage, relationship and health. Phases with less desire are normal. Only when the condition persists, burdens you or seriously affects the relationship is a closer assessment worthwhile, medically if necessary.
With low libido the desire is missing, that is the sexual urge. With erectile dysfunction the desire is present, but the erection does not occur or does not hold. So one is about desire and the other about physical function. Both can also occur together, but they often have different causes.
Yes, this is a common and often overlooked trigger. SSRI-type antidepressants in particular (e.g. Sertraline), beta blockers and hormonal contraception can dampen desire. But never stop a medication on your own — talk to the practice instead, as there is often an alternative or a dose adjustment.
In some women hormonal contraception (the "pill") can reduce sexual desire, while in others nothing changes. If you notice a link with starting or switching the pill, discuss it at the gynaecology practice — sometimes changing the preparation or using a different contraceptive method helps.
During menopause the oestrogen level falls, which can affect both desire and vaginal lubrication. Depending on the situation, lubricating products, open communication within the relationship and, if appropriate, a discussed hormone therapy can help. What suits you is best clarified at the gynaecology clinic.
Yes. Testosterone plays a role in sexual desire in men and, to a lesser extent, in women too. A low testosterone level can lower desire and is sometimes accompanied by fatigue and low drive. The value can be determined through a blood test and assessed medically.
Very often, in fact. Chronic stress, overwork, lack of sleep and exhaustion are among the most common reasons for declining desire — desire needs energy and relaxation. Depression or an anxiety disorder also strongly dampens libido. Reducing stress, recovery and, if needed, professional support often have a direct effect here.
Low libido is not an emergency. A medical assessment is nonetheless sensible if it persists for longer and burdens you, appears suddenly or coincides with a new medication. You should have it assessed particularly promptly if erectile problems, marked fatigue or depressive symptoms are added as well.
Mind your sleep, recovery and stress reduction, talk openly with your partner and take away the pressure to perform. Less alcohol and nicotine as well as exercise provide additional support. If you suspect a medication as a trigger, discuss it at the practice without stopping it on your own. For persistent distress, sexual or couples counselling helps.
