Why has my sex drive disappeared?
The short answer
Usually because something changed that has nothing to do with wanting your partner. Medication, particularly SSRIs and some hormonal contraceptives, along with depression, exhaustion, chronic pain, thyroid problems and the postpartum period, are all well documented causes. It is also common for desire to be responsive rather than spontaneous, in which case it did not disappear so much as stop arriving unprompted.
What readers think
When your desire dropped, did it turn out to have a physical cause?

The alarming part is usually not the absence itself but the silence around the cause. People notice desire has gone, find no obvious reason, and conclude the relationship must be over or that something is wrong with them. Both conclusions get reached far too quickly. Desire is unusually sensitive to physical health, medication, sleep and mood, and the list of things that reliably suppress it is long enough that a relational explanation should generally be the last one considered rather than the first.
It may not have disappeared, it may have stopped arriving first
An influential model of sexual response proposes that for many people desire is responsive: it emerges after arousal begins and in the right conditions, rather than appearing spontaneously and prompting the encounter[1]. If desire was previously spontaneous and has become responsive, which commonly happens as a relationship moves past its early stage, then nothing is missing except the prompt. Waiting to feel desire before agreeing to anything means waiting for something that now arrives in a different order. This distinction matters practically because it changes what counts as evidence. A person with responsive desire who never encounters an unpressured, unhurried opportunity may accurately report never feeling desire, while retaining the full capacity for it. The model is widely used clinically and has also been criticised as hard to test directly, so it is best treated as a useful framework rather than settled mechanism.
The causes that are actually most common
Antidepressants are among the best documented. Sexual side effects including reduced desire, delayed orgasm and difficulty with arousal are common with SSRIs and SNRIs, affecting a substantial minority of people taking them, and they are frequently under-discussed at the point of prescribing. Some hormonal contraceptives have similar effects for some users. Beyond medication, depression itself reduces desire independently of any treatment, as do thyroid disorders, anaemia, chronic pain, poor sleep and significant stress. The postpartum period involves several of these at once, alongside physical recovery and, where breastfeeding is involved, hormonal changes that directly suppress desire. Pain during sex deserves separate mention, because it is common, frequently normalised, usually treatable, and reliably extinguishes desire when it goes unaddressed.
When it is about the relationship
Sometimes it is. Desire is affected by resentment, by feeling unappreciated, by an unequal division of household and emotional labour, and by a dynamic in which sex has become associated with pressure rather than pleasure. That last pattern is self-reinforcing: a partner who begins to experience every approach as a request they will have to refuse tends to withdraw from touch generally, which reduces the conditions responsive desire depends on, which reduces desire further. The relevant question is not whether the relationship could be a cause but whether the ordinary physical and circumstantial explanations have been examined first. Couples who skip that step often spend a long time working on a relationship that was not the problem.
It depends, on what?
What changes the answer
Low desire is only a clinical problem when it distresses the person who has it. This is the standard the diagnostic manuals use, and it matters, because a good deal of distress about desire is generated by comparison rather than by the level itself. Someone content with infrequent sex whose partner is not content has a relationship problem to solve, not a personal deficit to fix, and the two get conflated constantly. Worth noting separately: some people have consistently low or absent sexual attraction and are not experiencing a loss at all. Asexuality is a recognised orientation rather than a dysfunction, and the distinguishing feature is usually whether this is a change from a previous state or has always been the case.
Where people disagree
Both sides of it
Reasonable people land in different places on this. Here is the strongest version of each case, not a straw man of the one we disagree with.
The case for yes
- Treating lost desire as a medical question first is supported by how frequently medication, illness and sleep turn out to be responsible.
- Many of the common causes are genuinely reversible, including medication changes, treating pain, and addressing depression or a thyroid condition.
- Understanding responsive desire relieves a specific and common form of distress, because it reframes an apparent loss as a change in sequence.
- Examining physical causes first protects the relationship from a blame narrative built on a premise that was never checked.
The case for no
- Framing lost desire as medical can become a way of avoiding real relational problems, including resentment and an unequal domestic load.
- Not every case has a findable cause, and an extended search for one can itself become distressing and reinforce the sense of being broken.
- Medicalising desire risks treating a level of interest as a disorder when it only differs from a partner's, which is a relationship question rather than a diagnosis.
- Waiting for a medical answer can delay conversations a couple needs to have regardless of what the cause turns out to be.
Evidence
What the research says
- Limited evidenceClinically derived model
An influential model of sexual response describes desire as commonly responsive, emerging after arousal and in a receptive context, rather than arising spontaneously and initiating the encounter.
Basson, R., The Female Sexual Response: A Different Model (2000)(opens in a new tab)What this does not show
The model was derived from clinical observation rather than experiment, is widely adopted in practice, and remains difficult to test directly. Empirical support is contested, so it should be treated as a clinically useful framework rather than an established mechanism.
- Strong evidenceMultiple clinical trials and reviews
Sexual dysfunction, including reduced desire, is a common adverse effect of SSRI and SNRI antidepressants, affecting a substantial proportion of people taking them and frequently persisting during treatment.
Higgins, A., Nash, M., & Lynch, A. M., Antidepressant-Associated Sexual Dysfunction: Impact, Effects, and Treatment (2010)(opens in a new tab)What this does not show
Reported rates vary widely across studies depending on whether patients are asked directly or expected to report spontaneously, with direct questioning producing much higher estimates. Distinguishing medication effects from the effects of depression itself is methodologically difficult.
- Moderate evidenceLarge national probability samples
Population surveys of sexual function find low desire is common in both men and women, with prevalence rising with age, and that only a subset of those reporting it also report associated distress.
Shifren, J. L., Monz, B. U., Russo, P. A., Segreti, A., & Johannes, C. B., Sexual Problems and Distress in United States Women: Prevalence and Correlates (2008)(opens in a new tab)What this does not show
Cross-sectional self-report from general population samples, with prevalence estimates sensitive to how questions are worded and over what time period. Surveys establish how common the experience is, not what causes it in any individual.
How we rate evidence strength
- Strong evidence
- Multiple independent studies, including replications or meta-analyses, point the same way.
- Moderate evidence
- Several studies support this, but samples are limited or findings vary by population.
- Limited evidence
- Early, small, or single-study evidence. Treat this as a reasonable hypothesis, not a settled fact.
- Contested
- Credible researchers disagree, or the evidence points in conflicting directions.
Comparative view
Different perspectives
Traditions and disciplines answer this differently. We describe what each one teaches. We are not telling you which is right, and no tradition speaks with a single voice.
Sex Therapist Perspective
Sex therapists commonly describe the pattern in which pressure and desire form a loop: as one partner's concern about frequency grows, touch becomes freighted with expectation, and the lower desire partner withdraws from contact generally, which removes the conditions responsive desire needs. Much clinical work therefore begins by deliberately removing the expectation from physical contact rather than by trying to increase it. Clinicians also report that shame is a substantial part of the presentation, with many people arriving convinced they are broken. This describes prevailing practice rather than a controlled finding.
Medical Perspective
Clinicians assessing low desire generally work through a standard sequence: current medications, mood, sleep, pain, thyroid function, anaemia, and where relevant hormonal status, before considering relational causes. The reasoning is not that relationships rarely matter but that physical causes are common, testable and often treatable, so ruling them out is cheap and skipping them is expensive. Practitioners also emphasise that sexual side effects of antidepressants are widely under-reported unless patients are asked directly, which means the absence of a warning at prescribing is not evidence the medication is not responsible.
Secular Perspective
A secular framing treats desire as a fact about a person at a point in time rather than as an obligation or a moral quality. There is no correct level and no duty to have one. On this view the useful questions are practical: is this a change, does it distress you, does it have a cause you can act on, and can you and a partner reach an arrangement you can both accept. Nothing about a low or absent level of desire requires justification, and framing it as a failure of effort or commitment is not supported by anything the evidence shows.
Christian Perspective
Christian teaching generally treats sexual intimacy in marriage as a good to be cultivated rather than merely permitted, and contemporary pastoral counsellors frequently address low desire as a practical and medical matter alongside a spiritual one. Emphasis differs by denomination and by counsellor, with some placing more weight on mutual obligation and others on patience and shared responsibility for the conditions that make intimacy possible. Presented as that tradition's reasoning rather than as a standard readers are expected to adopt.
Islamic Perspective
Islamic tradition treats sexual intimacy within marriage as a mutual good rather than a burden, and classical texts discuss it in terms of rights held by both spouses. Alongside this, the tradition recognises illness, exhaustion and hardship as circumstances that qualify obligations, and places a general prohibition on causing harm. Many contemporary Muslim counsellors treat a medical cause of low desire as squarely within that recognition and encourage seeking treatment rather than assigning fault. Views vary between scholars and communities; offered as one tradition's reasoning.
Practical steps
What you can actually do
List what changed in the six months before you noticed, including medications, sleep, work, health and family circumstances. The cause is frequently in that list.
Raise medication with your prescriber specifically. Sexual side effects of antidepressants are common, often manageable by changing drug or dose, and frequently not mentioned unless you ask.
Take pain seriously and get it investigated. Pain during sex is common, usually treatable, and reliably destroys desire when it is tolerated rather than addressed.
If desire has become responsive, create conditions rather than waiting for an urge: unhurried time, no expectation of a particular outcome, and touch that is allowed to go nowhere.
Reduce the pressure around initiation before trying to increase frequency. Desire rarely returns in an atmosphere where every approach is a test.
Worth unlearning
Common misconceptions
That losing desire means you have stopped loving or being attracted to your partner. Desire, attraction and love are separate systems and they come apart routinely.
That desire should be spontaneous. For many people it is responsive, arriving after arousal rather than before, and this becomes more common as relationships move past the early stage.
That low desire is a female problem. It is common in men as well, and men are less likely to raise it with a doctor, which makes it look rarer than it is.
That it is only worth investigating if it bothers your partner. The clinical threshold is your own distress, not someone else's disappointment.
That antidepressant side effects are something you simply live with. Dose changes, timing and alternative medications frequently help, and it is a reasonable thing to raise.
The short version
Key takeaways
Medication, especially SSRIs, along with depression, pain, poor sleep and thyroid problems, are common and often reversible causes of lost desire.
Clinical consensusDesire is frequently responsive rather than spontaneous, so an apparent loss may be a change in sequence rather than in capacity.
ResearchLow desire is a clinical concern only when it distresses the person experiencing it, not when it merely differs from a partner's level.
By definitionPressure around initiation suppresses the conditions responsive desire depends on, which makes pushing for frequency counterproductive.
Clinical consensus
Worth saying
When to get professional help
See a doctor if desire dropped noticeably or relatively suddenly, if it began after starting a new medication, or if it comes with pain, fatigue, low mood or other physical symptoms. Ask directly about medication side effects, since alternatives and dose adjustments often exist and prescribers do not always raise the subject. Pain during sex always warrants medical attention and should not be accepted as normal. A sex therapist is appropriate where the physical causes have been examined and the difficulty persists, or where sex has become a source of anxiety. If low desire is accompanied by persistent low mood, loss of interest in other things, or hopelessness, that combination points toward depression and is worth raising with a doctor in its own right.
Still wondering
Related questions people ask
Yes, and this is well documented. Sexual side effects including reduced desire are common with SSRIs and SNRIs. Rates reported in studies rise substantially when patients are asked directly rather than left to raise it themselves. Dose adjustments, timing changes and alternative medications often help, so it is worth discussing with the prescriber rather than assuming it is permanent.
