Somewhere along the way, the switch flipped. Sex used to be something you thought about, wanted, initiated. Now it’s just… not there. Maybe your partner noticed before you did. Maybe you’ve been quietly worried for weeks, wondering if something’s wrong with you — or if you’re broken.

You’re not broken. Desire is not a fixed quantity you either have or don’t. It’s one of the most sensitive systems in the body, and it responds to almost everything — how you sleep, how stressed you are, your mood, your relationship, your health, even the medicines in your cabinet. Before you panic or buy something off Instagram, let’s go through what’s actually going on.

First, an important distinction: this article is about desire — wanting sex — not about erections. Wanting sex but struggling to get or keep an erection is a different problem (erectile difficulties). Low libido is when the wanting itself has faded. The two can overlap, but the causes and fixes aren’t the same.

Libido naturally goes up and down

Here’s the thing nobody tells you: there is no “correct” amount of desire. It’s not a tap that’s supposed to run at a constant rate. It swings — week to week, year to year — based on what’s happening in your life.

A few quiet weeks after a punishing work stretch, a new baby in the house, a family crisis, or just getting older — these are normal dips, not medical problems. The clinical condition doctors actually recognise, hypoactive sexual desire disorder, is rare; it affects only around 1.5% of men. Broader, milder low desire is more common — roughly 15-17% of men report it at some point — but most of it is temporary and tied to something fixable.

So before you treat this as a disease, ask: what changed in your life around the time your desire dropped? That answer is usually the whole story.

The real causes of low libido

Stress and overwork

Chronic stress is probably the single most common libido killer in working men. When you’re under sustained pressure, your body pumps out cortisol, the stress hormone — and cortisol directly suppresses the hypothalamic-pituitary-gonadal axis, the hormonal chain that drives sex drive. Your body is, in effect, deciding this is not the time to reproduce. Deadlines, money worries, long commutes, and a job you dread will flatten desire faster than almost anything.

Poor sleep

This one is underrated. Sleep is when your body does most of its testosterone production. In one controlled study, restricting healthy young men to five hours of sleep a night for a week lowered their daytime testosterone by 10-15% (Leproult & Van Cauter, JAMA 2011 — a small study, but consistent with what’s seen clinically). If you’re running on five hours a night, chronically tired, or have untreated sleep problems, low desire is an expected consequence — not a mystery.

Depression and anxiety

Loss of interest in sex is a hallmark symptom of depression — it can be present in as many as 70% of people with untreated depression (NCBI review). Depression also lowers testosterone, so the two feed each other. If your low libido comes with low mood, loss of interest in things you used to enjoy, poor sleep, or hopelessness, the libido is a symptom — and the depression is what needs treating. Anxiety does similar damage by keeping your nervous system stuck in “threat mode,” where desire simply doesn’t get a turn.

Relationship issues

Desire doesn’t exist in a vacuum. Unresolved resentment, constant fighting, feeling unappreciated, or a long stretch of emotional distance will quietly switch off wanting. This is one of the most common causes and one of the most missed, because men look for a physical explanation when the real issue is what’s happening between two people. If sex has become tense, transactional, or a source of pressure, desire retreats. Often the fix is a conversation, not a pill — start with how to talk to your wife about sex.

Certain medications

A lot of men don’t connect their dropping libido to a tablet they started taking. But some common drugs are well-documented culprits:

  • SSRI antidepressants — these raise serotonin, which can blunt dopamine, the chemical tied to motivation and pleasure. Sexual side effects, including reduced libido, affect a wide range of users (Healthy Male).
  • Some blood-pressure medications (certain beta-blockers and others) can lower desire.
  • A few other drugs, including some used for hair loss and prostate issues, can do the same.

Do not stop a prescribed medicine on your own. If you suspect a drug is the cause, take that to the doctor who prescribed it. There are usually options — adjusting the dose, switching to an alternative with a lower risk of sexual side effects, or changing the timing. Stopping an antidepressant suddenly can be dangerous.

Alcohol and chronic illness

Heavy or regular drinking depresses desire and, over time, lowers testosterone. Chronic conditions — diabetes, thyroid problems, kidney or liver disease, obesity — all interfere with the hormonal and vascular systems behind libido. If you have an ongoing health condition, low desire may be part of the picture, and managing the condition better often helps.

Low testosterone

Yes, low testosterone can reduce libido — but it’s rarely the only sign. Low T typically shows up as low desire plus a cluster of other symptoms: persistent fatigue, loss of morning erections, low mood, difficulty concentrating, loss of muscle. If that whole pattern fits you, it’s worth checking — but desire alone is a weak signal, and most men with low libido do not have a testosterone problem. More on the symptoms of low testosterone and how testosterone testing works in India.

Some men report that heavy porn use reshapes what their arousal responds to, so a real partner stops registering the same way. The evidence here is mixed and largely correlational — reviews have not established that porn use causes lower desire, and the link may run both ways (NCBI review). Still, for men who suspect it, cutting back is low-risk and some find their desire for real intimacy returns.

”I want it less than my partner” — that’s not a disorder

A lot of men land here not because their desire vanished, but because it’s lower than their partner’s, and that gap has become a source of stress.

This is called desire discrepancy, and it is one of the most normal things in long-term relationships. Two people almost never want sex at exactly the same frequency. And it isn’t always the man who wants more — research on couples consistently finds men are just as likely as women to be the lower-desire partner. A mismatch is a couple’s thing to navigate together, not evidence that something is medically wrong with either of you. Treating it as a defect to be fixed usually makes it worse; treating it as a conversation usually helps.

When low libido is worth getting checked

Most dips resolve on their own once the cause — stress, sleep, a rough patch — eases. See a doctor when:

  • The drop is persistent (months, not weeks) and is genuinely bothering you.
  • It comes with other symptoms: fatigue, low mood, loss of morning erections, unexplained weight changes, or hopelessness.
  • It started soon after a new medication.
  • There are signs of depression — in which case, treating the mood is the priority.

A doctor will take a proper history, look at your medications, and where the pattern fits, may order a morning blood test for total testosterone (levels are highest in the morning, and one low reading isn’t enough — it’s confirmed on two separate morning tests). Doctors generally treat below 300 ng/dL alongside symptoms as low (American Urological Association) — never the number in isolation. (Indian labs may report in nmol/L; roughly 12 nmol/L ≈ 346 ng/dL — European guidelines use that slightly higher cut-off. The exact number matters less than the pattern: a low reading plus symptoms, confirmed on a repeat morning test.) A GP, a urologist/andrologist, or an endocrinologist can all help; if mood is the main issue, a psychiatrist or counsellor is the right call.

Skip the “libido boosters”

You’ve probably already seen the ads — herbal capsules, “mardana taqat” oils, shilajit blends, online powders all promising to fire your drive back up. Here’s the straight version: there is no credible evidence that any of these fixes low libido. Worse, some have been found adulterated with undisclosed prescription drugs, which carry real risks. They don’t touch the actual causes — your sleep, your stress, your mood, your medication, your hormones — so at best they waste your money and at worst they harm you.

The honest path is less glamorous and far more effective: figure out why your desire dropped, and address that. Sleep more. Get the stress under control. Cut back on alcohol. Have the hard conversation with your partner. Get your mood checked. Review your medications with your doctor. That’s what actually moves the needle.

The bottom line

Low libido is usually a signal, not a sentence. It’s your body telling you something is off — too little sleep, too much stress, a low mood, a medication, a strained relationship — far more often than it’s telling you something is permanently wrong. Desire naturally rises and falls, and wanting sex less often than your partner is normal, not a disorder. When the drop is persistent and comes with other symptoms, get it checked properly rather than guessing or self-medicating. The fix is almost never a bottle off the internet — it’s finding the real reason.
