Low libido: the real causes and what to do

November 9, 2026 · 5 min read

One day the desire went out — no drama, no argument, no explanation. Before you believe love is dying, one question: when libido drops, the couple is almost never the first culprit.

Desire always has a reason

Contrary to popular belief, desire doesn’t just “drop” out of nowhere. It runs into something: a tired body, an overloaded mind, a medication, a hormone, a stage of life. Identifying the what is already half the battle — because most causes can be fixed.

Careful, a passing dip (a few weeks after a birth, a move, a period of overwork) is normal. The warning sign is duration: more than two to three months, and it’s hurting one of you.

The seven most common causes

Physical fatigue — short sleep, shift work, kids: the body always wins.
Stress and mental load — a brain on permanent alert doesn’t manufacture desire (see mental load and desire).
Medications — antidepressants, some blood-pressure pills, hormonal treatments: raise it with your doctor, never stop abruptly.
The contraceptive pill — a debated but real effect for some (see the pill and libido).
Hormonal changes — postpartum, breastfeeding, perimenopause, menopause (see sex after 40).
An unspoken problem — pain during sex, difficulty getting hard, orgasm never reached: the body avoids what hurts.
The relationship itself — unresolved resentment, lack of trust, an argument in progress. The last case is the most treatable — and the most often denied.

What actually helps (and what doesn’t work)

The doctor, first. A blood test and a review of your treatments rule out half the causes in one visit.
Catch up on sleep. Weirdly effective: three good nights often do more than a romantic weekend.
Take the pressure off “performance”. Pleasure with no obligation to deliver sets desire free.
Small daily attentions. Desire is built outside the bed.
NEVER say: “you don’t want me anymore?” — it adds guilt on top of the original cause.

⚠️ “Libido booster” supplements sold online are mostly unproven — and sometimes dangerous. The miracle pill doesn’t exist; the causes, however, all do.

Raising it with them without putting them on the defensive

The partner who lost desire often believes the other has stopped loving them; the one who stays sometimes thinks they’re no longer attractive. Both are wrong, and saying it out loud settles most of it: “it’s not you, I don’t understand what’s happening, let’s figure it out together.”

And if the subject is too charged for two: a sex therapist or your family doctor acts as a translator. Either way, don’t let silence settle in — start by opening the conversation, and know that a temporary gap almost always resolves (see the libido gap).
