Low libido in women — a persistent decrease in sexual desire that causes personal distress — is more common than many people realize. Research suggests that between 10% and 40% of women experience low sexual desire at some point during their lives, making it one of the most prevalent female sexual health concerns 1.
The causes of low libido in women are rarely simple: sexual desire is shaped by a complex interplay of hormonal, psychological, relational, and physical factors that shift across a woman's life span. Hormonal changes during perimenopause, menopause, postpartum recovery, and even the menstrual cycle can all influence desire. Stress, depression, anxiety, relationship dynamics, and body image also play meaningful roles.
Understanding the underlying causes is the first step toward finding an approach that works — whether that involves lifestyle changes, therapy, medical evaluation, or a combination. For supplement options, see our guide to libido supplements for women.
Hormonal Causes of Low Libido in Women
Estrogen and Progesterone Fluctuations
Estrogen supports vaginal lubrication and tissue sensitivity, both of which affect sexual comfort and desire. As estrogen levels decline during perimenopause and menopause, vaginal dryness and discomfort during sex are common — and discomfort is a well-established contributor to reduced sexual interest 2.
See our guide to low estrogen symptoms in women for a full picture of what estrogen deficiency causes. Progesterone fluctuations across the menstrual cycle can also affect mood and desire, with some women noticing lower libido in the luteal phase (the week before menstruation).
Testosterone
Testosterone is often thought of as a male hormone, but women produce it in smaller quantities and it plays a meaningful role in sexual desire. Testosterone levels naturally decline with age and can drop more sharply after surgical menopause (removal of the ovaries).
Some research supports the use of low-dose testosterone therapy in postmenopausal women with hypoactive sexual desire disorder (HSDD), though this use is off-label in most countries and requires medical supervision 1.
Thyroid Dysfunction
Both hypothyroidism and hyperthyroidism can affect libido. Hypothyroidism — an underactive thyroid — is associated with fatigue, depression, and hormonal imbalance, all of which suppress sexual desire. Hyperthyroidism can cause anxiety and mood disruption that similarly impairs interest in sex 2. Thyroid function testing is a standard part of evaluating unexplained low libido.
Postpartum and Breastfeeding
Prolactin — the hormone that drives milk production during breastfeeding — suppresses estrogen and can significantly reduce sexual desire in the postpartum period. Physical recovery from childbirth, sleep deprivation, body image changes, and the psychological adjustments of new parenthood compound hormonal effects. Low libido postpartum is extremely common and typically improves as breastfeeding decreases or ends 1.
Psychological and Emotional Causes
Depression and Anxiety
Depression is one of the most common causes of low libido in women of all ages. The low mood, fatigue, and diminished pleasure associated with depression directly suppress sexual desire. Anxiety — particularly performance anxiety or worry about body image — can similarly inhibit desire by keeping the mind hypervigilant rather than responsive to erotic cues. Treating the underlying mental health condition often improves libido as well 3.
Antidepressant Medications
Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are among the most common causes of medication-induced low libido. These medications raise serotonin levels, which can dampen dopamine pathways involved in sexual motivation and pleasure.
If antidepressant-related sexual side effects are affecting quality of life, a prescribing physician may adjust dosage, switch medications, or add an adjunctive treatment 3.
Stress and Mental Load
Chronic stress elevates cortisol, which suppresses sex hormones and shifts the body into a survival-focused state incompatible with sexual interest. Learning how to lower cortisol naturally may therefore directly benefit sexual desire. Women who carry disproportionate cognitive load — managing household, childcare, and professional demands simultaneously — frequently report this as a central factor in low desire.
Research on the 'mental load' and its relationship to sexual satisfaction supports the idea that equitable relationship dynamics and stress reduction may be meaningful interventions 2.
History of Trauma
Sexual trauma, adverse childhood experiences, and other psychological injuries can profoundly affect sexual desire and response. Trauma responses — including dissociation, hypervigilance, and avoidance — can impair the ability to feel safe and present during intimacy. Trauma-informed therapy is an important part of care for women whose low libido is connected to past experiences.
Physical and Lifestyle Causes
Chronic illness, pain conditions, and certain medications beyond antidepressants can suppress libido. Pain during sex (dyspareunia) from conditions such as endometriosis, vulvodynia, or genitourinary syndrome of menopause (GSM) is a significant and often undertreated driver of avoidance and reduced desire. Cardiovascular conditions and diabetes can affect blood flow to genital tissues, reducing arousal and physical sensation 1.
Alcohol, while often perceived as an aphrodisiac at low doses, is a central nervous system depressant that impairs arousal and orgasm at higher doses. Sleep deprivation reduces testosterone and increases cortisol, creating a hormonal environment hostile to desire.
Relationship Factors
Sexual desire is highly context-dependent. Relationship conflict, poor communication about sexual needs, mismatched desire levels between partners, and emotional disconnection are among the most common contributors to low libido in coupled women.
Research consistently shows that relationship satisfaction and sexual satisfaction are closely linked — interventions that improve relationship quality (including couples therapy and open communication about preferences) often improve libido as well 3.
Evidence-Based Approaches to Low Libido
Medical Evaluation
A healthcare provider can identify and treat hormonal causes through blood testing (FSH, LH, testosterone, thyroid panel, estradiol), rule out medication side effects, and screen for depression or anxiety. For postmenopausal women meeting criteria for HSDD, FDA-approved options include flibanserin (for premenopausal women) and bremelanotide (Vyleesi). Low-dose vaginal estrogen treats GSM-related pain and dryness without significant systemic absorption 1.
Sex Therapy and Couples Therapy
Cognitive behavioral therapy (CBT) and mindfulness-based sex therapy have evidence support for improving sexual desire and satisfaction in women. Sensate focus exercises — a structured approach to physical intimacy that reduces performance pressure — are a common sex therapy intervention. Couples therapy can address relational dynamics that suppress desire 3.
Lifestyle Modifications
Regular aerobic exercise has been shown to improve sexual desire and function in women, likely through effects on mood, body image, cardiovascular health, and hormone levels. Prioritizing sleep, reducing alcohol intake, and addressing chronic stress are foundational.
Research suggests that women who engage in mindfulness practices report higher sexual desire and arousal — mindfulness improves the ability to stay present during sexual activity rather than being distracted by anxiety or self-criticism 2.
When to See a Doctor
Consult a healthcare provider if low libido is causing personal distress or affecting your relationship and quality of life. A doctor can rule out hormonal causes (thyroid dysfunction, estrogen deficiency, testosterone decline), review medications that may be contributing, and screen for depression or anxiety.
If low libido is accompanied by pain during sex, vaginal dryness, or irregular periods, these symptoms also warrant medical evaluation. A referral to a sex therapist or psychologist may be recommended alongside medical care — particularly when psychological or relational factors appear prominent.

Frequently asked questions
What is the most common cause of low libido in women?
There is no single most common cause — low libido in women is almost always multifactorial. Hormonal changes (particularly declining estrogen and testosterone during perimenopause and menopause), stress, depression, relationship dynamics, and medication side effects (especially from SSRIs) are among the most frequently identified contributors. A healthcare provider can help identify which factors are most relevant in your specific situation.
Can low libido be fixed?
In many cases, yes — particularly when a treatable underlying cause is identified, such as a hormonal imbalance, thyroid dysfunction, medication side effect, or depression. Relationship and psychological factors also respond well to therapy. Even when complete restoration of previous desire levels isn't possible (as in natural menopause), evidence-based approaches including hormone therapy, mindfulness, and sex therapy can meaningfully improve sexual satisfaction.
Does low libido in women get better with age?
It varies considerably. Low libido related to postpartum hormonal changes or stress often improves as circumstances change. For some women, libido improves in midlife as relationship comfort deepens and external stressors decrease. However, the hormonal changes of perimenopause and menopause can reduce desire for others — and these women may benefit from medical treatment. The trajectory is highly individual.
Can low testosterone cause low libido in women?
Yes. Testosterone plays a role in female sexual desire, and declining testosterone levels — which occur naturally with age and more sharply after surgical menopause — are associated with reduced desire. Low-dose testosterone therapy has evidence support for postmenopausal women with hypoactive sexual desire disorder (HSDD), though this use is currently off-label in most countries. Discuss with a healthcare provider whether testosterone testing and treatment may be appropriate.
Do antidepressants always cause low libido?
Not always, but SSRIs and SNRIs are among the most common medication causes of reduced sexual desire and arousal in both women and men. The effect varies by individual and by specific medication. Bupropion (Wellbutrin) has a different mechanism and lower rates of sexual side effects, and is sometimes prescribed as an alternative or adjunct specifically to address this issue. Speak with your prescribing physician before making any changes to medication.
