If you have been wondering, “Why is my sex drive gone?” you are not alone—and you are not broken.
Low libido can affect women and men at any age. Sometimes it develops gradually. Other times, it feels as though a switch suddenly flipped. You may still love your partner and want closeness, yet rarely think about sex or feel interested when the opportunity comes up.
Sex drive is influenced by much more than one hormone. Your physical health, medications, sleep, stress level, emotional well-being, relationship, pain, and life stage can all play a role. For many people, several of these factors overlap.
The encouraging news is that low libido often has an identifiable cause—and there may be ways to improve it.
What Is Libido?
Libido is your interest in or desire for sexual activity. There is no single “normal” amount of desire. It naturally varies from one person to another and can change throughout life.
Some people experience spontaneous desire, meaning interest appears before sexual activity begins. Others experience more responsive desire, meaning interest develops after affection, touch, or arousal has started. This can be completely normal, especially in long-term relationships and during busy or stressful stages of life.
Low desire becomes a concern when it represents a change for you, lasts over time, or causes personal distress or problems in your relationship.
Common Causes of Low Libido in Women and Men
- Hormonal changes
Hormones can affect sexual desire, but the answer is rarely as simple as “just balance your hormones.”
In women, changes in estrogen and other hormones during pregnancy, breastfeeding, perimenopause, and menopause may affect desire. Lower estrogen can also contribute to vaginal dryness, irritation, and painful sex. If sex becomes uncomfortable, it makes sense that the brain may become less interested in it.
In men, low testosterone can be associated with reduced sexual desire, fewer spontaneous or morning erections, fatigue, and changes in muscle mass. However, symptoms alone do not prove testosterone deficiency. Medical guidelines recommend diagnosing male hypogonadism only when compatible symptoms occur along with consistently low testosterone levels on properly timed testing.
Thyroid disorders, elevated prolactin, and other hormone-related conditions may also affect libido in women or men.
- Stress and mental overload
It is difficult for the brain to shift into desire when it is stuck in survival mode.
Work pressure, financial worries, parenting, caregiving, an endless mental checklist, and feeling “touched out” can leave little room for sexual interest. Chronic stress may also disrupt sleep and affect mood, creating a cycle that further lowers libido.
- Poor sleep and exhaustion
When you are exhausted, sex often falls to the bottom of the priority list. Insomnia, shift work, young children, and untreated sleep apnea can all contribute.
Sleep apnea deserves special attention—particularly when low libido occurs with loud snoring, witnessed pauses in breathing, morning headaches, or daytime sleepiness. It can affect energy, cardiovascular health, sexual function, and, in some men, testosterone levels.
- Medications
Several medications may affect desire, arousal, orgasm, erections, or comfort during sex. Common examples include some:
- Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs)
- Blood pressure medications
- Hormonal contraceptives
- Opioid pain medications
- Anti-anxiety or sedating medications
- Prostate-related medications
Do not stop a prescribed medication on your own. A clinician can review when your symptoms began, whether they followed a new medication or dose change, and whether a safe alternative or adjustment may be appropriate.
- Depression, anxiety, and body-image concerns
Depression can reduce pleasure and interest in many areas of life, including sex. Anxiety may make it difficult to relax or remain present. Past trauma, fear of pain, performance worries, and changes in body confidence can also affect desire.
Importantly, the condition and its treatment can both matter. For example, depression may lower libido, while certain antidepressants may create additional sexual side effects. That does not mean treatment should be abandoned; it means the whole picture should be considered.
- Pain or sexual-function concerns
Desire often drops when sex is painful, frustrating, or associated with pressure.
For women, vaginal dryness, pelvic-floor dysfunction, endometriosis, infection, vulvar conditions, or genitourinary syndrome of menopause may make sexual activity uncomfortable.
For men, erectile dysfunction, reduced sensation, ejaculation concerns, or fear of losing an erection may lead to avoidance that feels like low desire. Erectile dysfunction and low libido are not the same problem, but they can occur together.
- Relationship and connection factors
Unresolved conflict, lack of emotional safety, unequal responsibilities, poor communication, limited privacy, or feeling pressured can affect sexual interest. This does not mean low libido is “all in your head” or that your relationship is failing. It means desire is both physical and emotional.
- Medical conditions and lifestyle factors
Diabetes, cardiovascular disease, obesity, chronic pain, anemia, neurologic disease, cancer treatment, and other chronic conditions may affect sexual function or energy. Heavy alcohol use, nicotine, recreational substances, limited physical activity, and inadequate nutrition may also contribute.
Low Libido in Women: Is It Perimenopause?
It could be—but perimenopause is only one possibility.
Perimenopause may begin years before the final menstrual period. In addition to changing cycles or hot flashes, women may notice poor sleep, mood changes, brain fog, vaginal dryness, discomfort during sex, and changes in desire.
Still, a hormone level is only one piece of the evaluation. Relationship context, medications, stress, pain, sleep, medical history, and whether the change is personally distressing all matter.
Persistent low desire that causes distress may sometimes meet criteria for a sexual-interest disorder, often discussed as hypoactive sexual desire disorder (HSDD). This is different from simply having less interest than a partner or not wanting sex as often as someone thinks you “should.”
Low Libido in Men: Is It Low Testosterone?
Low testosterone is one possible cause, but it should not be assumed.
For men with symptoms, evaluation generally includes an early-morning total testosterone level. If it is low, testing is typically repeated before making a diagnosis. Depending on the results and situation, free testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin, thyroid testing, and other labs may be considered.
This distinction matters because testosterone therapy is not a universal libido treatment. It is most appropriate for carefully evaluated men who have symptoms and consistently low levels. Testosterone can also suppress sperm production, so future fertility should be discussed before treatment begins.
What Can a Low-Libido Evaluation Include?
A useful evaluation begins with a conversation, not a prescription. Your clinician may ask:
- When did the change begin—suddenly or gradually?
- Is desire low in every situation or only under certain circumstances?
- Is sex painful or physically difficult?
- Have your sleep, stress, mood, health, or relationship changed?
- Did symptoms begin after starting or changing a medication?
- Are you experiencing menstrual changes, hot flashes, vaginal dryness, erectile problems, or fewer morning erections?
- Are you hoping to become pregnant or preserve fertility?
Testing should be individualized. Depending on your symptoms, it may include a complete blood count, metabolic testing, thyroid studies, selected hormone testing, diabetes screening, or evaluation for other health conditions. Not everyone needs every hormone checked, and a single lab value rarely explains the entire problem.
How Is Low Libido Treated?
Treatment depends on what is contributing to it. A personalized plan may involve:
- Treating vaginal dryness, painful sex, erectile dysfunction, or another medical condition
- Improving sleep or evaluating possible sleep apnea
- Reviewing medications with the prescribing clinician
- Addressing depression, anxiety, trauma, or chronic stress
- Pelvic-floor physical therapy when appropriate
- Individual, couples, or sex therapy
- Lifestyle changes that support energy and overall health
- Menopause therapy or other hormone treatment when medically appropriate
- Testosterone therapy for appropriately diagnosed men with hypogonadism
- Selected prescription treatments for certain women with acquired, generalized HSDD
Hormone therapy is not right for everyone, and treatment should never be based on symptoms or a single “optimal” number alone. Benefits, risks, health history, fertility goals, and monitoring all matter.
When Should You Talk to a Healthcare Provider?
Consider scheduling a visit when low libido:
- Is a noticeable change from your usual
- Has continued for several months
- Bothers you or affects your relationship
- Occurs with fatigue, mood changes, menstrual changes, vaginal dryness, painful sex, erectile dysfunction, or fewer morning erections
- Began after a medication change
- Occurs with headaches, vision changes, nipple discharge, testicular changes, pelvic symptoms, or other new concerns
You do not need to wait until the issue becomes severe. Sexual health is part of overall health, and it is reasonable to bring it up.

Frequently Asked Questions About Low Libido
What is the most common cause of low libido?
There is no single most common cause for everyone. Stress, poor sleep, medication effects, depression or anxiety, relationship factors, pain, hormonal changes, and chronic health conditions are all common. More than one factor may be involved.
Can low testosterone cause low libido in men?
Yes, low testosterone can reduce desire in some men. A diagnosis requires both relevant symptoms and consistently low testosterone levels on appropriate testing. One low or improperly timed result is usually not enough.
Can menopause cause low libido in women?
Hormonal changes during perimenopause and menopause may affect desire directly or indirectly through poor sleep, mood changes, vaginal dryness, or pain. However, menopause is not the only possible explanation.
Can antidepressants lower sex drive?
Yes. Some antidepressants can reduce desire, delay orgasm, or affect arousal. Depression itself can also lower libido. Do not stop medication abruptly; discuss symptoms and options with the prescribing clinician.
Does having low libido mean something is wrong with my relationship?
Not necessarily. Libido can change even in a loving, supportive relationship. Physical health, stress, hormones, sleep, medication effects, and life circumstances can all contribute. Relationship factors can matter, but they are only one part of the picture.
Can low libido be treated?
Often, yes. Treatment works best when it addresses the actual cause or combination of causes. Options may include treating pain or a medical condition, reviewing medications, improving sleep, counseling, pelvic-floor therapy, and carefully selected hormonal or nonhormonal treatment.
