Low sex drive is one of the most common sexual health complaints, and it rarely has a single cause. The good news is that most of the factors behind it are modifiable. Whether the drop happened gradually or suddenly, the path back typically involves addressing a combination of physical health, hormonal balance, mental well-being, and relationship dynamics.
Check Your Medications First
If your libido disappeared around the time you started a new medication, that’s probably not a coincidence. Antidepressants, especially SSRIs and SNRIs, are among the most common culprits. Drugs like escitalopram, citalopram, paroxetine, sertraline, and fluoxetine account for the majority of reported cases of medication-related sexual dysfunction. The effects can include reduced desire, difficulty with arousal, and trouble reaching orgasm.
These side effects are significantly underreported, meaning many people assume their low libido is “just them” when it’s actually a predictable drug effect. Birth control pills, blood pressure medications, and antihistamines can also dampen desire. If you suspect a medication is involved, talk to your prescriber about alternatives or dosage adjustments. In many cases, switching to a different drug in the same class can make a meaningful difference. Don’t stop any medication on your own.
Exercise Does More Than You Think
Regular physical activity is one of the most reliable ways to increase sexual desire, and the reasons go beyond “getting in shape.” Exercise changes your hormonal environment, improves blood flow to sexual organs, lifts mood, and reshapes how you see your own body. All of these feed directly into desire.
The type of exercise matters. Combining strength training with cardio appears to have the strongest effect. In one study of women experiencing antidepressant-related sexual dysfunction, a routine of 30 minutes of mixed strength and cardio exercise three times per week improved both sexual desire and overall sexual function. The key was maintaining a moderate-to-high intensity, around 70 to 85 percent of maximum heart rate.
Body image plays a surprisingly large role in libido, and exercise improves it. The effect is strongest when people combine aerobic and resistance training at a challenging intensity. Mild exercise barely moves the needle on body image, while strenuous exercise produces a meaningfully larger effect. Moderate-to-vigorous aerobic exercise also shifts estrogen metabolism in ways that support sexual health, with changes documented after about 16 weeks of consistent effort at 150 minutes per week.
Sleep and Stress Are Quietly Sabotaging You
Chronic stress floods your body with cortisol, a hormone that directly competes with the hormonal pathways responsible for sexual desire. Moderate-to-high-intensity exercise actually raises cortisol temporarily, but low-intensity movement (a walk, gentle yoga) lowers it. If your life is already high-stress, layering in some calm physical activity can help more than another intense gym session.
Sleep deprivation has a more nuanced relationship with libido than many articles suggest. A meta-analysis of studies on men found that short-term partial sleep restriction (a few nights of five or six hours) didn’t significantly reduce testosterone levels. However, total sleep deprivation of 24 hours or more did cause a measurable drop. The practical takeaway: one bad night won’t tank your sex drive, but chronically poor sleep creates a hormonal and emotional environment where desire struggles to thrive. Fatigue alone makes sex feel like one more chore on the list rather than something appealing.
Hormonal Changes, Especially During Menopause
For women approaching or going through menopause, falling estrogen levels are often the central issue. Lower estrogen reduces desire directly and also causes vaginal dryness, which can make sex uncomfortable or painful. When sex hurts, your brain learns to avoid it, and desire drops further in a self-reinforcing cycle.
Addressing the physical discomfort is often the first step. Over-the-counter lubricants help in the short term, while vaginal moisturizers used regularly can improve tissue health over time. For more significant symptoms, localized estrogen therapy (applied directly to vaginal tissue rather than taken systemically) is effective for many women. Plenty of women maintain satisfying sex lives through and after menopause, but it sometimes requires being more intentional about addressing these changes rather than waiting for things to resolve on their own.
For men, testosterone levels decline gradually with age, typically about one percent per year after 30. If you’re experiencing low desire along with fatigue, reduced muscle mass, and mood changes, a blood test can determine whether low testosterone is a factor. Testosterone replacement therapy is an option, but it carries trade-offs that are worth discussing with a doctor.
Zinc and Nutritional Gaps
Zinc plays a direct role in testosterone production. In a controlled study, young men placed on a low-zinc diet for 20 weeks experienced a testosterone drop of nearly 75 percent. That’s an extreme scenario, but milder deficiencies are common, particularly in vegetarians, older adults, and people with digestive conditions that reduce nutrient absorption.
Zinc also supports your sense of smell, which has a surprising connection to sexual arousal, especially in younger men. Subtle chemical signals that trigger attraction depend partly on a functioning sense of smell, and zinc deficiency can blunt that. Good dietary sources include oysters, red meat, poultry, beans, nuts, and fortified cereals. If you suspect a deficiency, a simple blood test can confirm it, and supplementation at moderate doses (15 to 30 mg daily) is generally safe.
Reconnecting With Your Partner
Desire doesn’t exist in a vacuum. Relationship tension, poor communication about sex, and the monotony of long-term partnerships all erode libido over time. One of the most effective therapeutic approaches is called sensate focus, a structured series of touching exercises developed for couples. The idea is to remove the pressure of “performing” and rebuild physical intimacy from the ground up, starting with non-sexual touch and gradually progressing. Stanford Medicine describes it as very effective for desire, arousal, and orgasmic difficulties.
The exercises work by breaking the anxiety cycle that often surrounds sex in couples where one or both partners have lost desire. When sex becomes associated with pressure, guilt, or fear of disappointing your partner, avoidance feels safer than trying. Sensate focus retrains your brain to associate touch with pleasure and connection rather than obligation. Many sex therapists use it as a cornerstone of treatment, and some couples find they can work through the exercises on their own using guided resources.
Prescription Options for Women
Two FDA-approved medications exist specifically for low sexual desire in premenopausal women. The first, flibanserin (sold as Addyi), is a daily pill that works on brain chemistry rather than hormones. In clinical trials, women taking it gained roughly 0.6 to 1.0 additional satisfying sexual events per month compared to placebo, and desire scores improved modestly. The effects are real but not dramatic, and they come with notable side effects: about 11 percent of women experience dizziness, 11 percent experience drowsiness, and 10 percent report nausea. Around 13 percent of women in trials stopped taking it because of side effects, compared to 6 percent on placebo.
The second option, bremelanotide, is a self-administered injection used as needed before sexual activity rather than taken daily. Both medications require a prescription and a formal diagnosis of hypoactive sexual desire disorder. They are not approved for men or for postmenopausal women.
Supplements: Limited Evidence
Maca root is the supplement most commonly marketed for libido. While some small studies have suggested a benefit at doses around 3 grams per day, the evidence base is thin. A clinical trial attempting to study maca in women with medication-related sexual dysfunction was terminated after enrolling only 8 participants, too few to draw any conclusions. Other commonly promoted supplements like ashwagandha, fenugreek, and tribulus have similarly limited or mixed evidence. None have been shown to produce effects comparable to addressing the underlying causes listed above.
If you want to try a supplement, maca and ashwagandha have reasonable safety profiles at standard doses. Just keep your expectations modest, and treat them as one small piece of a larger strategy rather than a solution on their own.
Building a Practical Plan
Low libido is almost always multifactorial, which means the most effective approach addresses several things at once. Start by ruling out the most impactful causes: medication side effects, hormonal changes, and relationship issues. Then layer in the lifestyle factors that build desire over time. A realistic starting point might look like adding three 30-minute sessions of mixed cardio and strength training per week, improving sleep consistency, and having an honest conversation with your partner about what you both need.
Give changes at least 8 to 12 weeks before evaluating whether they’re working. Hormonal shifts from exercise take about 16 weeks to fully develop, and behavioral approaches like sensate focus require time and repetition. Libido rarely returns overnight, but with the right adjustments, it does return.
