Low Sex Drive? Causes, Treatments & Medications That Actually Work

You used to want it. Now you don't — or at least, not nearly as much. And you are not sure when things changed.

If that sounds familiar, you are far from alone. According to a 2020 study published in JAMA Internal Medicine, roughly 1 in 3 adult women and 1 in 6 adult men in the United States report persistently low sexual desire. That is tens of millions of people — most of whom never bring it up with a doctor.

The frustrating part? Low sex drive is one of the most treatable issues in sexual health. But you have to understand what is actually causing it before you can fix it.

This guide breaks down the real reasons your libido might be low, what treatments have solid evidence behind them, and which medications doctors actually prescribe — for both men and women.

What Counts as a "Low" Sex Drive?

First, let's get something straight: there is no magic number for how often you should want sex. Desire is personal. It varies by age, life stage, stress level, relationship dynamics, and a hundred other factors.

A low sex drive becomes a medical concern when:

• Your desire has noticeably dropped compared to your own baseline
• The change is causing you distress or straining your relationship
• It has lasted for several weeks or months, not just a bad week

If you are content with your current level of desire and it is not causing problems, there is nothing to "fix." But if the change is bothering you — keep reading.

Common Causes of Low Sex Drive in Men

Men often assume low desire is just an age thing. It usually is not. Here are the most common culprits:

Low Testosterone

Testosterone is the primary driver of male sexual desire. Levels naturally decline about 1% per year after age 30, but some men experience more significant drops. The American Urological Association defines low testosterone as below 300 ng/dL. Symptoms include reduced libido, fatigue, mood changes, and difficulty maintaining muscle mass.

Stress and Mental Health

Chronic stress floods your body with cortisol, which directly suppresses testosterone production. Depression and anxiety are equally damaging — and many antidepressants (especially SSRIs) list decreased libido as a side effect. It becomes a frustrating loop: the condition lowers your drive, and the medication to treat it lowers it further.

Poor Sleep

A University of Chicago study found that men who slept five hours a night for one week had testosterone levels comparable to someone 10 to 15 years older. Sleep is not optional for sexual health.

Medications

Blood pressure medications (especially beta-blockers), antidepressants, opioids, and even some hair loss treatments can significantly reduce libido. If your desire dropped after starting a new medication, that is probably not a coincidence.

Relationship Issues

Unresolved conflict, lack of emotional connection, or simple routine can quietly erode desire over time. This is more common than most men want to admit.

Common Causes of Low Sex Drive in Women

Female sexual desire is complex — influenced by hormones, psychology, relationship quality, and physical health simultaneously. The most common causes include:

Hormonal Changes

Menopause is the most well-known trigger, but hormonal shifts during pregnancy, postpartum, breastfeeding, and even from oral contraceptives can significantly reduce desire. Estrogen and testosterone both play roles in female libido — yes, women need testosterone too, just in smaller amounts.

Pain During Sex

If sex hurts, your brain learns to avoid it. Conditions like vaginal dryness, endometriosis, or vulvodynia make intercourse uncomfortable or painful. According to the American College of Obstetricians and Gynecologists, nearly 75% of women experience painful sex at some point — and for many, it becomes chronic.

Body Image and Self-Esteem

Research from the Journal of Sex Research consistently shows that body image is one of the strongest predictors of sexual desire in women. Feeling disconnected from or unhappy with your body makes it hard to feel present and desiring during intimacy.

Mental Load and Fatigue

The invisible labor of managing a household, career, and family leaves many women physically and mentally drained. Desire requires mental space — and when that space is occupied by grocery lists and work deadlines, libido takes a back seat.

Medications

SSRIs, hormonal birth control, antihistamines, and blood pressure medications can all dampen desire. If the timing lines up with a new prescription, talk to your doctor about alternatives.

When to See a Doctor

A lot of people try to fix low libido on their own — supplements, lifestyle hacks, hoping it will pass. Sometimes that works. But you should see a healthcare provider if:

• Your low desire has lasted more than two to three months
• It came on suddenly without an obvious cause
• You are also experiencing fatigue, mood changes, or weight gain (possible hormonal issue)
• It is affecting your relationship or mental health
• You suspect a medication is the cause

Your doctor will likely run blood work (testosterone, thyroid, prolactin levels) and ask about your mental health, relationship, and medication history. It is a straightforward conversation — and one that millions of Americans have every year.

Treatments That Actually Work

For Men

For men whose low libido is connected to erectile difficulties, PDE5 inhibitors are often the first step. These medications do not directly increase desire, but by restoring reliable function, they remove the anxiety and avoidance that killed the drive in the first place.

Commonly prescribed options include:

• Sildenafil (Viagra) — works within 30 to 60 minutes, lasts 4 to 6 hours. Available as generic Sildenafil tablets at a fraction of the brand-name cost.
• Tadalafil (Cialis) — lasts up to 36 hours, often preferred for its flexibility. Available as Tadalafil 10 mg and Tadalafil 20 mg.
• Vardenafil (Levitra) — similar to sildenafil with slightly fewer visual side effects. Available as generic Vardenafil tablets.

All three require a prescription and should be used under medical supervision.

For Women

Flibanserin was the first FDA-approved medication specifically for low sexual desire in women. It is not a "female Viagra" — it works on brain chemistry, not blood flow. Results take several weeks, and it requires daily use. It is available as Lovegra tablets.

For postmenopausal women, vaginal estrogen creams or rings can address dryness and discomfort, which often restores desire once sex stops being painful. Options include Estrogen cream and Vaginal moisturizers.

Lifestyle Changes That Make a Real Difference

Medication is not always necessary. For many people, these changes alone can bring desire back:

• Exercise regularly. A 2018 meta-analysis in the British Journal of Sports Medicine found that consistent aerobic exercise improved sexual function scores by 25% on average — in both men and women.
• Prioritize sleep. Seven to nine hours consistently. Non-negotiable for hormonal health.
• Manage stress actively. Meditation, therapy, exercise — pick what works for you and stick with it.
• Limit alcohol. A drink or two might lower inhibitions, but regular heavy drinking suppresses testosterone and dampens arousal in both sexes.
• Talk to your partner. Research from the Kinsey Institute shows that couples who communicate openly about desire have significantly higher sexual satisfaction — even when one partner has low libido.

Supplements: What the Evidence Says

The supplement market for libido is enormous — and mostly unregulated. Here is what actually has some scientific backing:

• DHEA — may help women with adrenal insufficiency-related low desire. Mixed evidence for men.
• Ashwagandha — a small 2015 study in BioMed Research International showed improved arousal and sexual satisfaction in women. Moderate evidence for reducing stress-related libido issues in men.
• Maca root — some evidence for improved desire in both sexes, though study quality is limited.
• Fenugreek — may support testosterone levels in men. A 2020 study in Phytotherapy Research showed modest improvements.

Be cautious with anything making dramatic claims. If a supplement promises to "10x your sex drive overnight," it is marketing, not medicine.

The Bottom Line

Low sex drive is common, it is not your fault, and it does not have to be permanent.

Whether the cause is hormonal, psychological, medication-related, or a mix of everything — there are real, evidence-based solutions available. The first step is understanding what is behind your specific situation. The second step is having an honest conversation with a healthcare provider.

You deserve a sex life that works for you. That is not a luxury — it is part of your overall health and well-being.
