Libido can be lowered through several well-documented routes, ranging from prescription medications that alter hormone levels or brain chemistry to lifestyle changes like heavy endurance exercise or sustained caloric restriction. The approach that makes sense depends entirely on why you want your sex drive to decrease, and the tradeoffs vary dramatically. Some pharmaceutical options are powerful but carry lasting side effects, while natural strategies tend to produce subtler shifts that are harder to control precisely.
Why Someone Might Want to Lower Their Sex Drive
Before getting into specifics, it helps to understand that the reasons behind this search matter for choosing the right approach. Some people experience compulsive sexual behavior that disrupts their daily life and relationships. Others have a mismatched libido with a partner and are looking for ways to close the gap. Some are on medications that have pushed their sex drive uncomfortably high, particularly certain drugs used in Parkinson’s disease. And some individuals dealing with paraphilic disorders seek medical help to manage urges that could lead to harm. Each of these situations calls for a different strategy, and what works for one can be inappropriate or even dangerous for another.
A conversation with a doctor is the right starting point for anyone considering medication-based approaches. Self-prescribing anti-androgens or repurposing psychiatric drugs to suppress desire introduces serious health risks without proper monitoring. That said, understanding what the options actually are and how they work helps you have a more productive conversation with your provider.
SSRIs and Their Dampening Effect on Desire
Selective serotonin reuptake inhibitors, the class of antidepressants that includes fluoxetine, sertraline, and paroxetine, are among the most commonly prescribed drugs that reduce libido as a side effect. The sexual problems they cause range from decreased desire and reduced excitement to delayed or absent orgasm and erectile difficulties.1PubMed Central. Antidepressant-associated sexual dysfunction: impact, effects, and treatment This is usually considered an unwanted consequence, but in certain clinical settings, particularly for compulsive sexual behavior, therapists and psychiatrists have leveraged this side effect deliberately.
A systematic review of treatments for compulsive sexual behavior found considerable evidence supporting cognitive-behavioral therapy, but also noted something telling about SSRIs: in one study, participants in the placebo control group showed reductions in symptom severity similar to those treated with an SSRI, suggesting the therapeutic relationship and structure of a clinical trial may matter as much as the drug itself.2PubMed Central. Treatments and interventions for compulsive sexual behavior disorder with a focus on problematic pornography use: A preregistered systematic review That does not mean SSRIs have no effect on desire; the sexual side effects are well-established. It means that if your goal is specifically to manage compulsive behavior, an SSRI alone may not be the magic bullet, and behavioral interventions appear to do much of the heavy lifting.
The more concerning issue with SSRIs is what happens after you stop taking them. In most people, sexual function returns to baseline. But in a subset of patients, it does not. This condition, known as post-SSRI sexual dysfunction, is characterized by persistent genital numbness, weakened orgasm, loss of libido, and erectile problems that continue long after the medication has been discontinued.3PubMed Central. Post-SSRI sexual dysfunction: barriers to quantifying incidence and prevalence One study estimated the risk at roughly 1 in 216 patients treated with serotonergic antidepressants.4PubMed Central. Estimating the risk of irreversible post-SSRI sexual dysfunction (PSSD) due to serotonergic antidepressants That is not a huge number, but it is not negligible either, especially if you are taking the drug specifically for its sexual side effects and planning to stop at some point.
Anti-Androgens and Hormone Suppression
Testosterone is the primary hormonal driver of sexual desire in all sexes, though it is far from the only factor. Drugs that block testosterone production or its effects on the body can substantially reduce libido. The most commonly discussed anti-androgens are cyproterone acetate and spironolactone, both of which have been used clinically for decades in various contexts.
Cyproterone acetate directly blocks androgen receptors and suppresses testosterone production. It has been used to treat hypersexuality and paraphilic disorders, as well as androgen-related skin conditions like hirsutism and acne.5Journal of Steroid Biochemistry. Clinical applications of antiandrogens In studies of transgender women receiving estradiol therapy, cyproterone acetate proved significantly more effective than spironolactone at lowering testosterone: one randomized trial found that 90% of the cyproterone group achieved female-range testosterone levels versus only 19% in the spironolactone group.6PubMed. Anti-Androgenic Effects Comparison Between Cyproterone Acetate and Spironolactone in Transgender Women: A Randomized Controlled Trial While those numbers come from a transgender health context where estrogen was also used, they illustrate how much more aggressively cyproterone acetate suppresses testosterone compared to spironolactone.
For people with the most severe or dangerous hypersexual behavior, a more powerful class of drugs exists: GnRH agonists such as leuprolide acetate. These medications suppress testosterone production by overriding the brain’s signaling to the testes, essentially creating a temporary chemical castration. A systematic review found increasing evidence that GnRH agonists are more effective than anti-androgens like cyproterone at reducing paraphilic sexual thoughts and behaviors, though their extensive side effects mean they are typically reserved for the highest-risk patients and combined with psychotherapy.7The Journal of Sexual Medicine. Treatment of Paraphilic Disorders in Sexual Offenders or Men With a Risk of Sexual Offending With Luteinizing Hormone-Releasing Hormone Agonists: An Updated Systematic Review A case series of twelve patients with paraphilic disorders reported that leuprolide acetate significantly suppressed deviant sexual interests and was generally well tolerated.8PubMed. Depot-leuprolide acetate for treatment of paraphilias: a report of twelve cases Another study found significant improvements in symptom severity after twelve months of treatment.9PubMed Central. Therapeutic Effects of Leuprorelin (Leuprolide Acetate) in Sexual Offenders with Paraphilia
The Physical Cost of Androgen Suppression
Any approach that significantly lowers testosterone comes with a broader physiological price. The best-studied data comes from prostate cancer patients on androgen deprivation therapy, which uses some of the same drugs (particularly GnRH agonists) discussed above. After twelve months on this therapy, men experienced roughly a 10% increase in body fat and a 3.5% reduction in lean muscle mass, alongside drops in bone mineral density at nearly every skeletal site measured.10PubMed. Bone loss after initiation of androgen deprivation therapy in patients with prostate cancer The bone loss is clinically significant: androgen deprivation therapy increases fracture risk, and osteoporosis is considered one of its most important complications.11PubMed. Osteoporosis during androgen deprivation therapy for prostate cancer
Beyond bones and body composition, the broader side-effect profile includes hot flashes, breast tissue enlargement, reduced testicle size, anemia, and fatigue.12European Urology. Adverse Effects of Androgen Deprivation Therapy and Strategies to Mitigate Them These effects should give pause to anyone considering testosterone suppression as a casual fix for high libido. The drugs work, but they reshape your metabolism and skeletal health in ways that compound over time. For people with compulsive behavior that poses genuine risk, the trade-off may be warranted. For someone simply looking to match a partner’s lower drive, the risks almost certainly outweigh the benefits.
Other Medications That Reduce Desire
Some antipsychotic medications suppress libido through a different mechanism: by raising prolactin levels. Prolactin-elevating antipsychotics like haloperidol and risperidone block dopamine receptors in a way that causes the pituitary gland to release more prolactin, and elevated prolactin is a well-documented cause of sexual dysfunction in both sexes.13PubMed Central. Antipsychotic-induced sexual dysfunction and its management In women, this can cause loss of libido alongside menstrual disruption; in men, it manifests as impotence and reduced desire.14Schizophrenia Research. Prolactin and antipsychotic medications: mechanism of action These drugs are not prescribed for libido reduction per se, but their effects on desire are worth understanding, particularly if you are already taking one and experiencing changes.
Naltrexone, an opioid receptor blocker typically used for alcohol or opioid addiction, has been explored for compulsive sexual behavior as well. The rationale is that it disrupts the dopamine reward cycle that reinforces compulsive patterns, reducing the salience of the addictive behavior over time.15Mayo Clinic Proceedings. Internet Sex Addiction Treated With Naltrexone The evidence base here is limited mostly to case reports, but it represents a different conceptual approach: rather than suppressing hormones or flooding serotonin, naltrexone targets the reward system that makes compulsive sexual behavior feel irresistible.
Herbal and Dietary Approaches
A few foods and herbs have shown mild anti-androgenic effects in clinical studies, though none approach the potency of pharmaceutical options. Spearmint tea is probably the most cited. A randomized controlled trial in women with polycystic ovarian syndrome found that drinking spearmint tea for 30 days significantly reduced both free and total testosterone levels.16PubMed. Spearmint herbal tea has significant anti-androgen effects in polycystic ovarian syndrome. A randomized controlled trial The researchers confirmed spearmint’s anti-androgen properties, though they noted this hormonal shift did not clearly translate into visible clinical changes in the short timeframe studied. Whether drinking spearmint tea would meaningfully lower libido in someone without PCOS is unknown.
Licorice root, specifically glycyrrhizin-containing licorice (not the anise-flavored candy common in many countries), has also been studied. In a small trial with healthy men, consuming licorice lowered average testosterone by about a quarter after one week of treatment.17PubMed. Licorice consumption and serum testosterone in healthy man That is a notable drop, but this was a very small study, and licorice carries its own risks at high doses: it can raise blood pressure, lower potassium, and cause fluid retention. Treating it as a safe, casual way to lower testosterone would be a mistake.
In general, herbal and dietary approaches to libido reduction are too inconsistent and too weakly studied to be relied on as a primary strategy. They might produce subtle hormonal shifts, but if your libido is genuinely problematic, subtle shifts probably are not enough.
Exercise, Caloric Restriction, and Chronic Stress
Three lifestyle factors can suppress testosterone and reduce desire, though none of them should be adopted for that purpose alone because each carries serious health consequences when taken too far.
Chronic endurance exercise, the kind practiced by committed long-distance runners, cyclists, and triathletes over years, can produce a condition where resting testosterone levels are significantly and persistently reduced. This so-called exercise-hypogonadal male condition does not appear to be common and seems limited to men who have trained heavily for extended periods.18PubMed Central. The exercise-hypogonadal male condition and endurance exercise training Moderate exercise, on the other hand, tends to support healthy testosterone levels rather than suppress them. So if you are hoping a few extra jogs per week will dial down your sex drive, that is unlikely. The testosterone-suppressing effect requires a degree of training that most people neither want nor can sustain.
Sustained caloric restriction, particularly when severe enough to push body mass index below about 20, can suppress the hormonal axis that drives testosterone production. Clinical features in men with energy-deficit-driven hormone suppression include low libido, fatigue, and reduced motivation, though the decrease in sexual desire may not always be the most noticeable symptom among the general malaise.19The Journal of Clinical Endocrinology & Metabolism. Dysregulation of the Hypothalamic–Pituitary–Testicular Axis due to Energy Deficit The severity of the hormonal suppression correlates with the severity of the caloric shortfall. Undereating as a strategy to reduce libido would be self-destructive; but it is worth knowing that if you are already in a caloric deficit for other reasons and noticing a drop in desire, the connection is well established.
Chronic psychological stress works through a similar hormonal pathway. When your body stays in a prolonged stress state, cortisol release suppresses the signals that stimulate testosterone production.20International Journal of Impotence Research. The effect of stress on testosterone and sexual function This inhibition occurs at multiple levels, ultimately reducing stimulation of the cells in the testes that produce testosterone.21Nature Reviews Urology. Effects of psychological stress on male fertility Again, this is not a recommendation to become more stressed. But the mechanism helps explain why people under sustained psychological pressure often experience diminished desire without any other clear cause.
Cognitive-Behavioral and Acceptance-Based Therapy
For people whose distress is less about the raw level of desire and more about compulsive behavior, psychological approaches have the strongest evidence relative to their risk profile. Cognitive-behavioral therapy is the preferred treatment method for compulsive sexual behavior, with common components including awareness of triggering thoughts and emotions, impulse management training, problem-solving skills, mindfulness practices, and relapse prevention planning.22Frontiers in Psychiatry. Evaluation and treatment of compulsive sexual behavior: current limitations and potential strategies The goal is not necessarily to lower desire itself but to change your relationship to it, so that urges no longer dictate behavior.
Acceptance-based approaches, which draw on acceptance and commitment therapy, have shown particularly promising durability. One study following participants for a year after treatment found that reductions in hypersexual behavior and craving interference were maintained at the twelve-month mark. Nine out of ten participants showed clinically meaningful reductions in hypersexuality, and gains in perceived control over cravings held steady.23Frontiers in Psychology. One-year follow-up effects of an acceptance-based treatment for hypersexuality Initial randomized controlled trials have also begun to support the effectiveness of integrated therapeutic models for compulsive sexual behavior.24Nature Reviews Urology. An integrated model to assess and treat compulsive sexual behaviour disorder
These findings suggest that if compulsive behavior is the problem, therapy is a reasonable first-line approach, ideally before layering on medications with significant side-effect profiles. The evidence is not yet as robust as for, say, CBT for depression, but it is building in a consistent direction.
When Medication Causes Unwanted Hypersexuality
Sometimes the question of how to decrease libido arises not because desire has always been high, but because a medication has pushed it into uncomfortable or dangerous territory. This is a recognized problem with dopamine agonists used to treat Parkinson’s disease. Hypersexuality was one of the earliest impulse control disorders linked to Parkinson’s treatment, with an estimated prevalence of about 3.5% among patients on these drugs.25PubMed Central. Hypersexuality in Parkinson’s Disease: Systematic Review and Report of 7 New Cases Dopamine agonist therapy has been linked to hypersexuality alongside other impulsive behaviors like compulsive gambling and shopping.26Behavioural Pharmacology. Impulse control disorders and dopamine dysregulation syndrome associated with dopamine agonist therapy in Parkinson’s disease
If you or someone you know has developed sudden hypersexual behavior after starting a Parkinson’s medication or another dopamine-related drug, the most important step is reporting it to the prescribing physician. Dose adjustment or switching to a different medication often resolves the problem without needing to add a second drug to counteract the first. The broader point is that a sudden change in sexual desire always warrants a medication review, because iatrogenic causes are more common than most people realize.
Matching the Approach to the Problem
The range of options for decreasing libido spans a wide spectrum of intensity and risk. At the gentler end, behavioral and psychological approaches can help you manage compulsive patterns without altering your hormones. In the middle, SSRIs reduce desire as a side effect, but the risk of persistent sexual dysfunction after stopping the medication is real and underappreciated. At the more aggressive end, anti-androgens and GnRH agonists can dramatically lower testosterone, but they bring bone loss, metabolic changes, and a cascade of effects on your body that extend far beyond sexual desire.
Natural approaches like heavy endurance training, caloric restriction, or consuming spearmint tea or licorice may produce some hormonal shifts, but they are neither reliable enough nor powerful enough to treat clinically significant problems. They belong in the category of “things that can happen to your sex drive as a consequence of lifestyle choices,” not “therapies you should pursue to fix a libido problem.”
The framing matters. If you are dealing with distressing sexual urges that feel out of control, the evidence points toward therapy first and medication as an adjunct. If you are dealing with medication-induced hypersexuality, the fix is adjusting the medication causing it. And if you are simply someone who wishes their drive were a bit lower, the honest answer is that no intervention comes without trade-offs, and many of the pharmaceutical options are far more consequential than they appear at first glance.
