Difficulty reaching climax during sex is more common than most men realize. Roughly 3% of sexually active men experience it consistently, and in surveys of men over 57, as many as 20% report trouble reaching orgasm. The causes range from medications and habits to nerve signals and psychological factors, and most are treatable once identified.
Clinically, this is called delayed ejaculation or male anorgasmia. It’s considered a persistent issue when it happens during 75% or more of sexual encounters over at least six months. Some men have dealt with it their entire lives, while others develop it after years of normal function. Both forms have different likely causes and different paths to improvement.
Medications Are the Most Common Culprit
Antidepressants, particularly SSRIs, are the single most frequent cause of difficulty reaching climax. In one study, 73% of men on SSRIs reported sexual side effects, and orgasmic dysfunction specifically affected 61% of men taking sertraline over a 16-week trial. The rates are high across the entire drug class: paroxetine causes sexual side effects in about 71% of users, citalopram in 73%, and fluoxetine in 58%. These drugs work by increasing serotonin levels in the brain, which helps with depression but also raises the threshold for orgasm significantly.
Bupropion, a different type of antidepressant, carries a much lower risk. Only about 10% of men in one comparison study reported orgasmic problems with bupropion versus 61% on sertraline. If you suspect your antidepressant is the issue, your prescriber may be able to switch medications or lower the dose, since this side effect is often dose-dependent. Reducing to the minimum effective dose sometimes resolves the problem without losing the antidepressant benefit.
Other medications that can delay or prevent climax include blood pressure drugs, antipsychotics, and anti-seizure medications. These work through different pathways: some raise prolactin levels, which suppresses orgasm signaling, while others reduce the amount of free testosterone available in the body.
Masturbation Style and Frequency
This is one of the most under-discussed causes. Many men who can climax easily on their own but struggle with a partner have developed what sex therapists call an “idiosyncratic masturbatory style,” meaning a technique that can’t be replicated by a partner’s hand, mouth, or body. This involves some combination of unusual speed, intense pressure, a specific body position, or stimulation focused on one particular spot. Over time, the nervous system adapts to these very specific conditions, and partnered sex doesn’t provide enough of the right kind of stimulation to cross the threshold.
Three masturbation-related factors are most strongly linked to the problem: frequency greater than three times per week, an idiosyncratic technique, and a gap between the fantasies used during masturbation and what actually happens during sex with a partner. The solution involves gradually retraining your body’s response by changing technique, reducing frequency, and approximating the kind of stimulation you’d experience with a partner. Switching your dominant hand is one commonly recommended starting point.
Alcohol and Substance Use
Alcohol directly interferes with the brain’s ability to send and receive the signals needed for orgasm. It slows central nervous system activity, disrupts neurotransmitter function, and alters hormone levels, raising prolactin and cortisol while lowering testosterone. Even a single episode of heavy drinking can make climax difficult or impossible. Chronic heavy use compounds the problem by fundamentally changing how your brain’s chemical messaging systems operate.
The effect isn’t limited to being drunk in the moment. Long-term alcohol use can create lasting changes in neurotransmitter balance that persist even when you’re sober. During withdrawal, the brain overcompensates with heightened nervous system activity that further impairs sexual function.
Nerve and Vascular Damage
Orgasm depends on a chain of nerve signals traveling between the genitals, spinal cord, and brain. Anything that disrupts that chain can prevent climax. Diabetes is one of the most common causes because it gradually damages small nerve fibers throughout the body, including the ones responsible for genital sensation. The longer blood sugar has been poorly controlled, the greater the risk.
Multiple sclerosis damages the protective coating around nerve fibers in the brain and spinal cord, which can slow or block the signals involved in orgasm. Spinal cord injuries, depending on their location and severity, may partially or completely interrupt the pathway. Pelvic surgery, particularly prostate surgery, can damage the nerves running alongside the prostate that play a direct role in ejaculation. Radiation therapy to the pelvic area carries similar risks.
Hormonal Imbalances
Testosterone plays a facilitating role in the ejaculatory reflex. Low levels can reduce sexual desire and make climax harder to reach, though the relationship isn’t as straightforward as many men assume. Studies have not found a strong direct correlation between testosterone levels and ejaculation time, suggesting testosterone is one piece of a larger picture rather than the sole driver.
Elevated prolactin, a hormone normally involved in milk production, suppresses orgasm signaling. Prolactin levels can be raised by certain medications (SSRIs, antipsychotics, and some blood pressure drugs), by chronic alcohol use, or by a benign pituitary growth. Thyroid disorders, both overactive and underactive, have also been linked to ejaculatory difficulty, and these are easily screened with a blood test.
Psychological and Relationship Factors
The brain is the primary organ involved in orgasm, so psychological factors carry real physiological weight. Performance anxiety creates a feedback loop: worrying about whether you’ll be able to climax activates the sympathetic nervous system (the fight-or-flight response), which directly opposes the relaxation state needed for orgasm. The more you focus on monitoring your own arousal, a pattern therapists call “spectatoring,” the harder it becomes to stay in the moment.
Depression and chronic stress independently dampen sexual response through changes in brain chemistry, particularly serotonin and dopamine levels. Relationship tension, trust issues, and difficulty communicating about sex all add layers of inhibition. A history of sexual trauma or deeply held guilt around sex, whether from religious upbringing or cultural messages, can create powerful unconscious barriers to letting go during sex.
For many men, the cause is a combination of physical and psychological factors reinforcing each other. A medication side effect creates one or two frustrating experiences, which then triggers performance anxiety, which makes the problem worse even on nights the medication effect would have been minimal.
How the Problem Is Treated
Treatment depends entirely on the cause, which is why a thorough evaluation matters. A healthcare provider will typically ask detailed questions about your sexual history, including how you masturbate, what medications you take, how much you drink, and whether the problem is new or lifelong. Blood work to check hormone levels and blood sugar is standard.
If a medication is responsible, switching to an alternative or adjusting the dose is often the first step and frequently the most effective one. For men whose masturbation habits are the primary factor, a structured behavioral approach, gradually retraining the body’s arousal response through changes in technique and fantasy, has strong clinical support. This is sometimes done with guidance from a sex therapist using a model called the Sexual Tipping Point, which maps out the combination of physical stimulation and mental arousal needed to reach orgasm and then systematically adjusts both.
For psychological causes, therapy focused specifically on sexual function tends to work better than general talk therapy. Cognitive behavioral approaches help break the spectatoring and anxiety cycle. Couples therapy can address the relationship dynamics that often develop around the issue, since partners frequently internalize the problem as a reflection of their own attractiveness or desirability.
When nerve damage or a medical condition is involved, treatment focuses on managing the underlying disease, optimizing whatever nerve function remains, and often incorporating vibrating stimulation devices that provide more intense input than manual stimulation alone. For hormonal causes, correcting the imbalance through appropriate treatment typically restores function over a period of weeks to months.
