Premature ejaculation: what it is, what causes it, and how it differs from ED

The short version: premature ejaculation (PE) is a timing and control problem, not an erection problem. It means regularly ejaculating sooner than you want, feeling you have little say in when it happens, and being bothered by it. It is one of the most common sexual concerns men report, it often has no single identifiable cause, and it sometimes travels with erectile dysfunction (ED), which is a different condition. This page covers how experts define PE, what research links to it, how to tell it apart from ED and from delayed ejaculation, and when it is worth raising with a clinician. Treatment options have their own page: premature ejaculation treatment.

What is premature ejaculation?

Premature ejaculation is ejaculation that happens sooner than a man or his partner wishes, over and over, with a poor sense of control and real distress about it. The NHS puts it simply: it is when a man ejaculates “sooner than he or his partner wishes,” and occasional episodes are common and not a cause for concern (NHS, Ejaculation problems). What turns it into a diagnosis is the pattern plus the bother, not one rushed night.

The International Society for Sexual Medicine (ISSM) published what it calls the first evidence-based definition of PE. It has three parts: short timing, an inability to delay ejaculation nearly every time, and negative personal consequences such as distress, frustration or avoiding intimacy (Serefoglu et al., ISSM definition, 2014). All three have to be there. A short time on its own, without the loss of control and the distress, does not meet the definition.

Lifelong vs acquired PE: what is the difference?

Lifelong PE has been present since a man first became sexually active, while acquired PE starts later, after a period of normal timing. The ISSM definition puts lifelong PE at ejaculation that always or nearly always happens within about 1 minute of starting intercourse, and acquired PE at a clinically significant, bothersome drop in timing, often to about 3 minutes or less (ISSM definition). The 2020 American Urological Association and Sexual Medicine Society of North America (AUA/SMSNA) guideline uses a slightly wider window of about 2 minutes for lifelong PE (AUA/SMSNA Disorders of Ejaculation guideline).

The split matters because the two types tend to point in different directions. The AUA/SMSNA guideline says clinicians should not order extra tests for lifelong PE, but may for acquired PE when the history suggests a cause worth looking for (Statements 5 and 6). It also describes two softer patterns that do not meet either definition: occasional short timing that comes and goes, and worry about timing that is actually within the normal range. For both, the guideline favors education and counseling over medicine.

How common is premature ejaculation?

Clinical premature ejaculation is estimated to affect fewer than 5% of men, even though far more say they ejaculate too soon. In surveys, up to about 30% of men say they ejaculate early, yet the AUA/SMSNA guideline estimates that fewer than 5% have bothersome clinical PE (AUA/SMSNA guideline). The ISSM puts lifelong PE, defined by the 1-minute mark, at no more than about 4% of the general population (ISSM guideline update, 2014).

For context, the AUA/SMSNA guideline reports that in stopwatch studies of men in Western countries, the median time to ejaculation was between 5 and 6 minutes, with a very wide range. In an online survey of more than 12,000 men aged 18 to 70 in the United States, Germany and Italy, 22.7% reported low control plus distress, and only 9% of them had ever talked to a doctor about it (Porst et al., PEPA survey, 2007). If this is something you have never mentioned to a doctor, you are in the large majority.

What causes premature ejaculation?

The honest answer is that no one cause has been proven. The ISSM guideline states that the cause of PE is not known and that no biological factor has been shown to cause it in most men (ISSM guideline update). What research has found are factors linked to it, and those links are associations, not proof that one thing causes the other in any given man.

The factors with the most support:

• Serotonin signaling. Serotonin is the brain chemical with the strongest data in the control of ejaculation, and it tends to delay ejaculation. One leading theory is that some men with lifelong PE have differences in serotonin receptors that lower their threshold (ISSM guideline update). The AUA/SMSNA guideline likewise describes serotonin activity as opposing ejaculation, while dopamine and oxytocin promote it.
• Genes. Family and twin studies suggest a moderate genetic influence, which the ISSM reads as a predisposition rather than a direct cause.
• Psychological and relationship factors. The ISSM lists developmental factors (such as sexual abuse or attitudes about sex absorbed in childhood), individual factors (such as depression, performance anxiety and body image) and relationship factors (such as partner conflict or reduced intimacy). It notes the link often runs both ways: anxiety can feed PE, and PE can deepen the anxiety.
• Thyroid problems. An overactive thyroid has been linked to acquired PE. In one study cited by the ISSM, the share of hyperthyroid men with acquired PE fell from 50% to 15% once their thyroid levels were brought back to normal. The same guideline reports no thyroid link in lifelong PE, and notes that the link with acquired PE has been found in very few patients.
• Prostate inflammation. Between 26% and 77% of men with chronic prostatitis or chronic pelvic pain report early ejaculation, though the mechanism is unknown and the ISSM does not recommend routine screening for it in men with PE.
• Erectile dysfunction. ED is linked to acquired PE in particular (more on this below).

The NHS lists a similar mix. Physical causes it names include prostate problems, thyroid problems and recreational drug use; psychological causes include depression, stress, relationship problems and anxiety about sexual performance, particularly early in a new relationship (NHS). For men who have had PE since they became sexually active, the NHS mentions conditioning from rushed early experiences, a past traumatic sexual experience, and a strict upbringing around sex. The ISSM also lists withdrawal from some prescribed medicines among proposed factors, but stresses that none of these proposed causes has been confirmed in large studies.

One thing that is not a cause: circumcision status. The AUA/SMSNA guideline says clinicians should tell men that timing is not affected by whether or not they are circumcised (Statement 7).

How does premature ejaculation differ from erectile dysfunction?

PE is about when ejaculation happens and how much control you have over it. ED is about the erection itself: NIDDK defines it as a condition that prevents you from getting or keeping an erection firm enough for sex (NIDDK, Definition and Facts for ED). A man with PE alone usually has a normal erection; the issue is that climax comes before he wants it to.

The two are easy to mix up, and the ISSM guideline gives two common examples. Some men say they have ED when what they really mean is that they cannot get a second erection quickly after ejaculating. Others with ED say they have PE, because they hurry to finish before they lose the erection, and ejaculate fast as a result (ISSM guideline update). Sorting out which problem came first changes what a clinician looks at, which is a good reason to describe the sequence honestly at an appointment.

Can premature ejaculation and ED happen together?

Yes. In a global survey of 11,205 men in 29 countries cited by the ISSM, men who sometimes or often had erection difficulties were more likely to also report early ejaculation, in every region studied. Not every population study has found this link, though (ISSM guideline update). In a survey of more than 12,000 men, those with PE were more likely to report other sexual problems, including ED and low libido, as well as depression, anxiety and stress (PEPA survey).

The ISSM concludes that ED is unlikely to explain lifelong PE but is associated with acquired PE. In pooled data from two clinical trials of a PE medicine, ED was more common in men with acquired PE than in men with lifelong PE (24% vs 15%). The ISSM suggests two possible reasons: performance anxiety, or deliberately speeding up to finish before the erection fades. Men who have both may have more severe symptoms of each and lower satisfaction. That is why the AUA/SMSNA guideline tells clinicians to treat ED in men who have both according to the AUA’s ED guideline (Statement 12), and why the ISSM recommends that men with ED be screened for PE. If you think anxiety is part of the picture, see ED vs performance anxiety.

How does premature ejaculation differ from delayed ejaculation?

They are opposite problems with the same moving part. Delayed ejaculation means a consistent, bothersome difficulty reaching ejaculation, or not reaching it at all, despite enough stimulation and wanting to (AUA/SMSNA guideline, Statements 16 and 17). The NHS says you may have it if you are unable to ejaculate more than half the times you have sex (NHS).

The causes overlap on the psychological side, with stress, depression and relationship problems named for both. The physical picture differs. The NHS links delayed ejaculation to diabetes, spinal cord injury, multiple sclerosis, bladder or prostate surgery and increasing age, and to medicines including antidepressants (especially SSRIs), some blood pressure medicines such as beta-blockers, and antipsychotics. The AUA/SMSNA guideline notes that in older men delayed ejaculation often occurs alongside low desire or ED, and that some men first notice it after their ED is successfully treated. If a medicine may be involved, do not stop it on your own; the guideline’s approach is for the prescriber to consider replacing, adjusting or tapering it (Statement 22). For the wider list of drugs that can affect sexual function, see medications that affect erections.

Is any medicine FDA-approved for premature ejaculation?

No. The AUA/SMSNA guideline states that none of the medicines used for PE has been approved by the US Food and Drug Administration, so their use for PE is off-label (AUA/SMSNA guideline). The guideline still recommends several options, alongside counseling and behavioral approaches, and notes that combining the two may work better than either alone (Statement 13). Dapoxetine, a medicine designed for PE, is licensed in the UK (NHS) and, as of 2014, had been approved in more than 50 countries (ISSM guideline update), but like every PE medicine it is not FDA-approved in the US. The guideline also says there is not enough evidence to support alternative therapies, and that surgery or bulking injections for PE should be treated as experimental (Statements 14 and 15). What each option involves is covered on the premature ejaculation treatment page; which, if any, fits you is a decision to make with a clinician.

When to talk to a clinician

The NHS advice is to see a GP if you have a persistent problem with ejaculation (NHS). Raise it sooner if:

• the change is new, after years of timing you were happy with, since acquired PE is the type for which the AUA/SMSNA guideline allows extra testing;
• you are also having trouble getting or keeping an erection;
• you have other new symptoms, such as pelvic pain or a known or suspected thyroid problem;
• it began after starting or stopping a medicine;
• it is causing real distress, avoidance or strain in a relationship.

What to expect: the AUA/SMSNA guideline says the evaluation should include your medical, relationship and sexual history and a focused physical exam (Statement 3), and that a referral to a mental health professional with expertise in sexual health is worth considering (Statement 8). It is a routine conversation for a urologist or primary care clinician. Our guides on talking to a doctor about ED and when to see a doctor about ED cover how to start it, and our overview of erectile dysfunction explains the erection side of the picture.
