Premature ejaculation has various timing definitions ranging from ejaculating within one minute of penetration to ejaculating prior to a man's partner achieving orgasm. Essentially, a man or a couple can suffer from rapid ejaculation if one or both is unhappy with how rapidly the man ejaculates. For some couples, RE can occur 30 seconds into vaginal penetration.

As long as one of the partners is dissatisfied, RE is a problem. A man doesn’t have much control over how quickly he ejaculates. Ejaculation is mostly an event of the autonomic nervous system, the part of our nervous system we can’t fully control. Heartbeat, digestion, sweating are all examples of neurologic processes our autonomic nervous system controls. Therefore, when a man gets a signal to ejaculate, the point of no return, he’s going to go. The most sensitive part of the penis is the area around the frenulum, the skin flap on the underside of the penis just below the urethral meatus (where he urinates). There is a spinal cord pathway that connects there and rapidly sends signals to the ejaculation center of the spinal cord.

• Dapoxetine is contraindicated with certain medications and health conditions.
• Topical creams should be used sparingly to prevent partner numbness.
• SSRI treatment may cause emotional blunting or decreased libido.
• Tramadol's risk of dependency requires careful medical supervision.
• Mechanical devices can provide temporary ejaculation delay.
• Behavioral training involves specific sex exercises for control.
• Mindfulness and relaxation techniques benefit PE management.
• Proper diagnosis is essential to rule out underlying disorders.
• Incorporate partner feedback to improve treatment results.
• Avoid abrupt discontinuation of prescribed medication.
• Lifestyle modifications can include weight management.
• Ongoing research aims to develop more effective PE treatments.

Serotonin, dopamine, prolactin, testosterone and oxytocin are all hormones that play a role in ejaculation. This is a very troubling condition for men as it compromises their sexual satisfaction and inhibits them in relationships. Some recent studies shed light on PE and RE but the exact causes are still not known. Psychological: Classic literature on RE suggests it is a trained sexual response fostered by men secretively masturbating as adolescents and trained to finish quickly. This behavior was then reinforced with early partner encounters where young couples engage in clandestine sexual activity in parents’ basements or car back seats. There is no proof that this is a real thing, however, and physicians suggesting this as a cause of RE reinforces guilt associations with sexuality. Neurobiological: The neurotransmitter serotonin (5HT) plays a central role in the ejaculatory response. Low levels of serotonin in specific areas of the brain may lead premature ejaculation.

• Dapoxetine's side effects can include nausea, headache, and dizziness.
• Topical anesthetics include lidocaine and prilocaine-based creams or sprays.
• SSRIs like fluoxetine, sertraline, may also be used off-label for PE.
• Opioid medications require careful medical oversight due to dependency potential.
• Behavioral approaches are first-line treatment for many men with PE.
• Regular exercise can improve overall sexual function and control.
• Some innovations include vibration devices to delay ejaculation temporarily.
• Medical tests may be recommended to exclude underlying causes.
• Education about sexual response stages can improve control strategies.
• Sex therapy often involves both partners to address relational issues.
• Medications may take several weeks to show maximum benefit.
• Lifestyle modifications, like reducing alcohol, can also help manage PE.

Studies have shown that increases in serotonin levels can help delay ejaculation in some men.

What Are the Signs and Symptoms of Premature Ejaculation?

There was no effect of food on elimination of this agent, with < 5% of peak plasma concentration being present 24 hours after oral administration. Interestingly, the most frequent AE with dapoxetine is nausea, which was decreased after a high-fat meal (24% of fasted and 14% of fed subjects). Perhaps a complete steak dinner will be required with this medication for the patients who complain of nausea. The question of daily dosing and accumulation was reported in a study of 42 healthy males. [14] Dapoxetine was rapidly absorbed with mean maximal plasma concentrations achieved at 1.01 and 1.27 hours after single doses of dapoxetine 30 and 60 mg.

On this page:

With repeated daily dosing, steady-state plasma concentrations were reached within 4 days, with modest accumulation (1.5-fold). Elimination of dapoxetine was rapid and biphasic, with initial and terminal half-lives of 1.4 and 20 hours. The authors concluded that the pharmacokinetic profile of dapoxetine is ideally suited to an on-demand oral therapy for PE. Even though PE is the most common male sexual dysfunction, it seems to be under-reported by patients and underestimated by physicians. There have been 2 large surveys conducted -- buy cenforce pills one that looked at the prevalence and attitudes regarding PE among 11,543 men from the United States, Germany, and Italy, and another querying 271 physicians (primary care physicians, urologists, and psychiatrists) from the United States, Germany, Italy, and Mexico..[15] Seventy-two percent of men with self-reported PE claimed significant worry about their ability to last during intercourse, with 59% reporting frustration at climaxing too soon.

When should I see a doctor about my premature ejaculation symptoms?

In contrast, > 90% of physicians thought that PE caused only minor or no distress to their patients. Approximately 12% of men stated that they had consulted a physician for this condition, with 80% claiming to have initiated the conversation and 85% reporting little or no improvement from this medical interaction. Clearly, PE is a common and distressing condition for a sizeable segment of the male population. Patients and couples often seek expensive and ineffective off-label therapies. Education about PE, its prevalence, and beneficial therapies for both consumers and physicians is urgently needed. This provides the rationale for treating RE with anti-depressants in the selective serotonin reuptake inhibitor (SSRI) class.

Treatment Options for Premature or Rapid Ejaculation at UCLA

In preclinical studies, dapoxetine was found to be a potent inhibitor of serotonin reuptake and is considered by authorities in the field to be a serotonin transporter inhibitor. In experimental animal studies, researchers from Paris, France, evaluated the emission and expulsion phases of ejaculation using p-chloroamphetamine-induced ejaculation in anesthetized rats. [7] Different doses of intravenous dapoxetine reduced both the emission and expulsion phases in a dose-dependent manner. Similar experiments in the same anesthetized-rat model were conducted to elucidate the drug's mechanism of action. These studies revealed that dapoxetine worked by increasing the pudendal motor neuron reflex latency period.

American Urological Association and Sexual Medicine Society of North America

Dapoxetine has previously demonstrated its efficacy in the treatment of PE in 2 identically designed, double-blind, randomized, placebo-controlled, 12-week phase III trials. [9] An open-label, long-term (1 year) on-demand study of dapoxetine efficacy was presented. [10] Of the 1774 men enrolled in the 3-month studies (placebo, dapoxetine 30 mg and 60 mg) all were provided with dapoxetine 60 mg to be taken as needed 1 to 3 hours before sexual intercourse. Patients were evaluated at 1, 2, 3, 6, and 9 months in this extension study. The final results showed that the improvements in satisfaction with sexual intercourse, control of ejaculation, symptom severity, and benefit from the medication were maintained through the duration of the study.

Early Climaxing Before or Shortly after Penetration

Further analysis of the data sets from different groups of researchers revealed that dapoxetine equally improved IELT in men with both acquired and lifelong PE. [11] Additionally, men with PE who had the lowest IELTs appeared to benefit most. Men with a baseline IELT < 30 seconds had a 6.8-fold increase; those with a baseline IELT > 30 seconds and < 1 minute had a 4.4-fold increase; and those with baseline IELT > 1 minute and ≤ 2 minutes had a 3.2-fold increase. Additional studies involving dapoxetine showed minimal food effects. [13] Mean maximal plasma concentrations of dapoxetine decreased slightly after a high-fat meal, from 443 ng/mL (fasted) to 398 ng/mL (fed), and were delayed by approximately 0.5 hours following a high-fat meal (1.3 hours fasted, 1.63 hours fed). Penile Sensitivity: The ejaculatory spinal cord pathway is located at the ventral tip of the corona (if you’re standing up and looking down at your penis, the ventral side is on the bottom. The corona is the mushroom head of your penis.) If a man has increased sensitivity at that point, he will likely ejaculate too fast. Applying topical numbing agents, usually containing lidocaine, is an effective way to reduce penile sensitivity and prolong ejaculation.
