Premature ejaculation (PE) is a common sexual dysfunction characterized by the inability to delay ejaculation during sexual activity, leading to distress or dissatisfaction for both the individual and their partner. The exact cause of PE is not always clear, but it often involves a combination of physical, psychological, and emotional factors. In some cases, it may be related to an overactive ejaculatory reflex, which can result from hypersensitivity of the nerves controlling ejaculation. Neurological or hormonal imbalances, such as high levels of prolactin or low serotonin, may also play a role in triggering premature ejaculation. Additionally, inflammation or infection in the prostate or urethra can sometimes contribute to the condition.

Psychological factors, including anxiety, stress, depression, and relationship issues, are frequently associated with premature ejaculation. Performance anxiety, especially in new sexual relationships, can lead to rushing through intercourse and difficulty controlling ejaculation. Psychological distress may also exacerbate the condition, creating a cycle where worry about premature ejaculation itself makes it more likely to occur. In some cases, a history of sexual trauma or negative sexual experiences can lead to lasting emotional consequences that contribute to premature ejaculation. Treatment for PE typically involves addressing both the physical and psychological aspects through therapy, behavioral techniques, and sometimes medications or topical treatments.
