Premature ejaculation is a male sexual dysfunction characterized by the inability to control the timing of ejaculation, resulting in ejaculation that occurs with little sexual stimulation and before it is desired. Symptoms may include ejaculating within a minute after penetration or before desired during sexual intercourse.

The causes of premature ejaculation can be both psychological and physical. Psychological causes may include anxiety, stress, relationship issues, or negative past sexual experiences. Physical causes may include health problems, hormonal imbalances, or neurological conditions. Sometimes, it can be a combination of both factors.

The diagnosis of premature ejaculation is generally based on a medical evaluation that includes a review of the patient's medical history, a physical examination, and a discussion about ejaculation patterns and sexual experiences. No specific laboratory tests are required, but an examination may be performed to rule out other medical conditions.

There are several treatment options for premature ejaculation. These may include behavioral modification techniques, such as the "stop-start" technique, topical medications that numb the penis, and oral medications that help delay ejaculation. Psychological therapy, such as cognitive-behavioral therapy, can also be beneficial in addressing emotional or anxiety issues. It is important to discuss all options with a doctor to find the most suitable treatment.
