What tests are required for premature ejaculation?

Generally, premature ejaculation (PE) examination should focus on identifying the underlying causes, mainly including medical history inquiry, physical examination, reproductive system ultrasound, hormone level testing, and nerve sensitivity assessment. A comprehensive evaluation can determine whether PE is related to psychological factors, reproductive system disorders, hormonal imbalances, or heightened nerve sensitivity. The specific analyses are as follows:

1. Medical History Inquiry: The physician will ask detailed questions regarding sexual history, including ejaculation latency, ejaculation control ability, frequency of sexual activity, and relationship with the partner. Additionally, the patient's past health conditions will be reviewed, such as whether there is prostatitis, diabetes, or other underlying diseases, whether any medications have been taken long-term, and whether there are psychological conditions such as anxiety or inferiority. This inquiry helps the physician to preliminarily identify possible causes of PE.

2. Physical Examination: Focuses on the reproductive system, examining the appearance of the penis and glans for any deformities, inflammation, or injuries. The physician will palpate areas such as the prostate and testicles to check for conditions like prostate enlargement or abnormal testicles. Additionally, the genital and perineal nerve reflexes will be assessed to evaluate nerve conduction function preliminarily, helping to rule out organic causes of PE.

3. Reproductive System Ultrasound: Ultrasound imaging of the prostate, seminal vesicles, and testicles is performed to detect conditions such as prostatitis, prostatic hyperplasia, seminal vesicle effusion or inflammation, and abnormal testicular development. These findings can help determine whether structural abnormalities in the reproductive system are affecting ejaculation control and causing PE.

4. Hormone Level Testing: Venous blood is drawn to measure six key sex hormones and thyroid function indicators. Low testosterone levels or abnormal thyroid function may affect reproductive system function and neural regulation, potentially leading to rapid ejaculation. This test helps identify whether hormonal imbalances are contributing to PE.

5. Nerve Sensitivity Testing: Specialized equipment is used to measure the sensory thresholds of the glans and shaft of the penis, assessing the nerves' sensitivity to stimulation. A low sensory threshold in the glans indicates heightened nerve sensitivity, which can lead to PE. This test provides valuable information for guiding targeted treatment.

Following the examinations, a tailored treatment plan should be developed based on the results. If psychological factors are predominant, psychological counseling may be emphasized. If there are organic diseases or hormonal abnormalities, the underlying condition should be treated first. In daily life, maintaining regular sleep patterns and engaging in moderate exercise can help improve overall physical condition, laying a solid foundation for further interventions.
