What are the causes of premature ejaculation?

By Dr. Praveen Tripathi - January 20, 2019

Premature ejaculation is caused primarily by two factors:

1. Penile hypersensitivity, which refers to an oversensitive penis which gets excited to climax with minimal stimulation
2. Excessive arousal during sexual interactions.

The factors that contribute to the development of penile hypersensitivity and excessive arousal are the following,

1. Low serotonin levels in the brain: Serotonin, which is a neurotransmitter (a chemical in the brain) controls various aspects of sexual functioning. Low serotonin levels have been linked to premature ejaculation, and hence drugs that can increase serotonin levels often are used in the treatment of PME
2. Anxiety: Persons who have had ejaculation in the past, get under a lot of stress and anxiety when they indulge in sex, as they desperately try to ‘perform better’. But unfortunately, the stress of performance further decreases the duration of sex.

3. New partner: Often, when sex is initiated with a new partner, there is extra arousal which contributes to premature ejaculation.

4. Low frequency of sex: If sex is infrequent, it may lead to excessive excitement during the sex, and hence the premature ejaculation

5. Use of alcohol, tobacco and drugs

6. Presence of erectile dysfunction: Many times, patients with erection problems develop premature ejaculation as they rush through the sexual intercourse, for the fear of losing the erection

Whatever may be the initial cause, once a cycle of premature ejaculation starts, it may continue as the body gets trained for rapid excitement and ejaculation. Hence, medical treatment is required to break this cycle and re-establish a normal sexual rhythm.
