Ejaculation occurs when a man reaches sexual climax and semen is ejected from his penis. Premature ejaculation is when:

  • Ejaculation occurs before the man wishes it to occur.
  • Ejaculation occurs too quickly to sexually satisfy his partner.

Many men experience premature ejaculation at one time or another. For example, some men experience it after not having had sex for a long period of time. Premature ejaculation is only a problem when it becomes a persistent condition.

Ejaculation occurs automatically after a certain degree of sexual stimulation. Persistent premature ejaculation usually results from a man's inability to recognize that he is about to ejaculate. This inability prevents him from taking steps to delay the process.

Psychological factors may contribute to premature ejaculation. This may include difficulty in the relationship with a partner, guilt about sex, or fears related to sex.

In rare cases, premature ejaculation can be caused by:

  • Prostate problems, such as prostatitis
  • A problem with the nerves
  • Medications that increase sexual stimulation
  • Certain medical conditions (such as thyroid problems)
