What causes premature ejaculation?
Most cases of premature ejaculation do not have a clear cause. With sexual experience and age, men often learn to delay orgasm. Premature ejaculation may occur with a new partner. It may happen only in certain sexual situations or if it has been a long time since the last ejaculation. Psychological factors such as anxiety, guilt, or depression can also cause it. In some cases, it may be related to a medical cause such as hormonal problems, injury, or a side effect of certain medicines.
