Premature ejaculation means the man ejaculates too quickly. Some times it occurs because the man has not learnt to control the ‘point of inevitability’ – the sign that tells you that you are about to orgasm. As a result ejaculation may occur before penetration, or soon afterwards, which may leave you and your partner frustrated.
Delayed ejaculation is a medical condition in which a male cannot ejaculate, either during intercourse or by manual stimulation with a partner. Most men ejaculate within a few minutes of starting to thrust during intercourse. Men with delayed ejaculation may be unable to ejaculate (for example, during intercourse), or may only be able to ejaculate with great effort after having intercourse for a long time (for example, 30 to 45 minutes).
Delayed ejaculation can have psychological, or physical causes. Some medication can also interfere with ejaculation.
Retrograde ejaculation is an uncommon condition that occurs when semen enters the bladder instead of going out through the urethra during ejaculation. The main reason for retrograde ejaculation is that the bladder neck does not close. This causes semen to go backwards into the bladder rather than forward out of the penis.
Retrograde ejaculation may also be caused by medical conditions such as diabetes, surgery to the prostate and medications. Injury can also cause retrograde ejaculation. Sufferers tend to notice that there is little ejaculate on orgasm and that their urine is cloudy. Treatment is by stopping any medication that may be causing the condition.
