DefinitionBy Mayo Clinic staff
Retrograde ejaculation occurs when semen enters the bladder instead of emerging through the penis during orgasm. Although you still reach sexual climax, you may ejaculate very little or no semen. This is called a dry orgasm. Retrograde ejaculation isn't harmful, but it can cause male infertility.
Retrograde ejaculation can be caused by medications, health conditions or surgeries that affect the nerves or muscles that control the bladder opening. If retrograde ejaculation is caused by a drug you're taking, stopping the drug may be an effective treatment. For retrograde ejaculation due to a health condition or as a result of surgery, treatment with drugs may restore normal ejaculation and fertility. But treatment for retrograde ejaculation is generally only needed to restore fertility.
