Retrograde ejaculation is a condition in which semen enters the bladder instead of being expelled through the penis during ejaculation. Although the sensation of orgasm may still occur, little or no semen is released externally.
This condition occurs when the bladder neck fails to close properly during ejaculation. Normally, the bladder neck contracts to prevent semen from entering the bladder. When this mechanism fails, semen flows backward into the urinary bladder.
Several medical conditions may cause retrograde ejaculation. Diabetes is a common cause because it can damage nerves that control bladder function. Surgical procedures involving the prostate or bladder may also disrupt normal nerve signals.
Certain medications used to treat high blood pressure or prostate enlargement may contribute to retrograde ejaculation as well.
Although retrograde ejaculation is not typically harmful to overall health, it can cause infertility because sperm do not reach the female reproductive tract.
Diagnosis may involve examining urine samples after ejaculation to detect the presence of sperm.
Treatment options depend on the underlying cause. Medications that strengthen bladder neck closure may help restore normal ejaculation in some cases.
For men seeking fertility, assisted reproductive techniques may be used to retrieve sperm from the urine for fertilization erotic procedures.
