Retrograde Ejaculation |
|
 |
In the condition of retrograde ejaculation, semen doesn't come out of the penis during ejaculation but instead enters the bladder. It can be caused by diabetes, certain medications, and surgery to the bladder, prostate, or urethra. Occasionally, this can be an organic physical problem. If retrograde ejaculation is caused by drugs, removal of the specific drug may resolve the condition. Retrograde ejaculation caused by or following genitourinary tract surgery may be responsive to the use of epinephrine-like drugs (such as pseudoephedrine or imipramine).

During normal ejaculation, the opening of the bladder (bladder neck) closes to prevent semen from entering as it passes through the urethra. In retrograde ejaculation, the bladder opening doesn't close properly. As a result, sperm is allowed to enter the bladder instead of being ejected out the tip of the penis. Therefore, in some cases, semen can be extracted from a urine sample given after ejaculation. |
