For an undisturbed ejaculation, an orderly interaction of nerve impulses and a normal condition of the male sexual organs is required. Disturbances or changes in one of these two parts can lead to a sexual climax (orgasm), but afterwards no seminal fluid comes out of the penis. In some cases, the seminal fluid empties into the bladder instead. This is called "retrograde ejaculation". Common reasons for this can be, for example, paraplegia or prostate surgery.

For these patients, it is still possible to obtain the sperm cells from the urinary bladder. To do this, the urine must first be made alkaline, otherwise the sperm cells will not survive in the acidic environment. There is a special medication regimen for this, which the patient must start a few days before ejaculation.

If you have retrograde ejaculation, talk to your urologist or to us, we will be happy to inform you about this procedure. We have developed a standardised procedure in our "Androzentrum an der Wien" that offers you the maximum chance of having a child despite the presence of retrograde ejaculation.
