###Human: I have erectile dysfunction and ejaculation problems. Please advise. ###Assistant: Hi. I have gone through your query. I would like to know whether the amount of semen ejaculated had been the same over the last three years or has it decreased? Firstly, the speed with which the ejaculate came out does not unduly affect your fertility. I would suggest you have a semen examination if not done before to check for the sperm count which is more important. Secondly coming to your complaint, I would ideally like to do a full physical examination given your previous history. It could either be some blockage in the path of semen or the semen could be going back into the bladder. I would suggest you to visit your local urologist for a detailed clinical examination, an ultrasound to check if there is any blockage and a semen test to check for the volume and sperm count. Another possibility is incoordination of the muscles that normally gives the speed to the ejaculate, which cannot be tested to identify. As I said before, if your primary concern is to have a child, then I would suggest you to get a semen analysis first. If it is normal then you do not have anything to worry about.
