What can cause a yellowish colour in semen?

The ejaculate comes from the underside of the prostate and sometimes when you get older and have to have that finger probe done they can in fact push on it a little to hard and make some come out. I have read that it is good to clean out the system now and then because it becomes molten or old. So it need moved now and then. Your body makes more all the time. Older men because their ejaculate id old may have some of spring that good have some health problems. Something like with women the older they become the more likely the child will have downs or other health related issues. So there is nothing wrong with masturbating now and then if you are not having sex on a regular bases it keeps the sperm fresh.
