My name is Dan. I am 37 years old and have had Hydrocephalus since I was 18 months of age. My wife and I have a beautiful almost 3 year old daughter, and I have been trying to get my wife pregnant again for over a year. Last summer I was in the hospital for a month and a half for a shunt malfunction but there is no clear cut time when the shunt started to break down so we think because of my behavior at the time that it was starting to break down 3-4 months before I went in the hospital. Does anyone on this list know of any studies linking shunt malfunction to low sperm count or can give me the name of a resource to guide me in the right direction?
