Yes. Male age affects both fertility and genetic disorders. Basically, sperm don't work as well as males age, but the drop off in terms of fertility is slower than for women. In terms of genetic factors, sperm works slightly differently than eggs do. While women are born with all of their eggs and these eggs age/expire eventually, sperm replicates constantly. As it replicates the risk that it will replicate genetic coding incorrectly increases. Meaning, the more it replicates the more errors occur, so the older a man is, the more errors his sperm has. This impacts fertility, the risk for miscarriage, and the risk for genetic disorders. Some genetic errors are more commonly associated with male sperm replication errors, and some more commonly with egg replication errors. Of course, overall health, as well as strong genes have a lot to do with how fast your body ages. Some people are fertile longer, and some not. I am having my first pregnancy/baby at 39 with absolutely no past or current problems, genetic or otherwise. 35 is generally not considered old for a man, or really even for *most* women. If you are having problems, it could be for any number of reasons, but your doctor will be able to tell you more after testing. I guess it depends how long you have been trying. Based on your age, I wouldn't worry until after a year of trying has passed, but that's just me.
