In brief: Yes

There is a decline in sperm number and function as a man gets older. However, there are usually some sperm present throughout a man's life.
There are higher rates of birth defects also after age 50. A swedish population study showed a young woman married to a young man has a higher chance for conception than a young woman married to an older man.
