Fertility??? Please help.

What does the male and female have to go through to see if our bodies are capable of having a baby?? I have been only TTC for 4 months. But I figured I should get tested and my husband as well to see if we can even have a child before waiting a year...so we do not waste too much time. My husband is much older then me and I am already 30 so we do not want to be trying for a year to then find out there was something we could have done to fix it. So can anyone give me advice on what a male has to do to get tested?? And the same for me?? Thank you.
