Assignment:

A case-control study was conducted to determine if an association exists between workers in uranium mines and loss of fertility due to reduced sperm count. A group of 200 men with low sperm count were identified from clinics located in areas with uranium mines. Each selected case was matched with a randomly selected male control on the following factors: age, area of residence, and smoking status. What would be a good reason for matching in this case?

1. Men of the same age should have the same sperm count level

2. Smoking has no effect on sperm count so it should be the same among cases and controls

3. Previous studies have shown that there are age-related differences in low sperm count
