Although Cystic Fibrosis does not cause sexual impotency, it can lead to fertility problems. In most men with CF, the tubes that carry sperm are blocked, which causes infertility.
Impotency can have a number of causes. Some are psychological -- anxiety or fear, for example. Some are biological and can be serious, such as blood circulation or nerve problems. If the teen is otherwise healthy, I would suspect anxiety, which is perfectly normal although annoying. A doctor can do tests to find out if there is a health reason behind it, and there are medications and procedures to resolve them.
yes it does. there is research that supports this!
