Waiting

I have a friend who have been have been waiting for so long now to have their first child. They have been married for over 6 years already but until now they are still waiting. Some of our friends who have the same problem have been recently given the gift after their long wait but this friend remains hoping. He told me that his wife has been under medication for years now and he thinks that the problem might not be only his wife but as well as with him. He told me that one of his colleagues recommended a supplement for him but I told him to read get enough important testosterone supplement information before you buy because it might given him worst side effects. I cannot tell him anything to make comfort him because he has been pressured for so long now. But I can only help him pray that someday, their waiting will be over.
