Elbows for use with a bath exhaust fan

I'd like to ask if using a 90 degree elbow directly connected to the fan discharge opening of a bath exhaust fan would cause an air flow problem. I've read there must be at least 12 inches of straight run before any bends, and also that in certain circumstances, it doesn't make any difference. Thank you for all replies.

Would be best to have it down line some. A long radios should be ok.
