I've been peeking in now and then when I have time. GH does not affect fertility or cause DNA damage. I'm not sure where you got that info, but it simply is not true. The side effects as Mikeswift mentioned only happen from high dosages over an extended period of time. (Most of us don't have the money for that anyway.) Using GH at 5 iu per day for 4-6 months is a moderate cycle and shouldn't give you hardly any trouble at all if any. Do look at my log to see what I've been experiencing.
