I'm a severe asthmatic who has been on fourteen different medications including high doses of oral steroids and inhaled steroids. I have not been off the systemic steroids in over a year, and most months averaged 35 mgs a day. I'm on two inhaled steroids (Advair 500/50 one puff BID and Qvar 80mcg four puffs BID). I'm not too worried about the inhaled steroids as I am in the systemics. Will these high doses of systemic steroids inhibit my fertility as I get older? If it's of any use, I'm an eighteen-yr-old female, five foot six (169.8 cm), 140 lbs (63.5 kilos), normal menses and I am not sexually active. I have no health problems aside from this really severe asthma. I am being seen at National Jewish and I'm on IVIG to try and cut at the steroids. I have a low normal bone density. My FEV1 is consistently in the fourties. Is it possible that all this prednisone/medrol use can make me infertile?
