roaccutane vs infertility

Hi! im 25 years old and all my life i havent had a single acne on my skin... but now, i have been having a hard time with treating my acne.i already took doxycycline but it's not working.i have been told by my doctor that I should be on Ro-accutane...I am thinking that since i am in the middle east right now due to my work,  my acne would just fade out..im scared that if i take ro-accutane, i would be infertile for the rest of my life.ive heard cases that those who are in ro accutane did not conceive years after because of this medication...what are the chances of being infertile?thanks.
