Bicycle Ergometer / Wheel - Harmful To The Female Genitals?

I have a question - is the ergometer/cycling harmful to the genitals in women? I had read in an article that it was very harmful to women, because of the "friction" itself, it could lead to deformation, enlargement of the labia minora, etc. I have been using an exercise bike for years and I have not had any problems, but the things which I read I was very scared and did not dare to go up. Do you think that it is possible for something like this to happen and that it can affect women in some bad way? I only ask for serious opinions.
