Testosterone and fertility??

Hey guys I'm Adryan (they/he) I get really bad random body dysmprphia and it sucks really bad, as far as I know I'm gender fluid and I don't wanna be a mad or be super masculine but I def want bottom growth and more androgynous futures so I'm assuming id either have a lower dose or be on T for a shorter time BUT THE POINT IS I really really wanna be a parent one day I want to have a baby of my own someday (not that there is anything wrong with adopting but it isn't my #1 choice) but I just recently realized that if I do as planned and as soon as I don't need parental permission I get on T it COULD fuck with my fertility and according to Google in some cases make you infertile and I was wondering if anyone had any personal insight or possibly have useful information that I probably couldn't find though simple googles, Ig I'm just really scared I'll have to choose between the two to some extent ..
