After Googling for a few minutes I have found quite a bit of research on how cervical health of a female sexual partner can affect the male partner. I have found how male sexual partner health related to HPV can effect the female cervix. I have found information on how trans-men need to continue to have their cervix tested for medical issues. I haven't found any information on if chromosomal issues can cause cervices to be present in men.
Or is your point that trans-men have cervices and so not "only women have cervices"? If that is the argument you are making, that is fine. Though then I am not sure what you are arguing. But I will just accept your opinion if that is what it is.
