Most women do not have any adverse effects on their fertility from treatment of dysplasia. This can increase chances of miscarriage or preterm labor. This is still unusual and can be treated. It is very rare for treatment to cause narrowing of the cervical canal to the point that sperm cannot get through causing infertility. The moral of the story is that routine paps not only protect your life but your fertility as well.
Fibroids are benign tumors of the uterus and have nothing to do with cervical cancer.
