Women with cervical Nabothian cysts will not become infertile because of them.

Cervical Nabothian cysts are actually cysts of the cervical glands. Abnormal substances, such as squamous epithelium during the healing process, have entered the gland ducts, blocking them and preventing the contents of the cysts from escaping. They merely indicate the squamo-columnar junction of the cervix and do not affect the cervical canal or cause it to narrow, nor do they affect vaginal secretions or female infertility.

However, if a woman has a particularly large single cervical cyst or multiple cervical gland cysts, they may cause cervical hypertrophy. When the cervix is enlarged, there might be hyperplasia in the interstitial part and possible formation of fibrous tissue. This could potentially affect the dilation of the cervix during childbirth.
