Can infertility be caused by chronic cervicitis?

Yes: Chronic cervicitis is an inflammation that can obstruct the cervix, blocking sperm. It can be treated with antibiotics. Insemination is often useful to bypass the obstruction.

Depends: Depends on what caused the chronic cervicitis. Often this is caused by an infection. Long term or under-treated bacterial cervicitis is associated with infertility as the infection can ascend to the fallopian tubes and thereby cause infertility.
