Treatments to the cervix for cervical dysplasia and other problems include laser or cryosurgery (freezing), a cone biopsy or conization by cold knife, and LEEP (loop electrical excision procedure). These procedures can affect fertility and decrease your ability to get pregnant because they destroy cervical glands.
Cervical glands produce cervical mucus, which plays a role in fertility by enabling sperm to pass through the cervix. Insufficient or absent cervical mucus can prevent sperm from reaching the inside of the uterus.
A procedure called 'IUI' or intrauterine insemination can improve your chances of getting pregnant. A small catheter is placed through your cervix, bypassing the mucus, and sperm are injected directly into your uterus.
