Most smaller cervical polyps do not affect pregnancy. If the cervical polyp is larger and blocks the opening of the cervix, causing sperm to not be able to combine with an egg cell, it may interfere with a normal pregnancy. Cervical polyps are caused by inflammation or infection of the cervix, which stimulates the cervical glands or mesenchyme to proliferate and protrude towards the cervical opening. Generally, patients with cervical polyps do not have obvious specific symptoms, but a few patients may experience menstrual abnormalities, abnormal vaginal bleeding, and so on. Usually, cervical polyps do not have much effect on pregnancy, but larger cervical polyps may block the cervical opening, preventing the sperm from entering the uterus and combining with the egg, increasing the risk of infertility, and leading to the patient’s inability to get pregnant normally. It is recommended that the patient consult a doctor in time, to clarify the condition of the targeted treatment, to develop good habits in life, pay attention to rest, good personal hygiene, and follow the doctor’s instructions for follow-up.
