What are the main causes of cervical infertility?

Patient's question:

I haven't been pregnant for a year. I had cervical erosion, but I wanted a child before it was treated. What are the main causes of cervical infertility?

Doctor's answer:

I. Cervicitis-Induced Infertility
When cervicitis occurs, there is an increase in leukorrhea, and its color and odor differ from normal conditions. It may appear as white or yellow, viscous, purulent, and malodorous. This alters the vaginal environment, increasing the presence of toxins and inflammatory cells, which is unfavorable for sperm survival and movement. As a result, sperm cannot penetrate the cervix to enter the uterine cavity, leading to infertility.
II. How Abnormal Cervical Mucus Causes Infertility
The cervix and its canal glands are important target tissues for ovarian hormones. Their anatomical structure and cervical mucus secretion exhibit cyclical changes in response to the fluctuation of ovarian hormones, closely related to fertility.
