There are several reasons that can lead to 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 are also different from normal conditions. It may appear as white or yellow, viscous, purulent, and malodorous. This alters the vaginal environment, leading to an increase in toxins and inflammatory cells, which are 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 morphology and cervical mucus secretion exhibit cyclical changes in response to the fluctuations of ovarian hormones and are closely related to fertility.
