What tests are needed for cervical infertility?

Patient's question:

I've always had pain downstairs in the same room, and it's been this long without getting pregnant. After checking, it was said to be cervical inflammation.

Doctor's answer:

I. Vaginal Examination
This examination can observe the shape of the cervix, the size of the external os, the amount of secretion, and whether phenomena such as cervical erosion are present. Additionally, attention should be paid to the absence of cervical motion tenderness and parametrial tenderness. Corresponding cervical canal mucosal bacteriology testing should also be performed. If necessary, a smear examination can be conducted.
II. Probe Examination
This is simple and practical, used to determine the direction, length, and proportion of the cervical canal relative to the cervix, as well as the presence of stenosis, adhesions, and the tightness of the cervical os. For cases suspected of abnormalities, further contrast examination should be considered.
III. Cervical Mucus Examination
This test primarily assesses the condition based on the secretion status of cervical mucus, i.e., whether the cervical mucus is secreted normally. It also involves observing the compatibility between cervical mucus and sperm, as well as checking for the presence of antisperm antibodies in the cervical mucus.
