Three abnormal phenomena of cervical plug

Cervical plug and cervical mucus are a kind of mucus secreted from the cervix. During a woman's pregnancy, cervical mucus can block the cervical opening to prevent bacteria from entering the uterus and having a certain impact on the development of the fetus. The normal volume of a cervical suppository is between 0.03ml and 0.71ml. Whether it is too much or too little, it is abnormal and needs to be adjusted in time. Below, I will introduce to you three abnormal phenomena of cervical plug.

1. Too little cervical mucus secretion

Cervical mucus plug is a very sticky, colorless or yellow transparent thick liquid secreted from the cervix. This is a special protective substance produced by people during pregnancy. When a woman is pregnant, the cervix will become softer and longer, and the mucus plug will be secreted to block the opening of the uterus, that is, the opening of the cervix. Otherwise, bacteria will enter the uterus and affect the normal development of the fetus.

If the amount of cervical mucus during ovulation is <0.03ml, it can be diagnosed as hyposecretion. When the cervix is ​​poorly developed, it is often accompanied by underdeveloped cervical glands, leading to poor normal secretory function. It may also be due to acquired injuries such as cervical cone resection, which destroy a large number of cervical glands, causing the cervical mucus to be secreted in small amounts and very viscous during ovulation. There are also some patients who cannot be diagnosed with the above-mentioned congenital or acquired factors, but have poor cervical mucus secretion, which most scholars believe is caused by estrogen receptor deficiency.

2. Excessive cervical mucus secretion

If the amount of cervical mucus measured once during the ovulation period is ≥0.71ml, or the amount of colorless and transparent cervical mucus is >0.41ml for more than 3 consecutive days, it means excessive mucus secretion. The main reasons are: chronic cervicitis, high estrogen levels, polycystic ovary syndrome, etc.

3. Presence of anti-sperm antibodies

It has been found both at home and abroad that when antibodies exist on the surface of cervical mucus or sperm, they lose the ability to penetrate cervical mucus and move, and instead exhibit oscillation locally. In recent years, research on anti-sperm antibodies has found that when the wife's serum antibody is positive, the positive rate in cervical mucus is higher, and when the serum is negative, positive results can also be detected in cervical mucus. Therefore, it is believed that the local cervix can also be stimulated by sperm antigens to produce antibodies.
