What are the main items checked in cervical mucus examination? Cervical mucus examination mainly checks the following items:

1. Appearance: After the menstruation is over, the cervical mucus is small in quantity, thick and turbid. The closer to the ovulation period, the more cervical mucus is secreted, the thinner and more transparent it becomes. It returns to its original state after ovulation.

2. The amount of cervical mucus reaches a peak value of about 0.3 ml one day before the body temperature rises, and decreases rapidly 1-2 days after the body temperature rises.

3. Wire drawing test: Apply the mucus on a dry glass slide, touch the mucus with a corner of another glass slide, and then gently pull it upwards to observe the maximum length of the wire drawing. The degree of drawing increases gradually after the end of menstruation and can reach up to 10-20cm during the ovulation period.

4. Crystallization of cervical mucus: Apply the mucus on a glass slide and dry it naturally. Observe it under a low-power microscope. Due to the high salt properties of the mucus, it appears as typical fern-like or imbricate crystals with many branches. Atypical are dendritic and coarse fern-like. Generally, crystals begin to form 8 days before the body temperature rises. The closer to ovulation, the more typical and obvious the crystals are. Estrogen promotes the formation of crystals, while progesterone and androgen have an inhibitory effect.

5. Cytology shows that there are very few cells in the cervical mucus during ovulation, about 0-3 white blood cells per high-power field of view. If the number of white blood cells is large at this time, inflammation of the cervical canal and above should be suspected.

6. Anti-sperm antibodies can be detected in the cervical mucus of some patients with immune infertility.

7. Chemical composition analysis of cervical mucus shows that the pH value, protein, sugar, mucin, chloride and other contents also show periodic changes.

The significance of cervical mucus examination:

1. Predict ovulation and guide conception: The effect will be better if ovulation is estimated and the conception date is selected in conjunction with basal body temperature and vaginal exfoliated cell examination.

2. Early pregnancy: If the smear is all ellipsoids without fern-like crystals, it indicates pregnancy.

3. Amenorrhea: Cervical mucus undergoes periodic changes, indicating that the ovaries are functioning well and the cause of the disease is in the uterus.

The above is an introduction to the main items checked in cervical mucus examination. From the above introduction, we can understand that there are many items in cervical mucus examination. These items can check whether the examinee has gynecological diseases, and the results of the examination can also be used to guide conception!
