Post-coital test to check normal values

The presence of sperm in the mucus.

Clinical significance of post-coital test

Abnormal results: The presence of sperm in the mucus indicates that the sexual intercourse method is correct. It is best to have 2l or more extremely active sperm in each high field of vision; it is good to have 6-20 very active sperm in each high field of vision; it is good to have 1-5 active sperm in each high field of vision Only a few inactive sperm are poor; those with no sperm are negative. There is no sperm or inactivity in the mucus. After the effects of poor sexual intercourse techniques and external lubricants are excluded, hidden male factors such as functional non-ejaculation, retrograde ejaculation or severe semen liquefaction must be considered. Immunity factors need to be paid attention to. For immune testing. There are 21 or more active spermatozoa in each high field of vision in the mucus, which means that the sperm count in the man's semen is at least 20000000 / ml, and there is sufficient reproductive capacity; the woman has sufficient estrogen production, and sufficient cervical mucus to store sperm The compatibility of sperm with cervical mucus is good. People to be examined: those who have functional ejaculation, retrograde ejaculation or severe semen liquefaction.

Precautions for post-coital test inspection

Unsuitable: Unknown. Contraindications before inspection: (1) The date of selective post-examination, the date of the inspection should be selected before and after the ovulation period. It can be measured according to bbt, at the lowest point before the temperature rise and within 3 days of each day before and after; or according to experience, 2-3 days in each month when the genitals feel moist and secretions increase. (2) Sexual intercourse at 22:00 to 23:00 the night before, and detection of cervical mucus from 8:00 to 9:00 the next morning. Requirements during the examination: Mucus is cloudy and the amount is small, which does not necessarily mean that the cervical canal can not produce mucus. The date may not be selected properly. Repeat the test after 48h or judge the ovulation date more carefully during the next menstrual cycle. Repeat this test.

After sexual intercourse test inspection process

The date is optional after the test. The date of the test should be selected before and after the ovulation period. Can be measured according to bbt, at the lowest point before the temperature rise and within 3 days of each day before and after; or according to the patient's experience, 2-3 days a month feel moist vagina, increased secretion. At this time, due to the stimulation of a large amount of estrogen, the high columnar epithelial cells in the cervical canal were slightly opened, and the cavity was filled with mucus. The appearance was like a pupil. The amount of mucus was more than 10 times the usual, and the water content was 92% -98. %, Sticky as egg white, which is most conducive to sperm penetration. Methods Sexual intercourse was forbidden for 2-3 days before the test, and there were more sexual intercourse examinations in the late evening or early morning of that day than within 2-8 hours after sexual intercourse. The vaginal dilator is not coated with lubricant. After the vagina is inserted into the vagina to expose the cervix, use sterilized and dry long forceps or a syringe with a plastic tube to reach 1 cm above the outer mouth of the cervix, and clamp or suck mucus. After removal, open tweezers in vitro to observe the degree of drawing of the mucus, or inject it on a glass slide and cover it with a cover glass, and then lift the cover glass to observe the degree of drawing of the mucus. When the ovulation period is near, the degree of drawing of cervical mucus should exceed 8-10cm. The cervical mucus was placed on a clean and dry glass slide, a cover glass was placed, and observed under a microscope at 400 times. For women of normal fertility, sperm can still maintain a certain vitality after staying in the cervical mucus for 4 days, so the test can be relaxed for testing 6-24h after sexual intercourse. Pepperell proposed to have sexual intercourse at 22:00 to 23:00 the night before and to detect cervical mucus from 8:00 to 9:00 the next morning. The depth of the material is not important, because the sperm distribution is uniform throughout the cervical canal after intercourse, so it is not necessary to take the material at a specific location, such as the cervix. Under normal circumstances, only sperm can enter the uterine cavity through the cervical canal after sexual intercourse, while the seminal plasma is left in the vagina. After intercourse, sperm quickly left the posterior fornix and entered the cervical canal, and the seminal plasma was discharged through the external vaginal opening. Therefore, semen overflow after intercourse is normal and not the cause. Mucus is turbid and has a small amount, but it is not because the date is not selected properly. It can be improved with a small dose of estrogen. For patients on the 28th menstrual cycle, they can be taken orally daily during the 5th to 13th days of the menstrual cycle. 0.0125mg of alcohol, 0.25mg of acetaminophen, or 0.625mg of estrogen to increase the amount of cervical mucus and improve its properties. Patients with severe cervicitis can be treated with laser or electric cautery after being tested negative for anti-cancer smears. The above treatment does not cause cervical stenosis, but it is more beneficial to pct or fertility because the inflammation is cured. There is no sperm or inactivity in the mucus. After the effects of poor sexual intercourse techniques and external lubricants are excluded, hidden male factors such as functional non-ejaculation, retrograde ejaculation or severe semen liquefaction must be considered. Immunity factors need to be paid attention to. For immune testing. If clomiphene is used as an ovulation-promoting treatment, its dose can effectively promote ovulation. However, those who make the cervical mucus thick due to clomiphene have an antagonistic effect on estrogen. Oral ethinyl can be taken orally 5 days after the drug is stopped. Alcohol 0.0125mg once daily for 7 days to increase the amount of cervical mucus and improve its texture.
