post-coital test

The post-intercourse test is a test to test the penetration and compatibility of sperm into cervical mucus. First described by sims in 1966, and then promoted by huhner, it is also known as sims-huhnertest or huhnertest. The so-called post-intercourse test means that the couple undergo sexual intercourse during the period of ovulation. After a certain period of time (2~4 hours) after sexual intercourse, the mucous membrane inside and outside the cervical canal is taken for microscopic examination. Then, according to the results of the microscopic examination, the cause of infertility is determined. Therefore, post-intercourse trials are often used clinically as a means of detecting infertility. Basic Information Specialist classification: male examination check classification: semen and prostatic fluid examination Applicable gender: whether the male is fasting: not fasting Tips: The date should be chosen around the ovulation period. Sexual intercourse was performed from 22:00 to 23:00 the night before, and cervical mucus was detected from 8:00 to 9:00 in the morning. Normal value There is sperm in the mucus. Clinical significance Abnormal results: There is sperm in the mucus, indicating that the method of sexual intercourse is correct. It is best to have 2l or more extremely active sperm in each high field of view; 6 to 20 live sperm in each high field is good; 1 to 5 active sperm in each high field is good. Only a few inactive sperm were poor; those without sperm were negative. There is no sperm or inactivity in the mucus. Excluding the technical problems of sexual intercourse and external lubricants, it is necessary to consider the hidden male factors such as functional ejaculation, retrograde ejaculation or severe semen liquefaction. Test about immunity. There are 21 or more active sperm in each mucus in the mucus, which means that the sperm in the man's semen is at least 20000000/ml, which has sufficient fertility; the woman has enough estrogen to produce enough cervical mucus to store sperm. The compatibility of sperm with cervical mucus is good. People who need to be examined: functional non-ejaculation, retrograde ejaculation or severe semen does not liquefy. Precautions Taboo before inspection: 1. The date of the date after the selective exchange test should be selected before and after the ovulation period. It can be measured by bbb, within the minimum point before the rise of body temperature and within 3 days before and after each day of the body temperature; or according to experience, it is carried out within 2 to 3 days of the month when the genitals are wet and the secretions increase. 2, the previous night from 22:00 to 23:00 sexual intercourse, the next morning from 8:00 to 9:00 to test the cervical mucus. Requirements for examination: mucus turbidity, small amount, does not necessarily mean that the cervical canal can not produce mucus, may choose the date is not appropriate, can be repeated after 48h, or in the next menstrual cycle, more carefully determine the ovulation date, Repeat this test. Inspection process 1, date selection The date of the test after sexual intercourse should be selected before and after the ovulation period. The ovulation time can be determined by routine clinical or laboratory methods (basal body temperature, cervical mucus changes, hormone determination, etc.). At this time, the high columnar epithelial cells in the cervical canal are stimulated by a large amount of estrogen, the cervix is ​​slightly opened, the cavity is filled with mucus, the appearance is like a pupil, the amount of mucus is more than 10 times of normal, and the water content is 92%~98. %, sticky like egg white, is most conducive to sperm penetration. Sexual intercourse is prohibited for 2 to 3 days before the test, in order to have sufficient semen volume. After sexual intercourse, at least 0.5 to 1 hour should be placed (in order to prepare the semen into the vagina for sufficient time to liquefy and the sperm to have enough time to penetrate into the cervical mucus), the test should be carried out 2 to 8 hours after sexual intercourse (standard test). If the results of the first trial are satisfactory but still infertile, the trial should be repeated 18 to 24 hours after sexual intercourse (delayed trial). If at this stage there is a sufficient amount of active sperm in the cervical canal to suggest that mucus is appropriate, and the sperm can survive normally in the cervix, this excludes cervical factors that cause infertility. If the initial test results are not good, then the second test is performed 1 to 3 hours after the sexual intercourse (early test). 2, diagnosis method Collect cervical mucus specimens and observe the degree of drawing. The degree of drawing of cervical mucus should be more than 8~10cm when it is close to ovulation. The cervical mucus was placed on a clean, dry glass slide, covered with a coverslip, and observed under a microscope at 400 magnification. Under the microscope, 1-20 spermatozoa per high power field can be considered positive. It is generally believed that if there are more than 20 sperm per high power field, there is more chance of conception; no sperm is negative. Not suitable for the crowd Inappropriate people: not yet known. Adverse reactions and risks Nothing.
