Why do preconception tests? What are the reasons why a normal pregnancy test cannot be successfully conceived?

Xiang Xiang (pseudonym): "Qiao'er, are you preparing for pregnancy and doing a preconception test?"

Qiao Er (pseudonym): "Preconception test?" Didn't do it, eat folic acid every day now, and then just wait for natural conception"

……

Xiangxiang: "I feel that I still need to do a preconception test, which will not only improve the chance of conception, but also help the health of the fetus." ”

Qiao Er: "No need, didn't our parents do it when they gave birth to us before, we are not as healthy and healthy." ”

I believe that the vast majority of people have such a thought, feel that natural conception is not good, and there is no need to do preconception tests, even my friends around me, most of them are naturally conceived. Why is there always a strong emphasis on the need for preconception testing? Why is preconception test recommended?

First of all, let's briefly understand the time of preconception examination, preconception examination is generally within 3 to 6 months before pregnancy, so that not only can timely understand the physical condition of both husband and wife, but also have sufficient time to adjust the body, thereby improving the probability of conception and fetal quality.

Preconception examination is not only to understand the physical condition of both husband and wife, but also to determine the probability of conception and determine the health of the fetus, thereby reducing the risk of fetal malformations and congenital diseases. In addition, according to the woman's physical condition, you can also develop a set of suitable pregnancy preparation and fetal maintenance programs, so as to reduce the risk of miscarriage and ensure the physical safety of pregnant mothers.

Before the rash encountered such a couple, is to consult what are the items of preconception examination, I believe that the screen before the preparation of pregnancy parents have certain doubts about the preconception examination items, next we let's take a look at it!

What are the items of preconception testing?

Items of examination for women:

Weight check: If the girl who is trying to conceive is heavier, there may be high blood pressure, diabetes and other phenomena; Underweight can reduce the chance of conceiving, so weight checks are also important for women who are trying to conceive.

Vaginal discharge examination: Vaginal discharge examination is mainly to check the properties of trichomoniasis, chlamydia, and mycoplasma in women, and negative is suitable for pregnancy. On the contrary, it is not suitable for pregnancy. Reminder: Do not have sex for 24 hours while having a vaginal discharge test.

Vaginal ultrasound examination: This examination is mainly to check the health of the uterus, whether there are symptoms such as uterine fibroids and uterine mediastin, as well as to check the size of the ovaries and whether there are ovarian cysts. In addition, women also need to undergo blood routine examination, electrocardiogram, blood pressure, sex hormones and other tests.

Male examination items:

Routine semen testing: This test is done to detect the number of sperm, the motility of sperm, and the density of sperm in men. General advice: Men do not have sex for a week before a semen test.

Blood routine examination: Men do blood routine examination before trying to conceive, mainly to detect mycoplasma, chlamydia, blood sugar, liver and kidney function, hepatitis series, syphilis, AIDS and other conditions.

Chromosomal examination: This test is done to detect whether both husband and wife have a genetic disorder, thereby reducing the risk of fetal malformations and congenital diseases. If abnormalities in the chromosomes are found during the examination, a test tube can be used for conception.

Through the above article, everyone has a certain understanding of preconception tests and why it is recommended to do pre-pregnancy tests. I believe that at this time, everyone will have such a thought in their hearts, natural conception is good, where there are so many deformed, defective newborns. Is this really the case? On August 24, 2021, a reporter from the Beijing Xinhua News Agency reported that according to the data released by the China Disabled Persons' Federation, in recent years, there have been nearly 900,000 cases of newborn defects in the mainland every year.

Bad pregnancy behavior: Women have bad living habits during pregnancy, such as staying up late, eating unhygienically, unhealthy, and too old or too young, taking drugs during pregnancy and other behaviors caused by newborn defects

Genetic abnormalities in either parent: If the mother or father has a mutation in the gene or the chromosome abnormalities, there may be a neonatal defect, so to reduce the probability of neonatal defects, you need to perform preconception tests.

The fetus is affected by the surrounding environment in the abdomen: such as environmental pollution, long-term inhalation of second-hand smoke by pregnant women; Bad parental behavior, such as radiation caused by long-term mobile phone play, staying up late, and the emotions of pregnant women, can affect the fetus in the abdomen.

Therefore, the corresponding examination between pregnancies can reduce the chance of newborn defects. So is it possible to have a successful pregnancy as long as you have a preconception test? No, before encountering such a patient, half a year ago the couple underwent a preconception test, and the test results were normal, but they could not successfully conceive, so what are the main reasons for this phenomenon?

No room is used during ovulation

If everything is normal before pregnancy, but the conception is not successful, it may be that the ovulation period is not calculated well, so the best time to conceive every month is missed. Therefore, if you want to improve the chance of conception, choosing to have intercourse during ovulation has a certain decisive role. So how should the ovulation period be calculated? For women with a more normal menstrual period, the ovulation period is generally about 14 days before menstruation, and everyone can borrow ovulation test strips to accurately calculate the ovulation period.

The psychological burden is too large, and there is a fear of not being able to conceive successfully

"Fear of getting pregnant before marriage, fear of not being able to conceive children after marriage" is a common idea among modern young people. Therefore, under this invisible pressure, it is possible to affect the chances of conception. Therefore, it is recommended that everyone relax their hearts and treat pregnancy with a normal heart, and may be able to successfully conceive a healthy baby.

Excessive number of sexual activities, affecting sperm quality

In order to improve the chance of conception, some young people will have sex many times, which will affect the quality of male sperm, thus reducing the chance of conception. It is generally recommended that couples during pregnancy do not have frequent sex.
