How long is the IVF test valid?
IVF is a method of assisted reproduction through in vitro fertilization, which is widely used in infertile couples. In the process of IVF, examination is one of the most important links, but many people do not know the validity period of IVF examination. The validity period of IVF test is described below from different perspectives.
1. Validity period of pre inspection
In order to ensure the success rate and health of IVF, couples need to carry out a series of examinations before preparing IVF. These examinations include genetic examination, endocrine examination, reproductive system examination, etc. The validity period of these pre inspections is generally short, usually about one year. The reason for the short validity period is that the physiological and pathological state of the human body will change over time, so it is necessary to recheck before the IVF is officially carried out to ensure the most accurate results.
The main purpose of these pre examinations is to understand the health status of the couple, eliminate some genetic diseases or potential reproductive system problems, and make appropriate treatment preparations in advance. For example, if the woman has ovulation problems, drug treatment is needed to restore normal ovulation function. If the semen quality of the man is poor, some measures can be taken to try to improve the semen quality.
2. Period of validity of pregnancy cycle
In the process of IVF, there is a specific "pregnancy cycle", that is, the cycle when the woman's ovary abandons the egg. Generally speaking, after the completion of embryo transfer, the woman needs luteal support treatment to help maintain the stability of the endometrium and promote embryo implantation. This cycle is relatively short, usually around 2-3 weeks.
If there are no signs of pregnancy in the cycle, such as no signs of pregnancy or blood β- With the increase of hCG concentration, the IVF is likely to fail. In this case, the couple needs to re conduct the examination before IVF treatment, re evaluate the physical conditions of both parties and the most suitable treatment method.
3. Expiry date of embryo freezing
Embryo freezing is a common processing method in IVF. If several good embryos are obtained in one IVF process, but only a few are used for embryo transfer, the remaining embryos can be frozen. The validity period of these embryos is relatively long, usually between a few years and several decades.
Cryopreservation of embryos can provide more opportunities for patients to try, avoid the process of egg and sperm extraction required for every test tube baby, and also reduce the use of drugs. In addition, embryo freezing can help couples better control the number of their children and avoid multiple pregnancy caused by too many embryos transferred.
4. Validity period of eugenic embryo screening
In order to ensure the health of IVF and reduce the risk of genetic diseases, some hospitals provide eugenic embryo screening services. This screening method is generally to determine whether there is a risk of some genetic diseases in embryos by genetic testing of embryos. The validity period of this screening is relatively short, usually within a few months.
Eugenic embryo screening can help couples choose healthy embryos for transplantation, reducing the birth risk of chromosomal abnormalities and genetic diseases. However, because embryo screening requires time and accurate laboratory analysis, it is necessary to ensure the effectiveness of the results before deciding to use the screening results for transplantation.
Summary
The validity period of IVF examination varies according to different examination procedures. The validity period of pre examination is about one year, the validity period of pregnancy cycle is 2 to 3 weeks, the validity period of embryo freezing can be several years to decades, and the validity period of eugenic embryo screening is several months. The validity period of the examination can help couples better prepare and evaluate the treatment plan of IVF, improve the success rate and fetal health.
