Examination of IVF

Test tube baby is a kind of assisted reproduction technology, which is often used to solve the problem of infertility. In the whole process of IVF, examination is a very important link. This article will elaborate the contents and methods of IVF examination from four aspects: embryo evaluation, hormone examination, gene examination and reproductive tract examination.

1. Embryo evaluation

The embryo evaluation of IVF is one of the key links to ensure a successful pregnancy. Embryo evaluation mainly includes two aspects: embryo morphology evaluation and embryo genetics evaluation. The evaluation of embryo morphology is to observe the appearance and internal structure of the embryo through a microscope to evaluate its development and quality. The doctor will observe the cell number, cell arrangement and the morphology of the embryo membrane to ensure the normal development of the embryo. Embryonic genetic evaluation mainly includes the screening of chromosome abnormalities and single gene genetic diseases. Common methods include centromere identification, structural variation analysis and gene mutation screening. These assessment methods are aimed at screening healthy embryos and reducing the birth risk of deformed infants and genetic diseases.

2. Hormone examination

Hormone test is one of the important steps in the IVF process, which is mainly used to evaluate the reproductive hormone level of women and coordinate hormone therapy. Common hormone test items include serum estrogen, progesterone, luteinizing hormone and ovulatory stimulating hormone. These examinations can help doctors determine the functional status and hormone level of women's ovaries, and then adjust the hormone treatment program to improve the success rate. Hormone tests are usually performed before treatment, during treatment and before transplantation.

3. Gene testing

Gene testing plays an important role in IVF, mainly used to screen disease genes and genetic abnormalities that may be passed on to offspring. Commonly used gene detection technologies include polymerase chain reaction (PCR), gene chip technology and gene sequencing. These technologies can help doctors find couples with genetic disease risks early, and take corresponding measures to reduce the risk of disease. Gene detection plays an important role in IVF, which can not only improve the success rate of pregnancy, but also avoid some genetic diseases.

4. Reproductive tract inspection

Genital tract examination is an essential step before IVF, which is used to assess the condition of female reproductive tract and diagnose diseases that may affect pregnancy. Common genital tract examinations include ultrasound, hysteroscopy and salpingography. Ultrasonography can observe the morphology and structure of ovary and uterus, hysteroscopy can reveal endometrial abnormalities and organ structure problems, and salpingography can check the patency of fallopian tubes. The genital tract examination can determine whether the patient's reproductive organs are normal and whether there are diseases that are not conducive to pregnancy, so that doctors can formulate more accurate treatment plans.

summary

The test tube baby examination is an important link to ensure a successful pregnancy. Embryo evaluation, hormone test, gene test and reproductive tract test are common inspection items in the process of IVF. Embryo evaluation mainly includes embryo morphological evaluation and embryo genetic evaluation, aiming at screening normal and healthy embryos. Hormone examination is used to evaluate the reproductive hormone level of women and adjust hormone treatment plan. Gene testing helps screen genetic disease risks and reduce disease risks. Reproductive tract examination can evaluate the condition of female reproductive tract and diagnose diseases that may affect pregnancy. To sum up, the examination of IVF includes many aspects. Through detailed examination and evaluation, the success rate of IVF can be improved and the risk of possible genetic diseases can be reduced.
