Routine examination for IVF

IVF is a kind of assisted reproductive technology. For those couples who cannot conceive naturally due to fertility disorders, IVF technology is an important method. In the whole process of IVF, routine examination is very important, which can not only ensure the health of mothers and infants, but also improve the success rate of pregnancy. This article will elaborate on the routine examination of IVF from four aspects: gynecological examination, male examination, genetic disease screening and embryo health assessment.

1. Gynecological examination

The first step of IVF is to have a gynecological examination of the woman. On the second to fourth days of a menstrual cycle, women need to undergo gynecological examinations to assess whether the thickness and shape of the endometrium are suitable for embryo implantation. In gynecological examination, doctors will conduct vaginal palpation, cervical smear, endometrial biopsy and other examinations. In addition, water test of fallopian tube is also needed to ensure that the fallopian tube is unobstructed. These examinations can help determine whether the patient has endometriosis, fallopian tube blockage and other diseases, as well as eliminate cervical erosion, cervical infection and other factors that may affect the success of pregnancy.

2. Male examination

IVF technology requires not only women to be examined, but also men. Male examination mainly includes semen analysis and sperm DNA fragmentation detection. The semen analysis can evaluate the concentration, vitality, morphology and other indicators of male sperm, and determine whether the quality of sperm is suitable for embryo transfer. Sperm DNA fragmentation detection can detect the degree of sperm DNA damage in men, which is of great significance for evaluating the survival rate of embryos and the success rate of pregnancy. The male examination can assess the male's spermatogenic function and fertility, and help doctors to develop appropriate assisted reproductive treatment programs.

3. Genetic disease screening

In the process of IVF, genetic disease screening is a very important step to reduce the risk of genetic diseases before embryo implantation. Genetic disease screening includes genetic disease history investigation and gene testing of both spouses. By consulting the family genetic history of the couple, doctors can know whether there are genetic diseases that need to be screened, such as thalassemia, cystic fibrosis, etc. At the same time, gene testing can be carried out to exclude the possibility that both spouses carry genetic disease genes. Through genetic disease screening, the risk of carrying genetic disease genes can be found in advance to avoid passing on genetic diseases to the next generation.

4. Embryo health assessment

Embryo health assessment is the last step of IVF to ensure the health and development potential of the implanted embryos. In the process of embryo culture, doctors will conduct a series of evaluations on embryos, including morphological evaluation, pre implantation genetic diagnosis and genomics testing. Through morphological evaluation, doctors can judge the quality and development of embryos and select the most likely embryos to be implanted successfully. Preimplantation genetic diagnosis can detect the genes of embryos and exclude embryos with chromosome abnormalities and single gene genetic diseases. Genomic detection can further understand the chromosome number and structural abnormalities of embryos. These assessments can improve the pregnancy success rate of IVF and reduce the risk of embryo implantation failure. To sum up, IVF needs routine examinations such as gynecological examination, male examination, genetic disease screening and embryo health assessment. These tests are critical to ensure the patient's health and pregnancy success. Through comprehensive and systematic examination, doctors can help formulate appropriate treatment plans, improve the success rate of IVF, and realize the fertility aspirations of patients.
