What tests should be done during IVF?
IVF is a kind of assisted reproductive technology, which can help those couples who cannot conceive successfully due to fertility barriers to achieve their reproductive dreams. This process requires a series of examinations to ensure women's health and improve the success rate of IVF. The following is a detailed description of what tests should be done in IVF process from four aspects.
1. Reproductive hormone examination
In the process of IVF, reproductive hormone test is essential. First, women need periodic blood tests to confirm whether they are ovulating. Then, the female ovarian function was evaluated by detecting the levels of estrogen and progesterone in the blood. These levels of reproductive hormones are crucial for determining the optimal time for oocyte retrieval and determining the appropriate dosage of ovulation promoting drugs.
In addition, men also need to have a reproductive hormone test to assess the quality and quantity of sperm. Common inspection items include measurement of testosterone, sperm analysis and genetic factors, which are helpful to determine appropriate fertilization methods and optimize pregnancy opportunities.
2. Ovarian ultrasound
Ovarian ultrasound is one of the common items in IVF. Through the vaginal ultrasound probe, doctors can observe the growth and number of follicles in the ovary, and evaluate the ovarian function. This helps to determine the best time and number of eggs to be retrieved, so as to improve the success rate of IVF.
In addition, ultrasound can also evaluate the thickness and quality of endometrium to determine whether it is suitable for embryo implantation. If the endometrium is not thick enough or of poor quality, additional treatment may be required to prepare the endometrium.
3. Ultrasonography of testis
Testicular ultrasound is an important examination for men, which is used to evaluate testicular structure and function. The volume, shape and blood circulation of testis can be observed by ultrasound. This is helpful to judge the male fertility, find the problem of normal sperm production, or eliminate the possible problems such as reproductive tract blockage.
In addition, ultrasound can also help doctors locate the operation points in the process of sperm extraction and egg retrieval, and improve the accuracy and safety of surgery.
4. Genetic examination
In the process of IVF, genetic examination is a necessary step to prevent or reduce the transmission of possible genetic diseases to the next generation. Genetic examination is mainly divided into gene carrier screening and embryo chromosome genetic examination.
The screening of gene carriers is carried out for both husband and wife. By detecting the pathogenic genes of common genetic diseases, we can judge whether there is genetic disease risk. If one or both of the couples carry the same pathogenic gene, the doctor will give advice according to the specific situation, including possible genetic counseling or selective embryo screening.
Embryonic chromosome genetic examination is carried out in the process of embryo culture. Embryonic cells are taken for gene detection to screen for chromosomal abnormalities in order to select healthy embryos for transplantation. This helps to avoid the risk of embryo implantation failure, abortion or birth defects caused by chromosome abnormalities.
Summary
The examination items involved in IVF include reproductive hormone examination, ovarian ultrasound examination, testicular ultrasound examination and genetic examination. The purpose of these examinations is to assess the function of the reproductive organs of both men and women, the quality and quantity of eggs and sperm, and the risk of genetic diseases. These examinations can provide important basis for the smooth progress of IVF process, improve the success rate and reduce the risk.
