Medical index and premise of IVF
Test tube baby is one of the important achievements in modern reproductive medicine. Through assisted reproductive technology, couples who cannot conceive naturally realize their desire to have children. The success rate of IVF depends largely on the satisfaction of a series of medical indicators and preconditions. The following will elaborate on the medical indicators and prerequisites of IVF from four aspects: embryo quality, maternal health, male sperm quality and hospital facilities.
Embryo quality
One of the core links in IVF technology is embryo quality. After in vitro fertilization, the embryo must be cultured and evaluated, and the embryo with the most growth potential and normal development must be selected for implantation into the mother's uterus. The appearance, number of cells, cytoplasm and genetic characteristics of embryos are the criteria for evaluating embryo quality. The success rate of IVF can be improved by evaluating the health and normality of embryos.
The key indicators of embryo quality include pronuclear cell (MPN), hexamethylated late embryo (LH) and blastocyst. The presence of prekaryocyte indicates the normal development of the embryo, the late embryo of Liujia has blastocyst cavity, and the blastocyst is the embryo that reaches the cyst stage. These indicators are important criteria to measure the quality of the embryo.
In addition, embryo evaluation also includes embryo chromosome karyotype and genetic disease screening. Chromosome abnormalities and genetic diseases may affect the normal development of embryos and pregnancy outcomes. Therefore, chromosome genetic analysis and screening of embryos in the process of IVF will help to improve the success rate.
Maternal health
Maternal health is critical to the success of IVF. Maternal age, ovarian reserve function, uterine condition, endometrial thickness, etc. will affect the development and pregnancy outcome of IVF.
Female age is one of the main factors affecting the success rate of IVF. Aging will lead to the decline of egg quality and the weakening of ovarian reserve function, making the pregnancy process more difficult. Especially for women over 35 years old, the success rate of IVF is low, which is prone to problems such as fetal termination and abortion.
The uterine condition and endometrial thickness also affect the success rate of IVF. Uterine malformation, endometriosis and other conditions will affect the implantation of embryos and pregnancy. The implantation rate will be reduced if the endometrium is too thin or too thick.
Male sperm quality
Male sperm quality is critical to the success of IVF. The number, vitality and morphology of sperm will affect the effect of fertilization.
Semen analysis is one of the methods to evaluate the quality of male sperm. Semen analysis measures sperm concentration, total number, vitality and morphology. The number of normal sperm should be between 200 and 30 million/ml, the vitality should be more than 40%, and the proportion of normal sperm should be more than 4%. If the number, vitality or morphology of sperm is abnormal, it may affect the fertilization process and reduce the success rate of IVF.
Hospital facilities
The success rate of IVF is also related to hospital facilities and technical level. Complete equipment, professional team, strict operation process and standardized management are all important conditions to ensure the success rate of IVF.
The hospital should have advanced assisted reproductive technology equipment, such as embryo incubator, IVF ultrasound instrument, etc. These devices can provide a good growth environment and improve the quality of embryo development.
The professional team of the hospital is also very important. The operation of IVF requires experienced doctors and technicians who can fully understand the patient's situation, develop personalized treatment plans, and track and test according to the patient's specific conditions.
In addition, hospital management is also the key to ensure the success of IVF. Strict operation process, standardized operation and management process can reduce the occurrence of medical errors and improve the quality of treatment.
summary
The medical indicators and prerequisites of IVF include embryo quality, maternal health, male sperm quality and hospital facilities. Embryo quality is mainly measured by evaluating appearance, cell number and cytoplasm. Chromosome karyotype and genetic disease screening are also important indicators for evaluating embryo health. Maternal age, ovarian reserve function, uterine condition and endometrial thickness all affect the success rate of IVF. The quality of male sperm includes the quantity, activity and morphology of sperm. Semen analysis is the key method to evaluate sperm quality. Hospital facilities should have advanced equipment, professional teams and standardized management, which are important conditions to ensure the success rate of IVF.
To sum up, the medical indicators and prerequisites of IVF are an important guarantee for the success of IVF. Only when these indicators and prerequisites are met, can the success rate of IVF be improved and more couples who cannot conceive naturally realize their dreams of fertility.
