Age limit of test tube babies for women and children
IVF technology is a great achievement of modern medicine, but age has certain restrictions on the success rate and safety of IVF for women and children. The following is a detailed description of the age of women and men.
Female age limit
The age of women is one of the important limiting factors for IVF. With the growth of age, the quality and quantity of female eggs gradually decline, which leads to a decrease in the success rate. Generally speaking, the success rate of IVF for women under 35 years old is higher, while women over 35 years old face a higher risk of failure. Therefore, age is an important consideration when choosing IVF technology.
However, not all women over 35 years of age cannot have IVF. The doctor will make a comprehensive assessment based on individual conditions, including ovarian function, uterine conditions and other factors, to determine whether it is suitable for IVF. Older women may need more treatment cycles and higher hormone doses to achieve better success rates when carrying out IVF.
In addition, older women also increase the risk of chromosomal abnormalities. Older pregnant women are prone to chromosomal abnormalities in children, such as Down's syndrome, so it is particularly important to do chromosomal screening for embryos.
Male age limit
The age of men also has a certain impact on the success rate of test tube babies for women and children. Although male fertility is relatively stable, the quality and quantity of sperm will gradually decline with age. Some studies have shown that when men are older than 40, they may increase the risk of children suffering from autism and other neurodevelopmental disorders. Therefore, the age of men also needs to be considered in IVF technology.
There are relatively few age restrictions for men. Generally speaking, men can carry out IVF technology within the age of 65. However, men's physical condition and fertility should also be considered, such as sperm quality, semen parameters and other factors.
Physical condition limitations of test tube babies for women and children
In addition to the age limit, the physical condition of the mother and child IVF will also affect the success rate and safety. The following three aspects will be discussed.
Female physical condition limit
The physical condition of women is crucial to the success rate of IVF. Women with abnormal ovarian function, uterine malformation or other reproductive system related diseases may affect the implementation of IVF. For example, endometriosis, polycystic ovary syndrome and other diseases will affect the quality of eggs and the implantation of fertilized eggs, thus increasing the risk of IVF failure.
Male physical condition limit
The physical condition of men will also affect the success rate of IVF. For example, when men have abnormal sperm quality, semen parameters or other reproductive system related diseases, it may lead to the failure of IVF. Male infertility may be related to testicular disease, abnormal ejaculation and other factors, which will directly affect the quality and quantity of sperm.
Matching of couple's physical conditions
For test tube babies, the matching of the couple's physical conditions is also an important factor. The success rate of IVF can be improved only by the factors in the couple's physical conditions that should not affect each other. For example, if women have a certain disease and the same disease as men, it may increase the risk of embryonic development. Therefore, when choosing IVF technology, the matching of the couple's physical conditions is one of the factors to be considered.
summary
Maternal and child IVF is a complex and sophisticated technology, and age and physical condition are important limiting factors. The female age limit mainly aims at the decline of egg quality and quantity, while the male age limit mainly aims at the decline of sperm quality and quantity. At the same time, the physical conditions of women and men will also have an impact on the success rate of IVF, and related reproductive system diseases need to be considered. In addition, the matching of the couple's physical conditions is also one of the factors to be considered. Therefore, the above factors should be comprehensively considered when selecting the technology of test tube baby for women and children to find the most suitable scheme.
