Age requirements for IVF
IVF is a kind of assisted reproductive technology. It is a method of transferring the fertilized eggs to a certain stage in the laboratory and then transferring them to the female uterus for pregnancy. However, compared with natural pregnancy, IVF has certain age restrictions.
First, women's age is one of the key factors in IVF success rate. It is generally believed that the fertility of women has declined significantly after the age of 40, and most hospitals limit the age of IVF to between 45 and 50 years old. This is because with the growth of age, women's ovarian function will gradually decline, and the number and quality of ovaries will decrease, thus reducing the probability of pregnancy and pregnancy. At the same time, increasing age will also increase the risk of chromosomal abnormalities, miscarriage, premature delivery and other risks for pregnant women, as well as the possibility of congenital diseases for newborns.
Secondly, the age of men also has a certain impact on the success rate of IVF. The study found that male fertility will also decline with age. Compared with young men, the sperm quality of older men may be reduced, including sperm quantity, vitality and genetic quality. Therefore, the age of men should also be taken into account when choosing IVF technology.
However, it should be noted that age is not the only factor that determines whether IVF is feasible. It is also necessary to consider other factors comprehensively, such as health status, living habits, genetic inheritance, etc. Therefore, before the IVF, it is recommended that both husband and wife go to the formal reproductive hospital for a comprehensive inspection to understand the individual's health status and pregnancy possibility.
Risk of IVF treatment
Although IVF treatment provides an opportunity for older couples to conceive children, it also has certain risks.
First, during in vitro fertilization, women may develop ovarian hyperstimulation syndrome (OHSS). OHSS is a disease caused by too many follicles, premature rupture and a large amount of fluid exudation. This situation is less likely to occur in IVF treatment, but it still needs attention.
Secondly, the success rate of IVF pregnancy is not high. According to statistical data, the IVF pregnancy rate of women over 40 years old is about 30% to 40%, and it gradually decreases with the increase of age. Therefore, even after IVF treatment, older couples still need to face possible failure and disappointment.
In addition, IVF also has the risk of miscarriage and premature delivery. Due to age and other factors, the risk of IVF suffering from chromosome abnormalities, fetal dysplasia and other problems will also increase.
Success rate of IVF and hospital selection
The success rate of IVF is affected by many factors, including age, ovarian function, sperm quality and hospital experience.
Age is one of the most important factors. Although the success rate of IVF decreases with age, the chance of success can also be increased by choosing a regular reproductive hospital and a suitable doctor, even if they are older. For example, Peking Union Medical College Hospital and Shanghai Jiaotong University Medical College Affiliated Obstetrics and Gynecology Hospital are well-known IVF hospitals in China, with rich experience and advanced equipment.
In addition to the choice of hospitals, ovarian function and sperm quality are also key factors in the success rate. If the female ovary function is poor or the male sperm quality is low, some auxiliary treatment methods may be needed, such as embryo quality assessment, hormone therapy, etc. Therefore, individualized treatment is also an important factor to improve the success rate.
conclusion
In general, although age has certain restrictions on IVF, it does not mean that older couples cannot try IVF technology. By choosing a formal reproductive hospital, understanding personal health status and following the doctor's advice, there is still a possibility of success. Especially with the development of modern medicine and technological progress, with the continuous development of science, the success rate of IVF technology will continue to improve.
Most importantly, age should not be the only factor in deciding whether to try IVF. Before making a decision, the husband and wife should fully understand the risks and possible adverse results of IVF, and fully communicate and discuss with the doctor. After all, for couples who want to become parents, IVF technology provides a valuable way for them to realize their dreams.
