With the gradual opening of second and third births, many 40 year old women also want to have another child through in vitro fertilization technology. Currently, with the maturity of in vitro fertilization technology, the success rate of in vitro fertilization is also increasing. But female friends who still want to have children at the age of 40 need to hurry up and find hospitals and prepare for pregnancy, because after the age of 40, women's physical functions will continue to decline and become no longer suitable for childbirth.

Women over 40 still have a chance of successful pregnancy. Usually, the pregnancy rate of in vitro fertilization depends not only on age factors, but also on the hospital chosen by the patient. The technical level of the hospital. Their own physical condition. There are three factors that affect the success rate of in vitro fertilization:

1. Age infertility in couples is an important factor affecting the success rate of in vitro fertilization. The main reason is that ovarian function gradually decreases with age, and the risk of miscarriage also increases. The earlier the risk of premature birth and fetal malformations, the greater the likelihood of successful in vitro fertilization.

2. The physical condition of women includes the ovaries, uterine environment, and hormone levels in the body. It will affect the success rate of the test tube. Consciously improving physical fitness before undergoing in vitro fertilization can increase the success rate of in vitro fertilization.

3. Women in a good mood have a certain impact on in vitro embryo implantation. Due to the impact of long-term pregnancy failure, women are prone to emotional instability and endocrine abnormalities, which are not conducive to their health. Maintaining a relaxed and happy mood during the treatment cycle of IVF is beneficial for the treatment of IVF. If you decide to have in vitro fertilization as soon as possible, as long as you find the right way to have a child, don't blindly pursue others' successful experiences. I think your friend can spend less money on IVF. The dream of being pregnant and having a child now.

Older women who undergo IVF are more concerned about the success rate of IVF. In fact, there is no need to worry too much about this aspect and actively cooperate with doctors' treatment. For elderly women, the older they get, the less likely it is to undergo in vitro fertilization. On the one hand, women's ovarian function will continue to decline, and on the other hand, the quality of their eggs will gradually deteriorate. The decline in female ovarian function is irreversible. Most of the time, people define women over the age of 40 as elderly women, but in fact, this does not mean that women cannot conceive or have children. Women over the age of 40 simply say that the likelihood of natural pregnancy is lower than when they were young, and that abortion is necessary. The risk of premature birth and deformities is higher. According to relevant data, even at the age of 40.50 or even 60, there are successful pregnancies.

According to a review by the editor of 592 Baobao Network, in terms of the success rate of in vitro fertilization in China, the best reproductive age for women is between 25 and 28 years old; After the age of 30, the number of eggs in women is not as high as before; After the age of 40, female ovarian function decreases, egg quality gradually deteriorates, and gynecological diseases gradually increase, leading to a decrease in the success rate of in vitro fertilization. Generally speaking, the success rate after the age of 40 also greatly decreases. The success rate for women aged 25 to 40 is about 50% -60%, and the success rate for women over 40 is about 30%. Among women of childbearing age over 40 years old, the success rate is less than one tenth. Female friends must know that it is not easy for women to have children at the age of 40.
