With the full liberalization of the two-child policy, many families want to take advantage of this opportunity to have another baby. However, some families want to have another baby with the help of IVF due to their age, so what should senior women pay attention to when doing IVF? For women over 40 years old who want to have a second child with IVF, they should be careful. This is because, for older women, their body functions are not as good as when they were younger, and as they age, the quality of their eggs is declining, making it more difficult to conceive a child. The risk of pregnancy is also high due to the high incidence of chromosomal abnormalities in older women, which can lead to premature births and miscarriages, as well as Down’s syndrome and other conditions that can greatly affect the growth of the child. From a medical point of view, women between the ages of 26 and 30 years old have the best functions for conception, so it is best to give birth at this stage. After this age, a woman’s fertility function decreases year by year, and the risk of having a child increases gradually. Therefore, patients who want to undergo in vitro fertilization should do so as early as possible so that their chances of success will be higher. Age is not a condition that absolutely controls fertility, some people are a little older but it does not exclude the possibility of good physical function, if the ovaries, uterus and other functions are good, there is still a possibility of fertility. Therefore, it is necessary to have a thorough examination before the procedure, and this is something that patients still need to pay attention to. IVF as an assisted reproductive technology for infertility, not all people are suitable for IVF, so a bit older women who want to do IVF need to be checked, whether they are suitable for IVF, not blindly, to do IVF need to meet the indications for IVF. At the same time age factor also affects the success rate of artificial assisted reproductive technology, if infertile patients want to do IVF, must be done before it is too late! IVF experts remind that in addition to wanting to regenerate before it’s too late, it’s best to go to the hospital to receive pre-conception checkups before preparing to get pregnant, to find out the problems and treat them as early as possible, and to recuperate for at least six months before planning to get pregnant, so that you may get twice the result with half the effort.
