Is there a high probability of success in IVF at the age of 40? Many elderly couples, due to age issues, are too late to conceive naturally. When they think of IVF, they worry about whether IVF can still be successful after 40, and what is the probability? In fact, age is a key factor in the success of in vitro fertilization (IVF). Over the age of 40, the success rate of IVF significantly decreases, and some may require multiple attempts to achieve success. Let's take a look below.

As for IVF, older mothers have additional risks. The success rate for women over the age of 35 will decrease by half, while for women over the age of 40, the success rate is below 15%, and the abortion rate is particularly high. In addition, the failure rate of in vitro fertilization (IVF) for older postnatal babies is also relatively high, such as a significant increase in the probability of Down syndrome.

As an auxiliary fertility technique, IVF is mainly used to treat infertility caused by blocked fallopian tubes in women or low semen or poor quality in men. It is currently the treatment method for infertility. From the perspective of pregnancy preparation, those who have given birth to one child do not need to worry too much about insufficient reproductive function and blindly follow the trend to try in vitro fertilization technology. If the attempt to artificially conceive for one year is unsuccessful and the diagnostic criteria for infertility are met, assisted reproductive technology should only be considered when necessary under the comprehensive evaluation of the physician. However, doing IVF is not as simple as many mothers imagine, and assisted reproductive technology carries risks. Mothers who try to do IVF must use many ovulation promoting drugs.

In fact, even with IVF technology, the success rate of older mothers over the age of 40 is only 20%, which is basically half lower than the success rate of 40-45% under the age of 40. Although there is no certain age at which pregnancy is impossible, the harder the age, the greater the opportunity for pregnancy. There are many factors that can jeopardize the success of in vitro fertilization, such as over the age of 35, decreased uterine and ovarian reserve function, altered egg cell quality, increased probability of chromosomal variation, and reduced rate of in vitro embryo implantation, resulting in a low success rate

Through reading the article, we found that after 35, the probability of women becoming pregnant naturally or artificially decreases significantly. Natural pregnancy is more difficult to succeed, while artificial pregnancy still has a certain probability. However, by the age of 40, the success rate is only 20%, and the older the age, the lower the rate of conception. Therefore, we suggest that whether it is natural pregnancy or artificial in vitro pregnancy, it should be done as early as possible, not too late. If success cannot be achieved in China, We can also choose foreign IVF.
