In vitro fertilization (IVF) is currently an important assisted reproductive technology. Although this technology can improve women's fertility, it has certain age requirements for women. So at what age is it suitable for women to have IVF? In fact, it is ideal for women to undergo in vitro fertilization before the age of 35. Over the age of 40, the success rate is very low. If you are a woman over 40, you need to be prepared for failure.

We know that human fertility gradually decreases with age. Men are slightly better, while women's fertility is closely related to age. Generally, women are between the ages of 25 and 30, which is the best age for women to have children. After 35 years old, their fertility will significantly decrease because after 35 years old, the quality and quantity of eggs will significantly decrease, Ovarian function, embryo implantation rate, and pregnancy rate will significantly decrease, while the risk will gradually increase, such as the incidence of genetic abnormalities in embryos, miscarriage rate, and so on.

Generally speaking, women's natural fertility ability at the age of 35 is only half that of 25, while the fertility ability at the age of 36 to 38 is only a quarter of that at 25, and the fertility ability at the age of 39 to 40 is only 5% of that at 25. This means that among women aged 40, only 5 out of 100 can conceive naturally. Therefore, most women over 40 need to use assisted reproductive technology to conceive, while over 45, women have almost no natural fertility, The use of IVF may not necessarily lead to success.

In this situation of advanced age, it is difficult for women to conceive naturally, and the probability is very low. Even if some elderly women use IVF technology, the success rate may be higher than natural conception, but timely IVF is not omnipotent, especially over the age of 40, the success rate of IVF is only 20%.

Age is certainly an important factor affecting female fertility, but it also needs to be analyzed in a specific case. Some women who are well cared for have a high success rate in IVF, while women who are well cared for have a higher quality of embryos, a good endometrial environment, and a good quality of male sperm. These factors are all important factors that affect fertility. Of course, the younger the woman, the better these factors are.

There is a close relationship between whether a woman is suitable for IVF and their age. The earlier the IVF technique is, the better. As a woman, age is important, but age is irreversible. If you have indeed reached the age and youth stage, you should also have a positive attitude and actively cooperate with doctors for treatment, perhaps there is still hope of becoming a mother.
