With the promotion of the three-child policy, many women over the age of 40 have ignited the desire to be mothers again. However, it is plagued by decreased fertility. More and more elderly mothers are eyeing the third generation of IVF, the means of assisted reproduction. So what is the test tube success rate of this?
First of all, we have to admit that human fertility is inversely proportional to age, and secondly, if you want to perform IVF surgery in a public hospital in China, you need to pass a preoperative physical examination and meet the surgical requirements in order to obtain the qualification for IVF surgery.
The success probability of 40-year-old women doing test tubes is directly linked to the specific situation of the body's reproductive organs, and the ovarian function of the average woman will decline sharply around the age of 35, when the eggs produced by the ovaries will be reduced in both quality and quantity. In this case, it will bring great limitations to the doctor's treatment plan and medication policy, due to the aging of the ovaries, so that the drug can not obviously stimulate the ovaries, the effect of treatment will also be discounted.
There is also a huge challenge due to the decline in egg quality, which can lead to a low success rate of egg fertilization, a decrease in the probability of pregnancy, and an increase in the probability of miscarriage. At the same time, with the increase in the probability of chromosomal abnormalities, the probability of newborn defects will also increase. Pre-transplant genetic screening also requires more detail.
Beyleng fertility said that overall, the risk of IVF after 40 will definitely be higher than that of young women.
