The optimal reproductive age is from the perspective of eugenics. It is important and necessary to pay attention to the role of age, and selecting the optimal reproductive age is scientific, which can improve the quality of fertility and eliminate adverse factors. The optimal age combination for male and female fertility should be around 7 years older for males than females. The optimal reproductive age for women is between 23 and 30 years old, while for men it is between 30 and 35 years old. It is best not to exceed 30 years old for women and 35 years old for men. The summary of the editor on 592 Baobao website is that 36 years old is already considered an elderly postpartum woman. When doing IVF, it is necessary to pay extra attention to maintenance and safety.

What is the success rate of elderly women undergoing in vitro fertilization?

The success rate of in vitro fertilization technology has been a challenge since transplantation, but it is also difficult to understand. Generally speaking, one out of 10 couples will successfully conceive. For those who use in vitro fertilization technology, one out of three couples will successfully conceive. This means that through in vitro fertilization technology, we can increase our chances of pregnancy by 200%. But sometimes patients fail on their first attempt at IVF technology. If this happens, we will try a second or third time. Typically, 75% of couples become pregnant in the second or third cycle. For the remaining 20%, we either give them some advice or try their technology.

Generally speaking, a fertilized embryo forms four cells after two to three days and is implanted into the uterus. However, in the case of previous in vitro fertilization treatment failure, the embryo will be cultured in the laboratory for approximately five days until it becomes 150 cells and then implanted into the uterus. This increases the likelihood of smooth embryonic development. Another way to improve pregnancy opportunities after the failure of the first cycle of in vitro fertilization is to use frozen embryos produced in the first cycle in the second cycle, as these embryos increase the chances of successful pregnancy.

Although the success rate of pregnancy in elderly women is lower than that in young women, in vitro fertilization can still increase the likelihood of pregnancy. Generally speaking, the necessary factors for pregnancy are embryo, uterine environment, etc. If these aspects are not too bad, the resistance to pregnancy will be very small. Secondly, congenital abnormalities are an unavoidable problem that we cannot avoid. The fetus is influenced by many factors during its development. We can only try to pay attention to various details during pregnancy and avoid abnormalities.
