Success rate of very old childbearing
With the development of social economy and people's constant pursuit of quality of life, more and more women choose to delay childbearing, and the number of ultra elderly pregnant women is also increasing. However, the success rate of ultra old childbearing is affected by many factors, including women's age, physical condition, birth history, etc. Different pregnancy aid methods will also have a certain impact on the success rate.
Success rate of natural pregnancy
Natural pregnancy refers to the condition of pregnancy without using any assisted reproductive methods and relying entirely on the natural ovulation cycle. However, with the growth of age, female fertility declines, and the success rate of natural pregnancy will also decrease. According to statistics, the pregnancy success rate of women over 35 years old is only about 5% each month, while that of women over 40 years old is only about 1%. Therefore, the success rate of natural pregnancy of ultra old women is low.
Although the success rate of natural pregnancy of ultra old women is low, some women can still successfully conceive under natural conditions. This mainly depends on women's physical condition, ovulation and other factors. Women can improve the chance of natural pregnancy by monitoring the ovulation cycle and choosing an appropriate time to have sex.
At the same time, we should also pay attention to maintaining good living habits, including reasonable diet, moderate exercise, reducing staying up late, etc., to create a good physiological environment for natural pregnancy.
Success rate of artificial insemination
If the success rate of natural pregnancy is low, women can choose artificial insemination as a pregnancy aid method. Artificial insemination is a method of injecting sperm directly into a woman's uterus or cervix to improve the chance of pregnancy. For very old women, it is very important to choose the appropriate sperm source and high-quality sperm quality. At present, some reproductive hospitals use donated sperm for artificial insemination to provide high-quality sperm to improve the success rate of pregnancy.
According to statistical data, the success rate of artificial insemination is about 15%. However, the success rate will still be affected by women's age, physical condition and other factors. The older the woman is, the weaker her ovarian function will be, which will affect the quality of fertilized eggs and the ability of implantation. Therefore, the success rate of artificial insemination for ultra old women is not high.
In addition, artificial insemination still has certain risks, including ectopic pregnancy, multiple pregnancy, etc. When choosing artificial insemination, women should fully understand the relevant risks, follow the doctor's recommendations, and strictly implement the operation process.
Success rate of in vitro fertilization
Compared with artificial insemination, in vitro fertilization is a more common method of assisted pregnancy. In vitro fertilization includes IVF, embryo transfer and other technologies. In the ultra elderly women, in vitro fertilization is usually a better choice to improve the pregnancy success rate.
The success rate of IVF mainly depends on many factors, including egg quality, sperm quality, embryo quality, etc. High quality embryos can be screened and the success rate of implantation can be improved through such steps as egg taking, sperm separation, in vitro culture and embryo transfer. According to the current data, the success rate of IVF is about 30% to 40%.
Selection of assisted pregnancy methods
In addition to the above methods of assisted pregnancy, ultra elderly women can also choose some assisted pregnancy methods to improve the success rate of pregnancy. For example, ovulation promoting drugs can help women ovulate normally and increase the chance of pregnancy. For women with endometriosis and other problems, endometrial transplantation and other technologies can also be selected for treatment.
However, different assisted pregnancy methods have different degrees of improvement in the success rate, which needs to be selected according to the guidance of doctors and personal conditions. At the same time, the physical condition, economic ability, psychological endurance and other factors should also be taken into consideration when the ultra elderly women choose the method of assisted pregnancy.
To sum up, the success rate of ultra old childbearing is affected by many factors, including women's age, physical condition and the choice of assisted pregnancy methods. The success rate of natural pregnancy is low, the success rate of artificial insemination is medium, and the success rate of in vitro fertilization is high. Through reasonable selection of assisted pregnancy methods and under the guidance of doctors, it can increase the chances of successful pregnancy for ultra old women.
