Introduction to IVF success rate

IVF technology is a kind of assisted reproductive technology, which aims to help couples who cannot conceive naturally achieve their reproductive aspirations. However, the success rate of IVF surgery is not fixed, it is affected by many factors. This article will analyze the success rate of IVF surgery from multiple perspectives.

Relationship between age and success rate

One factor closely related to the success rate of IVF surgery is the age of women. Young women generally have a higher success rate because their eggs are of better quality. According to the data of Beijing Maternity Hospital, the success rate of IVF for women aged 25-34 years old is about 40-50% on average, while that of women aged 35-40 years old drops to 30-40%. With the growth of women's age, the success rate of IVF surgery will be further reduced.

Age also has a certain impact on men. The study found that the success rate of IVF in the elderly group of men over 60 years old was significantly lower than that in the normal control group. Therefore, age is an important factor in the success rate of IVF surgery for both men and women.

Effect of egg quality

IVF is required for IVF, so the quality of eggs is one of the key factors for success rate. Egg quality is affected by many factors, such as age, ovarian function, follicular development status, etc. Specifically, if women have fewer eggs or abnormal follicular development, the success rate of IVF will decline. The research of Nanjing Union Medical College Hospital shows that poor egg quality is one of the important reasons for IVF failure.

Importance of embryo quality

Embryo quality is also one of the key factors that determine the success rate of IVF surgery. The quality of embryos is affected by the quality of fertilized eggs, culture conditions and the time of embryo transfer. In IVF surgery, selecting high-quality embryos for transplantation can significantly improve the success rate. For example, the research of Ruijin Hospital affiliated to Shanghai Jiaotong University found that PGD (embryonic chromosome detection) screening was carried out for 5-day embryos, and the proportion of embryos with normal chromosomes selected for transplantation was high, and the success rate was also high.

In addition, the number of embryos will also affect the success rate. Research shows that the success rate of two embryo transfer is higher than that of only one embryo transfer. However, multiple embryo transfer will also increase the risk of multiple pregnancy, which needs to be weighed under the guidance of doctors.

conclusion

In conclusion, the success rate of IVF surgery is affected by many factors. Women's age, egg quality and embryo quality are key factors. The success rate of young women and women with better egg quality is higher, and the success rate can also be improved under the condition of good embryo quality. However, the success rate will vary depending on the situation of each person. If couples consult a doctor before IVF surgery, conduct a comprehensive examination and evaluation, and follow the doctor's recommendations, the success rate of IVF surgery can be improved.
