The success rate of IVF is related to female age

IVF technology is a way for infertile couples to have their own children through in vitro fertilization. However, the success rate of IVF is affected by many factors, one of which is the age of women. The success rate and female age of IVF will be described in detail from different aspects below.

Ovarian reserve and egg quality

Women's ovarian reserve and egg quality decline with age, which has a direct impact on the success rate of IVF. Young women have abundant ovarian reserves, more eggs to choose from, and these eggs are more likely to be of high quality. However, with the growth of age, the ovarian reserve gradually decreases, and the egg quality also decreases, leading to a lower success rate. According to statistics, the success rate of IVF for women under 35 years old is higher than that for women over 35 years old.

Doctors usually collect multiple eggs during IVF to increase the chances of fertilization and transplantation. However, for older women, fewer eggs were collected, which increased the complexity and difficulty of IVF.

Efficacy of ovulation promoting drugs

In the process of IVF, women need ovulation promoting drug treatment to increase the number of eggs. However, these drugs are less effective for older women than for younger women. In theory, ovulation promoting drugs can improve the quantity and quality of eggs, thus increasing the success rate of IVF. But in fact, for women over 40 years old, the effect of ovulation promoting drugs is limited, because their ovarian function has gradually declined.

Therefore, older women may need longer treatment cycles to achieve sufficient egg numbers, which further reduces the success rate of IVF.

Effect of embryo quality

In the process of IVF, the quality of embryos is also one of the determinants of success rate. Young women have better egg quality, healthier embryos formed after fertilization, and higher survival rate. Older women, however, have poorer egg quality and lower embryo quality after fertilization.

High quality embryos are the key to successful pregnancy. Doctors usually select the best quality embryos for transplantation after a few days of in vitro embryo culture. The decline in egg quality of older women means that the quality of transferred embryos may also be low, thus affecting the success rate of IVF.

Risk of pregnancy complications

Age also increases the risk of complications of IVF pregnancy, which also affects the success rate. Older women are more likely to have complications such as hypertension, diabetes and ectopic pregnancy during pregnancy.

These complications will not only bring risks to women's own health, but also may have adverse effects on the development and survival of the fetus. Therefore, with the increase of age, the success rate of IVF decreases, and the risk of pregnancy complications also increases.

Summary

In conclusion, the success rate of IVF is closely related to the age of women. Women's ovarian reserve and egg quality, the efficacy of ovulation promoting drugs, embryo quality and the risk of pregnancy complications will be affected with age. The success rate of IVF for older women is relatively low. Therefore, early birth planning is particularly important for couples who want to achieve their fertility aspirations through IVF technology.
