Is IVF Baby at Risk at 35?
With the development of modern medicine, IVF technology has become a common way of reproduction. However, the risks and complications of IVF have always been concerned. Is the risk of IVF increased for 35 year old women? Next, this article will discuss this problem from many aspects.

Increased risk of egg quality decline
The quality of women's eggs is one of the key factors in giving birth to healthy babies. With the growth of age, the quality of female eggs will decline. According to statistics, the egg quality of 35 year old women may decline faster than that of 20 year old women. This means that during IVF, 35 year old women may need more assisted reproductive technologies, such as egg stimulation or egg donation.
In addition, the decline in egg quality will also increase the risk of chromosomal abnormalities. The risk of a 35 year old woman having children with Down syndrome is about one in 400, while in the 20 year old group, the proportion is only one in 1500. Therefore, 35 year old women need more chromosome abnormality screening and genetic counseling during IVF.
Reduced success rate of in vitro fertilization
An important part of IVF is in vitro fertilization (IVF). However, compared with young women, the success rate of in vitro fertilization of 35 year old women will be reduced. This is mainly due to the decline in egg quality and insufficient follicular development of 35 year old women. According to some hospital data, the success rate of in vitro fertilization for 35 year old women is usually only about 30% to 35%, while the success rate of 20 year old women can often reach more than 50%.
In addition, 35 year old women have an increased risk of embryonic malformation. Research shows that the embryo malformation rate of 35 year old women is about 25%, while that of young women is generally below 15%. Therefore, it is particularly important for 35 year old women to select the healthiest embryo in IVF.
Increased risk of pregnancy complications
Women aged 35 have a relatively high risk of illness during pregnancy. According to a study, pregnant women over 35 years old are more likely to suffer from pregnancy complications such as gestational diabetes, early pregnancy hypertension, gestational hypertension and pre eclampsia than young women. These complications will have a negative impact on the health of mothers and infants, which requires timely intervention and monitoring by doctors to ensure the smooth progress of pregnancy.
Increased risk of birth defects
In the process of IVF for 35 year old women, the risk of fetal birth defects is relatively increased. A study found that in IVF pregnancy, the probability of birth defects for women over 35 years old is about 5%, while that for women under 20 years old is only 3%. This also emphasizes the importance of fetal screening and routine prenatal examination for 35 year old women during IVF.
In summary, 35 year old women face relatively increased risks and complications in IVF. The decline of egg quality, the reduction of IVF success rate, the increased risk of pregnancy complications and the increased risk of fetal birth defects all need to strengthen medical intervention and attention. Therefore, for older women, it is recommended to consult a doctor in advance to comprehensively assess the risks and choose the most suitable reproductive mode.
