Relationship between success rate of IVF and 40 year old women
IVF is a kind of assisted reproductive technology, which helps many couples realize their dreams of childbearing. However, with the growth of women's age, the success rate will also be affected. This article will discuss the possibility of success of 40 year old women as IVF from four aspects: age, ovarian reserve, egg quality and IVF technology.
1. Age
Age is one of the key factors affecting the success rate of IVF. The fertility of women decreases with age. As women are over 35 years old, the number and quality of eggs will decline. According to the statistics of Boston Children's Hospital, the success rate of 40 year old women in IVF is about 10% to 20%, while the success rate of women under 30 years old is about 40%.
For 40 year old women, the number and quality of eggs will be significantly reduced, so the success rate is low. This is because the ovarian reserve of 40 year old women has decreased, and the quality of the remaining eggs may decline, thus affecting the success rate of fertilization and embryo implantation.
In addition to the number and quality of eggs, 40 year old women may also have other health problems, such as hypertension, diabetes, etc. These health problems may further reduce the success rate.
2. Ovarian reserve
Ovarian reserve refers to how many eggs can be fertilized in a woman's ovary. The ovarian reserve will decrease with age, so the ovarian reserve of 40 year old women is relatively low.
In order to evaluate the ovarian reserve, doctors usually carry out the anti shell antigen (AMH) test. This test can assess the quantity and quality of eggs in the ovary. If the ovarian reserve is low, the success rate will be correspondingly reduced.
Some hospitals, such as Columbia University Medical Center in New York City, USA, conduct AMH testing before IVF, and use this result to develop personalized treatment plans to improve the success rate.
3. Egg quality
Egg quality is also an important factor affecting the success rate of IVF. The decrease of egg quality may lead to the decrease of fertilization rate, embryo development rate and implantation rate.
According to the data of Cornell Medical Center in New York City, the egg quality of 40 year old women is twice that of 30 year old women, which may lead to a decrease in the success rate.
However, not all 40 year old women have very low egg quality. Everyone's constitution and genetic factors are different, so some people may have relatively good egg quality and still have the chance to successfully carry out IVF.
4. In vitro fertilization technology
IVF technology includes IVF and embryo implantation. With the continuous progress of technology, the success rate of IVF is also increasing.
The core of IVF technology is the process of egg extraction and fertilization. At present, minimally invasive ovarian stimulation and egg retrieval techniques are mainly used, which can maximize the quality and quantity of eggs.
In addition, the choice of embryo implantation timing will also affect the success rate. Doctors usually choose the best time for embryo implantation according to the condition of eggs and embryos to improve the success rate.
summary
In general, the success rate of 40 year old women doing IVF is relatively low. Age, ovarian reserve, egg quality, IVF technology and other factors will affect the success rate.
Although the success rate is low, it is not totally hopeless. Some hospitals and experts have improved the success rate of 40 year old women by developing personalized treatment plans. Therefore, for 40 year old women, it is vital to consult a doctor as soon as possible and actively take appropriate treatment plans.
