Reasons for the low success rate of IVF
IVF is a kind of assisted reproductive technology. Although it has achieved success in many cases, it also has a low success rate. There are many reasons for the low success rate of IVF, including the following aspects:

1. Age factor
Female age is one of the important factors affecting the success rate of IVF. With the growth of age, the number and quality of female eggs will decline, leading to a reduction in the success rate of pregnancy and embryo embedding in the uterus. Especially for women over 35, the success rate is lower.
In addition to female age, male age may also affect the success rate of IVF. The quality and quantity of male sperm will also decrease with age.
2. Lifestyle and health status
Lifestyle and health status will also affect the success rate of IVF. Smoking, alcohol abuse, drug abuse, obesity and other bad habits and unhealthy lifestyles will reduce the success rate of IVF. In addition, some chronic diseases, such as diabetes and hypertension, will also adversely affect the success rate of IVF.
3. Internal conditions and uterine environment
The thickness and quality of female endometrium and the environment inside the uterus will affect the success rate of IVF. If the endometrium is too thin or too thick, it will cause difficulties for embryo implantation and development. Other structural abnormalities in the uterus, such as fibroids and polyps, may also affect the success rate of IVF.
4. Medical technology and operational factors
Medical technology and operation level will also affect the success rate of IVF. Including embryo culture technology, embryo selection and implantation methods. Doctors' experience and technical level will directly affect the success rate of IVF.
Other options after IVF failure
If IVF fails, couples can consider the following other options:
1. Retry
Test tube babies are not sure to succeed once. Couples can choose to try again. Re examine and evaluate possible problems, and carry out further treatment according to professional suggestions to improve the success rate of IVF.
2. Use of other assisted reproductive technologies
If IVF fails, try other assisted reproductive technologies, such as artificial insemination, in vitro fertilization, etc. Doctors will recommend appropriate assisted reproductive technology according to the specific conditions and problems of the couple to improve the chance of pregnancy.
3. Adopt surrogate mother
If both husband and wife are unable to conceive naturally, surrogate mothers can be considered. A surrogate mother is another woman who becomes pregnant and gives birth to a child, and then gives the child to the husband and wife.
4. Adoption
Couples who cannot succeed in IVF can also consider adopting a child. Adoption is a meaningful choice, which can give children without biological parents a warm family.
Summary
The low success rate of IVF may be caused by many factors, including age, lifestyle and health status, internal conditions, uterine environment, medical technology and operational factors. For couples who failed in IVF, they can consider retrying, adopting other assisted reproductive technologies, acting as surrogate mother or adopting. In the face of the low success rate of IVF, couples can make appropriate choices according to their own conditions and the doctor's advice to achieve their fertility aspirations.
