What are the manifestations of IVF?
IVF refers to the babies that are bred in the process of in vitro fertilization using artificial assisted reproduction technology. The performance of IVF can be observed and evaluated from many aspects, such as physiology, psychology, behavior and appearance. The common manifestations of IVF will be described in detail from these four aspects.

1、 Physiological performance
The physiological performance of IVF mainly includes birth weight, height, body shape, growth and development. Since embryo transfer or transfer of multiple embryos may lead to multiple pregnancies, the average weight and height at birth may be lower than that of naturally pregnant infants. However, as time goes by, the normal growth and development speed of IVF will gradually catch up with that of naturally pregnant infants of the same age, and generally reach the same weight and height as naturally pregnant infants around one year old.
In addition, IVF babies may face some physiological problems after birth, such as premature delivery, hypoglycemia, respiratory infection, etc. Most of these problems are caused by maternal health during pregnancy, interference factors in the process of embryo cultivation or embryo transfer technology. However, with the continuous development and improvement of medical technology, the incidence of these problems has been greatly reduced.
2、 Psychological performance
The psychological performance of IVF babies refers to their emotional, personality and intellectual characteristics during their growth. Due to the difference in the birth mode between IVF and naturally conceived infants, some studies believe that IVF may be psychologically different. However, the existing research results do not clearly prove that there are significant psychological differences between IVF and naturally conceived children.
Like natural pregnant children, IVF will also be affected by family and social environment, and their personality and intelligence will be shaped by various factors. Therefore, the psychological performance of IVF mainly depends on their growth environment, education methods, personal talents and other factors.
3、 Behavior
The behavior of IVF babies refers to their behaviors, actions and activity habits in daily life. Compared with naturally conceived children, the behavior of IVF may be affected by different education methods and growth environments.
It has been observed that IVF babies often show a high curiosity, desire to explore and curiosity. They may be more sensitive to the surrounding environment and more willing to actively participate in various activities. In addition, IVF babies may also show strong adaptability and tenacity. These characteristics may be caused by the particularity of IVF birth process.
4、 Appearance
The appearance of IVF is not significantly different from that of naturally conceived infants. There is no significant difference in appearance between IVF and naturally conceived infants in terms of facial features or body structure. IVF is genetically closely related to parents or sperm donors, so their appearance is often closely related to biological kinship.
In conclusion, the performance of IVF can be evaluated from the aspects of physiology, psychology, behavior and appearance. Although IVF babies may face some physiological problems at birth, their growth and development speed will gradually catch up with that of naturally conceived infants of the same age over time. In terms of psychology, behavior and appearance, there is no significant difference between IVF and naturally conceived infants. Their characteristics are more affected by family and social environment. Test tube babies are an important achievement of medical technology. Through scientific cultivation and monitoring, they will be able to grow healthily and happily.
