Physical condition of test tube baby after 28 days
In vitro fertilization (IVF) is a kind of in vitro fertilization (IVF) technology that completes the fertilization process in vitro, and then transfers the fertilized eggs to the mother's uterus. There may be some differences between the physical condition of IVF and that of naturally conceived infants. Next, we will elaborate on the physical condition of test tube babies after 28 days from four aspects.

Growth and development
There is no essential difference between the growth and development of 28 day IVF and naturally conceived infants. According to the study, the growth rate and weight gain of test tube babies after birth are similar to those of naturally conceived babies. Their height, weight, head circumference and other indicators will develop according to the normal growth trajectory. This means that after 28 days of IVF babies, they have begun to enter a rapid growth period, and muscles and bones will gradually form.
In addition, the development of nervous system in IVF is similar to that in normal infants. They will gradually develop sense organs such as vision, hearing and touch. Therefore, after 28 days, IVF can respond to light and sound, and even recognize the mother's voice.
health
In general, the health status of IVF infants after 28 days is similar to that of naturally conceived infants. The development process of IVF in the mother is not fundamentally different from that of naturally conceived infants, so they will not be more prone to some health problems because of IVF technology. However, since IVF babies may face some risks related to premature delivery, some hospitals will carry out additional monitoring and care for them.
After 28 days, most IVF babies have been able to feed normally and gain good weight. Their digestive system will also gradually develop and be able to absorb and digest breast milk or formula milk. The immune system of IVF will also gradually develop and begin to develop immunity to diseases.
psychological development
Psychological development is one of the important aspects of IVF after 28 days. IVF babies may experience some additional emotional and psychological pressure during the process of maternal fertilization and transplantation, which may affect their psychological development.
Research shows that the psychological development of IVF is similar to that of naturally conceived infants in most cases. They will gradually establish contact with their parents and the surrounding environment, and show their ability to adapt to the new environment. However, there may be some problems related to emotional regulation and distress, which need the common attention and support of families and doctors.
Follow up and nursing
IVF babies still need regular follow-up and care after birth. The hospital will arrange regular physical examination, vaccination, development assessment and other services to ensure their physical and health conditions. At this stage, families also need to provide good care and care to provide a safe and warm environment for IVF.
In conclusion, the physical condition of test tube babies after 28 days is similar to that of naturally conceived babies. They have normal growth, health and psychological development. Although there may be some additional risks and challenges in the process of IVF, with the progress of technology and medicine, the health of IVF has been better protected, bringing more hope to families.
