IVF malformation
Test tube baby refers to the baby that develops by cultivating embryos in the laboratory through in vitro fertilization technology and then transplanting them into the mother's womb. Although this is a great breakthrough in modern medicine, not all IVF babies can develop healthily. IVF malformation refers to the abnormalities that occur in the process of embryo transfer or pregnancy development. The following will elaborate on the manifestations and signs of IVF malformation from four aspects: fetal face, internal organs, limbs and nervous system.
Fetal facial abnormality
The abnormal facial features of IVF may include cleft lip, cleft palate, etc. Cleft lip means that there is a gap between the oral cavity and the nasal cavity, which makes the lip unable to close completely; Cleft palate means that the upper palate of the oral cavity is not fully closed, forming an opening between the oral cavity and the nasal cavity. These abnormal manifestations may be related to incomplete union or rupture of embryonic leaves during embryonic development.
In addition, IVF malformation may also lead to abnormal facial features and skull morphology. For example, abnormal facial features may be manifested as too small or too large eyes, too wide or too narrow eye distance, too small or too large jaw, etc. Abnormal skull shape may be manifested as abnormal head shape, such as flat head or deformed head.
Abnormality of internal organs
The visceral organs of IVF may also be abnormal. Among them, heart malformation is one of the common visceral organ abnormalities. Cardiac malformations include heart defects, cardiac structural abnormalities, etc., which may lead to cardiac dysfunction or arrhythmia. In addition, IVF malformations may also present kidney malformations, lung malformations, intestinal malformations, etc.
Renal malformation may be manifested as abnormal renal structure, renal dysfunction, etc. Pulmonary malformations may cause problems such as dyspnea and lung infection. Intestinal malformation may lead to difficulty in defecation, intestinal obstruction, etc.
Limb abnormality
IVF malformations may also have limb abnormalities, such as abnormal number of fingers or toes, and finger or toe malformations. The abnormal number of fingers or toes may be the phenomenon of more or less fingers, that is, the number of fingers or toes exceeds or falls below the normal range. Malformations of fingers or toes may be manifested as abnormal morphology, such as deformed nails, bent phalanges, etc.
In addition, abnormalities such as inconsistent limb length, hyperextension or hyperflexion of knee joint may also occur.
Nervous system abnormality
IVF malformation may cause nervous system abnormalities, including brain structural abnormalities and neurological dysfunction. Abnormal brain structure may be manifested as hydrocephalus, brain defects, etc. Hydrocephalus refers to the excessive accumulation of cerebrospinal fluid in the brain, resulting in brain swelling; Brain defect refers to the incomplete development of brain tissue. These abnormalities may affect the infant's intellectual development and neurological function.
Nerve dysfunction may lead to abnormal muscle tone and impaired motor coordination. Abnormal muscle tension is manifested as excessive muscle tension or looseness, which affects the infant's motor ability. Impaired motor coordination may lead to difficulties in coordinating infants' daily activities, such as walking and holding objects.
Summary
IVF malformations may involve the fetal face, visceral organs, limbs and nervous system. Fetal facial abnormalities include cleft lip, cleft palate, abnormal facial features and abnormal skull morphology. Abnormality of internal organs may lead to heart malformation, kidney malformation, lung malformation and intestinal malformation. Extremity abnormalities may include abnormal number of fingers or toes, deformity of fingers or toes, and inconsistent length of limbs. Nervous system abnormalities may lead to brain structural abnormalities and neurological dysfunction. For couples who are carrying out IVF, they need to understand and face these potential problems carefully, fully communicate with doctors, and be prepared for possible risks.
