What is a biochemical abortion?

A biochemical abortion is an early abortion that occurs within 5 weeks of pregnancy. An elevated hCG level can be detected in the blood, greater than 25 mlU/ml, or a positive urine pregnancy test, but no gestational sac can be seen on ultrasound, suggesting that the fertilized egg has failed to implant. Biochemical abortion may be related to poor quality of the embryo itself, such as chromosomal abnormalities, a way of natural selection to eliminate unhealthy embryos. It may also be related to maternal factors, such as endocrine disorders, poor endometrial receptivity, abnormal immune factors, etc., which may affect embryo implantation and development. However, if biochemical abortion occurs repeatedly, a comprehensive examination is needed, including chromosome examination of both husband and wife, endocrine examination of the woman, immune function examination, etc., in order to clarify the cause and take corresponding treatment measures to improve the success rate of subsequent pregnancy. Although biochemical abortion is less harmful to the body than other forms of abortion, it may still bring certain psychological pressure and distress to women, and appropriate psychological counseling and support are needed to make women correctly understand this phenomenon and reduce anxiety and anxiety.
