Two consecutive biochemical pregnancies are considered to be caused by embryonic factors, female factors and male factors.
1. Embryonic causes: Embryonic factors are the most common causes of biochemical pregnancy, which are related to chromosomal abnormality. Chromosomal abnormality leads to the failure of normal development of the embryo, and biochemical pregnancy will occur.
2. Female factors: If the woman is older, the embryo quality will also decline, causing biochemical pregnancy. If the woman has some endocrine diseases, such as polycystic ovary syndrome, diabetes mellitus, it will affect the hormone level in the body, and it will be easy to have a biochemical pregnancy.
3. Male factor: if the male sperm quality or chromosomal abnormalities, there will also be poor embryonic development, biochemical pregnancy.
The causes of biochemical pregnancy are many, if there are two consecutive biochemical pregnancy, you should go to the hospital in time, after clarifying the cause of standardized treatment.
