Introduction
Biochemical pregnancy is an abnormal pregnancy, typically referring to a transient rise in serum human chorionic gonadotropin (hCG) following fertilization. However, the fertilized egg fails to implant in the uterine cavity and instead regresses or is expelled due to retrograde tubal transport or impaired uterine peristalsis, thus not developing into a viable embryo. Additionally, women experiencing a biochemical pregnancy often present with amenorrhea, manifesting as delayed or postponed menstruation.

Biochemical pregnancy is an abnormal form of pregnancy, typically referring to a transient rise in serum human chorionic gonadotropin (hCG) following fertilization, when the fertilized egg fails to implant properly in the uterine cavity and instead regresses or is expelled before further development into a viable embryo. Women experiencing a biochemical pregnancy often present with amenorrhea, manifesting as delayed or missed menstrual periods.

There are various causes of biochemical pregnancy, including viral infections such as cytomegalovirus, toxoplasma, and herpes simplex virus, which may contribute to this condition. Certain autoimmune disorders can also increase the risk. When preparing for pregnancy again, it is important to inform your doctor about any history of biochemical pregnancy so that appropriate evaluations and tests can be performed to identify potential causes and reduce the risk of recurrence, including further biochemical pregnancies, spontaneous abortions, or embryonic arrest.

Under normal circumstances, with proper recovery and调理 after a biochemical pregnancy, future conception is generally unaffected. Therefore, patients need not experience excessive stress and can actively take preventive measures to minimize the risk of biochemical pregnancy.
