WHAT ARE THE CAUSES OF A BIOCHEMICAL PREGNANCY?
Although several potential causes have been put forth, the precise reason or relationship is still unknown. The following are two of the most typical contributing factors:
- Genetics: More and more data suggests that a woman’s genetic makeup is critical for good embryo development. There are two proposed mechanisms for early embryo loss. To begin with, when cells divide, the chromosomes that carry genetic material do not separate equally. Second, the early embryo may not be able to continue growing and developing due to an unknown cause. In other words, abnormal genetic material in the egg or sperm might occur before conception or even after fertilization in the early phases of embryo development.
- Endometrial thickness and pattern: caused by biochemical processes may be correlated with the thickness and pattern of the uterine endometrium. There is no evidence linking this to mother age or prior miscarriages. The levels of the hormones estradiol or luteinizing hormone (LH) on the day of the HCG trigger with fertility treatments or LH surge are not connected to biochemical pregnancy or clinical spontaneous miscarriage. Therefore, it is impossible to determine which pregnancies will result in a healthy pregnancy and which pregnancies will miscarry by examining hormone levels prior
to conception.
