EARLY PREGNANCY FACTOR Meaning and
Definition
-
Early pregnancy factor refers to a protein substance that is detected in a woman's blood shortly after conception and implantation of the fertilized egg in the uterus, indicating the beginning of pregnancy. This factor is produced by the trophoblasts, which are the outer layer cells of the developing embryo after it attaches to the uterine wall.
The early pregnancy factor functions as an immunomodulator, meaning it affects the immune system. It is believed to suppress the action of the mother's immune system, preventing it from recognizing the embryo as a foreign body and rejecting it. This is crucial for successful implantation and the continuation of pregnancy. The presence of early pregnancy factor can be measured through blood tests, and its absence or low levels may indicate a higher risk for miscarriage or implantation failure.
While the exact mechanism of action of early pregnancy factor is not fully understood, it is thought to play a role in creating a more tolerant environment in the uterus, allowing for the survival and growth of the developing embryo. It is also believed to be involved in the modulation of maternal immune responses, reducing the immune system's reactivity to the fetus.
Overall, early pregnancy factor is a protein substance detected in a woman's blood during early pregnancy that is involved in suppressing maternal immune responses and supporting the successful implantation and development of the embryo.
