Hormonal Regulation
Human Chorionic Gonadotropin (hCG): Once implantation occurs, the cells of the developing placenta begin to secrete hCG, the hormone detected by pregnancy tests. This hormone also helps maintain the corpus luteum and its production of progesterone, crucial for sustaining the pregnancy.
Timing and Location Implantation typically occurs about a week after fertilization. The preferred site of implantation is the posterior or anterior wall of the uterus.
Potential Complications
Ectopic Pregnancy: If implantation occurs outside the uterus, usually in a fallopian tube, it results in an ectopic pregnancy, which can be life-threatening.
Implantation Failure: Failure of the embryo to implant is a common cause of infertility or early pregnancy loss.
Significance in Pregnancy
Successful implantation is essential for a viable pregnancy.
The process establishes the physical connection between the mother and the developing embryo, enabling support and growth throughout pregnancy.
