Physiological feelings of IVF after implantation
The development of IVF technology has brought hope to couples who cannot conceive naturally. In the process of IVF, the embryo is implanted into the mother's uterus after several days of in vitro culture. This process is called implantation. After IVF implantation, the embryo will experience a series of physiological changes, including overcoming the resistance of the uterine wall during implantation, establishing nutrition supply channels, etc. At the same time, pregnant women may also have some physiological feelings.
1. Embryo feelings during implantation
Implantation is a key step in the development of IVF. Embryos need to overcome the resistance of the mother's uterine wall in this process. Embryos will produce adhesion molecules that can adhere to the endometrium. During implantation, the embryo will destroy the endometrium by releasing enzymes, making itself "embedded" in it, and forming a structure between the endometrium and the embryo. At the same time, the embryo will also set up a nutrition supply channel to facilitate nutrient exchange with the mother. This process usually occurs within 7 to 10 days after embryo implantation. These changes in the mother's body are the basis for the smooth development of IVF.
During implantation, some embryos may be affected by implantation failure. In this case, the embryo may be excluded from the uterus, leading to the failure of IVF. However, implantation failure is not rare, which does not mean that couples cannot try again, and doctors can provide improvement strategies according to the specific situation.
2. Symptoms that pregnant women may feel
After implantation, pregnant women may feel some symptoms physically. Although everyone's experience may be different, some common symptoms include breast pain, breast enlargement, nipple sensitivity, and slight abdominal distension. These symptoms are mainly caused by changes in progesterone.
In addition, some pregnant women may have slight vaginal bleeding after implantation, which is called implantation bleeding. This bleeding is usually normal and should not be too worried. Implantation bleeding may last for hours or days and is usually pink or light brown. If there is a large amount of bleeding or it lasts for a long time, you need to consult a doctor in time.
3. Detection of success and failure of implantation
After implantation, pregnant women usually conduct blood test or urine test within 10 to 14 days after embryo implantation to determine whether the implantation is successful. These tests are mainly used to detect whether the progesterone level increases to confirm whether the pregnancy is successful.
However, some IVF late implantation tests may not be accurate, because progesterone levels may fluctuate in some pregnant women. In order to confirm the success of implantation, doctors usually carry out more examinations, such as ultrasonic testing, to determine whether the embryo is successfully implanted.
4. Conclusion
After IVF implantation, both the embryo and the pregnant woman will have some physiological feelings. During implantation, the embryo needs to overcome the resistance of the inner wall of the uterus and adhere to the endometrium, so as to prepare for the smooth development. At the same time, pregnant women may experience some common symptoms, such as breast pain, nipple sensitivity and implantation bleeding. However, to determine whether the implantation was successful, pregnant women need to undergo relevant examinations.
In short, IVF implantation is a complex process, and both embryos and pregnant women will experience this process. Through timely medical monitoring and appropriate attention, the success rate of IVF implantation can be improved, bringing hope for couples to realize their reproductive dreams.
