What are the body signals of IVF implantation?
In vitro fertilization (IVF) is used to fertilize the IVF in the laboratory and then transplant it into the uterus for development. IVF implantation refers to the process in which the embryo successfully attaches to the endometrium. In this process, a series of body signals will occur in the female body, indicating the smooth implantation and development of the embryo. This article will elaborate from four aspects: luteal formation, abdominal discomfort, breast distention and pain, and ovulation date delay.
Luteinization
The first body signal during implantation is corpus luteum formation. During the normal menstrual cycle, the corpus luteum is formed after the release of eggs. If the fertilized eggs are not implanted, the corpus luteum will gradually shrink and decompose. However, if the fertilized egg successfully attaches to the endometrium, the corpus luteum will continue to grow and secrete progesterone. Progesterone is an important progesterone, which helps to maintain the thickness and stability of endometrium and provides a good environment for embryos. After implantation, the body of women will show the body signals after the formation of corpus luteum, such as breast pain, nipple sensitivity, etc.
In addition, when corpus luteum is formed, the temperature in the female body will rise slightly. You can observe whether corpus luteum is formed by measuring the basic body temperature. Luteinization usually occurs between 7 and 10 days after fertilization. If the basal body temperature continues to rise and menstruation does not occur, this may be a sign of successful implantation.
Abdominal discomfort
Another body signal during IVF implantation is abdominal discomfort. During implantation, the embryo forms contact with the mother through the deep connection of the endometrium. This process may cause some discomfort in early pregnancy, such as slight abdominal distension, tingling or pain. This discomfort usually lasts for hours to days.
The degree of discomfort in the lower abdomen varies from person to person. Some women may feel a stronger discomfort, while some women may hardly feel it. This discomfort is a normal physical reaction, indicating that the embryo is successfully implanted and forming contact with the uterus.
breast tenderness
After successful implantation, the level of progesterone in women will rise, especially the levels of progesterone and estrogen. The increase of these hormones will cause breast tissue congestion and pain. Breast distention and pain usually begin within a few days after fertilization and last for weeks to months.
Breast distention and pain is an obvious signal of implantation and a normal physical reaction. The degree of breast swelling and pain varies from person to person. Some women may feel slight discomfort, while some women may feel very painful. The appearance of breast distention and pain can help women determine whether they are successful in pregnancy.
Ovulation date delay
Generally, 14 days after ovulation, if there is no fertilization and implantation, menstruation will occur. After IVF implantation is successful, the cycle of women may change and the ovulation date will be postponed accordingly. At this time, women's menstrual cycle is usually prolonged, and the date of menstruation will be postponed.
The delay of ovulation date is another obvious signal of successful implantation. Women can judge whether implantation has occurred by checking the changes of menstrual cycle. The delay of ovulation date usually occurs within 14 days after implantation, which is also an ideal time point for using test paper to detect pregnancy.
summary
IVF implantation has many body signals, including luteal formation, abdominal discomfort, breast pain and delayed ovulation date. These signals reflect the successful attachment and development of the embryo to the endometrium. Women can confirm the success of implantation and further confirm their pregnancy status by observing and feeling these body signals at the early stage of pregnancy.
However, it should be noted that everyone's physical response may be different, and other physical signals may also appear. Therefore, if you suspect that you are pregnant, it is best to conduct a urine pregnancy test or consult a doctor in time to obtain an accurate diagnosis.
