Symptoms of post-implantation chorionic villus

Does the human body feel anything when the embryo implants? In response to this question, relevant personnel said that during ovulation and after embryo implantation, a woman's body may undergo a variety of symptom changes, such as hypothermia, sudden fatigue and so on. Friends who are very interested can learn more about it.

Can the human body feel when the embryo implants?

About 7-10 days after fertilization, the sperm and egg combine to form an embryo that implants in the uterine wall and absorbs nutrients from the pregnant mother and begins to grow and develop.

Embryo implantation feeling 1: cooling

What is implantation cooling?

To understand what "implantation cooling" means, you must first understand what implantation is. Embryo implantation refers to the process in which the early embryo of viviparous mammals fuses with the endometrium of the pregnant mother, thereby establishing a structural connection between mother and child to complete the exchange of substances. After embryo implantation, the test tube embryo absorbs nutrients from the pregnant mother's blood and continues to grow and develop. Embryo implantation is a comprehensive process that requires preparation and cooperation from both mother and daughter.

The sperm and egg combine in the fallopian tubes and slowly develop (3 to 5 days). After several divisions, a morula is formed, which enters the uterus and continues to develop into an embryo (called a blastocyst). The blastocyst is surrounded by the zona pellucida and continues to grow with the help of the uterine milk that absorbs the metabolism of the uterine gland. As the blastocyst grows, the zona pellucida expands and becomes thinner, and it is torn and falls off (or melts); the test tube embryo slips out of the outer membrane. The trophoblastic somatic cells on the surface of the test tube embryo are exposed and immediately come into contact with the uterine wall. Embryo implantation is a key step in the early stages of viviparous embryo development.

Embryo implantation feeling 2: Breasts become softer

If your breasts feel tender, soft, and swollen, you may be pregnant. This type of symptom may appear in the first few days after pregnancy. If you've been suddenly unable to recognize your breasts (hello, Pamela Decker Lee!), you might be pregnant. Don't worry! After your body absorbs a large amount of testosterone, this pain will disappear and your breasts will no longer feel uncomfortable.

Bed feeling three: feeling tired

Are you, who have always been full of energy, suddenly feeling physically and mentally exhausted? A lot of metabolism of luteinizing hormone (a male hormone) can make you feel exhausted. Almost all pregnant women suffer from this symptom, and you can observe other symptoms to confirm your suspicions.

The following are the reasons why embryo implantation fails

1. The combination of sperm and egg itself has defects: Because the combination of sperm and egg itself has defects.

2. Uterine factors: Failure of embryo implantation may be due to uterine hypoplasia, cervical fibroids, uterine intrauterine polyps, intrauterine adhesions, uterine wall tuberculosis, etc.

3. Immune factors: Scientific research on immune factors in recent years has found that there are two immune conditions that affect pregnancy.

Immunity: Sperm, seminal plasma or sperm-egg combination are antigenic substances. After being absorbed by the vaginal and uterine epithelial cells, antibodies are produced through immune response, which prevents sperm and egg cells from fusing or sperm-egg combination from implanting.

Autoimmunity: Infertile women have autoantibodies in the zona pellucida of their blood cells, which react with the zona pellucida to prevent the male sperm from penetrating the egg cell, thus preventing fertilization.
