Reasons why the fertilized egg cannot implant

If a woman's fertilized egg cannot implant, it is a very serious matter, which will cause her to experience infertility symptoms. We need timely treatment. The main reasons why the fertilized egg cannot implant are excessive mental stress and imperfect ovarian corpus luteum function. This is mainly because the reproductive endocrine system is affected, leading to endometrial abnormalities.

Reasons for embryo failure to implant

1. Excessive mental stress affects the implantation of fertilized eggs

The female reproductive endocrine system is influenced and regulated by the cerebral cortex. Long-term mental stress and anxiety may cause ovulation to be advanced, delayed, or even absent, which naturally greatly reduces the chance of conception.

2. Imperfect ovarian corpus luteum function affects fertilized egg implantation

Poor ovarian corpus luteum function, insufficient progesterone secretion, and abnormal endometrium affect the implantation of the fertilized egg. Such women need to undergo six hormone tests.

3. Uterine factors affect the implantation of fertilized eggs

Uterine hypoplasia, submucous uterine fibroids, endometrial polyps, intrauterine adhesions, endometrial tuberculosis, etc. are all common factors that affect the implantation of the fertilized egg.

4. Immune factors affect the implantation of fertilized eggs

Inflammation and damage to the female reproductive tract can also produce antibodies in female serum and cervical mucus. At this time, the macrophages in the female reproductive tract, especially the uterus, will cause an immune response and perform "self-defense", which can make the sperm that has penetrated the cervix inactive, agglutinate or die.

5. Alloimmunization affects the implantation of fertilized eggs

Sperm, seminal plasma or fertilized egg are antigenic substances. After being absorbed by the vaginal and uterine epithelium, they produce antibody substances through immune reaction, which prevents the sperm and egg from combining or the fertilized egg from implanting.

6. Autoimmunity affects the implantation of fertilized eggs

There are zona pellucida autoantibodies in the serum of infertile women. After reacting with the zona pellucida, they can prevent sperm from penetrating the egg, thus affecting the implantation of the fertilized egg.

Although there are many reasons for the failure of the embryo to implant, women must maintain an optimistic attitude during the pregnancy preparation period. Do not doubt your body directly after failing to conceive. The important thing is to have a reasonable diet and schedule during the pregnancy preparation period. Pregnancy also depends on fate. Do not always think that it is because of your physical problem.
