Failure of fertilized egg implantation

Conception is a very wonderful thing. It not only requires healthy eggs and sperm, but also after the sperm and egg combine, only if they successfully implant in the uterus can the fertilized egg continue to develop into a fetus. If the fertilized egg fails to implant, it means that the conception has failed. However, after the fertilized egg fails to implant, the early pregnancy test paper can still test weakly positive. What's going on?

In fact, the implantation of the fertilized egg itself is a delicate matter. Some women may experience some bleeding when the fertilized egg implants, and some may be accompanied by lower abdominal pain, which feels like menstruation is about to come. In fact, it is caused by the implantation of the fertilized egg.

The main reasons for the failure of fertilized egg implantation are:

1. Immune factors. Immune factors are the main reason why the fertilized egg fails to implant. There are two immune factors in women's bodies: alloimmunity and autoimmunity. Alloimmunity causes sperm, seminal plasma, and fertilized eggs to be absorbed by the vagina and uterine epithelium, and then produce antibodies through immune response; or the woman's own immunity prevents fertilization, which can directly lead to the failure of the fertilized egg to implant.

2. Insufficient progesterone secretion. Due to insufficient progesterone secretion in women, the corpus luteum of the ovary is not functioning properly, resulting in abnormalities in the endometrium of women, which may also cause the fertilized egg to fail to implant.

3. Uterine hypoplasia. Uterine hypoplasia in women can cause submucosal fibroids, endometrial polyps, intrauterine adhesions, endometrial tuberculosis, etc., leading to the failure of the fertilized egg to implant.

4. Too much pressure. The psychological pressure of infertility on women causes excessive mental stress, which can lead to excessive stress over a long period of time and may also cause the fertilized egg to not implant, endangering their normal fertility.

The above is a detailed analysis of the reasons for the failure of fertilized egg implantation. If you want to conceive successfully, you must first check your body during the pregnancy preparation stage to see if there are any conditions that are not conducive to conception. Also, you must pay attention to keeping your mood relaxed during the pregnancy preparation stage. The more nervous you are, the less likely it is to get pregnant successfully. I hope you can pay attention.
