Is the intima lining 14mm thick?

The key to the success of transplanting test tube embryos is the uterine wall. In order for the test tube embryos to implant and develop smoothly, there must be a natural environment suitable for their growth and development. If the endometrium is not good, it is difficult for the test tube embryos to implant and develop. The thickness of the uterine wall is very important. It is not suitable for the endometrium to be too thin or too thick. If a woman's endometrium is 18mm thick, will the transplant be successful?

We all know that the thickness of the endometrium of the uterus does not maintain a stable value. It changes with the menstrual period. The endometrium is thinner after the menstrual period and thicker before the menstrual period.

Under normal circumstances, the thickness range is between 7-15mm. Data show that if the thickness of a woman's endometrium exceeds 7.5mm, it will not affect embryo implantation. In other words, as long as the thickness is more than 7.5mm during transplantation, the success rate of embryo implantation is the same as that of a normal pregnancy, about 60%-65%.

If the uterine wall is relatively thin, with a thickness of less than or equal to 6mm, the test tube embryo is cost-effective, and the success rate can reach more than 30%. Even some 4mm thick endometrium can successfully implant the embryo. From these aspects, although the thickness of the endometrium has a great influence on embryo implantation, there are exceptions. Don't give up transplantation due to unsatisfactory thickness. Some high-quality test tube embryos can be implanted in uterine scars or bilateral fallopian tubes. In this case, an imperfect uterine wall does not mean that the embryo cannot implant.

Ultrasound examination shows that if the diameter of a high-quality egg reaches 18-22mm, the thickness of the uterine wall will generally reach 8-14mm. Because in vitro fertilization requires ovulation induction, the injection of hormones into the body will cause a surge in the level of estrogen in the female body, so the thickness of the endometrium will be thicker than normal. However, there is no definite conclusion on the limit of endometrial thickness. But if the endometrial thickness is too large, especially when it exceeds 15mm, it is recommended to perform a curettage before transplantation to see if there is any disease in the endometrium.

Medically, the thickness of the endometrium is directly proportional to the implantation of the fertilized egg. That is, the thicker the endometrium, the easier it is for the embryo to implant successfully. Therefore, for female friends with endometrial thickness of 18mm, if they want to perform embryo transplantation, endometrial curettage should be performed to check for any mutations, try to avoid factors that affect the implantation of the fertilized egg, and increase the success rate of transplantation.
