How many times are IVF babies likely to fail?
Test tube baby is a kind of assisted reproductive technology, which is widely used in infertile couples. Although the success rate of IVF has gradually increased, there is still the possibility of failure. This article will elaborate on the possibility of several failures of IVF from four aspects: embryo quality, uterine environment, sperm quality and hormone level.
Embryo quality
Embryo quality is one of the important factors for the success of IVF. During in vitro culture, embryos must have normal cell division and development ability. However, not every embryo can achieve the desired quality. Some embryos may have chromosome abnormalities, insufficient cell number or delayed development. These factors will affect the ability of embryo implantation and implantation, which will increase the possibility of IVF failure.
In addition, embryo selection before embryo implantation is also crucial. Embryos implanted too early or too late may affect implantation and embryo development, leading to IVF failure. Therefore, doctors need to comprehensively consider the embryo quality and appropriate implantation timing to improve the success rate of IVF.
Uterine environment
The uterine environment is also one of the important factors for the success of IVF. The thickness, texture and blood supply of endometrium will affect the implantation and implantation of embryos. If the endometrium is too thin, the texture is abnormal or the blood supply is insufficient, the embryo may not be able to implant normally, leading to the failure of IVF.
In addition, gynecological diseases such as endometriosis and hysteromyoma also affect the success rate of IVF. These diseases will change the structure and function of the uterus and hinder the implantation and development of embryos. Therefore, before IVF, women need to undergo a comprehensive gynecological examination to ensure a suitable uterine environment.
Sperm quality
Sperm quality is one of the important factors that affect the success of IVF. The number, vitality and morphology of sperm will affect the fertilization process and embryo development. If the quality of male sperm is not ideal, the fertilization ability will decline, thus increasing the risk of IVF failure.
Sperm quality is affected by many factors, including age, living habits, environmental pollution, etc. Some men may have hereditary sperm abnormalities, abnormal sperm concentration or limited mobility. For couples with large differences in sperm quality, it may be necessary to adopt appropriate auxiliary technologies, such as sperm donation or single sperm injection, to improve the possibility of IVF success.
Hormone levels
Hormone level is also one of the important factors affecting the success of IVF. Appropriate hormone levels can promote ovarian ovulation and endometrial preparation, and improve the chance of pregnancy and pregnancy. However, too high or too low hormone levels will affect the success rate of IVF.
Women need multiple hormone treatments and monitoring to ensure that hormone levels are within the appropriate range. If the hormone level is unstable or fluctuates excessively, it may lead to abnormal ovarian function or endometrial dysplasia, thus increasing the risk of IVF failure.
Summary
In conclusion, IVF is more likely to fail several times, mainly due to embryo quality, uterine environment, sperm quality and hormone level. The selection of embryo quality and implantation time, as well as the suitability of female uterine environment, are important factors affecting the success of IVF. In addition, men's sperm quality and women's hormone levels also need attention. Through comprehensive consideration of these factors, doctors can develop personalized treatment plans for different couples to improve the possibility of IVF success.
