While in vitro fertilization (IVF) technology has brought hope to many infertile families, the failure of embryo transfer can cast a shadow over expectant hearts. Nevertheless, this is a relatively common occurrence in the IVF process. What exactly causes IVF failure? And how can we scientifically improve the chances of success? Let's unravel the mysteries and explore effective ways to enhance IVF success rates.

 

Firstly, sperm quality plays a pivotal role in the success or failure of IVF. Sperm count, motility, and morphology directly determine the likelihood of fertilization. If the sperm count is too low or the motility is poor, the success rate of IVF may be affected. In such cases, opting for in vitro fertilization rather than intrauterine insemination might be a better choice to optimize sperm quality in the laboratory.

 

Secondly, egg quality is another crucial factor that cannot be ignored. A woman's egg quality gradually declines with age, especially after 35, and this decline becomes more pronounced. Therefore, for older women, the success rate of IVF may be correspondingly lower. Before undergoing IVF treatment, actively maintaining a healthy lifestyle and striving to protect egg quality are undoubtedly important steps to increase the chances of success.

 

Embryo quality is yet another core element influencing the outcome of IVF. High-quality embryos are cultivated from healthy eggs and sperm in a favorable laboratory environment. Research indicates that high-quality embryos have a greater potential for implantation and pregnancy, while lower-quality embryos are more likely to lead to failure. Furthermore, the process of embryo implantation is a complex physiological event, and a range of factors, including the health of the uterine lining and the morphology of the uterus, directly affect implantation and the progression of subsequent pregnancy. For couples with repeated implantation failures, considering preimplantation genetic testing (IVF-PGT) to screen embryos for chromosomal and genetic abnormalities and selecting healthier embryos for transfer can improve success rates.

 

Psychological factors also play a significant role in the IVF treatment process. Studies have shown that prolonged mental stress can affect the endocrine system, indirectly impacting the success rate of IVF.

Although the success rate of IVF is not 100%, choosing an experienced medical team can significantly increase the likelihood of success. Dr. Nathan Zhang and the IVF USA team have been engaged in overseas assisted reproductive consultation services for over ten years, providing services such as USA egg freezing, USA IVF, and third-party assisted reproduction to those in need. With nearly 20 years of deep cultivation in the overseas assisted reproductive field, IVF USA established a presence in the Mexican market early on, becoming the agent in China for Power Fertility Center Mexico (POWER IVF). Currently, Dr. Nathan Zhang's business has expanded beyond the United States to Mexico IVF and egg freezing, as well as Japan, Thailand, Taiwan, and Hong Kong. We look forward to embarking on the joyful journey of welcoming new life with you.
