IVF can fail despite having good embryos due to factors like implantation issues, uterine abnormalities, genetic abnormalities, immune system disorders, poor endometrial receptivity, or unexplained infertility. A thorough evaluation can help identify and address potential causes for a successful outcome. For couples experiencing repeated IVF failures, further investigations such as genetic testing, immunological assessments, and endometrial receptivity analysis may help improve future success rates. A personalized approach, guided by an experienced fertility specialist, is key to overcoming these challenges.
