Recurrent-IVF-Failures

People fail to understand that pregnancy is a very complex process. Even after obtaining healthy eggs and sperms, combining them successfully in a laboratory and putting an apparent healthily dividing embryo into the uterus, there is much that can go wrong.

Only about 40%-50% of the people who try to get a baby do so after the very first chance. There are a few specific factors that have been identified to cause IVF failure.

  • Age-related issues: Advanced maternal age is a significant factor influencing IVF success rates. As women age, their ovarian reserve diminishes, resulting in fewer and lower-quality eggs, which can affect embryo quality and implantation.
  • Ovarian response: In some cases, the ovaries may not respond adequately to the fertility drugs used to stimulate egg production. This can lead to a reduced number of retrieved eggs, limiting the chances of creating viable embryos.
  • Egg quality: Even with a good number of eggs retrieved, some may have abnormal chromosomal structures, making them less likely to develop into healthy embryos. Poor egg quality can lead to failed fertilization or early pregnancy loss
  • Sperm quality: Male factor infertility can also play a role in IVF failure. Low sperm count, poor motility, or abnormal morphology can impact fertilization and embryo development.
  • Embryo quality: Even when fertilization occurs, not all embryos are viable. Some embryos may have genetic abnormalities or fail to develop properly, resulting in unsuccessful implantation or early miscarriage.
  • Implantation issues: For successful pregnancy, embryos must implant firmly into the uterine lining. However, certain factors like thin endometrial lining, uterine abnormalities, or immune system response can hinder implantation.
  • Endometrial receptivity: The timing of embryo transfer is critical, and an out-of-sync endometrial receptivity window can affect implantation success. Proper synchronization between the embryo and the uterine lining is essential. Else can cause failure of implantation in IVF
    Polycystic ovary syndrome (PCOS): Women with PCOS may experience irregular ovulation, hormonal imbalances, and difficulties in embryo implantation, reducing IVF success rates
  • Uterine abnormalities: Structural abnormalities in the uterus, such as fibroids or adhesions, can interfere with embryo implantation and pregnancy development.
  • Lifestyle factors: Smoking, excessive alcohol consumption, and obesity can negatively impact IVF outcomes, as they may affect egg quality and hormone levels. Also certain food products can also cause negative impact on the implantation leading to early miscarriage.
  • Medication-related issues: Incorrect dosage or individual responses to fertility medications can result in suboptimal egg development or ovulation.
  • Failed fertilization: In some cases, despite sperm and egg being viable, fertilization may not occur naturally or with conventional IVF methods. In such situations, intracytoplasmic sperm injection (ICSI) may be recommended.
  • Genetic issues: Certain genetic conditions can lead to recurrent implantation failure or early miscarriages.
  • Stress and emotional factors: Stress and anxiety can affect hormone levels, potentially impacting the IVF process. Emotional well-being and psychological support are essential during fertility treatments.
  • Unexplained infertility: In some cases, the exact cause of IVF failure may remain unclear, leading to the diagnosis of unexplained infertility. This can be due to immunological rejection of pregnancy.
