An IVF specialist stimulates the growth of multiple eggs and then harvests these eggs for fertilization. In a controlled and precise process, the partner’s (or donor) sperm is used to fertilize viable eggs. Next, the quality of the developing embryos is evaluated. The healthiest embryo is selected, and it is transferred to the uterus. If the procedure is successful, the embryo develops into a healthy baby. Not every IVF cycle is a success, but this is an ideal process. Some patients have a chance of multiple IVF failures. Failures are expensive and take an emotional toll on the couple.
It is critical to comprehend what constitutes multiple IVF failure before talking about the cause. The term "repeated IVF failure" refers to situations where there have been three or more unsuccessful attempts to conceive after using healthy embryos. It is a term that is used to describe both situations in which a woman is unable to become pregnant and those in which a pregnancy ends in an early miscarriage.
Multiple IVF failures can have a variety of causes, and not all of them are solely the mother's fault.
Most IVF failures occur when embryos stop developing. When embryos don't implant after transfer, it is frequently because of an error that preimplantation genetic screening missed. Embryos cannot implant if they are not healthy enough to grow.
The quality of the embryo varies depending on the age of the egg. This can lead to repeated failures for women over the age of 35. In the early stages of a woman's life, all her eggs are present, however as she grows older, the quality of her eggs degrades. It is more difficult to harvest viable eggs near menopause. Women under the age of 35 have a 45% implantation rate, but women over the age of 40 typically have a 15% rate.
Around 10% of the population is affected by autoimmune diseases, and 80% of those with autoimmune disorders are women. When your immune system attacks healthy tissue, it can cause inflammation and cell death. This is known as an autoimmune disease. Hashimoto's thyroiditis, Addison's disease, celiac disease, type 1 diabetes, and lupus are a few of the more prevalent immune disorders.
The antibodies found in women with specific autoimmune diseases prevent embryo implantation and multiple IVF failures. Some people discover they have an autoimmune disease only when they start looking for reasons why they can't get pregnant.
Similar to natural conception, the main causes of IVF failure are chromosomal abnormalities in embryos. A woman's eggs start to have more chromosome abnormalities starting in her mid-30s. She will have a whopping 75% more abnormalities by the time she is in her mid-40s. As men age, chromosomal abnormalities in their sperm also rise.
Prior to implantation of the embryos in the uterus, preimplantation genetic screening or testing finds chromosomal abnormalities.
Your IVF success is impacted by factors like smoking, drinking, poor nutrition, and being significantly underweight or overweight. In fact, smoking increases the risk of miscarriage and necessitates twice as many IVF cycles for conception in women.
The quality of oocytes is likely to decline with age.
If the sperm is of poor quality, it might not be able to penetrate the egg's shell, which would result in ineffective fertilization.
Wrong Embryo Selection: If an abnormal embryo is chosen, it is likely to be rejected by the uterus. It is important to choose a normal embryo for a successful cycle.
There are high chances that an IVF cycle will fail if there are problems in the uterus, particularly the endometrial lining. The likelihood that an IVF cycle will fail also increases if the woman has fibroids, polyps, a difficult cervix, intrauterine adhesions, or an abnormally shaped uterus.
Embryo transfer is a delicate, non-surgical procedure that must be done in the proper setting and at the appropriate time. To minimise risk, it is advisable to carry out a trial transfer to make sure the embryo is positioned correctly inside the uterus.
The safe environment provided by infertility counselling allows you to express your feelings and emotions. You don't need to be concerned about offending your partner or anyone else in this situation. Instead of repressing your feelings and allowing them to worsen later, it can help you let them out. You can decide on coping mechanisms and techniques with the help of your counsellor throughout this process.
An endometrial biopsy is carried out to determine if the uterus is receptive to implantation based on gene expression investigations. It assists the specialist choose the best day to implant the embryo.
The uterus and fallopian tubes will be examined during an in-depth uterine evaluation. For a successful IVF cycle, this knowledge helps to determine the exact tubal status, reducing failure risk by nearly 50%.
Connecting with these groups of people can help you feel a little less alone as you continue to pursue your dreams of having a family. It is a good idea to research IVF support groups within your local community. In addition to providing inspiration, hearing others' stories can help you cope.
A failed IVF cycle can lead to further attempts at IVF by individuals and couples. A successful IVF cycle requires multiple cycles.
Dr Scindiya M, fertility specialist at Nova IVF fertility Madurai says that it is estimated that three IVF cycles are needed to conceive using own eggs on average. It depends on a woman's age, ovarian reserves, fallopian tubes, and lifestyle as to whether the procedure will be successful and how many cycles she will need. When it comes to IVF, women under 35 have the highest success rate. The ovarian reserve refers to the number of eggs of good quality. Fallopian tubes are also important, if there is a blockage, becoming pregnant will be difficult. Finally, lifestyle has a considerable impact on success, smoking or being overweight can affect the likelihood of success of IVF.
