Multiple IVF Failures Explained By Expert Key Medical And Lifestyle Reasons Couples Should Know

Millions of people who have been facing infertility have been helped by in-vitro fertilisation IVF. Yet, IVF may not be the success of every person, even with the development of reproductive medicine. Referrals to IVF may be emotionally draining, financially consuming and very confusing to some couples. According to the experts, IVF failure cannot be often attributed to one factor but rather a complex of medical, biological, and lifestyle problems which require increased attention.The knowledge of what IVF is, why it does not work and what problems can occur can help couples make their choices and increase the likelihood of success on further cycles.

What Is IVF? A Simple Explanation

IVF, also known as an assisted reproductive technology ART, is a method of through which an egg is fertilised by sperm outside the body in a laboratory. The product is then implanted into the womb of the woman to become pregnant.

Key Steps Involved in IVF

  1. Stimulation of the ovary in order to have more than one egg.
  2. Extraction of eggs in the ovaries.
  3. Extraction of sperm and fertilisation of eggs in laboratory.
  4. Monitoring and development of embryos.
  5. Embryo implantation into the womb.
  6. Pregnancy testing and Luteal phase support.
  7. Although IVF may be said to be straightforward, every process remains complicated and has the potential to affect the result.

What Does IVF Failure Mean?

The failure of IVF typically is:

  1. Inability to get pregnant after the transfer of the embryo.
  2. Embryos implantations fail in the uterus.
  3. Hypoxia of the pregnancy or biochemical pregnancy.
  4. In cases when IVF fails twice or more, the term recurrent or repeated IVF failure is frequently used, and more in-depth research is necessary.

Experts Take On IVF Failures

Dr. Madhumitha S, MCh Reproductive Medicine and Surgery Fertility Super specialist, Rainbow Children's Hospital, Chennai Reveals,

"Repeated IVF failure affects 10% of couples due to complex causes like poor egg and sperm quality, genetic factors, advanced uterine issues, and more. Nutrition plays a major role in reproductive capability".

Another expert emphasises on repeated IVF failures due to male and female factors Dr. B. Anuradha, Senior Consultant- Gynaecologist, Prashanth Hospital, Chetpet, Chennai Reveals,

MALE FACTORS:

  1. .DNA fragmentation index high
  2. .poor morphology of sperm
  3. .Abnormal genetics or karyotyping.
  4. .Severe abnormal semen parameters.

FEMALE FACTORS:

  1. .Poor Egg morphology
  2. .Abnormal genetics or karyotyping in female
  3. .severe PCOS
  4. .severe Endometriosis
  5. .Antiphoshpolipid antibidy syndrome(deficiency of blood flow)
  6. .chronic Endometritis ( infections of uterus)
  7. .Abnormal shapes of uterus.
  8. . Fallopian tube fluid collection.
  9. .Uncontrolled diabetes
  10. .uncontrolled thyroid
  11. .immunological reasons

Frequent Medical Causes Of Repeated IVF Failures

Here are some reasons behind frequent medical causes of Repeated IVF failures

Poor Egg Quality

The quality of eggs is very important in the growth of embryos. With age, particularly above 35 years, there is a deterioration of the quality and genetic integrity of eggs in women.

Key concerns include:

  1. Chromosomal abnormalities
  2. The decrease in the oocytes fertilisation capability.
  3. Poor embryo development
  4. Although embryos may appear healthy on a microscope, their inability to implant may be due to genetic problems.

Sperm Quality Issues

The problem of male factor infertility is usually underestimated. Low sperm quality may result in the fertilisation process or genetically defective embryos.

Common sperm-related issues:

  1. Low sperm count
  2. Poor motility movement
  3. Abnormal sperm shape
  4. DNA fragmentation
  5. Further sperm testing is usually advised in case of repeated IVF failures.

Hormonal Imbalances

Hormones control ovulation, implantation and maintenance of pregnancy. IVF is susceptible to any imbalance.

Hormonal diseases associated with IVF failure:

  1. Thyroid disorders
  2. Polycystic Ovarian Syndrome (PCOS).
  3. Luteal phase deficiency
  4. Elevated prolactin levels
  5. A close observation of the hormones is necessary prior to each cycle.
  6. Immunological Factors
  7. It may also happen that the immune system can attack the embryo in order to treat it as a foreign body.

Immunological problems

  1. Increased levels of the Natural Killer cells.
  2. Autoimmune conditions
  3. Antiphospholipid antibodies
  4. These circumstances can lead to implantation failure or risk of miscarriage.

Recurrent Implantation Failure

RIF is a condition whereby good quality embryos never implant despite numerous sessions of IVF procedures.

Possible causes include:

  1. Problems of endometrial receptivity.
  2. Inadequate embryo-endometrium co-ordination.
  3. Genetic or immune factors
  4. Such tests as Endometrial Receptivity Analysis (ERA) can be used to determine the optimal time of implantation.

Ovarian Hyperstimulation Syndrome

A response to fertility medications with swollen, pain-filled ovaries.

Symptoms include:

  1. Abdominal pain and bloating
  2. Nausea and vomiting
  3. Pall of shortness of breath in the worst cases.
  4. Multiple Pregnancies
  5. Moving more than one embryo makes it more risky to have twins or triplets which may result in:
  6. Preterm birth
  7. Gestational diabetes
  8. High blood pressure
  9. Ectopic Pregnancy

What Frequent IVF Failures Can Do?

  1. Anxiety and depression
  2. Relationship stress
  3. Guilt and incompetence.
  4. The medical treatment is as significant as mental health support.

Lifestyle Factors That Decrease The IVF Success

Stress and Mental Health

Chronic stress influences the levels of the hormones and can decrease the implantation rates.

Poor Diet and Nutrition

The quality of the eggs, sperm, and embryos may be impaired by nutritional deficiencies.

Key nutrients for fertility:

  1. Folic acid
  2. Vitamin D
  3. Omega-3 fatty acid

Obese Or Underweight

Body Mass Index is a factor that is important in IVF outcomes. Obesity may decrease the quality of eggs and the reaction to hormones. Being underweight could interfere with ovulation.

Smoking, Alcohol, And Caffeine

  1. Egg and sperm DNA are damaged by smoking.
  2. Alcohol consumption leads to low fertility.
  3. Excessive consumption of caffeine can influence implantation.
  4. Professionals recommend that smoking should be stopped and alcohol intake should be reduced long before the IVF.

Women's age is still one of the most predictive factors of IVF.

Age: The Bigger Cause Of IVF Failures

  1. Under 35: Higher success rates
  2. 35 40: Gradual decline
  3. Above 40: Decrease by a large margin because of the quality of eggs.

Male age also influences sperm DNA quality which has an influence on embryo development.

Is It possible To Prevent Repeated IVF Failures?

Although IVF failure cannot be avoided in any cases, the results are possible to be improved in the personalised approach.

Some of these steps are

  1. In-depth fertility analysis.
  2. Genetic testing of embryos
  3. Advanced sperm analysis
  4. Uterine cavity assessment
  5. Lifestyle modifications
  6. Emotional counselling

Can A Patient Have Hope After Multiple IVF Failures?

Yes. Most couples successfully conceive after failing several times using:

  1. Protocol changes
  2. Better embryo selection
  3. Donor eggs or sperm when required.
  4. Better lifestyle and psychological care.
  5. Sometimes, about the correct combination, rather than abandoning, is IVF success.

Overall,Numerous failures in embryo implantation may be devastating, yet that is not the limit. The first step to more improved results would be to understand the medical, genetic, uterine and lifestyle factors. In the case of fertility science and the holistic approach, it leads to successful pregnancies for many couples who have undergone numerous setbacks.
