Who Should Consider IVF? Is It Right for You?

Are you wondering if In Vitro Fertilisation (IVF) is the right path for you? IVF is a fertility treatment that involves fertilising an egg with sperm outside the body, in a laboratory, and then transferring the resulting embryo into the uterus. This blog post, by Dr. Rukkayal Fathima in Chennai, will help you understand the specific conditions and circumstances that make IVF a viable and beneficial treatment option.

What Is IVF and How Does It Work

IVF is a complex series of procedures used to help with fertility or prevent genetic problems and assist with the conception of a child. During IVF, mature eggs are collected (retrieved) from your ovaries and fertilised by sperm in a lab. Then the fertilised egg (embryo) or eggs are transferred to your uterus. One full cycle of IVF takes about three weeks. Sometimes these steps are split into different parts, and the process can take longer.

As a fertility specialist practising across multiple locations in Chennai, I've seen firsthand how IVF can transform lives. In my clinical experience, IVF offers a ray of hope for many couples struggling with infertility. The treatment involves several key steps:

1. Ovarian Stimulation: Medications are used to stimulate the ovaries to produce multiple eggs. Follicular monitoring using ultrasound helps track the growth of the eggs.
2. Egg Retrieval: A minor surgical procedure is performed to retrieve the eggs from the ovaries.
3. Fertilisation: The eggs are fertilised with sperm in a laboratory setting. Intracytoplasmic sperm injection (ICSI) may be used if there are male factor infertility issues.
4. Embryo Culture: The fertilised eggs (embryos) are monitored and cultured in the lab for several days.
5. Embryo Transfer: One or more embryos are transferred into the uterus.
6. Pregnancy Test: A blood test is performed about two weeks after the embryo transfer to determine if pregnancy has occurred.

IVF can be performed using your own eggs and your partner's sperm. Or IVF may involve eggs, sperm or embryos from a known or anonymous donor. In some cases, a gestational carrier — someone who has an embryo implanted in their uterus — might be used.

Who Needs IVF

IVF is not a one-size-fits-all solution, but it can be a game-changer for individuals and couples facing specific fertility challenges. Here's a breakdown of common IVF indications:

• Blocked or Damaged Fallopian Tubes: This is one of the most common reasons for considering IVF. Blocked tubes prevent the egg and sperm from meeting, making natural conception impossible.
• Endometriosis: This condition can affect the function of the ovaries, uterus, and fallopian tubes, making it difficult to conceive. IVF can bypass these issues.
• Ovulation Disorders: If you have irregular or absent ovulation, IVF can help by controlling the timing of egg release and fertilisation.
• Male Factor Infertility: Low sperm count, poor sperm motility (movement), or abnormal sperm morphology (shape) can hinder fertilisation. IVF, often with ICSI, can overcome these challenges. In my practice, I've seen many couples benefit from ICSI, where a single sperm is injected directly into the egg.
• Unexplained Infertility: Sometimes, despite thorough testing, the cause of infertility remains unclear. In such cases, IVF may be recommended after other treatments have failed.
• Genetic Disorders: If you or your partner are carriers of a genetic disorder, IVF with preimplantation genetic testing (PGT) can help screen embryos for the condition before transfer.
• Age-Related Infertility: As women age, their fertility declines, especially after 35. IVF can increase the chances of pregnancy in older women, although success rates are lower.
• Previous Failed IUI Cycles: If you've undergone several cycles of intrauterine insemination (IUI) without success, IVF may be the next logical step.
• Fertility Preservation: Women who need to undergo medical treatments like chemotherapy or radiation, which can impact fertility, may choose to freeze their eggs for future IVF.

IVF is also an option for single women and same-sex couples who want to have a child using donor sperm or eggs. For instance, donor egg IVF can be highly effective for women with diminished ovarian reserve or advanced age.

IVF Step-by-Step Process

Understanding the IVF process can help alleviate anxiety and prepare you for each stage. Here's a detailed overview:

1. Initial Consultation and Evaluation: This involves a thorough review of your medical history, physical examination, and fertility testing to assess your suitability for IVF. These tests may include hormone level assessments, semen analysis for the male partner, and an ultrasound to evaluate the uterus and ovaries.
2. Ovarian Stimulation: You'll receive fertility medications, usually injectable hormones, to stimulate your ovaries to produce multiple eggs. The goal is to retrieve as many healthy eggs as possible, as not all eggs will fertilise or develop into viable embryos. This phase typically lasts 8-14 days.
3. Follicular Monitoring: Regular monitoring with blood tests and ultrasounds is crucial during ovarian stimulation to track the development of follicles (fluid-filled sacs containing the eggs). This helps the fertility specialist adjust medication dosages and determine the optimal time for egg retrieval.
4. Trigger Shot: Once the follicles reach the desired size, a "trigger shot" of human chorionic gonadotropin (hCG) is administered to mature the eggs and prepare them for retrieval.
5. Egg Retrieval: About 34-36 hours after the trigger shot, the eggs are retrieved from the ovaries using a transvaginal ultrasound-guided needle aspiration. This is usually performed under sedation or local anaesthesia.
6. Fertilisation: The retrieved eggs are fertilised with sperm in the laboratory. This can be done by mixing the eggs with sperm in a petri dish (conventional insemination) or by injecting a single sperm directly into each egg (ICSI).
7. Embryo Culture: The fertilised eggs (embryos) are cultured in the lab for several days, typically 3-5 days, to allow them to develop. Embryologists monitor the embryos' development and select the most viable ones for transfer.
8. Embryo Transfer: One or more embryos are transferred into the uterus through a thin catheter inserted through the cervix. The number of embryos transferred depends on factors like age, embryo quality, and previous IVF attempts.
9. Luteal Phase Support: After embryo transfer, you'll receive hormonal support, usually progesterone, to help prepare the uterine lining for implantation.
10. Pregnancy Test: A blood test is performed about two weeks after the embryo transfer to determine if pregnancy has occurred.

The entire IVF cycle, from initial consultation to pregnancy test, typically takes about 4-6 weeks.

Success Rates of IVF

IVF success rates depend on several factors, including:

• Age: Younger women generally have higher success rates.
• Ovarian Reserve: The quantity and quality of eggs.
• Underlying Infertility Issues: Some conditions, like severe endometriosis or male factor infertility, can lower success rates.
• Embryo Quality: The quality of the embryos transferred.
• Clinic Expertise: The experience and expertise of the fertility clinic and its staff.

Here's a general overview of IVF success rates based on age, using data adapted from multiple fertility clinics and research studies:

It's essential to have realistic expectations and understand that IVF success is not guaranteed. As a fertility specialist, I believe in providing honest and transparent information to my patients. At our clinic, we maintain a realistic IVF success rate of over 65%, focusing on patient-specific factors and individualised treatment plans.

IVF Cost in Chennai

The cost of IVF in Chennai can vary depending on several factors, including the clinic, the medications used, and any additional procedures required. Generally, a single IVF cycle in Chennai can range from ₹1,50,000 to ₹3,00,000. This cost typically includes:

• Consultation Fees: Initial consultation and evaluation.
• Fertility Medications: To stimulate egg production.
• Monitoring: Blood tests and ultrasounds during ovarian stimulation.
• Egg Retrieval: The procedure to collect the eggs.
• Fertilisation: The process of fertilising the eggs with sperm.
• Embryo Culture: The cost of culturing the embryos in the lab.
• Embryo Transfer: The procedure to transfer the embryos into the uterus.

Additional costs may include:

• ICSI (Intracytoplasmic Sperm Injection): If needed for male factor infertility.
• PGT (Preimplantation Genetic Testing): To screen embryos for genetic disorders.
• Embryo Freezing: If there are extra embryos to preserve for future use.
• Medications for Luteal Phase Support: After embryo transfer.

It's important to discuss the cost of IVF with your fertility clinic and understand what is included in the price. Some clinics offer package deals or financing options to help make IVF more affordable. While cost is a significant consideration, remember that the expertise of the fertility specialist and the quality of the clinic are also crucial factors in determining IVF success.

Risks and Side Effects

Like any medical procedure, IVF carries some risks and potential side effects. It's important to be aware of these before starting treatment.

• Ovarian Hyperstimulation Syndrome (OHSS): This is a condition that can occur when the ovaries become swollen and painful due to fertility medications. In severe cases, it can lead to fluid accumulation in the abdomen, nausea, vomiting, and shortness of breath. Careful monitoring during ovarian stimulation can help prevent OHSS.
• Multiple Pregnancy: IVF increases the risk of multiple pregnancies (twins, triplets, or more) because more than one embryo may be transferred into the uterus. Multiple pregnancies carry a higher risk of complications, such as premature birth, low birth weight, and gestational diabetes.
• Ectopic Pregnancy: In rare cases, the embryo may implant outside the uterus, usually in the fallopian tube (ectopic pregnancy). This is a life-threatening condition that requires immediate medical attention.
• Miscarriage: The risk of miscarriage is slightly higher in IVF pregnancies compared to natural pregnancies, especially in older women.
• Medication Side Effects: Fertility medications can cause side effects such as bloating, mood swings, headaches, and breast tenderness.
• Egg Retrieval Complications: Egg retrieval is a minor surgical procedure, but it carries a small risk of complications such as bleeding, infection, or damage to nearby organs.

As a fertility specialist, I take every precaution to minimise these risks and ensure the safety of my patients. We carefully monitor each patient throughout the IVF process and adjust treatment protocols as needed.

What to Expect After IVF

After the embryo transfer, it's important to take care of yourself and follow your fertility specialist's instructions. Here are some general guidelines:

• Rest: Get plenty of rest and avoid strenuous activities for the first few days after the transfer.
• Medications: Continue taking any prescribed medications, such as progesterone, to support the uterine lining.
• Diet: Eat a healthy, balanced diet and stay hydrated.
• Avoid Smoking and Alcohol: Refrain from smoking and drinking alcohol, as these can negatively impact pregnancy.
• Stress Management: Practice relaxation techniques to manage stress, as high stress levels can affect IVF success.
• Follow-Up Appointments: Attend all scheduled follow-up appointments with your fertility specialist.

It's normal to experience some anxiety and uncertainty during the two-week wait before the pregnancy test. Try to stay positive and focus on self-care. If you experience any unusual symptoms, such as severe abdominal pain or heavy bleeding, contact your fertility specialist immediately.

When to Seek Professional Help

If you've been trying to conceive for a year without success (or six months if you're over 35), it's time to seek professional help from a fertility specialist. Other reasons to consider seeking help include:

• Irregular or absent periods
• Known fertility issues, such as blocked fallopian tubes or male factor infertility
• History of recurrent miscarriages
• Family history of genetic disorders
• If you are considering fertility preservation options

A fertility specialist can evaluate your individual situation, perform the necessary tests, and recommend the most appropriate treatment options. For personalised guidance, book a consultation with Dr. Rukkayal Fathima.
