Struggling with infertility is often an emotionally draining experience, especially for couples in India. Beyond the support of loved ones, seeking fertility treatments and considering IVF requires a lot of strength, so experiencing failure on the first IVF try can be disheartening.

#However, it is not the end of the journey. The IVF second cycle success rate often brings hope amidst the ongoing despair. With Prime IVF and our specialists, you can turn things around. The only thing you need is to be patient and optimistic.

If you are embarking on your second cycle of undergoing IVF, let this informative guide from Prime IVF be your blueprint.

What Led to the Failure of the First IVF Cycle?

Even before you start your second cycle of IVF, the first step you need to take is to understand what went wrong the first time around.

What complications or factors led to the first cycle not working? This will be assessed at length by our fertility and IVF specialists at Prime IVF. The following are a few factors that often lead to the failure of the first IVF cycle:

• Poor egg quality
• Embryo implantation failure
• Sperm quality issues
• Uterine abnormalities
• Genetic abnormalities
• Intended mother’s age

Underlying health complications like PCOS, thyroid dysfunction, obesity, etc.

Despite the failure of the first round, what’s important to understand is that one failed IVF cycle doesn’t define future outcomes.

IVF Success Rate: First Cycle vs. Second Cycle

To better understand the effectiveness of an IVF cycle, especially on the second round, we have to compare the numbers of the first and second cycle to get a clearer picture.

A 2015 study published in JAMA found that after three IVF cycles, the cumulative live birth rate could reach up to 65% in women under 40, emphasising the importance of persistence. This is one of the primary reasons why our specialists and counsellors partner with the patients to offer guidance and assistance during the otherwise testing journey of infertility and IVF.

Furthermore, it has been found that your chances of conceiving through the second cycle of IVF is higher because of the experience you gained from the first. Also, based on the shortcomings from the first cycle, the doctors refine their approach, optimise the medications and also the treatment protocols and transfer timing.

What Are the Factors Influencing the Second IVF Cycle Success Rate?

There are numerous factors impacting the success rate of the second IVF cycle including:

• Without a doubt, age remains one of the strongest predictors of IVF success. The age of the intended mother, usually under the age of 35 assured better success rate than over 40 years.
• Your ovarian reserve, measured through AMH levels and antral follicle count, is critical. Even during the second cycle, you need a good ovarian reserve to ensure favourable outcomes.
• Embryos that are graded A and B after fertilisation usually have a better chance of implantation, ensuring a successful IVF cycle.
• If the patient has poor uterine receptivity, that will impact the IVF success rate, even during the second cycle. To ensure better success, specialists will pay close attention to the Endometrial Receptivity Array (ERA) to determine the optimal window for embryo transfer.
• The kind of lifestyle the patient follows also coins into the IVF cycle success rate. For example, if you are obese or smoke, weight management and quitting the habit will be at the forefront to ensure successful outcomes.

Beyond all of that, specialists also need to identify the cause of the failure of the first IVF cycle, whether due to fertilisation issues, embryo development, implantation failure, etc. Eradicating these components is equally important to ensure better success rates.

What Can You Expect During Second IVF Cycle?

The procedure of the second IVF cycle is not as different from the first one you underwent. In fact, the core steps in the treatment remain the same.

Here’s what you might experience differently:

1. Personalised treatment adjustments

When the first IVF cycle wasn’t a success, it leaves the fertility specialists with better understanding of the complications, which, in turn, helps make personalised treatment adjustments. Be it changing the medication dosage or modifying the stimulation protocols, the approach will be changed by the doctors to improve the IVF second cycle success rate.

2. More targeted diagnostic testing

To ensure that the second IVF cycle is a success, your fertility and IVF specialists will also conduct more thorough diagnostic testing. This might include hysteroscopy to inspect the uterus, conducting thrombophilia screening to detect any clotting disorders and conducting immune profiling to detect any unusual uterine immune responses, which might have caused the first cycle to fail.

3. Improved embryo selection

Through advanced IVF technologies like time lapse imaging, etc., the doctors will also ensure that only the best embryo is transferred into the patient’s uterus to ensure successful implantation and outcomes.

4. Psychological preparation

At Prime IVF, we understand that the second cycle is emotionally different. Some couples feel more hopeful, while others may feel the weight of the previous disappointment, which is why we have counselling sessions to help our patients navigate through the journey with hope and optimism.

How Long Should You Wait Before the Second Cycle?

Once you have received the report of the first IVF cycle not working out, how long should you wait to undergo the second cycle? This is a common question that many of our patients enquire about at Prime IVF.

On average, depending on the patient’s age and their emotional well-being, our specialists recommend waiting between 1-3 months before starting the process of the second IVF cycle. This “cooling period” allows the body to recover from the ovarian stimulations from the first cycle.

That said, the waiting period is usually dependent on factors like:

• Emotional readiness
• Medical advice
• Menstrual cycle recovery
• Lifestyle adjustments

You’d have to undergo a thorough consultation with your IVF specialist at Prime IVF following the first cycle and then discuss the best course of treatment next.

How to Improve the Second IVF Cycle Success Rates?

Now that you have all the details about the second IVF cycle and its success rates, are there any ways to optimise the success rates?

Following are a few tips you can adopt in your lifestyle:

• Chronic stress can negatively impact fertility. So, if you are stressed and anxious about the procedure, implementing stress management can help significantly.
• Both underweight and overweight impose negative impacts on IVF success rates. So, you can aim for a BMI between 18.5 and 24.9 to ensure a higher success rate.
• Your diet will also contribute to the success rate. So, consider adopting nutrient-rich diets, folid acid supplementation and antioxidants are important to enhance the success.
• Poor habits like smoking, drinking alcohol, leading a sedentary lifestyle will bring down the success rates, so make healthier lifestyle choices.

At the end of the day, if you have any concerns related to your fertility, your body, how you are feeling and how you are responding to the treatment, relay those to your doctor. Open communication helps your fertility specialists further tailor your treatment plan for optimal outcomes.
