The journey of becoming parents is filled with a whole onslaught of emotions including anticipation, hope, and sometimes, unexpected challenges. For many couples, the road to becoming parents isn’t as seamless and is otherwise burdened with fertility struggles.

However, given how far medicine has come, in-vitro fertilisation or IVF, has now gained a lot of momentum. Choosing to undergo IVF comes with significant emotional and financial investments, explaining why being informed about the process is crucial.

For couples considering IVF, a crucial question that often arises is: "What are the IVF success rates, particularly concerning age?" If you have a similar query in your mind, this detailed guide from Prime IVF Centre in Gurgaon will explore them all.

The Connection Between Age and Fertility

To truly grasp the impact of age on IVF success, it's essential to first understand its fundamental influence on natural fertility.

Research has confirmed that women are born with a finite number of eggs and with age, both the quality and the quantity of these eggs deplete. The decline accelerates significantly in the mid-30s and becomes more pronounced after the age of 40.

So, if you are considering undergoing IVF cycle, which heavily relies on the quality and availability of good eggs and sperm for a viable fertilised embryo for transplantation, age surely plays a vital factor in the equation.

There are studies that indicate that even if the fertilisation is successful with an older egg, there remains chances of development concerns, affecting the embryo’s ability to implant and grow successfully in the uterus.

IVF Success Rates by Age: A Detailed Breakdown

The concept of IVF success rates by age is not arbitrary but rooted in ongoing research and scientific studies. If you want to start your IVF journey after failing to conceive naturally, the quicker you start, the more favourable the results will be.

1. Under 30 Years

Success Rate: 50–60% per IVF cycle

With factors like:

• Excellent egg quality
• Higher ovarian reserve
• Lower risk of chromosomal abnormalities in embryos

The success rate is thus high for women who are considering undergoing IVF under the age of 30. Usually, their bodies also respond better to the ovarian stimulation, thereby producing high-quality eggs. This, in turn, ensures successful fertilisation and embryo transplantation and pregnancy maintenance.

2. 30 to 34 Years

Success Rate: 40–50% per IVF cycle

The next phase is between 30 to 34 years, which is still considered a strong window for a successful IVF procedure. During this period, you have to keep certain considerations in mind:

• Slight decline in egg quality begins
• Ovarian reserve starts to diminish

While fertility is still strong, there remains a noticeable decline both in the quality of the egg and the quantity, usually starting around the age of 32. That said, most women in this age respond well to the IVF cycle and treatment.

With Prime IVF Centre in Delhi and our fertility specialists by your side, you will get comprehensive fertility assessments in this age range to optimise IVF outcomes and avoid unnecessary delays.

3. 35 to 37 Years

Success Rate: 30–40% per IVF cycle

Tagged as the “beginning of the advanced maternal age,” 35-37 years is marked by issues like lower implantation rates, risks of miscarriages, etc.

During this period, fertility begins to drop steeply, regarding the fact that many patients might need to undergo multiple IVF cycles for a successful pregnancy. However, every body is different, so there’s no guarantee how things would pan out.

Also, the egg quality becomes more variable during this period, which can affect the fertilisation and the embryo development.

4. 38 to 40 Years

Success Rate: 20–25% per IVF cycle

As the success rate points out, this is where women start experiencing a sharp decline in both egg quality and quantity. Also, the risks of implantation failure are quite high during this phase.

By the time a woman reaches 38, the chances of IVF success per cycle drop considerably. This is primarily due to age-related factors such as decreased egg quality and fewer embryos developing to the blastocyst stage.

However, at Prime IVF, our comprehensive testing and evaluation allows you to have the best chance at embracing the beauty of pregnancy.

5. 41 to 43 Years

Success Rate: 10–15% per IVF cycle

Studies suggest that by this period, most eggs are chromosomally abnormal, which leads to issues with fertilisation. This also warrants the need to undergo multiple IVF cycles and there might be discussions about the need for donor eggs to ensure a successful pregnancy through IVF.

Discussing and undergoing IVF cycle during this age can be anxiety inducing and extremely emotionally charged for the patients, which is why we prioritise ongoing support to the patients at Prime IVF – both medically and emotionally.

6. 44 Years and Beyond

Success Rate: 5–10% with own eggs; 50–60% with donor eggs

The best approach to considering IVF during this period is with donor eggs because it enhances the chances of a successful IVF cycle by a lot. Since fertility and egg quality is quite low during this age, considering donor eggs for the IVF cycle is the most viable choice – both medically and financially.

Are There Ways to Improve IVF Success Odds by Age?

If you want to get the most out of your IVF cycle, despite the age, there are certain strategies and tips that can come in handy.

• Everyone’s fertility journey is different, which explains why the treatment plan needs to be subjective as well. This is one of the main reasons why we prioritise personalised treatment plans for each patient at Prime IVF. Our treatment protocols are based on the couple’s age, medical history, and hormone levels.
• Advanced fertility testing is mandatory to gauge the fertility of the patient before undergoing IVF. Holistic testing like semen analysis, hormone evaluation, and 3D ultrasounds provide an overall understanding to then curate the treatment plan accordingly.
• If you aren’t ready to embrace motherhood at the moment but plan to in the future, embryo freezing at an earlier age is always recommended. This preserves fertility and secures a higher success rate, even if you undergo an IVF cycle at a later age.
• Considering donor eggs or donor sperm isn’t wrong and should not be looked down on. In fact, these offer hope to many couples that are struggling with conceiving naturally or with their own eggs and sperm via IVF. Discussing donor programs with the fertility specialist can thus improve the IVF success odds too.
