For many couples struggling with infertility, the IVF success rate is a common question. You might be wondering whether you may conceive at the first IVF attempt.
In reality, some couples experience success in their very first attempt with IVF. However, others need more than one cycle.
Fertility success depends on several factors, like your age, embryo quality, and the health of the egg and sperm. The expertise of the fertility team also has a significant impact on the success rate.
In this blog, we have comprehensively discussed the factors that influence the success rate of IVF.
What You Should Know About IVF Success Rate
The CDC report reveals that the national fertility success of IVF treatment is 55.1% for women under 35 years of age. This number applies to the first IVF attempt upon the retrieval of eggs.
As a woman ages, this percentage gradually declines. Globally, most fertility experts state that the success rate on the first attempt lies between 30% and 40%. This success largely depends on clinical and biological factors.
| Age Group | Success Rate of First IVF Attempt |
| Under 35 years | 40% – 55.1% |
| 35 – 37 years | 35% – 40% |
| 38 – 40 years | 25% – 30% |
| 41 – 42 years | 10% – 20% |
| Over 43 years | < 10% |
As evident from the table presented above, younger women have a higher IVF success rate since they have a significantly better egg quality and quantity.
Fresh vs. Frozen Embryo Transfer Success Rates
Most fertility clinics use advanced laboratory technologies that improve the outcomes for frozen embryo transfers (FET). Compared to fresh transfers, this procedure has a slightly higher chance of success.
| Age Group | Fresh Transfer Success (Live Birth Rate) | Frozen Transfer Success (Live Birth Rate) |
| Under 35 years | 41–43% | 52–55% |
| 35–37 years | 33–36% | 44–46% |
| 38–40 years | 23–27% | 34–37% |
| 41–42 years | 13–18% | 23–26% |
| Over 42 years | 5–8% | 12–17% |
When doctors freeze the embryo, they can transfer it when the uterus is most receptive. This significantly reduces stress on the body and enhances fertility success rates.
Higher Success for Older Women With Donor Egg IVF
Older women, particularly those above 45, have a diminished ovarian reserve. Doctors recommend using donor eggs to improve the results.
Typically, fertility success with donor eggs ranges between 50% and 75% per cycle. This applies to any age, even for older women.
The reason is, younger and healthy women aged 21-34 usually donate these eggs. This significantly improves the embryo quality, and therefore, the outcome.
Key Factors That Impact IVF Success Rate
In this section, we have discussed the crucial factors that may impact your IVF success rate.
1. Age of the Woman
After the age of 32, egg quality starts declining. A sharp drop is noticed after a woman crosses 38.
2. Egg & Sperm Quality
Healthier gametes are likely to produce embryos of higher grade that are likely to be fertilized.
3. Embryo Quality
Embryos that are stronger and chromosomally normal stand a better chance of implantation.
4. Receptivity of the Uterus
When the lining of the uterus is well-prepared, it can lead to a successful implantation.
5. Lifestyle Habits
Poor lifestyle habits like smoking, consumption of alcohol, or even obesity and stress reduce the potential of success.
Emotional and Psychological Factors Influencing IVF Success Rate
Do you think that IVF is only a physical process? A lot of emotional turmoil is also involved, which eventually determines the IVF success rate.
In case you’re too anxious or stressed during the waiting period, it can leave a negative impact on the outcome. That’s the reason top fertility clinics offer 24/7 support, with reproductive health psychologists guiding patients to remain emotionally stable.
How To Increase the Success Rate On Your First IVF Attempt?
Let’s be honest – not every factor is in your control. However, the success of your first IVF attempt depends on several lifestyle and health habits. Here’s what doctors recommend.
Follow a Mediterranean-style diet
According to studies, women who follow a diet rich in olive oil, whole grains, fruits, and leafy greens stand a 65% to 68% higher IVF success rate.
Maintain a healthy BMI
Make sure to exercise regularly and maintain a healthy BMI. Balanced activity levels support better hormonal health.
Avoid unhealthy habits
Avoid smoking, alcohol, and vaping. These unhealthy lifestyle habits directly impact the quality of eggs and sperm.
Manage stress
Indulge in yoga, meditation, and counselling to maintain a healthy balance of your hormones.
The Role of Advanced Technology in Improving IVF Success Rate
Over the last decade, fertility treatments have evolved significantly. This translates to higher pregnancy and live birth rates.
Here are some of the latest technologies that help in improving your IVF success rate.
- Preimplantation genetic testing (PGT)
- Time-lapse embryo monitoring
- Vitrification (fast-freezing)
assisted hatching - ICSI (Intracytoplasmic Sperm Injection)
Conclusion
So, how likely is your first IVF attempt to be successful? As evident from medical research and reports, the IVF success rate is the highest among younger women under 35.
However, you mustn’t lose hope even if it doesn’t work the first time. With modern treatment procedures consistently improving, leading IVF clinics offer a ray of hope to couples struggling to achieve parenthood.
