How Is IVF Success Rate Measured?
IVF success rates can be reported in different ways, which is why it is important to ask clinics exactly how they define their numbers. The key metrics used are:
- Clinical Pregnancy Rate: Confirmed pregnancy by ultrasound (fetal heartbeat) per cycle started. At Pratham IVF, our reported rate of 73% is based on this metric — the most meaningful measure of real pregnancy.
- Biochemical Pregnancy Rate: A positive blood test (beta-hCG) that includes very early losses. This figure is always higher than the clinical rate.
- Live Birth Rate: Babies born per cycle — the most important long-term metric. This is discussed individually at your consultation based on your age and diagnosis.
- Cumulative Success Rate: The probability of success over 2–3 cycles including frozen embryo transfers (FET). This figure is significantly higher than a single-cycle rate.
At Pratham IVF, when we say 73%, we mean confirmed clinical pregnancies — not just positive blood tests. We believe in complete transparency with our patients.
IVF Success Rate by Age — What to Expect
Age is the single biggest factor affecting IVF success. Egg quality and ovarian reserve naturally decline with age, which impacts fertilization and implantation rates. Here is a general guide:
- Under 30: 55–70% per cycle — best egg quality and highest success rates.
- 30 to 34: 45–65% per cycle — still good ovarian reserve.
- 35 to 37: 35–50% per cycle — slight decline begins, blastocyst culture strongly recommended.
- 38 to 40: 20–35% per cycle — egg quality declining, individualised protocols critical.
- 41 to 42: 10–20% per cycle — donor eggs may be recommended to improve outcomes.
- 43 and above: 5–10% per cycle — donor egg IVF strongly recommended for better success chances.
These are general population averages. Individual results vary based on diagnosis, embryo quality, and clinic protocols. Our overall 73% rate reflects results across our full patient population at Pratham IVF Center.
What Drives Pratham IVF's High Success Rate?
Our 73% success rate is built on five key pillars that set us apart from other IVF centers in Ahmedabad:
1. Individualised Stimulation Protocols
We do not use a single standard protocol for every patient. Based on your hormonal profile (AMH, FSH, AFC), age, and prior treatment history, we design a personalised ovarian stimulation plan that maximises the number and quality of eggs retrieved while minimising risk.
2. Advanced Embryology Laboratory
Our state-of-the-art in-house embryology lab maintains precise temperature, pH, and gas concentration — all critical for healthy embryo development. The lab follows international quality standards under the direct supervision of Dr. Dharmesh Kapadia, a Senior Embryologist trained in Australia.
3. Blastocyst Culture
We extend embryo culture to Day 5 (blastocyst stage) wherever possible. Blastocysts have significantly higher implantation rates compared to Day 3 embryos because only the strongest embryos survive to this stage — ensuring we transfer only the best. Learn more about our blastocyst culture program.
4. OHSS-Free Clinic Protocol
Ovarian Hyperstimulation Syndrome (OHSS) can force cycle cancellation and significantly reduce success rates. Our optimised stimulation and freeze-all strategies have made Pratham IVF an OHSS-Free Clinic — protecting patients while fully preserving embryo quality.
5. Experienced Multi-Specialist Team
Our unique advantage is having an in-house MCh Urologist (Dr. Kalpesh Kapadia, Gold Medalist) alongside our IVF team. For couples with male infertility, having a urologist on-site means faster diagnosis, better sperm retrieval (TESA/PESA), and higher fertilization rates — directly improving the overall IVF success rate.
Factors That Affect IVF Success Rate
Understanding what influences your success rate helps you prepare better for treatment. Here are the key factors:
Factors That Improve Success
- Younger age (under 35)
- Good ovarian reserve (AMH > 1.0 ng/mL)
- Normal uterine cavity
- Good sperm parameters
- Healthy BMI (18.5 – 25)
- Non-smoker, low alcohol intake
- Experienced embryology team
- Blastocyst culture
- Personalised stimulation protocol
Factors That Reduce Success
- Advanced maternal age (40+)
- Low ovarian reserve (AMH < 0.5 ng/mL)
- Severe male factor infertility
- Uterine fibroids, polyps, or adhesions
- Endometriosis (severe)
- Obesity or being underweight
- Smoking or chronic stress
- Repeated implantation failure
- Genetic embryo abnormalities
How to Improve Your IVF Success Chances
Before and during treatment, the following steps can significantly improve your success rate:
- Start early — The earlier you seek treatment, the better your egg reserve and quality.
- Get a complete workup — Including infertility workup, semen analysis, and hormonal tests.
- Maintain a healthy weight — BMI between 18.5 and 25 improves ovarian response to stimulation.
- Take prescribed supplements — Folic acid, CoQ10, and Vitamin D as recommended by your doctor.
- Avoid smoking and alcohol — Both significantly reduce egg and sperm quality.
- Manage stress — Mild exercise, meditation, and good sleep support hormone balance.
- Choose the right clinic — Experience, lab quality, and protocol individualisation matter enormously. If you are considering IVF, consult our specialists today.
Frequently Asked Questions — IVF Success Rate
What is the IVF success rate for the first attempt?
For the first IVF attempt, success rates typically range from 40–60% depending on age and diagnosis. At Pratham IVF, our 73% rate reflects results across our full patient population. First-cycle success is highest for younger patients with good egg reserve.
Is a 73% IVF success rate good?
Yes — 73% per cycle is excellent. The global average IVF success rate is approximately 40–50%. India's national average is 40–60%. Achieving 73% consistently over 18+ years and 12,500+ cycles reflects the quality of our embryology team, lab protocols, and personalised approach.
Does frozen embryo transfer (FET) have a good success rate?
Yes. Frozen embryo transfers at Pratham IVF have comparable success rates to fresh transfers, and in some cases better — because the uterus has more time to recover, and we can time the transfer to the optimal endometrial window.
Can I improve my IVF success rate after one failed cycle?
Absolutely. After a failed cycle, our team conducts a detailed review — examining stimulation response, fertilization, embryo quality, and implantation factors. We then adjust the protocol for the next cycle. Many patients who failed elsewhere have achieved pregnancy at Pratham IVF.
What is the IVF success rate with donor eggs in Ahmedabad?
Donor egg IVF typically achieves higher success rates (60–75%) because donor eggs come from younger women with optimal egg quality. This is a good option for women over 40 or those with very low egg reserve. Contact us for a confidential consultation to discuss this option.
