Medically reviewed by Dr. Ankita Mandal, MD (OBGYN) — IVF Specialist

📌 Quick Answer

Approximate general IVF success ranges per embryo transfer: under 35: 55–70%, age 35–40: 40–50%, above 40: 20–35%. These are general figures, not this clinic's results, and not a guarantee. Your individual chances depend on age, ovarian reserve, embryo quality, uterine and sperm factors and treatment history.

IVF Success Rate by Age — Kolkata 2025

Women Under 35

55–70%

Generally the highest success bracket. Outcomes still vary between individuals.

Age 35–40

40–50%

PGT-A may be discussed in some cases; its benefits and limitations vary.

Above 40

20–35%

Donor egg IVF can raise success to 50–65% for women above 40.

Key Factors That Affect IVF Success

  • Maternal Age: The single most important determinant. Egg quality declines with age.
  • Egg Quality And Ovarian Reserve (AMH): Higher AMH means more eggs retrieved and better choices for transfer.
  • Sperm Quality: Morphology, motility, and DNA fragmentation index impact fertilization rates.
  • Uterine Health: Polyps, fibroids, or thin endometrium reduce implantation rates.
  • Embryology Lab Standards: Air quality, culture media, and incubator technology directly impact embryo viability.
  • Stimulation Protocol: Individualized protocols vs. routine ("cookie-cutter") approaches make a measurable difference.
  • Number of Eggs Retrieved: More mature eggs = better embryo selection = higher success chance.
  • Blastocyst vs Cleavage Stage Transfer: Day-5 blastocyst transfer generally yields higher implantation rates than Day-3.
  • PGT-A Testing: Screens embryos for chromosomal abnormalities; it may help some patients, but it has limitations and is not suitable for everyone.

Frequently Asked Questions

What are my chances of success at Maatritva IVF Fertility Centre?

Your chances depend on your age, ovarian reserve, embryo quality, uterine and sperm factors and treatment history. Your doctor can discuss a personal estimate after assessment.

Does IVF always work on the first try?

No. First-cycle success is not guaranteed. However, cumulative success rates improve with each subsequent cycle. Many couples need more than one cycle, and some do not conceive.

Can lifestyle changes improve IVF success?

Yes. Studies show that achieving a healthy BMI, quitting smoking, reducing alcohol, and managing stress can meaningfully improve IVF outcomes, particularly egg quality and uterine receptivity.

What is a "good" success rate for an IVF clinic?

For women under 35, a success rate of 50%+ per transfer is considered good. Be cautious of clinics claiming unusually high rates without age-stratified data — ask for broken-down statistics.
