IVF Success Rates
“What is the IVF success rate?”
It depends on you.
There is no single IVF success rate that applies to every patient. Outcomes vary with age, ovarian reserve, egg and sperm factors, embryo development, the cause of infertility and other medical factors.

8 personal factors, one individual assessment
An overall IVF success rate is not the same as an individual’s chance of having a baby. At Sehgal IVF Centre, your fertility specialist assesses your circumstances and explains the factors that may influence your expected outcome.
What does “success rate” mean?
Six different numbers can all be called “success”
A clinic may report any of these outcomes, and they are not the same measurement. A positive pregnancy test does not necessarily result in a live birth, so always ask which outcome is reported and what the denominator is.
International reporting systems use measures such as live birth per embryo transferred and live birth per egg collection. These describe clinic-level outcomes, but cannot predict an individual patient’s chance of success.
- 01Positive pregnancy test
- 02Clinical pregnancy
- 03Ongoing pregnancy
- 04Pregnancy per embryo transferred
- 05Live birth per embryo transferred
- 06Live birth per IVF cycle started
Why the denominator matters
Same births, different percentages
A rate calculated per embryo transferred can look very different from one calculated per cycle started. Tap each option to see how.

Live birthCounted in denominatorNot counted
Illustrative example only, to show how the same outcome changes with the denominator. These are not Sehgal IVF Centre results or national statistics.
What is the average IVF success rate?
No single percentage represents every patient
For example, the latest UK national data from the HFEA reported an average IVF birth rate of 30% per embryo transferred in 2024, with substantial differences by age.
This is a UK population-level statistic and should not be read as the expected success rate for a patient treated in Delhi. What it does show clearly is that age is one of the most important factors, particularly when using a patient’s own eggs, because egg quantity and quality change with age.
Age is not the only factor. Your doctor considers your complete fertility profile rather than age alone.
What affects IVF success?
Eight factors your specialist looks at
Ovarian reserve
AMH and antral follicle count help plan treatment, but don’t by themselves predict pregnancy.
Egg quality
Important for fertilisation and embryo development; strongly linked to age, with individual variation.
Sperm quality
Concentration, movement and morphology influence fertilisation. Significant male factor may call for ICSI.
Embryo development
Embryos develop differently in the lab; the number and stage available shape treatment options.
Cause of infertility
Tubal factor, ovulation disorders, endometriosis, male factor, reduced reserve or unexplained infertility.
Uterus & endometrium
The condition of the uterus and its lining matters when planning embryo transfer.
Previous IVF history
Eggs retrieved, fertilisation, embryo development, transfers and outcomes all guide future planning.
IVF success by treatment stage
Every stage is a step, not a certainty
Not every retrieved egg will fertilise, not every fertilised egg becomes a suitable embryo, and not every transfer results in pregnancy. That’s why a pregnancy rate can give a different impression from a live-birth rate per cycle started.
- Egg retrieval
- Fertilisation
- Embryo development
- Embryo transfer
- Implantation
- Pregnancy
- Live birth

Pregnancy rate vs live birth rate
These terms are not interchangeable
When discussing IVF success, ask your clinic exactly which measurement is being used.
- Positive pregnancy test
- Pregnancy hormone is detected
- Clinical pregnancy
- Pregnancy confirmed clinically, generally through ultrasound
- Ongoing pregnancy
- Pregnancy continues beyond the early stage
- Live birth
- A baby is born alive
- Pregnancy per embryo transfer
- Pregnancy rate calculated among embryo-transfer procedures
- Live birth per embryo transfer
- Live births calculated among embryo-transfer procedures
- Live birth per cycle started
- Live births calculated from IVF cycles that were started
Your numbers, not an average
Want to understand your chances?
A personal fertility assessment looks at your age, reports, ovarian reserve, sperm factors and history, far more useful than any headline percentage.
Common assumptions
What really improves success?
Tap a card to see the answer.
Can IVF still work?
Three situations patients often ask about
With low AMH
Low AMH does not automatically mean IVF cannot work. AMH mainly helps anticipate ovarian response. The outcome also depends on:
Low AMH treatment →With male infertility
Male-factor infertility doesn’t mean IVF is impossible. Depending on the cause and severity, treatment may involve:
Male infertility →After a failed IVF cycle
A previous unsuccessful cycle doesn’t automatically mean future treatment won’t work. Your specialist may review:
IVF treatment →
Can IVF success be guaranteed?
No fertility clinic can guarantee pregnancy or live birth
IVF is an established treatment, but outcomes vary between individuals. A responsible consultation should discuss:
- Expected benefits
- Possible risks
- Treatment alternatives
- Cost
- Chances of success
- Factors specific to you
India’s ART (Regulation) Act, 2021 requires ART clinics to counsel patients about the implications and chances of success of ART procedures, and to explain their advantages, disadvantages, costs and medical risks.

Questions to ask your fertility specialist

- What factors may affect my IVF outcome?
- How does my age affect my treatment?
- What does my AMH result mean?
- How is my ovarian reserve?
- What does my semen analysis show?
- Do I need ICSI?
- How many embryos may be available for transfer?
- Should embryos be frozen?
- Is PGT appropriate for me?
- What risks should I know about?
- What outcome measure do you use when discussing IVF success?
- How is the success rate calculated?
- What is realistic for my individual situation?
The most important takeaway
There is no single IVF success rate that applies to every couple.
Instead of focusing only on a headline percentage, understand how the rate was calculated and whether it’s relevant to your situation. At Sehgal IVF Centre, your specialist reviews your history and investigations and discusses the factors that may influence your outcome.
What is a good IVF success rate?
There is no single percentage that can be called a “good” IVF success rate for every patient. Rates depend on the patient’s age, diagnosis, treatment type and the way the outcome is measured.
What is the most important factor affecting IVF success?
Age is one of the most important factors, particularly when using a patient’s own eggs. Other factors, including ovarian reserve, sperm quality, embryo development and the cause of infertility, also matter.
Does age affect IVF success?
Yes. IVF outcomes generally decline with increasing age, particularly when using a patient’s own eggs.
Can IVF guarantee a baby?
No. IVF cannot guarantee pregnancy or live birth.
Does low AMH mean IVF will fail?
No. Low AMH mainly provides information about ovarian reserve and expected ovarian response. It does not, by itself, determine whether IVF will succeed.
Does ICSI guarantee better IVF results?
No. ICSI is useful in selected cases, particularly for certain sperm-related or previous fertilisation problems. It is not a guarantee of pregnancy or live birth.
Does PGT guarantee a healthy baby?
No. PGT provides specific genetic information but cannot guarantee pregnancy, live birth or the absence of every genetic or medical condition.
Can IVF work after a failed cycle?
Yes, another IVF attempt may be appropriate for some patients. The doctor should first review the previous cycle and individual circumstances.
How can I know my personal IVF success chances?
Your fertility specialist can provide a more meaningful assessment after considering your age, fertility diagnosis, ovarian reserve, sperm factors, previous treatment and other relevant medical information.
