2026 IVF SUCCESS BY AGE GUIDE
IVF Success Rate at Age 35, 38 and 40
Age can affect egg quality, embryo numbers and overall treatment outcomes. A useful comparison should consider age, fertility test results and how success rates are calculated.
Age 35｜About 26%
Age 38｜About 18%
Age 40｜About 10%
How Does Age Affect IVF?
As a woman gets older, ovarian reserve and egg quality generally decline. The chance of obtaining a healthy embryo may also decrease. As a result, treatment outcomes can differ significantly even when the same IVF techniques are used.
The figures below are average live birth rate references from international public data. They are not individual guarantees and should not be treated as the actual success rate of any fertility centre in Malaysia.
IVF Success Reference at Age 35, 38 and 40
Age Group 38 to 39
The average live birth rate is about 18%. Embryo number and embryo quality become increasingly important.
Age Group 40 to 42
The average live birth rate is about 10%. Ovarian reserve and overall fertility health usually require closer evaluation.
These figures refer to fresh embryo transfers using a woman’s own eggs. Success rates from different countries, clinics and reporting methods should not be compared directly.
Why Can Results Differ at the Same Age?
Ovarian Reserve AMH and antral follicle count may help estimate the number of eggs that could be retrieved.
Egg and Embryo Quality Age can affect the chance of chromosomally normal eggs, but individual results vary.
Sperm Condition Sperm count, movement and other male factors can affect fertilisation and embryo development.
Uterus and Endometrium Uterine structure, endometrial condition and gynaecological issues may affect implantation.
Laboratory and Treatment Plan Stimulation, embryo culture and transfer arrangements should be personalised.
Previous Treatment History Past egg retrieval, fertilisation and embryo transfer results can guide the next treatment plan.
Five Questions to Ask About Clinic Success Rates
| Comparison Item | What to Confirm |
|---|---|
| Definition of Success | Does the figure refer to a positive pregnancy test, clinical pregnancy or live birth? |
| Calculation Method | Is it calculated per egg retrieval, treatment cycle or embryo transfer? |
| Age Group | Does the data come from patients in a similar age range? |
| Egg Source | Were the woman’s own eggs or donor eggs used? These results should not be compared directly. |
| Treatment Type | Does the data refer to fresh embryo transfer, frozen embryo transfer or both? |
When Should You Consider a Fertility Assessment After 35?
Women aged 35 or above who have been having regular unprotected intercourse without becoming pregnant are generally advised not to wait too long before seeking an assessment. Early testing can provide a clearer picture of ovarian reserve, fallopian tubes, uterine health and sperm condition.
A fertility assessment does not automatically mean IVF is required. A fertility specialist may recommend continued natural trying, IUI or IVF depending on age, duration of trying and test results.
What to Prepare Before Your First Consultation
How Long You Have Been Trying Note how long you have been trying to conceive and whether there were previous pregnancies.
Menstrual History Include cycle regularity, significant pain or unusual bleeding.
Previous Test Results Bring AMH, ultrasound, fallopian tube assessment or semen analysis reports where available.
Previous Treatment Prepare records of any previous IUI, IVF, egg retrieval or embryo transfer.
