Can You Do IVF After 40?
One of the most common questions I hear in my clinic is: “Doctor, I’m 40 — is it too late for me?” My answer is always the same — it is not too late, but it does require a more careful and personalised approach.
Yes, IVF is absolutely possible after the age of 40. Many women in their early-to-mid 40s have successfully conceived with IVF treatment. However, I always explain to my patients that the process becomes more medically complex as we age, and setting realistic expectations is essential for emotional and physical wellbeing.
The key factor is not your age alone — it is the quality and quantity of your eggs (what doctors call your ovarian reserve). Some women at 42 have a better ovarian reserve than others at 38. This is why a detailed fertility evaluation before starting IVF is so important.
What We Check Before Starting IVF
- AMH (Anti-Müllerian Hormone) test — measures egg reserve
- Antral Follicle Count (AFC) via ultrasound
- Day 2 or Day 3 FSH and estradiol hormone levels
- Uterine lining assessment
- Partner semen analysis
- Overall health screening including blood pressure, thyroid and diabetes
Are the Risks Higher After 40?
I always believe in honest conversations with my patients. Yes, there are higher risks associated with pregnancy after 40 — both related to the IVF process itself and to carrying a pregnancy at this age. But these risks can be managed with proper medical care and monitoring.
Increased Medical Risks After 40
Chromosomal abnormalities
— in embryos — the most significant concern. Older eggs have a higher risk of producing embryos with conditions like Down syndrome.
Higher miscarriage rate
— up to 40–50% in natural cycles for women over 40, though IVF with genetic testing (PGT-A) can lower this significantly
Gestational diabetes
— risk increases with maternal age.
Preeclampsia (high blood pressure in pregnancy)
— more common after 40.
Placenta previa and low-lying placenta
— slightly higher incidence.
Placenta previa and low-lying placenta
— slightly higher incidence.
Caesarean delivery
— more likely in older mothers due to labour complications.
Ovarian Hyperstimulation Syndrome (OHSS)
— a risk with any IVF cycle, though less common with reduced reserve.
Lower response to stimulation medications
— fewer eggs retrieved per cycle.
The good news is that with modern fertility technology — especially Preimplantation Genetic Testing for Aneuploidies (PGT-A) — we can screen embryos for chromosomal abnormalities before transfer. This dramatically reduces the risk of miscarriage and increases the chance of a healthy pregnancy.

💡 Why Donor Eggs Change Everything
When a woman over 40 uses donor eggs from a younger woman (typically aged 21–30), the success rates jump dramatically. The uterus of a woman in her 40s is usually healthy enough to carry a pregnancy — it is mainly the egg quality that declines with age. Donor egg IVF bypasses this barrier and gives a much higher chance of success.
My Advice for Women Over 40 Considering IVF
Having guided hundreds of women through this journey, I want to share some honest, compassionate advice.
Do not delay your consultation.
Every month matters after 40. Even waiting 3–6 months can reduce your options. Book a fertility evaluation now, even if you are still deciding.
Get your AMH tested.
This simple blood test gives us a clear picture of your ovarian reserve and helps us plan the right protocol for you
Consider freezing embryos early
if you are still in your late 30s or early 40s and planning for the future.
Discuss donor eggs openly.
It is not giving up — it is choosing a scientifically sound path to parenthood. Many of my patients say using donor eggs was the best decision of their lives.
Be open to genetic testing of embryos (PGT-A).
It significantly improves your chances of a healthy baby and reduces miscarriage risk.
Focus on lifestyle.
Maintaining a healthy weight, reducing stress, avoiding smoking, and taking folic acid and vitamin D can improve outcomes.
Seek emotional support.
IVF is emotionally demanding at any age. Do not go through it alone — speak to a counsellor or join a support group.
