When should you seek help?
Women over 40 are often advised to see a fertility specialist when they start trying or within a few months. Early evaluation gives the most options.
What should be checked before pregnancy?

What treatment options may be considered?
Natural conception with monitoring
Some women conceive naturally, especially in the early forties with good egg reserve.
IUI
May be offered in selected women, though IVF is often discussed sooner at this age.
IVF
IVF allows embryos to be created and assessed. Outcomes depend strongly on age and egg reserve.
Genetic testing of embryos (PGT-A)
May be discussed to select embryos with the expected number of chromosomes. It has benefits and limitations that your specialist will explain.
Donor eggs
For some women, using eggs from a younger donor offers a higher chance of pregnancy. This is a personal decision, with legal and counselling support.
Antenatal care after 40
Expect closer monitoring, including early scans, screening for chromosomal conditions, blood pressure and sugar checks and growth scans later in pregnancy.
Key Takeaways
- Pregnancy after 40 is possible but less likely each month.
- Miscarriage and chromosomal risks are higher.
- Seek specialist advice early.
