Being pregnant at 45 is possible, but the natural chance of conceiving each month is low, generally estimated at around one to two percent, mainly because both the number and quality of eggs decline sharply with age. Many women in this position turn to fertility treatment, including donor eggs, to improve their chances of a successful pregnancy.
Why Fertility Declines by 45
You are born with all the eggs you will ever have, and both the quantity and genetic quality of those eggs reduce steadily over time. By your mid-40s, a much higher proportion of remaining eggs carry chromosomal abnormalities compared to your 20s and early 30s, which makes both conceiving and carrying a pregnancy to term more difficult. This is a biological process rather than something related to general health or fitness.
What the Numbers Generally Show
- Natural conception chances at 45 are typically estimated at around one to two percent per cycle
- The risk of miscarriage rises considerably with age, reaching around 40 percent or higher in your 40s
- NHS funded IVF is usually only offered up to a certain age, often 42, meaning most fertility treatment after this point is arranged privately
- Using donor eggs from a younger woman significantly improves the chance of a successful pregnancy compared with using your own eggs at 45
Options If You Are Trying to Conceive at 45
- Natural conception. Still possible for some women, particularly if ovulation remains regular, though the odds are low and patience alone rarely resolves this.
- IVF using your own eggs. Success rates are considerably lower at this age due to egg quality, though it does work for some women.
- IVF using donor eggs. Often recommended at this stage, as it removes the age related decline in egg quality from the equation and offers notably higher success rates.
- Fertility testing first. An ovarian reserve test and general health check can help you understand your individual situation before deciding which route to pursue.
Health Considerations for Pregnancy at 45
A pregnancy at 45 is generally considered higher risk and is usually monitored more closely than a pregnancy at a younger age. Increased risks can include high blood pressure, gestational diabetes, and a higher likelihood of needing a caesarean section. This does not mean a healthy pregnancy is not achievable, but it does mean closer, specialist care matters more at this stage.

Why Speaking to a Specialist Early Helps
If you are considering trying to conceive at 45, getting fertility testing done sooner rather than later gives you a clearer picture of your options while there is still time to act on the results. A gynaecologist or fertility specialist can talk you through realistic expectations and the treatments most likely to help in your specific situation.
Frequently Asked Questions
What are my realistic chances of a natural pregnancy at 45? Most estimates put natural conception chances at around one to two percent per cycle, though this varies depending on individual ovarian reserve and health.
Does IVF definitely work better than trying naturally at 45? IVF using your own eggs still faces the same age related egg quality issues, so success rates remain relatively low. IVF using donor eggs generally offers a much higher chance of success.
Is pregnancy more dangerous for me at 45? It carries higher risks such as high blood pressure and gestational diabetes, but with specialist monitoring, many women have safe pregnancies at this age.
Should I get fertility testing before trying to conceive at 45? Yes, this gives you a realistic understanding of your ovarian reserve and helps guide which options are most likely to work for you.
Can lifestyle changes improve my chances at 45? Maintaining a healthy weight, avoiding smoking, and managing stress can support overall health, but they cannot reverse the natural decline in egg quality that comes with age.
Conclusion
Having a baby at 45 is possible, but it comes with lower natural odds and higher risks that are worth understanding clearly before you start trying.
