Can a woman get pregnant at 40 or older? Yes, pregnancy is possible, both naturally and with fertility treatment. However, possibility is not the same as probability. Fertility generally declines with age, and after 40, time becomes a more important part of treatment planning.
This is not a reason for panic or shame. It is a reason to obtain an individual assessment promptly and have an honest conversation about the chances, costs, time and trade-offs of each option. Nordica’s fertility over 40 service is designed around this more personalised approach.
Why does fertility decline after 40?
Women are born with their lifetime supply of eggs. As age increases, both the number of remaining eggs and the proportion capable of forming a chromosomally normal embryo decline. Menstrual periods may still be regular even when ovarian reserve is lower, so a regular cycle is not a guarantee of egg quantity or quality.
Age-related changes can lead to:
a lower chance of conception each month;
a lower response to ovarian stimulation for some women;
fewer eggs available for IVF;
a greater chance that an embryo has an abnormal number of chromosomes;
lower implantation and live-birth rates when using older eggs;
a higher risk of miscarriage.
The HFEA’s 2024 UK data reported a much lower average birth rate per embryo transferred with patients’ own eggs at ages 43 to 44 than at ages 18 to 34. These figures should not be copied directly onto an individual Nigerian patient, but the age pattern is clinically important. See HFEA fertility treatment trends for 2024.
When should a woman over 40 seek fertility help?
If you are over 40 and want to conceive, it is reasonable to speak to a fertility specialist now rather than wait for 6 or 12 months. Earlier evaluation does not mean you must start IVF immediately. It helps you understand whether trying naturally for a period is reasonable or whether treatment should be considered sooner.
Evaluation may include a reproductive and pregnancy history, pelvic ultrasound, assessment of the uterus and ovaries, tests related to ovarian reserve and ovulation, and evaluation of the fallopian tubes where relevant. A semen analysis for the male partner should be performed early rather than after months of focusing only on the woman. Nordica outlines common investigations in its guide to fertility tests.
Ovarian reserve tests estimate egg quantity and likely response to stimulation. They do not directly measure the quality of each egg, and no single result can confirm that natural pregnancy is impossible.
Option 1: Timed intercourse and ovulation support
Some women over 40 still ovulate regularly and may conceive naturally. If testing is reassuring, the tubes are open, semen results are suitable and the couple has not been trying for long, a specialist may discuss a short period of well-timed intercourse.
Ovulation induction medication is most relevant when ovulation is irregular or absent. It does not reverse age-related egg changes, and using it when a woman already ovulates will not automatically overcome other causes of infertility. Learn how Nordica uses ovulation induction and cycle monitoring in selected patients.
Option 2: Intrauterine insemination
During IUI, prepared sperm is placed inside the uterus around ovulation. It may be considered when the fallopian tubes are open and sperm parameters are adequate, including in some cases of unexplained infertility or mild male-factor infertility.
For women over 40, the expected live-birth chance per IUI cycle with their own eggs is usually lower than for younger women. Because time matters, a specialist may recommend only a limited number of attempts or advise moving directly to IVF, depending on ovarian reserve, duration of infertility and the couple’s priorities. Read Nordica’s comparison of IUI versus IVF.
Option 3: IVF with your own eggs
IVF allows the fertility team to stimulate the ovaries, retrieve eggs, fertilise them in the laboratory and observe embryo development before transfer. It can bypass blocked tubes and may be appropriate for several female, male or unexplained causes of infertility.
For a woman over 40 who wishes to use her own eggs, an individualised discussion should cover:
likely ovarian response and possible cycle cancellation;
the chance of retrieving no egg or no mature egg;
the possibility that no embryo reaches transfer or freezing;
age-specific pregnancy, miscarriage and live-birth expectations;
whether more than one retrieval may be needed;
the financial and emotional implications of repeated treatment.
IVF does not make an older egg biologically younger. It provides more control over fertilisation and embryo handling, but age-related egg quality remains central. Nordica explains the stages in its IVF process guide.
Option 4: IVF with donor eggs
Donor-egg IVF may offer a higher chance of pregnancy for women whose own-egg prognosis is very low, who have experienced repeated unsuccessful cycles, who have premature ovarian insufficiency, or who risk passing on certain genetic conditions.
The reason outcomes can improve is that embryo potential is strongly linked to the donor’s egg age. HFEA data have shown that birth rates using donor eggs remain more consistent across recipient age groups than rates using patients’ own eggs. Recipient age still matters for pregnancy health, and every woman needs medical assessment before carrying a pregnancy. Read Nordica’s explanation of the egg donation process and its donor egg treatment service.
Donor eggs are a major personal decision. Counselling can help patients consider genetic connection, disclosure to the future child, donor screening, legal documentation and emotional readiness.
Option 5: Donor embryos
Donor embryo treatment may be considered when both egg and sperm donation are needed, or when a patient prefers an embryo donation pathway. It can allow the recipient to carry the pregnancy but does not provide a genetic connection to either intended parent. Availability, screening, consent and legal questions should be discussed carefully. Nordica provides more information about its donor embryo programme.
What about PGT-A after 40?
Preimplantation genetic testing for aneuploidy, or PGT-A, tests cells from an embryo to estimate whether the embryo has the expected number of chromosomes. It may help prioritise which embryo to transfer when several blastocysts are available. It does not improve egg quality or repair an abnormal embryo.
Evidence is nuanced. The HFEA rates PGT-A red for increasing the chance of having a baby for most fertility patients and states that evidence for improving live birth or reducing miscarriage specifically in older women is insufficient for a firm conclusion. ASRM notes possible benefits in selected older cohorts but also calls for careful patient selection. PGT-A may reduce the number of embryos available for transfer and is not useful if there is no blastocyst to test. Patients should discuss the expected benefit for their own embryo numbers, not assume it is compulsory after 40. See the HFEA’s PGT-A evidence summary and Nordica’s overview of preimplantation genetic testing.
Is surrogacy the answer to age-related infertility?
Not usually on its own. A gestational surrogate carries an embryo for the intended parent or parents. Surrogacy may be considered when a woman has no uterus, has a serious uterine condition, has repeated treatment failure linked to the ability to carry a pregnancy, or has a medical condition that makes pregnancy unsafe.
Surrogacy does not make older eggs younger. If embryos are created from a 43-year-old woman’s eggs, the embryo-related effect of egg age remains even if another person carries the pregnancy. Some families may need donor eggs, surrogacy or both, but these solve different clinical problems. Nordica’s surrogacy treatment page explains the pathway, while its article on surrogacy in Nigeria provides further context.
Because the legal framework and parentage arrangements can be complex, intended parents and surrogates should obtain independent legal advice before treatment begins.
Pregnancy health after 40 also matters
Fertility treatment is only one part of the plan. Pregnancy at an older maternal age is associated with higher risks of hypertension, gestational diabetes, pre-eclampsia, Caesarean birth and some fetal complications. Most women over 40 do not experience every complication, but preconception assessment is important.
Before treatment, the clinical team may review blood pressure, weight, diabetes risk, current medicines, previous pregnancies and other medical conditions. The goal is not to exclude patients simply because of age. It is to choose a safe treatment and pregnancy plan.
How to choose the best fertility treatment over 40
There is no single “best” option for every woman. A useful decision combines four things: medical findings, realistic probabilities, personal values and available resources.
Ask your fertility specialist:
1. What is my chance of live birth with my own eggs per cycle started and cumulatively?
2. How many eggs do you reasonably expect to retrieve?
3. Would IUI use valuable time in my case?
4. When would you recommend discussing donor eggs?
5. Is any proposed test or add-on supported by evidence for someone with my profile?
6. Am I medically ready to carry a pregnancy?
7. What would make us stop, change direction or seek another opinion?
Clear answers help replace vague hope with informed hope.
Frequently asked questions
Can I get pregnant naturally at 40?
Yes, but the monthly chance is lower than at younger ages and varies between individuals. Seek prompt assessment if pregnancy is a current goal.
Is 42 too old for IVF?
Age 42 does not automatically rule out IVF. The expected outcome with your own eggs may be low, so ovarian reserve, medical history, previous response and alternatives such as donor eggs should be discussed honestly.
Does AMH show egg quality?
No. AMH mainly helps estimate ovarian reserve and response to stimulation. Age remains a stronger general indicator of the likelihood of chromosomal problems in eggs.
Can supplements improve egg quality after 40?
No supplement can reverse egg age or guarantee a chromosomally normal embryo. Discuss supplements with your doctor because evidence, product quality and interactions vary.
