Fertility falls sharply in the 40s but doesn't vanish until 12 months after your last period.

FSRH guidance is clear on contraception timing. This guide explains what 'menopausal' fertility really looks like and options if you're still hoping to conceive.

Natural fertility declines rapidly from the mid-30s and even faster after 40 — but it does not vanish on any predictable date. Spontaneous pregnancies in the mid-to-late 40s are uncommon but they do happen, which is why UK contraceptive guidance sets clear rules about when it is finally safe to stop cover. At the same time, if you are actively trying to conceive in your 40s the biological clock is genuinely tight and specialist input early makes a real difference.

FSRH contraception rules — when it is safe to stop

If you have had your last period at age 50 or over: continue contraception for 12 more months.
If your last period was under age 50: continue contraception for 24 more months.
All contraception can be stopped at age 55 regardless of bleeding pattern — spontaneous pregnancy after 55 is exceptionally rare.
FSH blood tests are unreliable for diagnosing menopause while on hormonal contraception; two FSH readings > 30 IU/L, six weeks apart, can support stopping earlier only in specific situations — take specialist advice.

Best contraceptive choices in perimenopause

Mirena intrauterine system: contraception plus endometrial protection if you use HRT — one device, two jobs.
Progestogen-only pill (desogestrel) or implant: safe at any age, ideal if oestrogen is contraindicated.
Copper coil: hormone-free, effective and can stay in until 12 months after the last period if fitted at 40+.
Barrier methods (condoms, diaphragm): fine alongside HRT if hormonal contraception is not wanted.
Combined pill: stop by age 50 in almost all cases due to cardiovascular risk.

If you're still trying to conceive in your 40s

Book an early specialist review — NHS IVF pathways typically end at 42 and private options benefit from prompt investigation.
AMH (anti-Müllerian hormone) and antral follicle count give a useful picture of ovarian reserve.
Time is the single biggest predictor of success — don't wait a year of trying at 42 before seeking help.
Egg or embryo freezing may still be an option in early 40s — outcomes depend on age at freezing, not age at use.

HRT and contraception together

HRT is NOT contraception — the doses of oestrogen and progestogen used for symptom control do not reliably suppress ovulation.
A Mirena coil delivers HRT-grade endometrial protection and full contraception at once — often the neatest solution in perimenopause.
A daily progestogen-only pill can be safely combined with transdermal oestrogen HRT if a Mirena is not wanted.

When to seek a specialist review

Any pregnancy in your 40s — welcome or not — deserves prompt review; risks and follow-up differ from younger pregnancies.
Persistent uncertainty about whether you are still fertile.
Any bleeding on HRT that isn't the expected withdrawal pattern.

Egg quality, egg quantity and what the numbers actually mean

Ovarian reserve (how many eggs you have left) is estimated from AMH plus antral follicle count on ultrasound — it drops sharply through the 40s.
Egg quality (how many of those eggs are chromosomally normal) is the bigger determinant of live-birth rate — and quality falls even faster than quantity.
By age 40, roughly 1 in 2 embryos generated from your own eggs will be aneuploid; by 43, closer to 3 in 4.
AMH cannot tell you whether you will conceive naturally this month — it estimates response to IVF stimulation, not fertility per cycle.
A regular cycle does not equal a fertile cycle — anovulatory cycles become more common in the late 30s and 40s.

Miscarriage and pregnancy risk after 40

Miscarriage risk rises from about 1 in 5 in the early 30s to about 1 in 2 by age 44 — almost entirely driven by egg-quality-related aneuploidy.
Rates of gestational diabetes, pre-eclampsia, placental problems and caesarean delivery are all higher in pregnancies after 40 — this is a case for early consultant-led antenatal care, not a case against pregnancy.
Chromosomal conditions (trisomy 21, 18, 13) are commoner with maternal age; non-invasive prenatal testing (NIPT) is available privately from 10 weeks and often on the NHS if screening is high-risk.
Take 400 mcg folic acid daily from before conception — 5 mg if diabetic, on anti-epileptics, or with a personal or family history of neural tube defects.
Optimise blood pressure, thyroid function, weight and vitamin D pre-conception; small changes now noticeably reduce complication rates later.

Key takeaway

Perimenopausal fertility is low but not zero — plan contraception intentionally, and if you want to conceive, get specialist advice early.

How Dr Awal approaches this in clinic

Every consultation starts with your full story — symptoms, cycle, medical history, family history and what you've already tried. From there we look at whether hormonal treatment, non-hormonal options, lifestyle changes or a combination will give you the best result, and we tailor the plan to your age, risk factors and preferences.

A detailed 60 minute first appointment — no rushed 10-minute slots.
Evidence-based recommendations aligned with NICE NG23 and BMS guidance.
Body-identical HRT considered first-line where appropriate.
Shared-care letters sent to your NHS GP so treatment can continue affordably.
Follow-up at 3 months to fine-tune your regimen and address side effects.
Ongoing annual reviews so your plan evolves with you.

Common questions we hear about this

Do I need to be at a certain age to be seen?

No. We see women in early perimenopause (often late 30s and 40s), through post-menopause and beyond. Age alone doesn't decide whether treatment is right — symptoms, health history and goals do.

Will my GP continue the prescription?

In most cases yes. After your consultation we send a detailed shared-care letter with the diagnosis, treatment plan and rationale so your NHS GP can prescribe on the NHS. Not every practice accepts shared care — we'll discuss this in your appointment.

What if I've tried HRT before and it didn't suit me?

Very common — often the type, dose or route wasn't right rather than HRT itself. We review what you've tried, why it didn't work, and adjust accordingly. Many women who thought HRT wasn't for them do well on a different preparation.

How long will I need to stay on treatment?

There is no set upper time limit for HRT. Current BMS and NICE guidance supports continuing HRT for as long as the benefits outweigh the risks for you personally. We review this together every year so you stay in control of the decision.

Where do you see patients?

All consultations at Pause and Co Healthcare are conducted securely via video, allowing us to support patients anywhere in the UK. Prescriptions and shared care arrangements are managed in the same way, regardless of your location.
