If you’re trying for a baby in your late 30s or 40s, you’re in good company. More people than ever are choosing to start or grow their families later in life, and for many, it’s the right time emotionally, financially, and practically.
But if you’ve heard phrases like “geriatric pregnancy” or been made to feel like time is running out, you’re not alone, and you’re certainly not too late.
This blog explores how age can influence fertility, what’s normal when trying to conceive over 35, and what support is available if things take a little longer.
Is It Harder to Get Pregnant Over 35?
It’s true that fertility does decline with age, especially for women, But this doesn’t mean you can’t get pregnant -it just means your chances per cycle may be slightly lower compared to your 20s.
Here’s what the data shows:
- Around 1 in 4 people will conceive in any given cycle at age 25
- By age 35, this becomes 1 in 5
- At age 40, it’s approximately 1 in 10
So yes, conception may take a little longer after 35, but many people still conceive naturally.

Why Does Fertility Change With Age?
Fertility is influenced by several factors that gradually shift as we get older:
1. Egg Quantity and Quality
You're born with all the eggs you'll ever have. Over time, the number and quality of those eggs naturally declines. Older eggs are more likely to have chromosomal differences, which may increase the risk of miscarriage or conditions like Down’s syndrome.
2. Hormonal Changes
As you age, your hormone levels may fluctuate, which can affect ovulation regularity. Some people start to notice subtle shifts in their cycle length or flow.
3. Increased Risk of Pregnancy Complications
While many people have healthy pregnancies over 35, there is a slightly higher risk of:
- Gestational diabetes
- High blood pressure
- Preterm birth
- Chromosomal conditions
- Antenatal and postnatal depression
Your midwife or GP will monitor these closely, and most pregnancies progress safely with the right care.
How Long Should You Try Before Seeking Help?
The general advice is:
- If you’re under 35, speak to a GP after 12 months of trying
- If you’re 35 or over, seek advice after 6 months of regular unprotected sex without success
This doesn’t mean something is wrong, it’s just that early support may be more helpful as fertility gradually declines with age.
You may be offered:
- Hormone testing
- Ultrasound scans
- Ovarian reserve tests (like AMH or antral follicle count)
- Semen analysis for your partner or donor
Your GP can refer you to a fertility specialist if needed.
Tips to Boost Fertility Over 35 Naturally
While there’s no magic solution, there are plenty of ways to support your reproductive health at any age:
1. Start Preconception Supplements Early
The NHS recommends:
- Folic acid (400mcg) at least 3 months before conception
- Vitamin D (10mcg) daily, especially in winter
2. Track Ovulation
Cycles may become shorter or less predictable with age. Track your fertile window using ovulation predictor kits (OPKs), basal body temperature, or a fertility app.
3. Maintain a Healthy Lifestyle
- Fertility at any age benefits from:
- A nutrient-rich, balanced diet
- Regular, moderate exercise
- Adequate sleep (7–9 hours per night)
- Managing stress and protecting mental wellbeing
- Reducing or eliminating alcohol, smoking, and caffeine
4. Check In With Your GP
Even if you’ve just started trying, it’s okay to speak with your GP about your fertility and ask for advice or reassurance. Your age should never be a barrier to care or compassion.
What About Assisted Conception?
Many people over 35 explore or use assisted reproductive techniques (ART) such as:
- Intrauterine insemination (IUI)
- In vitro fertilisation (IVF)
- Egg or embryo freezing
- Donor sperm or eggs
Success rates vary by age, but modern fertility treatments offer hopeful options, and NHS funding may be available depending on your region and individual circumstances.
