When you're trying to conceive (TTC) and it's not happening as quickly as you'd hoped, one of the most common questions is: When should I see a doctor?
The answer depends on your age, how long you've been trying, and whether you have any known risk factors. But here's the most important thing to know: seeking fertility help isn't "giving up"—it's taking proactive steps to understand your body and get support if you need it.
This guide explains the NHS guidelines for when to seek fertility advice, what the GP appointment and referral process looks like, what tests you can expect, and how to navigate UK fertility services.
NHS Guidelines: When to See Your GP
The NHS provides clear guidance on when to seek fertility help:
If You're Under 35
Timeline: After 12 months of regular, unprotected intercourse without conceiving.
What "regular intercourse" means:
Sex every 2-3 days throughout your cycle, or at minimum during your fertile window (the 5-6 days ending on ovulation day).
Why 12 months?
For healthy couples under 35, about 80-85% will conceive within one year. If you haven't conceived after 12 months, there may be an underlying issue worth investigating.
If You're 35 or Older
Timeline: After 6 months of regular, unprotected intercourse without conceiving.
Why the shorter timeline?
Fertility declines more rapidly after 35, and egg quality decreases. The NHS recognizes that time is more important for women over 35, so the recommendation is to seek help sooner.
If You're 40 or Older
If you're 40 or over and trying to conceive, it's sensible to speak to your GP as soon as possible rather than waiting 6–12 months...
Why?
At 40+, natural fertility is significantly lower, and time is critical. Your GP can run initial tests right away and refer you promptly if needed.
When to See Your GP Sooner (Regardless of Age)
You should see your GP before the standard 6-12 month timeline if:
1. You Have Irregular or Absent Periods
Why it matters:
If your periods come fewer than 9 times per year, more than 13 times per year, or vary wildly in length (e. g., 25 days one month, 45 days the next), you may not be ovulating regularly—or at all.
Common causes:
- Polycystic ovary syndrome (PCOS)
- Thyroid disorders
- Premature ovarian insufficiency
- Stress, low body weight, or excessive exercise
What your GP can do:
Blood tests to check if you're ovulating and measure hormone levels (FSH, LH, thyroid hormones, prolactin).
2. You Have a Known Condition Affecting Fertility
See your GP before trying or immediately after starting if you have:
- PCOS – May need medication to induce ovulation
- Endometriosis – Can affect egg quality and implantation
- Previous pelvic surgery – May have caused scarring or blocked tubes
- History of pelvic inflammatory disease (PID) or STIs – Risk of tubal damage
- Thyroid disorder – Needs to be well-controlled before and during pregnancy
- Diabetes – Requires preconception planning
Your GP can:
- Optimize management of existing conditions
- Check if conditions are affecting fertility
- Refer you earlier for fertility testing
3. Your Partner Has Known Fertility Issues
See your GP sooner if your partner has:
- Previous low sperm count or abnormal semen analysis
- History of testicular injury, surgery, or cancer treatment
- Genetic conditions affecting fertility
- Erectile dysfunction or ejaculation problems
What your GP can do:
Arrange semen analysis or refer your partner to a urologist or fertility specialist.
4. You're Not Sure If You're Ovulating
Signs you might not be ovulating:
- Very irregular periods
- No fertile cervical mucus (egg-white consistency)
- Consistently negative ovulation predictor tests
- No temperature shift on basal body temperature charts
What your GP can do:
Blood test on day 21 of your cycle (or 7 days before expected period) to measure progesterone. Low progesterone suggests you didn't ovulate that cycle.
See our guide: Understanding Your Menstrual Cycle When Trying to Conceive: UK Guide
5. You Have Very Painful or Heavy Periods
Why it matters:
Severe period pain, very heavy bleeding, or pain during sex can indicate endometriosis, which affects fertility.
What your GP can do:
Pelvic examination, ultrasound, and referral to gynecology if endometriosis is suspected.
What Happens at Your First GP Appointment
Don't be nervous—GPs see fertility concerns regularly, and this is a routine appointment.
What to Bring
Information your GP will want:
- How long you've been trying (month/year you started)
- Your cycle length and regularity
- Any previous pregnancies (you or your partner)
- Medical history (surgeries, chronic conditions, medications)
- Your partner's medical history (if relevant)
- Lifestyle factors (smoking, alcohol, weight)
Optional but helpful:
- A few months of cycle tracking (period dates, ovulation tests)
- List of any symptoms (pain, irregular bleeding, etc.)
What Your GP Will Ask
Expect questions about:
- How long you've been trying and how often you have sex
- Your menstrual cycle (length, regularity, symptoms)
- Previous pregnancies, miscarriages, or terminations
- Contraception history (what you used, when you stopped)
- Medical conditions or surgeries
- Medications or supplements you're taking
- Family history of fertility issues or early menopause
- Lifestyle (smoking, alcohol, exercise, stress)
- Your partner's health and fertility history
Be honest. Your GP isn't judging—they need accurate information to help you.
Initial Tests Your GP May Offer
At the first appointment or shortly after, your GP can arrange:
For you:
- Blood tests to check:
- Day 21 progesterone (confirms ovulation)
- Thyroid function (TSH, T4)
- Prolactin (hormone that can affect ovulation)
- FSH and LH (on days 2-5 of your cycle - assesses ovarian reserve)
- AMH (Anti-Müllerian Hormone) – Optional, assesses egg reserve (not always offered on NHS)
- Rubella immunity check (German measles) – If not immune, you'll need vaccination before pregnancy
- STI screening if there's any history of pelvic infections
For your partner:
- Semen analysis – Checks sperm count, motility (movement), and morphology (shape)
These tests are available on the NHS and are usually free.
What Happens Next
If tests are normal:
Your GP may advise continuing to try for a few more months while optimizing timing (sex during fertile window), lifestyle (healthy weight, no smoking), and supplements (folic acid).
If tests show an issue:
Your GP will either treat the issue (e. g., thyroid medication) or refer you to a fertility specialist for further investigation and treatment.
If you meet NHS criteria for fertility treatment:
Your GP will refer you to an NHS fertility clinic. Waiting times vary by region (typically 3-12 months).
NHS Fertility Referral: What to Expect
Eligibility for NHS-Funded Fertility Treatment
Fertility treatment on the NHS is available, but access depends on local policy. In England, each Integrated Care Board (ICB) sets its own funding criteria, based on NICE guidance but adapted to local budgets.
That means eligibility can vary depending on where you live.
Because policies differ, your GP or local fertility clinic is the best source of accurate information for your postcode.
What Happens at the Fertility Clinic
Your first fertility clinic appointment (often called a "fertility MOT") will include:
1. Detailed medical history
More in-depth than the GP appointment—covering full reproductive history, lifestyle, and previous test results.
2. Physical examination
Usually not invasive at the first appointment, but may include checking BMI, blood pressure, etc.
3. Further tests (if not already done):
- For you:
- Pelvic ultrasound (checks ovaries, uterus, looks for fibroids or cysts)
- Hysterosalpingogram (HSG) or HyCoSy – X-ray or ultrasound to check if fallopian tubes are open
- Additional blood tests if needed
- For your partner:
- Repeat semen analysis if first test was abnormal
- Hormone tests if sperm count is very low
4. Diagnosis and treatment plan
Based on test results, the specialist will explain:
- What's causing the fertility issue (if identified)
- Treatment options available on NHS
- Expected success rates
- Next steps
Common Fertility Treatments on NHS
Depending on diagnosis, NHS may offer:
1. Ovulation induction (e. g., Clomid, Letrozole)
For women not ovulating due to PCOS or other causes.
2. Intrauterine insemination (IUI)
Sperm placed directly into uterus—used for mild male factor infertility or unexplained infertility.
3. In vitro fertilization (IVF)
Eggs retrieved, fertilized in lab, embryo transferred to uterus. Offered for tubal blockage, severe male factor, endometriosis, or unexplained infertility after other treatments fail.
4. Intracytoplasmic sperm injection (ICSI)
Single sperm injected into egg—used for severe male factor infertility.
NHS typically funds 1-3 IVF cycles depending on your age and local CCG policy.
NHS Waiting Times
Waiting times vary by region and can be:
- GP to fertility clinic referral: 3-12 months
- First fertility appointment to starting treatment: 3-6 months
- Total time from GP to IVF: Often 12-18 months
If you're over 35 or 40, waiting times can feel frustrating given age-related fertility decline.
Private Fertility Care: The Alternative
If you don't qualify for NHS treatment, prefer not to wait, or want more options, private fertility care is an alternative.
When to Consider Private Care
You might choose private fertility treatment if:
- You don't meet NHS criteria (e. g., have children, BMI outside range, partner smokes)
- Waiting times are too long given your age
- You want access to more advanced treatments or tests
- You want more personalized care or flexibility
Costs of Private Fertility Treatment
Private fertility treatment is expensive. Approximate costs:
Consultations & tests:
- Initial consultation: £150-300
- Pelvic ultrasound: £150-250
- Hysterosalpingogram (HSG): £300-600
- Full fertility assessment: £500-1,500
Treatments:
- Ovulation induction (medication only): £50-200 per cycle
- IUI: £800-1,500 per cycle
- IVF: £4,000-8,000 per cycle (including medications)
- ICSI: £5,000-9,000 per cycle
- Frozen embryo transfer (FET): £1,500-3,000
Add-ons (optional):
- Embryo freezing: £500-1,000
- Genetic testing (PGT-A): £2,000-4,000
- Endometrial scratch, assisted hatching, etc.: £200-500 each
Total costs for one IVF cycle can easily exceed £10,000 with medications and add-ons.
How to Choose a Private Fertility Clinic
Things to consider:
- Success rates: Check clinic-specific data on HFEA website (Human Fertilisation and Embryology Authority)
- Location: Frequent appointments required—choose somewhere accessible
- Costs: Get itemized quotes from multiple clinics
- Reputation: Read reviews, ask for recommendations in TTC forums
- Personal fit: Do you feel comfortable with the consultant?
Reputable UK fertility clinic chains include:
- Care Fertility
- London Women's Clinic
- CRGH (Centre for Reproductive and Genetic Health)
- CREATE Fertility
- Bourn Hall
- Regional NHS hospitals offering private treatment
What If Tests Show "Unexplained Infertility"?
About 25-30% of couples receive a diagnosis of "unexplained infertility"—all tests come back normal, but pregnancy still isn't happening.
This doesn't mean nothing is wrong. It means current tests haven't identified the issue. Possible causes that standard tests don't detect:
- Egg quality issues (especially age-related)
- Subtle problems with implantation
- Immunological factors
- Genetic factors
- Sperm DNA fragmentation (not tested in standard semen analysis)
Treatment for unexplained infertility:
- Continue trying naturally with optimized timing
- Ovulation induction (even if you're ovulating)
- IUI (can improve chances by 5-10% per cycle)
- IVF (bypass unknown issues—success rates 25-40% per cycle depending on age)
Don't be discouraged by "unexplained." Many couples with this diagnosis conceive naturally or with treatment.

Questions to Ask Your GP or Fertility Specialist
Don't be afraid to ask questions. Here are good ones:
About diagnosis:
- What test results indicate a problem?
- What's causing our fertility issue?
- Are there lifestyle changes we should make?
About treatment:
- What treatment do you recommend and why?
- What are the success rates for our situation?
- What are the side effects or risks?
- How long does treatment take?
- What happens if this treatment doesn't work?
About NHS/private care:
- Do we qualify for NHS-funded treatment?
- How long is the waiting list?
- What would private treatment cost?
- Can we start privately and transfer to NHS later?
About next steps:
- What should we do while waiting for appointments/treatment?
- When should we follow up?
- Are there any tests we can do privately to speed things up?
Mental Health and Fertility Treatment
Fertility struggles and treatment can be emotionally draining.
It's normal to feel:
- Anxious about appointments and test results
- Frustrated by waiting times
- Sad or grieving when treatments fail
- Isolated from friends who conceive easily
- Stressed by the financial and physical demands
Support available:
- NHS talking therapies (free counseling)
- Fertility Network UK (support groups, forums)
- Fertility counseling (offered by some NHS and private clinics)
Don't suffer in silence. Seeking emotional support is as important as medical treatment.

Key Takeaways
1. Don't wait too long to seek help
If you're under 35, see your GP after 12 months. If you're 35+, see them after 6 months. If you have known risk factors, see them sooner.
2. Your GP is the first step
They can run initial tests and refer you to a fertility specialist if needed. NHS fertility care is available—use it.
3. Tests are straightforward
Blood tests, semen analysis, and ultrasounds are simple and give valuable information. Don't fear them.
4. Many fertility issues are treatable
Ovulation problems, mild male factor, and even tubal blockages often respond to treatment. Early diagnosis improves outcomes.
5. Private care is an option
If you don't qualify for NHS or can't wait, private fertility care provides faster access and more options—but it's expensive.
6. You're not alone
About 1 in 7 UK couples experience fertility difficulties. Support is available, and seeking help is a sign of strength, not failure.
Final Thoughts
Deciding when to see a fertility doctor isn't always straightforward, especially when you're anxious about what tests might reveal or worried about seeming "impatient." But here's the truth: there's no benefit to waiting longer than the NHS guidelines recommend.
If you've been trying for the recommended time (6-12 months depending on age), or if you have risk factors, seeing your GP is the smart, proactive choice. Early diagnosis often means more treatment options and better outcomes.
Fertility care in the UK—whether NHS or private—has improved dramatically in recent decades. Many couples who once would have struggled for years now conceive with relatively simple interventions.
You deserve support, answers, and a clear path forward. Don't wait.
