Trying to have a baby is an exciting time, but when pregnancy does not happen as expected, it can also become frustrating and stressful. One of the most common questions couples ask is: “How long should we keep trying before seeing a fertility specialist?”

The answer depends on your age, medical history, menstrual cycles and whether there are known fertility risk factors for either partner.

Infertility is generally defined as not achieving a pregnancy after 12 months of regular, unprotected intercourse. However, you do not always need to wait 12 months. In some circumstances, seeking fertility advice earlier can be important.

Here are 10 signs that it may be time to arrange a fertility assessment.

1. You Have Been Trying for 12 Months Without Pregnancy

If the female partner is under 35 and you have been having regular unprotected intercourse for 12 months without becoming pregnant, it is reasonable to seek a fertility assessment.

This does not necessarily mean that you will need IVF.

A fertility assessment is designed to identify factors that could be making conception more difficult. Depending on the results, treatment may range from lifestyle changes and timing intercourse more accurately to ovulation treatment, surgery, intrauterine insemination (IUI) or IVF.

The important first step is understanding whether there is a problem and, if so, what may be causing it.

2. You Are 35 or Older and Have Been Trying for Six Months

Female age is one of the most important factors influencing fertility.

Women are born with their lifetime supply of eggs. Both the number and, importantly, the quality of those eggs decline with age. The decline becomes more significant during the late 30s and early 40s.

For this reason, women aged 35 years or older are generally advised to seek fertility advice after around six months of trying without success rather than waiting a full year.

Earlier assessment allows you to understand your ovarian reserve and discuss the most appropriate options without unnecessarily losing valuable time.

3. You Are Over 40 and Want to Become Pregnant

If you are over 40 and planning a pregnancy, consider speaking with a fertility specialist early.

You do not necessarily need to spend six or 12 months trying naturally before seeking advice.

A fertility assessment can provide information about ovarian reserve, ovulation, the uterus and fallopian tubes, as well as sperm factors where applicable.

It is important to understand that ovarian reserve tests cannot precisely predict whether an individual woman will become pregnant naturally. However, they can provide useful information when planning fertility treatment.

Early assessment can help you make informed decisions about whether to continue trying naturally or consider fertility treatment.

4. Your Periods Are Irregular or Absent

A regular menstrual cycle is often a useful indicator that ovulation is occurring regularly.

If your periods are very irregular, occur only every few months or have stopped altogether, you may not be ovulating consistently.

Possible causes include:

• Polycystic ovary syndrome (PCOS)
• Significant weight changes
• Excessive exercise
• Thyroid disorders
• Elevated prolactin
• Reduced ovarian function
• Perimenopause
• Other hormonal conditions

The good news is that many causes of irregular ovulation can be investigated and treated.

You do not need to wait 12 months before seeking fertility advice if your periods are significantly irregular or absent.

5. You Have Endometriosis or Significant Pelvic Pain

Endometriosis occurs when tissue similar to the lining of the uterus grows outside the uterus.

It can sometimes affect fertility by causing inflammation, pelvic adhesions, ovarian cysts called endometriomas, or changes around the ovaries and fallopian tubes.

However, having endometriosis does not mean that you cannot become pregnant naturally.

The effect on fertility varies considerably between individuals.

If you have diagnosed endometriosis, significant period pain, pain during intercourse or persistent pelvic pain and are planning a pregnancy, an earlier fertility assessment may be appropriate.

6. You Have Had Previous Pelvic Infection or Surgery

Previous pelvic infections can sometimes damage or block the fallopian tubes.

Similarly, certain operations involving the ovaries, uterus or pelvis may influence fertility.

Risk factors can include a history of:

• Pelvic inflammatory disease
• Chlamydia or gonorrhoea
• Ectopic pregnancy
• Surgery involving the fallopian tubes
• Ovarian surgery
• Significant pelvic surgery

Depending on your history, your fertility specialist may recommend assessment of the fallopian tubes in addition to ultrasound and other investigations.

7. You Have Experienced Recurrent Miscarriages

Miscarriage is unfortunately common, particularly in early pregnancy, and a single miscarriage does not necessarily indicate an underlying fertility problem.

However, recurrent pregnancy loss deserves further assessment.

Depending on your circumstances, investigations may consider factors such as the structure of the uterus, parental chromosomes, thyroid function, antiphospholipid syndrome and other relevant medical conditions.

Female age and embryo chromosome abnormalities are also important contributors to miscarriage risk.

A specialist can review your individual history and determine which investigations are appropriate rather than performing unnecessary tests.

8. There May Be a Male Fertility Problem

Fertility is not solely a female issue.

Male factors contribute to a substantial proportion of couples experiencing infertility, either alone or together with female factors.

Possible warning signs include:

• Previous testicular injury or surgery
• Undescended testes
• Testicular cancer
• Previous chemotherapy or radiotherapy
• Sexual or ejaculation difficulties
• Use of testosterone or anabolic steroids
• Previous abnormal semen analysis

A semen analysis is usually one of the first investigations performed during a fertility assessment.

Importantly, men taking testosterone while trying to conceive should discuss this with an appropriate doctor, because external testosterone can significantly suppress sperm production.

9. You Have Had Cancer Treatment or Are About to Start Treatment

Some chemotherapy, radiotherapy and surgical treatments can affect future fertility.

Whenever possible, fertility preservation should be discussed before cancer treatment begins.

Options may include freezing eggs, sperm or embryos. In selected circumstances, ovarian tissue preservation may also be considered.

The appropriate option depends on factors including age, diagnosis, treatment plan and how quickly cancer treatment needs to commence.

If cancer treatment is planned, fertility specialists can often work closely with the oncology team to minimise unnecessary delays.

10. You Are Concerned About Your Fertility—even Before Trying

You do not have to be infertile to seek fertility advice.

Some people want to understand their fertility before they are ready to have children.

This may be particularly relevant if you are considering delaying pregnancy, have a family history of early menopause, have undergone ovarian surgery or are considering egg or sperm freezing.

A preconception fertility assessment may include discussion of your medical and reproductive history, menstrual cycles, lifestyle and family history.

Depending on your circumstances, investigations may include ultrasound, ovarian reserve testing and semen analysis.

What Happens at a Fertility Assessment?

A fertility assessment should ideally look at both partners, where applicable, rather than focusing only on the woman.

The initial assessment may include:

For women:
A review of menstrual cycles, pregnancy history and medical conditions, pelvic ultrasound, assessment of ovarian reserve where appropriate, and tests to determine whether ovulation is occurring.

For men:
A medical and reproductive history and semen analysis are usually the starting points. Additional hormonal, genetic or ultrasound investigations may be recommended when abnormalities are identified.

For the couple:
The specialist may also assess whether the fallopian tubes are open and whether there are uterine conditions that could affect conception or pregnancy.

Not every patient requires every fertility test. Investigations should be individualised according to your history and circumstances.

Seeing a Fertility Specialist Does Not Automatically Mean IVF

One of the biggest misconceptions about fertility assessment is that seeing a fertility specialist inevitably leads to IVF.

It does not.

Some couples may simply need reassurance and more time. Others may benefit from lifestyle modification, better identification of the fertile window, treatment to restore ovulation or management of an underlying medical condition.

For some people, however, IVF or another form of assisted reproductive treatment may provide the best chance of pregnancy.

The purpose of fertility assessment is to understand why pregnancy may not be occurring and which options are appropriate for you.

The Take-Home Message

Consider seeking fertility advice if:

• You are under 35 and have been trying for 12 months.
• You are 35 or older and have been trying for around six months.
• You are over 40 and planning a pregnancy.
• Your periods are irregular or absent.
• You have endometriosis or significant pelvic pain.
• You have a history of pelvic infection or reproductive surgery.
• You have experienced recurrent pregnancy losses.
• There are concerns about male fertility.
• You are facing treatment that could damage fertility.
• You simply want to understand your reproductive health and future options.

Fertility is highly individual. Seeking advice does not commit you to treatment—it gives you information.

If you are concerned about your fertility, an initial fertility assessment can help you understand where you stand and what your options may be.
