Trying to conceive can be an exciting stage of life, but it can also become stressful when pregnancy does not happen as expected. Some couples may choose to wait longer, while others may wonder whether it is time to seek professional advice.
There is no single waiting period that applies to everyone. Age, menstrual history, previous pregnancies, medical conditions and factors affecting the male partner can all influence when a fertility assessment should begin.
In Singapore, the Ministry of Health (MOH) advises couples to seek medical advice if the woman is below 35 and has been trying to conceive for one year, or if she is above 35 and has been trying for six months without achieving pregnancy.
However, you may not need to wait six or 12 months if you already have a known condition or medical history that could affect fertility.
What Does a Fertility Specialist Do?
A fertility specialist assesses and manages problems that may make it difficult to conceive.
Depending on the circumstances, a fertility specialist may investigate factors affecting:
- Ovulation
- Ovarian reserve
- Fallopian tubes
- Uterus
- Sperm production
- Sperm movement and quality
- Hormonal function
- Sexual or reproductive health
Fertility problems can affect either partner, both partners or sometimes have no immediately identifiable cause. SingHealth notes that infertility may result from male factors, female factors or a combination of factors, while some couples may have no obvious cause identified after assessment.
A fertility specialist may therefore recommend evaluating both partners rather than focusing only on the woman.
How Long Should You Try to Conceive Before Seeking Help?
The appropriate timeframe depends largely on the woman’s age.
If the Woman Is Under 35
MOH recommends seeking medical advice after 12 months of trying to conceive without pregnancy.
This does not mean a couple must necessarily wait exactly 12 months before speaking to a doctor if there are existing concerns.
For example, earlier assessment may be appropriate if there is:
- Irregular or absent menstruation
- A known reproductive condition
- Previous pelvic surgery
- A history of recurrent pregnancy loss
- Previous cancer treatment
- A known fertility problem affecting either partner
If the Woman Is 35 or Older
MOH recommends seeking medical advice after six months of trying without pregnancy.
This shorter timeframe reflects the effect of age on female fertility.
Egg number and quality decline with age, so delaying assessment may reduce the time available to investigate and address potential fertility issues.
Should You See a Fertility Specialist Before Trying for Six or 12 Months?
Sometimes, yes.
The six- or 12-month timeframe is a general guide for couples without known fertility risk factors. It does not mean that everyone should wait before seeking medical advice.
You may benefit from an earlier consultation if you already know that you have a condition that could affect fertility.
1. You Have Irregular or Absent Periods
Menstrual cycles can provide clues about whether ovulation is occurring regularly.
Irregular or absent periods may be associated with conditions affecting ovulation, including:
- Polycystic ovary syndrome (PCOS)
- Certain hormonal disorders
- Significant changes in body weight
- Thyroid disorders
- Other reproductive or endocrine conditions
If your periods are consistently irregular, you may wish to seek assessment rather than waiting until you have tried to conceive for a full year.
A fertility specialist can investigate whether ovulation is occurring and whether there may be an underlying cause.
2. You Have a History of Endometriosis
Endometriosis occurs when tissue similar to the lining of the uterus grows outside the uterus.
It may be associated with:
- Painful periods
- Pelvic pain
- Pain during sexual intercourse
- Ovarian endometriomas
- Difficulty conceiving
Not everyone with endometriosis will experience infertility, but the condition can affect reproductive function.
If you have known or suspected endometriosis and are planning a pregnancy, discussing your reproductive plans with a doctor may be appropriate.
3. You Have Had Previous Pelvic or Reproductive Surgery
Previous surgery involving the:
- Ovaries
- Fallopian tubes
- Uterus
- Pelvis
may be relevant when assessing fertility.
It is recommended to have earlier fertility assessment for women who have undergone previous operations involving the ovaries, fallopian tubes or uterus.
Depending on the procedure, surgery may affect ovarian reserve, the fallopian tubes or the structure of the reproductive organs.
4. You Have Experienced Recurrent Pregnancy Loss
Difficulty conceiving is not the only reason to seek fertility care.
Some couples can become pregnant but experience repeated miscarriages.
If you have experienced recurrent pregnancy losses, discussing your reproductive history with a specialist may help determine whether further evaluation is appropriate.
The assessment may consider factors involving:
- The uterus
- Hormones
- Chromosomal factors
- Other medical conditions
The appropriate investigations depend on the individual’s history.
5. You Have Previously Received Cancer Treatment
Some cancer treatments can affect reproductive function.
Depending on the treatment received, fertility may be affected by:
- Chemotherapy
- Radiotherapy
- Certain surgical procedures
If you have previously undergone cancer treatment and are considering pregnancy, a fertility consultation can help assess your reproductive options.
This can also be relevant for people considering fertility preservation before cancer treatment.
6. You Have Concerns About Your Ovarian Reserve
Ovarian reserve refers to the remaining supply of eggs within the ovaries.
It generally declines with age, although the rate varies between individuals.
Tests such as anti-Müllerian hormone (AMH) may be used as part of an assessment of ovarian reserve in appropriate circumstances.
However, AMH should not be interpreted as a standalone test that can predict whether someone will naturally conceive.
MOH states that fertility assessments, including tests such as AMH and FSH, should be individualised and ordered when clinically indicated rather than used as universal screening for the general population.
7. Your Partner Has a Known Fertility Concern
Fertility assessment should involve both partners when appropriate.
Male fertility factors may include:
- Low sperm count
- Poor sperm movement
- Abnormal sperm morphology
- Previous testicular problems
- Varicocele
- Erectile difficulties
- Ejaculatory problems
A previous abnormal semen analysis is also a reason to seek medical advice.
Male factors can contribute to infertility and recommends assessment where there are concerns involving sexual function, testicular health or sperm quality.
8. You Have Difficulty With Sexual Intercourse
Problems that make regular intercourse difficult can affect the chances of conception.
These may include:
- Erectile dysfunction
- Difficulty with ejaculation
- Pain during intercourse
- Vaginismus
- Significant reduction in libido
These concerns do not necessarily mean that pregnancy is impossible, but they may warrant medical assessment.
Treatment may involve addressing the sexual or reproductive problem itself rather than immediately proceeding to fertility treatment.
9. You Have Had a Previous Fertility Test With an Abnormal Result
If you have previously undergone:
- Semen analysis
- Hormonal testing
- Pelvic ultrasound
- Ovarian reserve testing
- Fallopian tube assessment
and received an abnormal result, it may be appropriate to discuss the findings with a fertility specialist.
An abnormal test does not necessarily mean that pregnancy cannot occur.
The significance of a result depends on:
- Age
- Other test results
- Medical history
- Whether the test was performed for a specific reason
10. You Have Been Trying for the Recommended Period Without Pregnancy
For couples without known risk factors, this is one of the clearest reasons to seek help.
In Singapore, MOH recommends medical advice after:
12 months of trying if the woman is below 35, or
6 months of trying if the woman is above 35.
At this point, an assessment can help determine whether there is a treatable cause and whether further fertility treatment may be appropriate.
What Happens During a Fertility Consultation?
A fertility consultation usually begins with a detailed review of both partners’ medical and reproductive histories.
The specialist may ask about:
- How long you have been trying
- Menstrual cycle patterns
- Previous pregnancies
- Previous miscarriages
- Previous surgeries
- Medical conditions
- Medications
- Previous fertility tests
- Sexual frequency and difficulties
The aim is to identify factors that may affect conception and determine which investigations are appropriate.
What Fertility Tests May Be Recommended?
Testing is individualised rather than identical for every couple.
For Women
Depending on the circumstances, assessment may include:
Blood Tests
These may evaluate:
- Ovulation
- Ovarian reserve
- Thyroid function
- Other reproductive hormones
Pelvic Ultrasound
An ultrasound may assess:
- Ovaries
- Uterus
- Fibroids
- Ovarian cysts
- Other structural abnormalities
Fallopian Tube Assessment
Tests may be recommended to determine whether the fallopian tubes are open.
These may include:
- Hysterosalpingography
- Saline infusion sonography
- Other appropriate imaging techniques
For Men
A semen analysis is commonly used to assess male fertility.
It can provide information about:
- Sperm concentration
- Sperm movement
- Sperm morphology
Additional testing may be recommended depending on the findings and medical history.
Does Seeing a Fertility Specialist Mean You Need IVF?
No. Seeing a fertility specialist does not automatically mean that you will need IVF.
Treatment depends on the cause of the fertility problem and may include:
- Timing intercourse around ovulation
- Treatment for ovulation problems
- Management of underlying medical conditions
- Surgery for selected reproductive conditions
- Intrauterine insemination (IUI)
- IVF
- ICSI in selected situations
Some couples may conceive naturally after an underlying issue is identified and treated.
The purpose of a fertility consultation is to understand the situation and determine the most appropriate next step.
When Might IVF Be Considered?
IVF may be discussed when other approaches are unlikely to be effective or have not resulted in pregnancy.
Potential reasons may include:
- Blocked or severely damaged fallopian tubes
- Certain male-factor fertility problems
- Some cases of endometriosis
- Reduced ovarian reserve or age-related fertility decline
- Unexplained infertility after appropriate evaluation
- Previous unsuccessful fertility treatments
The decision depends on the couple’s individual circumstances rather than simply the number of months they have been trying.
Why Does Age Matter When Seeking Fertility Help?
Female fertility changes with age because both the number and quality of eggs decline over time.
This does not mean that pregnancy is impossible after 35. However, age becomes increasingly relevant when deciding how long to wait before seeking assessment.
MOH specifically recommends seeking medical advice after six months of trying for women above 35 rather than waiting for a full year.
Current Singapore data also demonstrates that IVF outcomes vary considerably with maternal age, reinforcing why age is an important consideration in fertility planning and treatment discussions.
Should Men Also See a Fertility Specialist?
Yes, when there are concerns about male fertility.
Infertility is not exclusively a female issue. Male factors may contribute to difficulty conceiving, either alone or together with female factors.
A male fertility assessment may be appropriate if there is:
- A previous abnormal semen analysis
- History of testicular injury
- Previous testicular surgery
- Varicocele
- Erectile dysfunction
- Ejaculatory difficulties
- Certain hormonal conditions
- Previous cancer treatment
Assessing both partners can help avoid unnecessary delays in identifying the cause.
Can Lifestyle Factors Affect Fertility?
Lifestyle factors may influence fertility in both men and women.
Potential factors include:
- Smoking
- Excessive alcohol consumption
- Being overweight or underweight
- Poor sleep
- Certain recreational drugs
- High levels of physical or psychological stress
Lifestyle changes may support fertility, but they should not be used as a reason to delay medical assessment when there are established risk factors or when the recommended timeframe for seeking help has been reached.
Should You Get Fertility Screening Before Trying to Conceive?
Routine fertility screening is not currently recommended for everyone simply because they are planning a pregnancy.
MOH states that fertility assessment is individualised because fertility concerns depend on the specific circumstances of the couple. It does not recommend general population fertility screening simply for early detection in people without relevant indications.
However, a preconception consultation may be useful if you have:
- A known reproductive condition
- Previous fertility problems
- Previous pelvic surgery
- A history of cancer treatment
- Concerns about reproductive health
- Plans to delay pregnancy
A doctor can determine whether any assessment is clinically appropriate.
How Can You Prepare for a Fertility Consultation?
Before your appointment, it may be useful to prepare:
- Menstrual cycle dates
- Previous pregnancy history
- Previous miscarriage or ectopic pregnancy history
- Previous medical or surgical records
- Previous fertility test results
- Medication and supplement list
- Partner’s relevant medical history
You may also wish to write down questions about:
- Your fertility outlook
- Recommended tests
- Possible treatment options
- Timing of treatment
- Whether fertility preservation should be considered
Having this information available can make the consultation more productive.
Knowing when to see a fertility specialist can help couples avoid unnecessary delays while also avoiding tests or treatments that may not be clinically necessary.
In Singapore, MOH recommends seeking medical advice after 12 months of trying to conceive if the woman is below 35, or after six months if she is above 35. Earlier assessment may be appropriate when there are known fertility risk factors, reproductive conditions, previous pelvic surgery, recurrent pregnancy loss or concerns affecting either partner.
A fertility consultation does not automatically mean IVF. The first step is usually understanding the couple’s medical and reproductive history and determining whether further testing is appropriate. Depending on the findings, management may range from addressing an underlying condition and lifestyle factors to fertility treatments such as IUI or IVF.
If you are concerned about your ability to conceive, speaking with a fertility specialist can help you understand your individual circumstances and determine when further assessment or treatment may be appropriate.
