Fertility and Age: When to Seek Assessment and What May Be Discussed

Trying for a baby can feel very private, yet the questions that come up are often shared by many couples: “Are we too early to check?”, “Is age affecting our chances?”, “What tests will the doctor suggest?” In Singapore, fertility assessment is usually approached step by step, with both partners considered where relevant.

Age matters, but it is only one part of fertility

Age is one of the most discussed factors in fertility because egg quantity and egg quality tend to decline over time. This decline is usually more noticeable from the mid-30s onwards, and faster after the late 30s. For sperm, age can also play a role, although the pattern is different. Sperm quality may change gradually with age and health factors.

Still, age alone does not tell the whole story. Fertility can also be affected by:

• Ovulation patterns

• Fallopian tube health

• Uterine conditions such as fibroids or polyps

• Endometriosis

• Sperm count, movement and shape

• Sexual timing and frequency

• Weight, smoking, alcohol intake and other lifestyle factors

• Past infections, surgery or cancer treatment

• Medical conditions such as thyroid disease or diabetes

  
  

Some couples conceive quickly at a later age. Some younger couples need medical support. This is why fertility and age should be discussed together with personal medical history, menstrual patterns and partner factors.

A fertility assessment does not mean someone has already “failed” to conceive. It is a way to understand what may be affecting the chance of pregnancy and what options are appropriate.

When to seek assessment

Many international guidelines suggest seeking medical assessment after 12 months of regular unprotected intercourse if the female partner is under 35. If the female partner is 35 or older, assessment is often suggested after 6 months.

For those aged 40 or above, earlier discussion with a doctor is usually sensible because time becomes a more important factor in planning.

There are also situations where it is reasonable to seek help earlier, regardless of age.

These include:

• Irregular or absent periods

• Very painful periods or suspected endometriosis

• Known polycystic ovary syndrome

• Previous pelvic infection

• Previous ectopic pregnancy

• History of pelvic or abdominal surgery

• Known fibroids affecting the womb cavity

• Recurrent miscarriage

• Difficulty with intercourse or ejaculation

• Known low sperm count or previous abnormal semen analysis

• Cancer treatment, chemotherapy or radiotherapy history

• A medical condition that may affect pregnancy planning

  
  

If there is uncertainty, a preliminary consultation can help clarify whether testing is needed now or whether timed intercourse and monitoring may be reasonable for a while longer.

What a female fertility evaluation may include

A fertility assessment usually starts with a detailed history. The clinician may ask about menstrual cycles, period pain, previous pregnancies, medical conditions, medications, surgery and how long the couple has been trying.

A physical examination may be recommended, depending on the situation. From there, investigations may be planned.

Common parts of a female fertility evaluation may include:

Ovulation assessment

This may involve cycle history, urine ovulation kits, blood tests at certain points in the cycle, or ultrasound monitoring. The aim is to see whether ovulation is likely happening and whether timing can be improved.

Pelvic ultrasound

An ultrasound can assess the uterus and ovaries. It may show fibroids, ovarian cysts, signs that may suggest polycystic ovaries, or other structural findings. A normal ultrasound is reassuring, but it does not rule out every cause of infertility.

Hormonal blood tests

Doctors may check hormones related to ovulation, thyroid function or prolactin levels. The exact tests depend on cycle pattern and symptoms.

Fallopian tube assessment

Pregnancy usually requires at least one open fallopian tube. A doctor may discuss a dye test, such as hysterosalpingography, or other imaging methods to assess whether the tubes appear open.

Uterine cavity assessment

If there are concerns about polyps, fibroids or scarring inside the womb, further tests may be discussed. This may include saline ultrasound or hysteroscopy, depending on the clinical picture.

Not every person needs every test. A good evaluation should be guided by age, history, symptoms and how long pregnancy has been attempted.

What a male fertility evaluation may include

Male factors contribute to many cases of infertility, either alone or together with female factors. For this reason, assessment of the male partner is often done early. It is not about blame. It is about having a complete picture.

The most common first test is a semen analysis. This looks at several features, including:

• Semen volume

• Sperm concentration

• Sperm movement

• Sperm shape

• Other features that may suggest inflammation or collection issues

  
  

Because semen results can vary, a repeat test may be advised if the first result is abnormal or borderline. Collection method, recent fever, illness, medications and timing since last ejaculation can affect results.

A doctor may also ask about:

• Past testicular injury or surgery

• Varicocele

• Childhood undescended testes

• Infections

• Erectile or ejaculation concerns

• Smoking, alcohol and anabolic steroid use

• Heat exposure

• Medical conditions and medications

  
  

Some men may be referred to a urologist or andrologist for further evaluation, especially if semen parameters are very low, if there is pain or swelling, or if hormonal or genetic testing is being considered.

What ovarian reserve tests can and cannot tell you

Ovarian reserve testing often comes up when discussing age and fertility. Common tests include anti-Müllerian hormone, often called AMH, and antral follicle count through ultrasound.

These tests can be useful, especially when planning fertility treatments such as IVF. They may help doctors estimate how the ovaries might respond to stimulation medication. They may also guide treatment planning and counselling.

But ovarian reserve tests have limits.

A low AMH or low antral follicle count does not prove that natural pregnancy cannot happen. A higher result does not guarantee easy conception. These tests do not measure egg quality directly, and they do not assess sperm, fallopian tubes, ovulation timing, implantation or the uterus.

In simple terms, ovarian reserve tests provide one part of the fertility picture. They should not be used alone to predict natural pregnancy with certainty.

This matters because test results can cause anxiety. A result is useful when interpreted in context by a qualified clinician. It should lead to clearer planning, not panic.

TCM assessment and fertility planning

At Olive3, your TCM assessment brings together your symptoms, menstrual history, everyday wellbeing and traditional patterns. Existing fertility reports provide additional context for planning your care and coordinating appointments.

A TCM consultation may include discussion of cycle patterns, sleep, digestion, stress, temperature sensations and general wellbeing. Depending on the individual, a registered TCM physician may discuss acupuncture, Chinese herbal medicine or lifestyle guidance from a TCM perspective.

In TCM, Kidney Jing (Essence) is a traditional concept associated with development and reproduction. Your physician may discuss this framework together with Qi (functional activity), Blood (nourishment), sleep and digestion when explaining the assessment. These are TCM concepts, distinct from the measurements in ovarian reserve tests.

Your plan is personalised to your assessment and preferences, with review points to discuss your response. If you are taking prescribed medication or receiving fertility treatment, discuss any changes with the prescribing clinician.

Good care is coordinated care. If a couple is seeing both a fertility specialist and a TCM physician, it is helpful to share relevant medication and treatment information so advice can be given safely.

Short FAQ

Should both partners be assessed?

Yes, where there is a male partner, both partners are usually considered. Fertility depends on egg, sperm, ovulation, tubes, uterus and timing. Testing only one person may miss useful information.

Does regular menstruation mean ovulation is definitely normal?

Regular cycles often suggest ovulation, but they do not prove everything is normal. If pregnancy has not happened after the recommended time frame, assessment may still be helpful.

Can AMH tell me whether I will conceive naturally?

No. AMH is mainly a marker of ovarian reserve and may help with treatment planning. It does not predict natural pregnancy with certainty.

Should I wait before seeking help if I am over 35?

If the female partner is 35 or older, assessment is commonly suggested after 6 months of trying. Earlier review may be suitable if there are symptoms or known medical concerns.

Can TCM be used during IVF or IUI?

TCM may be included in an individual care plan during IVF or IUI. Discuss suitability, medicines, herbs and procedure timing with your TCM physician and fertility clinician before starting.

Practical next steps

If pregnancy has not happened within the recommended timeframe, arrange fertility assessment. You can also meet Physician Koh to discuss your symptoms and explore an individual TCM plan; the appointments can be coordinated without delaying time-sensitive investigations.

For Singapore couples, a practical plan may look like this:

1. Note cycle dates, symptoms and how long you have been trying.

2. Gather previous test results, scans or semen analysis reports if any.

3. Discuss whether female and male evaluations are both needed.

4. Ask what each test can and cannot tell you.

5. Discuss how any TCM treatment and other care can be coordinated safely.
