Infertility Evaluation: Tests, Causes and Fertility Assessment

Infertility evaluation is a systematic assessment that helps identify factors affecting the ability to conceive. It may involve assessment of ovulation, the uterus and fallopian tubes, sperm health, medical history, and other factors relevant to an individual or couple.

Understanding the cause—or recognising when no clear cause is identified—helps guide discussions about appropriate next steps and possible treatment options.

What Is Infertility?

The World Health Organization defines infertility as a disease of the male or female reproductive system characterised by failure to achieve a pregnancy after 12 months or more of regular, unprotected sexual intercourse.

Infertility may be related to male factors, female factors, a combination of factors, or remain unexplained after evaluation. A fertility assessment can also be appropriate earlier when there are known risk factors or when reproductive assistance is needed for other reasons.

Infertility is a medical issue affecting individuals and couples. Assessment should be respectful, confidential, and tailored to the person’s circumstances and reproductive goals.

When Should You Seek an Infertility Evaluation?

Under 35 years

Evaluation is generally recommended after 12 months of regular, unprotected intercourse without conception, if there are no known risk factors.

Age 35 years or older

Evaluation is generally recommended after 6 months without conception. Earlier assessment may be appropriate depending on history.

Over 40 years

More immediate evaluation and discussion of treatment options may be warranted.

Known risk factors

Seek assessment without delay when there are irregular or absent periods, suspected tubal or uterine disease, endometriosis, known male-factor concerns, sexual dysfunction, or a history of fertility-threatening treatment.

These are general timing recommendations. A clinician may recommend earlier evaluation based on medical history, symptoms, age, or prior investigations.

Common Causes of Infertility

Female-related factors

  • Ovulatory disorders: Irregular or absent ovulation, including ovulatory dysfunction associated with polycystic ovary syndrome (PCOS) or other endocrine conditions.
  • Tubal factors: Blocked or damaged fallopian tubes, sometimes associated with prior infection, pelvic inflammatory disease, surgery, or other conditions.
  • Uterine factors: Conditions such as certain fibroids, congenital uterine differences, or intrauterine abnormalities that may affect reproductive outcomes.
  • Endometriosis: May be associated with pelvic inflammation, adhesions, pain, and reduced fertility in some patients.
  • Age-related changes: Increasing age can affect egg number, egg quality, and reproductive outcomes.
  • Endocrine conditions: Thyroid disorders and other hormonal disturbances may affect menstrual function or ovulation.

Male-related factors

  • Low sperm concentration or absence of sperm in the ejaculate.
  • Reduced sperm motility or abnormal sperm morphology.
  • Obstruction affecting sperm transport or ejaculation.
  • Hormonal disorders or impaired sperm production.
  • Sexual or ejaculatory dysfunction, certain medicines, or prior medical treatments.

Combined or unexplained infertility

More than one contributing factor may be present. In some people, standard evaluation does not identify a specific explanation; this may be described as unexplained infertility after appropriate assessment.

What Happens During the First Fertility Consultation?

The first appointment typically involves a detailed discussion of reproductive goals and relevant medical history. Both partners should be included in assessment when applicable, rather than assuming the cause lies with one person.

  • Duration of attempts to conceive and prior pregnancies.
  • Menstrual pattern, cycle regularity, bleeding, and pelvic symptoms.
  • Previous fertility treatment, pregnancy loss, or reproductive surgery.
  • Medical conditions, infections, medications, and relevant family history.
  • Sexual health, intercourse or insemination timing, and any difficulties.
  • Lifestyle and occupational factors that may be relevant to reproductive health.
  • Prior test results and the patient’s preferences, concerns, and treatment goals.

A physical examination may be performed when indicated. The evaluation should be targeted to the person’s history and clinical needs.

Female Infertility Evaluation: Common Investigations

1. Ovulation assessment

Menstrual history is an important starting point. Regular cycles, commonly in the range of 21–35 days, are often consistent with ovulation. Additional testing may be appropriate when cycles are irregular, symptoms suggest an endocrine disorder, or the clinical picture is uncertain.

Depending on the circumstances, a clinician may consider ovulation predictor kits, appropriately timed progesterone testing, or ultrasound monitoring.

2. Pelvic ultrasound

Transvaginal ultrasound can assess the uterus, endometrium, ovaries, and visible pelvic structures. It may help identify fibroids, ovarian cysts, features of PCOS, or other findings that require further evaluation.

3. Ovarian reserve assessment

Tests such as anti-Müllerian hormone (AMH), antral follicle count (AFC), and selected hormone measurements may be used to help estimate ovarian response to fertility medication and guide treatment planning.

Important: Ovarian reserve tests do not independently determine whether a person can conceive naturally, and they should be interpreted alongside age, history, and other findings.

4. Tubal patency

Hysterosalpingography (HSG) or other appropriate imaging tests may be used to assess whether the fallopian tubes are open. The choice of test depends on history, local practice, and clinical indications.

5. Uterine cavity assessment

Ultrasound, saline infusion sonography, or hysteroscopy may be considered when the history or initial imaging suggests a uterine cavity abnormality. Not every patient needs every procedure.

6. Hormonal tests

Testing may include thyroid-stimulating hormone (TSH) or other targeted hormone tests when indicated. Prolactin, androgen testing, and additional investigations are generally selected according to symptoms and clinical findings rather than ordered indiscriminately for everyone.

Male Infertility Evaluation

Male-factor assessment should begin in parallel with female assessment when a male partner contributes sperm. A semen analysis is a key initial investigation and provides information about several characteristics of the ejaculate.

Semen analysis may assess:

  • Semen volume and other sample characteristics.
  • Sperm concentration and total sperm number.
  • Sperm motility.
  • Sperm morphology, according to laboratory criteria.

Results can vary between samples. A clinician may recommend repeat testing or referral to a reproductive urologist or andrologist depending on the findings.

Additional tests when indicated

  • Focused medical, reproductive, medication, and surgical history.
  • Physical examination, including assessment for relevant genital or endocrine findings.
  • Hormonal testing when sperm abnormalities or symptoms suggest an endocrine cause.
  • Genetic testing or imaging in selected cases, based on the clinical presentation.
  • Assessment of sexual or ejaculatory dysfunction where relevant.
Advanced sperm-function tests and other specialised investigations are not routinely required for every initial infertility assessment. Their use should be guided by the clinical situation.

What Tests Are Not Routinely Needed for Everyone?

Broad testing without a clinical indication can add cost, delay, and uncertainty. Depending on the circumstances, the following are generally not part of every routine initial evaluation:

  • Laparoscopy for unexplained infertility without a specific indication.
  • Advanced sperm-function testing, including sperm DNA fragmentation testing, as a universal first-line test.
  • Postcoital testing.
  • Thrombophilia or immunologic testing without a relevant indication.
  • Endometrial biopsy solely as a routine infertility test.
  • Prolactin, progesterone, and other reproductive hormone tests when there is no clinical reason to order them.

The treating clinician may still recommend one of these investigations when symptoms, history, or prior results make it appropriate.

What Happens After the Evaluation?

After reviewing the history and test results, the fertility team discusses the findings and possible next steps. Depending on the cause, options may include:

  • Timed intercourse or ovulation tracking when appropriate.
  • Ovulation induction for selected ovulatory disorders.
  • Surgery or other treatment for specific tubal, uterine, or pelvic conditions when indicated.
  • Intrauterine insemination (IUI) in selected circumstances.
  • In vitro fertilisation (IVF), with or without intracytoplasmic sperm injection (ICSI), when clinically appropriate.
  • Further male-factor assessment or treatment.
  • Donor gametes or other family-building pathways, where appropriate and in accordance with applicable rules and consent.
  • Additional counselling or review when the evaluation does not identify a clear cause.

The treatment plan should reflect the diagnosis, age, duration of infertility, previous treatment, medical considerations, personal preferences, and expected benefits and limitations.

30 Frequently Asked Questions About Infertility Evaluation

1. What is an infertility evaluation?

It is a structured medical assessment to identify factors that may be affecting conception. It commonly includes reproductive history, assessment of ovulation and reproductive anatomy, and semen analysis when applicable.

2. When is infertility diagnosed?

Infertility is commonly defined as failure to achieve pregnancy after 12 months or more of regular, unprotected intercourse. Evaluation may be appropriate earlier depending on age, history, symptoms, or reproductive circumstances.

3. Should both partners be evaluated?

Yes, when both partners are contributing to conception, assessment should generally occur in parallel. This helps avoid unnecessary delays and recognises that factors may be male-related, female-related, combined, or unexplained.

4. At what age should a woman seek evaluation?

In the absence of known risk factors, evaluation is generally considered after 12 months of trying under age 35, after 6 months at age 35 or older, and more promptly for those over 40. Individual circumstances may change this timing.

5. Can I seek help before trying for 12 months?

Yes. Earlier consultation may be appropriate with irregular or absent periods, known reproductive conditions, prior gonadotoxic treatment, suspected male-factor infertility, sexual dysfunction, or other relevant concerns.

6. What happens at the first appointment?

The clinician reviews medical and reproductive history, menstrual patterns, prior pregnancies and treatments, medications, symptoms, and relevant lifestyle or family history. Examination and tests are selected according to the findings.

7. Is infertility evaluation painful?

Many parts, such as history-taking, blood tests, ultrasound, and semen analysis, are not usually painful, although experiences vary. Some procedures, including HSG, can cause temporary cramping or discomfort. Ask your clinic what to expect.

8. What is a semen analysis?

It is a laboratory test that examines semen characteristics and sperm parameters such as concentration, motility, and morphology. It is a key initial test in male-factor evaluation.

9. Does an abnormal semen analysis mean infertility is permanent?

No. Results need to be interpreted in context and may vary between samples. Further testing, repeat analysis, or specialist review may be recommended based on the pattern of abnormalities.

10. What is AMH testing?

Anti-Müllerian hormone is a blood test that can contribute to assessment of ovarian reserve and help guide ovarian stimulation planning. It does not independently predict whether natural conception will occur.

11. What does an antral follicle count show?

AFC is an ultrasound-based count of small follicles in the ovaries. It can help estimate ovarian response to stimulation and is interpreted alongside age, AMH, and the broader clinical picture.

12. Can AMH tell me whether I can get pregnant naturally?

AMH is not a standalone test of natural fertility. It is one component of assessment and should not be used in isolation to determine whether pregnancy is possible.

13. What is HSG?

Hysterosalpingography is an imaging test that uses contrast and X-rays to assess the uterine cavity and whether the fallopian tubes appear open. Your clinician will explain preparation, timing, risks, and alternatives.

14. Is HSG necessary for every patient?

No. Tubal testing is selected according to medical history, risk factors, and the planned treatment. A clinician can explain whether HSG or another test is appropriate.

15. What does a pelvic ultrasound evaluate?

It can assess the uterus, endometrium, ovaries, and selected pelvic structures. It may identify findings that need further assessment, but not every cause of infertility can be diagnosed by ultrasound alone.

16. How is ovulation assessed?

Menstrual history is often the starting point. When needed, assessment may include ovulation predictor kits, appropriately timed progesterone measurement, or ultrasound monitoring.

17. Do regular periods mean I am definitely ovulating?

Regular cycles are often consistent with ovulation, but history is interpreted in context. Additional testing may be considered when symptoms or clinical findings raise a concern.

18. Which hormone tests may be requested?

Tests are tailored to the clinical picture. TSH may be considered for thyroid assessment, while prolactin, androgens, FSH, estradiol, or other tests may be used when specific symptoms or findings indicate them.

19. Is prolactin testing required for everyone?

Not usually. It may be indicated with symptoms or findings such as galactorrhea, amenorrhea, or oligomenorrhea, or when the clinician otherwise suspects a prolactin-related disorder.

20. Can PCOS cause infertility?

PCOS can be associated with irregular ovulation and difficulty conceiving. Assessment considers menstrual history, symptoms, examination, and appropriate investigations; management depends on individual needs.

21. Can blocked fallopian tubes cause infertility?

Yes. Tubal obstruction or damage can interfere with the meeting of egg and sperm or affect reproductive outcomes. Testing and treatment depend on the location and extent of the problem.

22. Can endometriosis affect fertility?

Endometriosis may be associated with reduced fertility in some patients. The significance depends on symptoms, disease extent, age, ovarian reserve, and other factors.

23. What is unexplained infertility?

It is a term used when standard evaluation does not identify a specific cause. It does not mean that the difficulty is imaginary; it means available routine tests have not revealed a clear explanation.

24. Are genetic tests always required?

No. Genetic testing is generally selected for specific indications, such as certain severe sperm abnormalities, relevant family history, or other clinical findings. A specialist can explain when it may be useful.

25. Are sperm DNA fragmentation tests routine?

They are not generally recommended as a universal first-line test for every infertility evaluation. A clinician may consider specialised testing in selected circumstances.

26. Does lifestyle affect fertility?

Factors such as smoking, excessive alcohol intake, obesity, some medications, and certain exposures have been associated with reproductive effects. Discuss practical, evidence-based changes with your clinician without assuming lifestyle is the sole cause.

27. Can infertility be treated?

Many causes have management options, but the appropriate approach and expected outcomes vary. Treatment may involve addressing an underlying condition, fertility medicines, surgery in selected cases, IUI, IVF, or other options.

28. Will I need IVF after evaluation?

Not necessarily. IVF is one of several possible treatments. Recommendations depend on the findings, age, duration of infertility, previous treatment, and personal preferences.

29. How long does the evaluation take?

The timeline varies with cycle timing, appointment availability, investigations, and whether additional assessment is needed. Your clinic can outline the likely sequence and timing for your situation.

30. What should I bring to my fertility appointment?

Bring previous investigation reports, treatment records, a medication list, relevant medical or surgical history, and details of menstrual cycles or prior pregnancies where applicable. Write down your questions and concerns so they can be discussed.
