WHEN PREGNANCY IS taking longer than expected, one of the first questions people ask is simple: why?
Fertility testing is designed to help answer that question. But a fertility assessment is not one blood test, one ultrasound or a single number that tells you whether you are fertile.
A complete fertility workup looks at several parts of reproduction together. For women, this can include ovulation, ovarian reserve, hormone levels, the uterus and fallopian tubes. For men, semen analysis and reproductive health are important parts of the picture. Medical history, age, previous pregnancies and other health factors can also influence which tests are useful.
This distinction matters because fertility rarely comes down to one result.
The purpose of fertility testing is to understand your reproductive health well enough to make informed decisions about what comes next. Depending on the results, that may mean continuing to try naturally, addressing an underlying issue, monitoring ovulation or discussing fertility treatments such as intrauterine insemination (IUI) or in vitro fertilization (IVF).
For Canadians considering fertility care, and particularly patients in Ontario, understanding what these tests actually measure can make the process much less confusing.
Many people assume they need to try for a full year before speaking with a fertility specialist. That is not always the case.
As a general clinical guideline, an infertility assessment is often considered after 12 months of regular, unprotected intercourse without pregnancy when the female partner is under 35. For women aged 35 and older, an assessment may be considered after about six months.
There are also situations where it makes sense to seek an evaluation sooner. These can include:
Age also matters. Female fertility changes over time, and the decline becomes more significant during the later reproductive years. Waiting an arbitrary number of months before seeking advice may therefore not make sense for every patient.
You also do not need an infertility diagnosis to have questions about your fertility. Someone considering egg freezing, donor-assisted reproduction or fertility preservation before medical treatment may have a fertility assessment for entirely different reasons.
The right time to seek testing depends on your circumstances, not simply how many months have passed.
Pregnancy requires several biological steps to work together.
An egg needs to develop and ovulation needs to occur. Sperm must be available and capable of reaching and fertilizing the egg. At least one functioning fallopian tube is generally needed for unassisted conception, and the uterus needs to provide an appropriate environment for implantation.
This is why there is no single test for infertility.
A female fertility assessment may investigate:
A male fertility assessment usually begins with medical and reproductive history and semen analysis, with further investigation when the initial findings suggest it is needed.
When a couple is trying to conceive using their own eggs and sperm, both partners should be considered as part of the fertility picture. Investigating one partner first and waiting months before evaluating the other can unnecessarily delay an infertility diagnosis and treatment plan.
For Ontario patients, Anova Fertility provides fertility assessment and treatment services that can help identify factors affecting conception and determine appropriate next steps.
Fertility tests for women typically combine medical history, bloodwork and imaging.
The exact tests you need will depend on factors including your age, menstrual cycle, medical history, previous pregnancies and the reason you are seeking fertility care.
1. Medical and Menstrual History
Some of the most useful information in a fertility assessment is collected before a blood sample is ever taken.
Your fertility specialist may ask about:
Your menstrual cycle can provide useful clues about ovulation.
Someone who consistently has predictable menstrual cycles may be ovulating regularly. Very long, short, irregular or absent cycles can suggest that ovulation needs to be investigated more closely.
Rather than ordering every available hormone test, a good fertility assessment uses your history to determine which tests are likely to provide meaningful information.
Health before pregnancy is also worth considering as part of the wider fertility picture. The Public Health Agency of Canada’s guidance on preconception health explains that health during the reproductive years can affect fertility as well as pregnancy and the health of a future child.
2. Ovulation Testing
Not every woman needs extensive testing to prove that ovulation is occurring.
For someone with regular and predictable menstrual cycles, the menstrual history itself can provide useful information.
When ovulation is uncertain, your fertility specialist may recommend additional investigation. Depending on the situation, this can include progesterone testing at an appropriate point in the menstrual cycle, ultrasound monitoring or other hormonal testing.
If periods are consistently irregular or absent, the more useful question may be why ovulation is not happening regularly.
Possible causes can include polycystic ovary syndrome (PCOS), thyroid disorders, changes in prolactin, hypothalamic dysfunction and other endocrine or reproductive conditions.
Identifying the underlying reason can be more valuable than simply confirming that ovulation did or did not occur during one particular month.
3. AMH Testing
Anti-Müllerian hormone, better known as AMH, has become one of the most widely discussed fertility blood tests.
AMH is produced by cells associated with developing follicles in the ovaries. Measuring it can provide information about ovarian reserve, which refers primarily to the quantity of eggs remaining in the ovaries.
AMH can be particularly useful when planning fertility treatment because it can help a fertility specialist estimate how the ovaries may respond to stimulation medications.
There is, however, an important distinction patients should understand:
AMH is not a pregnancy score.
It does not directly measure egg quality, nor can it tell you with certainty whether you will conceive naturally.
Two women can have similar AMH levels but very different fertility circumstances because age, reproductive history, sperm factors, fallopian tube health and other variables also matter.
Likewise, a lower AMH result does not automatically mean that natural pregnancy cannot occur.
AMH becomes much more useful when interpreted alongside age, antral follicle count, ultrasound findings and the rest of the fertility assessment.
4. FSH and Estradiol
Follicle-stimulating hormone, or FSH, is involved in stimulating follicle development within the ovaries.
FSH may be measured together with estradiol during the early part of the menstrual cycle, often around cycle days two to four.
The relationship between these hormones matters. An estradiol level that is already elevated early in the cycle, for example, can affect how an FSH result is interpreted.
This is another reason fertility blood tests should not be interpreted independently.
An FSH number downloaded from a laboratory portal provides only part of the story. Your age, AMH, ultrasound findings, cycle history and treatment goals provide the context needed to understand what that number actually means for you.
5. Thyroid and Other Hormonal Testing
Thyroid function can affect menstrual cycles and reproductive health, so thyroid-stimulating hormone, or TSH, may be included in a fertility workup.
Other hormone tests may be ordered when the patient’s symptoms or history suggest they would be useful.
This is an area where individualized fertility testing becomes important.
Ordering a very large hormone panel does not necessarily produce a better fertility assessment. Tests are most useful when there is a clinical reason for ordering them and a clear understanding of how the result could affect the next step.
6. Transvaginal Ultrasound
Bloodwork can tell your fertility team about hormones, but it cannot show the physical structure of your reproductive organs.
That is where ultrasound becomes valuable.
A transvaginal ultrasound may provide information about:
The results can also help put ovarian reserve blood tests into context.
For example, rather than making treatment decisions from AMH alone, your physician can compare the bloodwork with what is actually visible within the ovaries.
7. Antral Follicle Count
An antral follicle count, commonly called an AFC, is performed during a transvaginal ultrasound.
The clinician counts the small follicles visible within the ovaries. This provides another measure of ovarian reserve and can help estimate how the ovaries may respond during fertility treatment.
AMH and AFC answer similar questions, but they do so in different ways.
When the two are interpreted together, they can provide a more complete picture than either result alone.
The ultrasound also gives your fertility team information that cannot be obtained from bloodwork, including the physical appearance of the ovaries and uterus.
8. Checking the Uterine Cavity
The inside of the uterus is another important part of a fertility assessment.
A standard blood test cannot identify a polyp, certain fibroids or scar tissue inside the uterine cavity.
One method of investigating the cavity is a sonohysterogram, sometimes called saline infusion sonography.
During this procedure, sterile saline is introduced into the uterus while ultrasound is used to visualize the uterine cavity more clearly.
This part of the fertility workup answers a very different question from ovarian reserve testing. AMH provides information about the available egg pool, while uterine assessment examines the environment where an embryo would eventually need to implant.
9. Checking the Fallopian Tubes
The fallopian tubes provide the pathway where sperm and egg normally meet during unassisted conception.
If both tubes are blocked, that changes the fertility treatment conversation considerably.
Tubal patency can be evaluated using imaging procedures such as hysterosalpingography or ultrasound-based techniques. The appropriate test depends on the patient’s history and the fertility clinic’s protocol.
This is particularly important when natural conception or IUI is being considered because those approaches generally rely on at least one usable fallopian tube.
It is a good example of why fertility testing needs to look at the reproductive system as a whole. Normal ovarian reserve results cannot compensate for a mechanical barrier preventing sperm and egg from meeting.
Male fertility testing should not be treated as something to investigate only after every female test has been completed.
When sperm is part of the conception plan, evaluating male fertility early can save time and sometimes reveal an important part of the infertility diagnosis.
1. Semen Analysis
Semen analysis is the foundation of male fertility testing.
A semen analysis typically examines characteristics such as sperm concentration, motility and morphology. These measurements answer different questions.
Concentration looks at how many sperm are present within a given volume of semen.
Motility assesses how sperm move.
Morphology examines sperm shape and structure.
A sample can have an adequate sperm concentration but reduced movement. Another may show a lower concentration with relatively strong motility.
That is why a semen analysis should not simply be thought of as a pass-or-fail test.
Semen parameters can also vary from one sample to another. If an initial result is outside the expected range, your fertility specialist may recommend another sample or additional testing before reaching a conclusion.
2. Male Medical and Reproductive History
A semen analysis becomes much more informative when it is considered alongside medical history.
A fertility specialist may ask about:
One factor that deserves particular attention is external testosterone or anabolic steroid use.
Testosterone taken from outside the body can interfere with the hormonal signals involved in sperm production. Someone using prescribed testosterone or other hormones should therefore tell their fertility physician during the assessment.
Do not stop a prescribed medication without speaking to the healthcare professional managing your treatment.
3. When Are Additional Male Fertility Tests Needed?
Not every male patient needs an extensive hormone panel, genetic testing or specialized sperm testing.
Further investigation may be appropriate when sperm concentration is very low, no sperm are found in the sample, semen parameters are significantly abnormal or the medical history suggests a hormonal, anatomical or genetic issue.
Depending on the situation, additional evaluation might include hormone testing, physical examination, repeat semen analysis, genetic investigation or referral to another specialist.
The goal is targeted testing, not simply more testing.
One of the most useful things to know before having a fertility assessment is what the results cannot tell you.
There is no single fertility number that predicts your reproductive future.
AMH cannot tell you exactly how many years of fertility you have remaining.
A high AMH does not guarantee pregnancy.
A low AMH does not mean pregnancy is impossible.
A normal semen analysis cannot guarantee conception.
An abnormal semen analysis does not automatically mean pregnancy cannot occur.
And even when every standard fertility test appears reassuring, conception is never guaranteed.
This can be frustrating for patients who understandably want a definitive answer.
Fertility is influenced by multiple biological processes, and current testing can measure some of them much better than others.
The real value of a fertility assessment comes from putting the results together and asking what they mean for this particular patient or couple.
Sometimes a fertility workup does not identify an obvious problem.
Ovulation appears to be occurring. The uterus looks reassuring. The fallopian tubes are open. Ovarian reserve testing does not reveal an obvious concern. Semen parameters fall within expected ranges.
Yet pregnancy still has not occurred.
This can lead to a diagnosis of unexplained infertility.
The word “unexplained” can be misleading. It does not mean that there is no biological reason for the difficulty conceiving. It means the standard fertility assessment has not identified a specific cause that adequately explains it.
There are aspects of egg function, sperm function, fertilization, embryo development and implantation that routine testing cannot completely predict.
Treatment decisions can still be made.
Age, duration of infertility, previous pregnancies, test results and family-building goals can all help your fertility specialist determine whether continued trying, IUI, IVF or another approach makes sense.
More testing is not always better medicine.
This is particularly important in fertility care, where patients can encounter long lists of specialized tests online.
Some advanced investigations are valuable when a patient’s history or previous results provide a reason to perform them. That does not mean every patient needs them during an initial fertility workup.
Depending on the situation, your physician may decide that specialized genetic testing, advanced sperm investigations, additional uterine testing or other procedures are appropriate.
The important question is not simply, “Is this test available?”
A better question is:
“What would we do differently based on the result?”
If a test is unlikely to change the diagnosis or treatment plan, performing it automatically may provide little additional value.
The purpose of fertility testing is not simply to collect numbers. It is to make better decisions.
Your results may indicate that continuing to try naturally is reasonable.
Testing may identify an ovulation issue that can be treated or monitored.
A semen analysis may uncover a male factor that changes the recommended approach.
Tubal testing may identify a blockage that makes IUI less appropriate.
Ovarian reserve results may influence how urgently treatment is considered or how ovarian stimulation is planned.
In other cases, several relatively small findings may matter more when considered together.
This is why two people with the same AMH result can receive different recommendations.
Imagine a 29-year-old and a 40-year-old with similar ovarian reserve numbers. The laboratory result may look similar on paper, but age changes the clinical context substantially.
The same principle applies to male fertility.
A semen analysis should be interpreted alongside the female partner’s age, ovarian reserve, tubal status and the length of time the couple has been trying when those factors are relevant.
Fertility treatment should be based on the complete picture rather than a single result.
For patients in Ontario, there is an additional layer to fertility planning: understanding how fertility services fit within the provincial healthcare system.
Ontario operates a government-funded fertility program through participating clinics. To qualify for government-funded fertility treatment, patients must live in Ontario and have a valid Ontario health card. Additional eligibility requirements and coverage limits depend on the treatment being provided.
For IVF, the Ontario Fertility Program currently requires the patient to be under age 43 and provides funding for one treatment cycle per patient, subject to the program’s requirements. IUI and certain fertility preservation services are also included within the provincial program under their respective eligibility rules.
However, not every expense associated with fertility treatment is covered. Fertility medications, genetic testing and storage of sperm, eggs or embryos are among the costs excluded from Ontario Fertility Program coverage.
Patients considering treatment should review the current Government of Ontario fertility treatment and funding information before making assumptions about eligibility or costs.
This distinction is worth understanding before treatment begins.
Fertility testing, fertility treatment and fertility treatment funding are not the same thing.
Having a fertility assessment does not mean IVF will be recommended. Likewise, being medically eligible for treatment does not necessarily mean every associated expense will be publicly funded.
There may also be wait lists for publicly funded services, and participating clinics manage their own wait lists.
Coverage and program details can change, so patients should confirm current eligibility, availability and costs with their fertility clinic and the Government of Ontario.
A little preparation can make your initial appointment considerably more productive.
Before your appointment, gather information about:
If you have already undergone fertility testing at another clinic, contact Anova to confirm whether those records can be transferred before your first appointment.
This may prevent unnecessary duplication and gives your fertility specialist a better view of how results have changed over time.
Patients who have already completed fertility testing at another clinic should confirm with Anova which records can be submitted in advance of their first appointment.
For Ontario patients ready to understand their fertility more clearly, Anova Fertility provides fertility assessment and treatment services in Ontario.
An initial fertility assessment is about more than determining whether an individual result is “normal.”
It is an opportunity to understand how ovarian reserve, ovulation, reproductive anatomy, sperm health, age and medical history fit together, and what those findings mean for your individual path forward.
For patients who eventually require treatment, Ontario also offers publicly funded fertility services through participating clinics. Because eligibility and coverage depend on the treatment and individual circumstances, it is worth understanding both the medical recommendation and the funding options available before deciding on the next step.
When you receive your results, it can be tempting to focus immediately on numbers that appear high or low.
Instead, consider asking your fertility specialist:
These questions move the conversation beyond laboratory ranges and toward the information that actually matters: what should you do next?
Fertility testing is most valuable when it answers the right questions, not simply when more tests are ordered.
For women, a fertility workup may involve evaluating ovulation, ovarian reserve, hormones, the ovaries, uterus and fallopian tubes.
For men, semen analysis is an important starting point, with additional investigation guided by the results and medical history.
When two partners are involved, assessing both sides of the fertility picture early can prevent unnecessary delays.
Most importantly, no single fertility test should be viewed as a verdict on your ability to become a parent.
AMH, FSH, antral follicle count, ultrasound findings and semen parameters are pieces of a much larger picture. Their value comes from understanding how they relate to one another and to your age, medical history and family-building goals.
If you have been trying to conceive without success, have a known fertility risk factor or want a clearer understanding of your reproductive health before considering treatment, a comprehensive fertility assessment can give you something far more useful than a collection of test results: a clearer idea of what your next step should be.
