Signs of Infertility: When to See a Pollin Fertility Specialist

You've been trying. It hasn't worked yet. And now you're lying awake at 11pm wondering whether something is actually wrong or whether you just need to be more patient.

This is one of the most common places people get stuck; not because they don't suspect something might be off, but because they don't know what qualifies as a "real" concern versus normal variation. The internet gives you a hundred answers, most of them vague, many of them alarming, and almost none of them specific to your age, your body, or your situation.

This article gives you a clear framework. What the actual signs of infertility look like, when they warrant medical investigation, what testing involves, and how to take the first step in Ontario; without spending months wondering whether you're overreacting.

What "Infertility" Actually Means in Clinical Terms

Infertility is defined as the inability to conceive after 12 months of regular, unprotected intercourse for women under 35, or after 6 months for women 35 and older. The shorter timeline for patients over 35 reflects the clinical reality that ovarian reserve declines with age, and earlier investigation preserves more options.

This definition isn't a diagnosis. It's a threshold; the point at which medical investigation is recommended. Many people who meet this definition will conceive with treatment. Some will conceive without it. The definition exists to ensure patients aren't waiting longer than they should before getting answers.

If you haven't reached these timelines but have specific symptoms or risk factors (described below), earlier investigation may still be appropriate. Your doctor can help you decide.

Signs That May Indicate a Fertility Problem

In women

Irregular or absent periods: A menstrual cycle that varies significantly in length (shorter than 21 days or longer than 35 days), or periods that stop entirely, may indicate an ovulation disorder. Ovulation is required for natural conception. If your cycles are unpredictable, your body may not be ovulating consistently; or at all.

Very painful periods: Moderate cramping during menstruation is common. Severe pain that interferes with daily life; especially if accompanied by pain during intercourse, pain with bowel movements, or chronic pelvic pain, may indicate endometriosis, a condition in which tissue similar to the uterine lining grows outside the uterus. Endometriosis affects an estimated 10–15% of women of reproductive age and is a known cause of infertility.

Heavy or prolonged bleeding: Periods lasting longer than seven days, or bleeding that requires changing pads or tampons every hour, may signal uterine fibroids, polyps, or hormonal imbalances; all of which can affect fertility.

History of pelvic infections or sexually transmitted infections: STIs such as chlamydia and gonorrhea can cause pelvic inflammatory disease (PID), which may damage the fallopian tubes. Tubal damage is a significant cause of infertility and is often asymptomatic; meaning you may not know it's there without testing.

‍Known medical conditions: Polyendocrine metabolic ovarian syndrome (PMOS/formerly PCOS), thyroid disorders, premature ovarian insufficiency, and autoimmune conditions can all affect fertility. If you have a diagnosed condition that involves your hormones or reproductive system, earlier fertility evaluation is reasonable.

Two or more miscarriages: Recurrent pregnancy loss — defined as two or more clinical pregnancy losses — warrants investigation into potential underlying causes, including chromosomal factors, uterine abnormalities, and hormonal issues.

In men

Male factor contributes to approximately 40–50% of infertility cases in the broader population, yet it's often the last thing investigated. Signs that may indicate a male fertility issue include:

History of testicular injury, surgery, or undescended testes: Any prior testicular condition can affect sperm production or delivery.

‍Known hormonal issues: Low testosterone, thyroid disorders, or pituitary conditions can impact sperm production.

Difficulty with ejaculation or sexual function: Erectile dysfunction, retrograde ejaculation, or low libido may have underlying causes that also affect fertility.

Exposure to known risk factors: Certain medications, chemotherapy, radiation, excessive heat exposure, anabolic steroid use, heavy alcohol consumption, and smoking have all been associated with reduced sperm quality in the broader population.

No obvious signs at all: Many male fertility issues are subclinical — meaning there are no visible symptoms. A semen analysis is the most direct way to evaluate male fertility, and it's typically one of the first tests ordered.

Age as a Factor — What the Evidence Shows

Age is the single most significant variable in female fertility. This isn't a scare tactic; it's biology.

Under 30: Fertility is generally at its highest. Most patients in this age group who don't conceive within 12 months of trying have a specific, identifiable cause.

30–35: Fertility begins to decline gradually. The 12-month timeline before investigation remains standard, but patients with any risk factors should consider earlier evaluation.

‍35–37: The decline accelerates. Six months of trying is the recommended threshold before seeing a specialist. Ovarian reserve testing (AMH, antral follicle count) at this stage gives your doctor useful baseline data even before treatment is considered.

38–40: Each month matters more. Patients in this age group who are considering pregnancy should consult a fertility specialist early; ideally before they've been trying for six months. The evaluation itself takes time, and preserving options is the priority.

Over 40: A fertility evaluation before or at the time you begin trying is clinically appropriate. Egg quality and quantity both decline significantly, and earlier information supports better decision-making; whether that leads to treatment like IUI or IVF, or simply to a clearer understanding of your options.

These are population-level patterns. Individual variation is significant. Some patients at 40 have excellent ovarian reserve. Some patients at 30 have diminished reserve. Testing is what tells you where you actually stand.

When to See a Fertility Doctor — A Clear Decision Framework

See a specialist now if:

• You're under 35 and have been trying for 12 months without success
• You're 35 or older and have been trying for 6 months
• You have irregular, absent, or very painful periods
• You've had two or more miscarriages
• You have a diagnosed condition affecting your reproductive system (PCOS, endometriosis, thyroid disorder)
• Your partner has a known or suspected male factor issue
• You're over 38 and planning to start trying

Consider an evaluation even if you haven't started trying if:

• You want to understand your fertility baseline before making family planning decisions
• You're considering egg freezing or sperm freezing
• You have a family history of early menopause or premature ovarian insufficiency

You don't need to be in crisis to see a fertility specialist. A baseline evaluation; AMH, antral follicle count, and a conversation with a reproductive endocrinologist, gives you information. What you do with that information is your decision.

What the First Appointment Looks Like

A fertility evaluation typically involves:

‍For women:

• Blood tests to assess ovarian reserve (AMH — anti-Müllerian hormone) and hormone levels (FSH, LH, estradiol, thyroid, prolactin)
• A transvaginal ultrasound to count antral follicles and assess the uterus and ovaries
• Potentially a hysterosalpingogram (HSG) or saline sonogram to evaluate the fallopian tubes and uterine cavity

For men:

• A semen analysis; assessing count, motility, morphology, and volume
• Blood tests for hormonal evaluation
• Potentially a testicular ultrasound if there is history of a testicular issue or suspicion of a blockage

For both:

• A comprehensive review of medical history, lifestyle factors, and family planning goals
• A conversation with a specialist about what the results mean and what options look like

In Ontario, the initial fertility consultation is covered by OHIP. You need a physician referral to see a fertility specialist; but if you don't have one, some clinics arrange a referral for you through a partner clinic. It takes minutes, not weeks.

At Pollin, If you do not have a family doctor and require a referral to be facilitated for you, we will set you up with a virtual, OHIP-covered referral consultation with our partner GP after you have booked your consultation.

The Most Common Worry — and the Honest Answer

The question underneath everything is usually: “Am I infertile?”

The honest answer is that you won't know until you're tested. Symptoms and timelines create a reasonable basis for investigation, but the investigation is what gives you the answer, not the Googling.

Many patients who meet the clinical definition of infertility go on to conceive; some with treatment, some without. Many patients with no obvious symptoms discover an issue they didn't know about. The information itself is the value, regardless of which direction it points.

The hardest part is usually not the testing. It's making the appointment.

Frequently Asked Questions

What are the most common signs of infertility in women?

The most common indicators include irregular or absent periods, very painful periods (which may suggest endometriosis), a history of pelvic infections, known conditions like PMOS or thyroid disorders, and not conceiving after 12 months of trying (or 6 months if you're 35 or older).

Can you be infertile with no symptoms?

Yes. Many causes of infertility; including diminished ovarian reserve, tubal damage from asymptomatic infections, and male factor issues, have no visible symptoms. This is why testing is recommended after the appropriate time threshold, even if nothing seems wrong.

When should I see a fertility doctor?

If you're under 35 and have been trying for 12 months, or if you're 35 or older and have been trying for 6 months. See a specialist sooner if you have irregular periods, a history of miscarriage, a known reproductive condition, or if you're over 38 and planning to start trying.

How do I get a fertility evaluation in Ontario?

You need a physician referral to see a fertility specialist. Your family doctor or walk-in clinic doctor can provide one. Some fertility clinics also arrange a referral for you through a partner clinic if you don't have one; the process takes only a few minutes. The initial consultation is covered by OHIP.

At Pollin, If you do not have a family doctor and require a referral to be facilitated for you, we will set you up with a virtual, OHIP-covered referral consultation with our partner GP after you have booked your consultation.

Does age really affect fertility?

Yes. Age is the single most significant variable in female fertility, due to the decline in both egg quantity and quality over time. This is a population-level biological pattern; individual variation exists, and testing is the way to understand where you specifically stand.

What fertility tests should I ask about?

For women: AMH (ovarian reserve), FSH, LH, estradiol, thyroid function, antral follicle count (ultrasound), and potentially a tubal assessment (HSG). For men: a semen analysis and blood tests. These tests give your specialist the information needed to assess your situation and discuss options.
