Fertility FAQ: Answers to Common
Questions About Getting Pregnant

Most couples having regular unprotected sex conceive within a year, and a large proportion within the first six months. Taking several months is normal and does not by itself indicate a fertility problem.

Conception is probabilistic rather than guaranteed. Even for a couple with no fertility problems, the chance in any single cycle is modest, which is why the numbers accumulate over months rather than arriving immediately.

Age changes the timeline. Conception generally takes longer as female age increases, and the chance per cycle declines, which is why the advice about when to seek help differs by age rather than being a single rule for everyone.

What matters more than the raw number of months is whether anything is known to be different in your situation: irregular cycles, a known condition, previous pelvic surgery, or a partner with a known issue. Those shorten the sensible waiting period considerably.

Intercourse every one to two days across the fertile window gives the best chance for most couples, without requiring you to predict ovulation precisely.

Sperm can survive several days in the female reproductive tract, while the egg is viable for a much shorter period after ovulation. This means having sperm already present before ovulation is generally more effective than waiting until you are certain ovulation has happened.

Two common mistakes work against couples. Saving up by abstaining for a week rarely helps, and it often means missing the window entirely. Targeting one predicted day leaves no margin if ovulation shifts, which it frequently does.

If tracking is becoming stressful, regular intercourse two to three times per week through the cycle covers the fertile window reasonably well without any tracking at all.

Ovulation can be identified by combining several signs rather than relying on one. Cycle pattern, cervical mucus, basal body temperature and LH testing each tell you something different, and no single one is perfect.

• Cycle pattern is suggestive but does not confirm ovulation occurred
• Cervical mucus becomes clear and slippery as estrogen rises before ovulation
• LH tests predict that ovulation may be approaching, but do not confirm it happened
• Basal body temperature rises after ovulation, so it confirms rather than predicts
• Progesterone testing in the luteal phase provides clinical evidence that ovulation occurred

Apps predict from dates. They do not observe your body, so a calendar prediction should never be treated as confirmation.

If your cycles are irregular, or you have PCOS or PMOS, interpretation becomes harder and LH tests in particular can be misleading.

Go deeper: How PMOS affects ovulation and tracking →

The fertile window is roughly six days: the five days before ovulation plus the day of ovulation itself. The highest chance is generally in the two to three days immediately before ovulation.

The length comes from sperm survival rather than egg survival. Sperm can remain capable of fertilization for several days in favourable conditions, while the egg has a much shorter window after release.

This is why the practical advice is to cover the days leading up to ovulation rather than aiming at the day itself. By the time an LH test turns positive, you are already inside the window and should not wait.

Cycle length varies for most women, so the window moves. Assuming ovulation always falls on day 14 is one of the most common reasons couples miss it.

Seek evaluation after 12 months of trying if you are under 35, and after 6 months if you are 35 or older. Several situations justify going sooner, and waiting out the standard timeline is not always the right choice.

Go earlier if any of these apply:

• irregular, very long or absent periods
• a known condition such as PCOS or PMOS, endometriosis or thyroid disease
• previous pelvic surgery or a known tubal problem
• previous chemotherapy or radiation
• two or more miscarriages
• a known male factor, or previous testosterone or anabolic steroid use
• age over 40, where evaluation should not be delayed

Evaluation is not a commitment to treatment. It usually means a semen analysis, an assessment of ovulation, ovarian reserve testing and a check of tubal status. Those results either reassure you that continuing is reasonable, or reveal something that changes the plan.

The most common and most costly mistake is waiting. Reproductive time is the one variable that never moves in your favour.

Go deeper: Start with the free fertility assessment →

Initial female evaluation usually covers whether you are ovulating, what your ovarian reserve looks like, whether your fallopian tubes are open, and whether the uterus appears normal. Additional testing follows from those findings rather than being ordered all at once.

• Ovulation, often through a luteal-phase progesterone test timed to your cycle
• Ovarian reserve, usually AMH and an antral follicle count
• Tubal patency, using an appropriate imaging test
• Pelvic ultrasound to assess the uterus and ovaries
• Thyroid function and prolactin where clinically indicated
• Further testing based on symptoms, history and initial findings

A useful principle before any test: would an abnormal result change what we do next? If the answer is no, the test mostly adds cost and anxiety.

Testing should also run in parallel with your partner's evaluation, not after it.

Male evaluation begins with a medical and reproductive history and a semen analysis. Hormonal, genetic and specialised sperm testing are used selectively, based on those first findings.

A semen analysis reports volume, sperm concentration, total sperm number, motility, progressive motility and morphology. It should be interpreted as a whole rather than by one highlighted number, and parameters vary between samples, so a single abnormal result often warrants a repeat.

Two things are frequently missed. Testosterone or anabolic steroid use can suppress sperm production severely, so it must be disclosed. And normal sexual function tells you nothing about sperm production, so feeling well is not reassurance.

Male factors contribute to roughly half of infertility cases, which is why testing the man last is one of the most common ways couples lose time.

AMH is a marker of ovarian reserve, meaning roughly how many follicles remain and how your ovaries are likely to respond to stimulation. It does not measure egg quality, and it cannot tell you whether you will conceive.

A low AMH means fewer eggs, not worse eggs. A 30 year old with low AMH still has 30 year old eggs, and age remains the strongest predictor of whether an egg is chromosomally competent.

High AMH is not a fertility score either. Women with PMOS often have high AMH because they have more small follicles, alongside irregular ovulation.

Where AMH genuinely matters is planning: it informs your reproductive timeline and what to expect from treatment, which is a reason to seek advice earlier rather than to despair.

Go deeper: What a low AMH result actually means →

Ovarian reserve is usually assessed with AMH and an antral follicle count on ultrasound, interpreted alongside your age. FSH and estradiol are sometimes used in specific contexts.

These markers estimate quantity and likely response to stimulation. None of them counts your remaining eggs, and none of them assesses whether those eggs are chromosomally normal.

Timing and interpretation matter. Hormonal contraception can affect results, and a single measurement taken shortly after ovarian surgery will look worse than the true position.

If ovarian surgery is being proposed, particularly for an endometrioma, ask for ovarian reserve to be measured before you agree to it, so you know what you are trading.

Go deeper: Ovarian reserve, AMH and what the numbers mean →

A semen analysis measures semen volume, sperm concentration, total sperm number, motility, progressive motility and morphology, along with other laboratory observations.

Widely used WHO lower reference values are approximately 16 million sperm per mL, 39 million total per ejaculate, 42 percent total motility, 30 percent progressive motility and 4 percent normal morphology. These are reference points, not a line separating fertile from infertile.

Morphology is the most misread number on the report. Under strict criteria the percentage classified as normal is low even in fertile men, so a result of 2 or 3 percent does not mean 97 percent of your fertility is gone.

Results vary between samples and can be affected by recent illness, fever, abstinence interval and collection problems, so one abnormal result is a reason to repeat and investigate, not a verdict.

Some aspects of fertility can genuinely be improved, particularly where a modifiable factor is present. But nothing reverses reproductive aging, and no protocol can guarantee conception.

Changes with reasonable evidence behind them include stopping smoking, addressing heavy alcohol use, improving metabolic health where it is impaired, correcting documented nutritional deficiencies, treating conditions such as thyroid disease, and improving ovulation where it is irregular.

What cannot be done is equally important to state plainly. You cannot make eggs biologically younger, guarantee a chromosomally normal embryo, or reverse ovarian aging through diet, supplements or detoxification.

Natural optimisation and medical care are not opposing choices. The problem is not working on your health. The problem is spending a year on protocols while the tests that would actually direct your plan go undone.

Go deeper: Find out which factors are relevant to you →

Preconception preparation is mostly unglamorous and well evidenced: folic acid, reviewing medications, managing existing conditions, and addressing smoking and heavy alcohol use. Both partners are involved.

• start appropriate folic acid before conception
• review prescription medicines, over-the-counter products and herbal supplements with a clinician
• review management of conditions such as thyroid disease, diabetes, hypertension, PCOS or PMOS
• stop smoking, and reduce heavy alcohol intake
• check vaccinations and any relevant screening
• correct documented nutritional deficiencies rather than supplementing blindly
• the male partner should address smoking, alcohol, and any testosterone or steroid use

If you are over 35, or have a known condition, it is reasonable to arrange baseline evaluation early rather than waiting to see what happens.

You do not need to reach a perfect state of health before you are allowed to try. Preparation should run alongside trying, not instead of it.

Diet supports reproductive and metabolic health and may improve outcomes where nutrition is poor or metabolic health is impaired. But no diet has been proven to treat infertility, and no food changes the chromosomal competence of an egg.

Dietary patterns richer in vegetables, fruits, whole grains, legumes, nuts, fish and unsaturated fats have been associated with better reproductive outcomes in observational research. Association is not proof that a particular diet is a treatment.

Be sceptical of anything requiring you to eliminate several food groups without a clinical reason. Restriction carries real costs: nutritional inadequacy, social isolation and anxiety around food, all of which get worse the longer they continue.

Nutrition matters most where there is something to correct: a deficiency, poor metabolic health, or a diet that is genuinely inadequate.

Go deeper: How metabolic health affects fertility →

Body weight can affect fertility at both extremes. Obesity and metabolic dysfunction can disrupt ovulation and hormonal signalling, and very low body weight or low energy availability can do the same.

Where excess weight and metabolic dysfunction are present, sustainable improvement can restore more regular ovulation and support pregnancy health. That is a real and worthwhile effect.

But weight is not a universal prescription. Many women with PCOS or PMOS are lean, endometriosis occurs across all body sizes, and telling a lean woman to lose weight helps nothing while delaying evaluation.

Timing matters too. For a woman approaching 40, spending a year pursuing a target weight before any fertility evaluation is usually the wrong trade. Weight management and fertility care can run in parallel.

Go deeper: Weight, metabolic health and fertility →

They matter for your overall health and wellbeing, and chronic problems are worth addressing. But the evidence that everyday stress or occasional poor sleep directly causes infertility is much weaker than fertility content implies.

Regular physical activity supports insulin sensitivity, cardiovascular health, body composition, sleep and mood. Extreme training with inadequate fuelling can suppress ovulation, so more is not automatically better.

Stress deserves care rather than blame. Infertility is itself a major stressor, and telling someone their stress is preventing pregnancy adds guilt without providing a solution.

A useful test of priorities: if you are worrying about one late night while smoking daily or leaving a known condition unmanaged, the priorities are the wrong way round.

Go deeper: How lifestyle interacts with reproductive hormones →

Ovulation is necessary for conception but not sufficient. Pregnancy also requires open and functional fallopian tubes, adequate sperm, fertilization, a competent embryo and successful implantation.

If you are ovulating regularly and still not conceiving, the factors most worth checking are tubal patency, your partner's semen analysis, your age and how long you have been trying, and whether a condition such as endometriosis may be present.

Age is often the missing part of the explanation. Regular ovulation at 39 does not carry the same chance per cycle as regular ovulation at 29, because embryo chromosomal competence changes with age.

Confirming ovulation is a good first step. Treating it as the whole answer is where couples lose months.

Go deeper: Check the rest of the picture, for both partners →

Yes. Standard fertility testing cannot observe every step of reproduction, so a couple can have entirely normal results and still not conceive. This is common and it does not mean the tests were pointless.

Testing can confirm that you ovulate, that tubes appear open, that the uterus looks normal and that semen parameters fall within reference ranges. It cannot directly assess fertilization, embryo competence, implantation or many of the interactions between them.

Normal results are still useful. They rule out several treatable causes and they change what your realistic options are.

Where results are normal and time is limited, particularly with advancing age, the conversation usually shifts from finding a cause to choosing the approach with the best chance within the time available.

Go deeper: When treatment does not work as expected →

Unexplained infertility means no cause has been identified after standard evaluation. It is a description of what testing found, not a statement that nothing is wrong or that pregnancy cannot happen.

It is a common diagnosis, and it can be deeply frustrating precisely because there is nothing obvious to fix. But it should not be read as a dead end, and many couples with this label do conceive.

Two responses are worth avoiding. One is accepting it passively without considering age and time. The other is pursuing unvalidated tests and treatments, which is exactly the situation these couples are most often marketed to.

Before paying for any additional investigation, ask the same question that applies everywhere: if this result is abnormal, would it change management using a treatment supported by good evidence?

Go deeper: Reviewing what has and has not been assessed →

Yes. Difficulty conceiving after a previous pregnancy is called secondary infertility, and it is more common than most people expect. A previous child does not guarantee that conception will happen as easily again.

Things change between pregnancies. You are older, ovarian reserve has declined, a condition such as endometriosis may have progressed, pelvic or uterine surgery may have occurred, weight and metabolic health may have shifted, and your partner's semen parameters may have changed too.

Secondary infertility is often taken less seriously, both by couples and sometimes clinically, because a previous pregnancy feels like proof that everything works. The same evaluation timelines apply.

If you are 35 or older and have been trying for six months, that warrants evaluation regardless of how straightforward your first pregnancy was.

Go deeper: The same evaluation applies the second time →

There is no single answer, because the right amount of time depends on your age, what is already known about your fertility, and how long you have already been trying.

Under 35 with no known problems, 12 months is a reasonable point to seek evaluation. At 35 and over, 6 months. Over 40, or with a known condition, sooner still.

What should shorten that window: irregular ovulation, a known condition, previous pelvic surgery, reduced ovarian reserve, an abnormal semen analysis, or two or more miscarriages.

Continuing to try naturally and getting evaluated are not mutually exclusive. You can keep trying while the tests are arranged, and for most couples that is the sensible combination.

Go deeper: Work out the right timeline for your situation →

Yes, most often by disrupting ovulation. Irregular or absent ovulation reduces the number of opportunities to conceive each year, rather than meaning conception is impossible.

PCOS was renamed PMOS, or Polyendocrine Metabolic Ovarian Syndrome, in 2026. It is the same condition, and the new name reflects that it involves hormonal and metabolic processes rather than being defined by ovarian cysts.

Many women with PMOS conceive, particularly once ovulation is occurring more predictably. Treatment usually focuses on ovulation and relevant metabolic health rather than on trying to reverse the diagnosis.

Low AMH usually indicates reduced ovarian reserve, but it does not by itself mean natural pregnancy is impossible or that the remaining eggs are poor quality. Age and other fertility factors also matter.

If you are ovulating, low AMH does not prevent conception. What it does change is your reproductive timeline and what to expect from treatment, particularly the number of eggs likely to be retrieved in IVF.

The most common error is treating low AMH as a diagnosis of poor egg quality. They are different measurements, and confusing them leads to the wrong plan.

Go deeper: Explore the complete Low AMH FAQ →

Age-related changes in egg competence do reduce the chance of conception and increase miscarriage risk. But there is no routine test that measures egg quality, so the label is often applied without evidence.

Before accepting it, ask what it was based on. Low AMH, a miscarriage, unexplained infertility and one disappointing IVF cycle are not interchangeable, and none of them diagnoses poor egg quality on its own.

What can be optimised is genuine but limited: nutrition, metabolic health, smoking, deficiencies and existing conditions. What cannot be done is reversing reproductive aging.

Yes. Male factors contribute to roughly half of infertility cases, and a man can have completely normal sexual function alongside an abnormal semen analysis.

A semen analysis is quick, inexpensive and should be one of the first tests a couple does, not the last. Many couples spend months investigating the woman before the man is tested at all.

Some male factors are genuinely treatable, including suppression from testosterone or anabolic steroids, infection, and a clinically significant varicocele in selected men.

Endometriosis is associated with reduced fertility, but many women with it conceive naturally. The diagnosis alone does not predict your outcome.

It can affect fertility through several pathways: distorted pelvic anatomy, adhesions, tubal damage, reduced ovarian reserve where endometriomas or ovarian surgery are involved, inflammation, and pain that limits intercourse. Which pathway applies to you determines the plan.

One decision matters more than most: ovarian surgery for an endometrioma reduces ovarian reserve, so reserve should be measured before you agree to it.

Most early miscarriages happen because the embryo had a chromosomal abnormality that prevented normal development. These usually occur sporadically and could not have been predicted or prevented.

Miscarriage is common, affecting roughly 10 to 20 percent of recognised pregnancies. Everyday activities such as exercise, working, sex, travel and stress are not typical causes.

After repeated losses the situation changes, and a structured evaluation becomes appropriate, covering uterine anatomy, antiphospholipid syndrome, genetic factors, relevant medical conditions and both partners.

Go deeper: Explore the complete Miscarriage FAQ →

Investigate before repeating. A failed cycle contains information about which stage struggled, and repeating the same protocol without understanding why it failed often produces the same outcome.

The useful question is not simply whether the embryos were good. It is where the cycle ran into difficulty: ovarian response, egg maturity, fertilization, embryo development or implantation. Each points somewhere different.

Both partners belong in that review. Sperm contributes half of embryo development, and sperm factors are frequently overlooked after an unsuccessful cycle.

See a specialist after 12 months of trying under 35, after 6 months at 35 or over, and sooner if anything specific is already known about your situation.

Go promptly rather than waiting if you have irregular or absent periods, a known condition such as endometriosis or PMOS, previous pelvic surgery, two or more miscarriages, a known male factor, or you are over 40.

A first appointment is usually assessment rather than treatment: history for both partners, ovulation, ovarian reserve, tubal status and a semen analysis.

Seeing a specialist does not commit you to IVF. It gives you the information needed to decide between continuing naturally, simpler treatment, or assisted reproduction.

Go deeper: What fertility treatment involves →

IUI is generally considered when ovulation is occurring or can be induced, at least one fallopian tube is open, and semen parameters are adequate. It is a simpler and less invasive step than IVF.

It is more likely to be appropriate with mild male factor findings, unexplained infertility in a younger woman, ovulatory problems being treated with medication, or where intercourse is difficult.

It is less likely to be the right choice when tubes are blocked, the male factor is significant, ovarian reserve is very low, or age means several unsuccessful cycles would consume time you cannot spare.

Success rates per cycle are modest, so the number of attempts before moving on should be agreed in advance rather than drifting.

Go deeper: Comparing IUI, IVF and ICSI →

IVF is considered when tubes are blocked or damaged, when the male factor is significant, when ovarian reserve or age make time critical, when simpler treatments have not worked, or when a specific clinical reason makes it the most direct route.

IVF bypasses several barriers rather than curing an underlying condition. That is precisely why it works well for tubal factors and for many women with endometriosis, and why the condition itself remains after treatment.

It is not automatically required because you have a diagnosis. Many women with PMOS, endometriosis or low AMH conceive without it.

Where it is the right route, delaying has a cost too. The aim is to choose the approach with the best chance within the reproductive time available, not to avoid treatment on principle.

Go deeper: How treatment decisions are made →

Yes. Natural conception after unsuccessful treatment, and after a successful cycle, does happen. A failed cycle does not mean your fertility has been used up.

Sometimes treatment reveals a factor that can then be addressed, and sometimes conditions simply change: metabolic health improves, a male factor is corrected, or ovulation becomes more regular.

This should not be turned into a reason to avoid treatment or to keep waiting indefinitely, particularly where age or ovarian reserve makes time limited.

The realistic position is that both routes remain open, and the right one depends on your age, your diagnosis and how much reproductive time you have.

Go deeper: What a failed cycle does and does not mean →

Before choosing between continuing naturally, simpler treatment or IVF, make sure eight things are actually known rather than assumed.

• your age and how long you have been trying
• whether ovulation is occurring, confirmed rather than predicted
• ovarian reserve, measured before any ovarian surgery
• tubal status
• a semen analysis for your partner
• any known condition and its extent, including previous surgery
• relevant medical conditions such as thyroid disease or diabetes
• how many children you hope to have, which affects timing

Most couples who feel stuck are missing at least two of these, and it is usually tubal status or the semen analysis.

Start with the bottleneck. Optimising things that were never the limiting factor is the most common way to spend a year without changing your chances.

And decide in advance when you will review. Drifting from month to month without a set point to reassess is how reproductive time disappears.
