Male Fertility FAQ: 30 Questions
About Sperm Count, Quality and Fertility

Sperm quality is broader than sperm count. It describes several characteristics that influence a sperm's ability to participate successfully in fertilization and reproduction.

When men hear “your sperm count is normal”, they often assume “my fertility is completely normal”. But concentration is only one part of the picture. A conventional semen analysis evaluates:

• Count, how many sperm are present, by concentration and total number
• Motility, how many are moving, and how many are moving progressively
• Morphology, what proportion meet strict criteria for normal shape
• semen volume and other semen characteristics

But reproductive function goes beyond these visible characteristics. Sperm also carry paternal genetic material that contributes to fertilization and embryo development, which is where sperm DNA integrity becomes relevant.

So a man can have normal concentration, motility and morphology and still have fertility difficulties. Equally, an abnormal parameter does not automatically mean sperm are incapable of fertilization. Sperm quality is not simply “good” or “bad”, parameters vary between samples, sperm vary within a sample, and fertility depends on the interaction between both partners.

Key takeaway: Sperm quality includes count, movement, morphology and other aspects of reproductive function. No single semen parameter provides a complete measurement of male fertility.

For a closer look at each of these parameters and what they mean individually, see our Sperm Quality FAQ.

Sperm DNA fragmentation refers to damage or breaks within the DNA carried by sperm. It is different from the count, motility and morphology measured on a standard semen analysis.

Every sperm carries paternal genetic material, and when a sperm fertilizes an egg that material contributes to the embryo. A sperm can look relatively normal under a microscope while still having abnormalities in DNA integrity, which is why this testing is sometimes discussed when a conventional semen analysis does not fully explain a couple's fertility history.

Results are often reported as a DNA Fragmentation Index (DFI). A higher DFI means a greater proportion of the sperm assessed showed fragmentation on that particular test. But there is an important limitation: there is no single universal DFI cutoff that applies identically across every laboratory and method. Different assays measure DNA damage differently, and thresholds vary.

So a result such as DFI = 25% should not be interpreted from an internet chart alone, without knowing:

• which test was used
• the laboratory's reference range
• the couple's fertility history
• the other semen parameters
• the clinical context

Fragmentation may be associated with oxidative stress, varicocele, smoking, age, certain illnesses or exposures, but an elevated DFI does not automatically reveal its cause. It is also not routinely required for every man at initial assessment.

Key takeaway: DNA fragmentation measures DNA integrity that routine count, motility and morphology do not capture. DFI must be interpreted according to the testing method and clinical context.

Higher sperm DNA fragmentation has been associated with reduced reproductive outcomes in some studies, but a high DFI does not mean natural conception is impossible.

Sperm must do more than reach the egg, they also contribute paternal DNA to the embryo, so it is biologically plausible that significant DNA damage could affect reproductive processes. Research has found associations with poorer outcomes in some populations.

But DFI is not a fertility score. A result of 20% does not mean an 80% chance of conception, and 30% does not mean only 70% of sperm can create a pregnancy. That is not how DFI works. The relationship depends on:

• the testing method used
• the degree of fragmentation
• the other semen characteristics
• male age and health
• the female partner's age and egg-related factors
• reproductive history
• whether conception is natural or assisted

The egg may also have some capacity to repair certain sperm DNA damage after fertilization, although that capacity is not unlimited and varies. This interaction is one reason male and female fertility should not be treated as two separate systems.

Key takeaway: Higher fragmentation may be associated with reduced fertility, but it does not make natural conception impossible and should be interpreted alongside both partners' factors.

Higher sperm DNA fragmentation has been associated with an increased risk of pregnancy loss in research, but it should not be assumed to be the cause of an individual miscarriage.

Historically, miscarriage investigation has focused heavily on the woman. But successful embryo development depends on genetic material from both the egg and the sperm, and higher fragmentation has been associated in some studies and meta-analyses with increased miscarriage risk, including in assisted reproduction.

However, miscarriage is multifactorial. Possible contributors include:

• chromosomal abnormalities in the embryo
• maternal age
• uterine factors
• certain endocrine or medical conditions
• genetic factors
• other causes, and sometimes no clear explanation is found

So saying “the sperm DNA caused it” without appropriate evidence is not responsible. Equally, after recurrent miscarriages, focusing exclusively on the woman while never considering the male partner leaves part of the picture unexplored. Recurrent pregnancy loss is a couple-level reproductive problem, and neither partner should be blamed.

Key takeaway: Elevated DFI has been associated with miscarriage risk, but miscarriage has many possible causes and cannot automatically be explained by one test result.

Sperm DNA fragmentation can change over time, and in some men it may improve when an underlying or modifiable contributor is identified and addressed. But improvement is not guaranteed, and treatment should depend on the cause.

Online advice tends to jump straight to “take CoQ10, zinc, selenium and antioxidants for 90 days”. That skips the important question: why is the fragmentation elevated? Potential contributors include:

• varicocele
• smoking
• oxidative stress
• certain environmental or occupational exposures
• fever or recent illness
• obesity and metabolic factors
• advancing paternal age
• some infections or inflammatory conditions
• prolonged exposure to excessive heat

Not every man will have an identifiable cause, and not every elevated DFI responds to the same intervention. Where a clinically significant varicocele is present, specialist evaluation can determine whether treatment is appropriate. Antioxidants have been studied extensively, but the evidence for improving pregnancy and live birth is not strong enough to assume every man with a high DFI needs a large supplement stack, correcting a documented deficiency is different from taking multiple high-dose antioxidants without an indication.

Abstinence interval can also influence fragmentation in some men, and clinicians may individualise ejaculation timing. And because sperm production and maturation take weeks to months, changes made today are not reflected in the next sample, but that should not become the promise “follow this plan for exactly 90 days and your sperm DNA will be normal”. Biology does not work to a guaranteed timetable.

Key takeaway: Fragmentation may improve when relevant contributors are addressed, but no universal supplement or lifestyle protocol is guaranteed to normalise DFI.

Related: Addressing modifiable contributors properly →

Yes. Sperm parameters can improve in some men, particularly when modifiable factors affecting reproductive health are identified and addressed. But improvement is not guaranteed, and not every cause of male infertility can be corrected through lifestyle alone.

Unlike the ovarian reserve a woman is born with, sperm are continually produced after puberty. This means concentration, motility and other characteristics can change over time. Potentially modifiable factors include:

• smoking
• excessive alcohol consumption
• anabolic steroid or external testosterone use
• obesity and metabolic dysfunction
• poor nutritional intake
• certain excessive heat exposures
• some occupational or environmental exposures
• untreated medical conditions
• varicocele in selected men

But there is an important distinction: supporting sperm health is not the same as curing male infertility naturally. A man whose sperm production is suppressed by external testosterone may need medical management. A significant varicocele may warrant specialist evaluation. A reproductive tract obstruction cannot be corrected with a fertility diet. And some genetic causes cannot be reversed through lifestyle.

So the first question should not be “what supplement improves sperm?” It should be “what is contributing to the abnormal result, and is any part of it modifiable or treatable?” Lifestyle optimisation should complement proper investigation rather than replace it.

Key takeaway: Sperm health can improve in some men, especially when modifiable contributors are addressed, but lifestyle changes cannot correct every cause of male infertility.

Related: Identifying what is actually contributing to the result →

Changes in sperm health generally take time, because sperm production and maturation occur over several weeks to months. This is why fertility interventions are usually assessed over roughly three months rather than after a few days.

You may have heard “sperm take 90 days to make”. That is a useful simplification, but the biology is more nuanced. Sperm develop through spermatogenesis inside the testes over roughly 70-plus days, after which they undergo further maturation and transport through the reproductive tract. The sperm ejaculated today began developing weeks ago.

So if someone stops smoking today, improves metabolic health, corrects a nutritional deficiency, changes a harmful exposure or begins treatment for an underlying condition, we should not expect the semen analysis to transform next week. It may take several months before effects become apparent.

But this does not mean “every man needs exactly 90 days and his sperm will become normal”. Some parameters change sooner, some later, and some may not improve substantially, and semen characteristics vary naturally between samples.

Reproductive time also matters. If the female partner is approaching an age where fertility declines significantly, spending repeated three-month periods trying different lifestyle protocols without proper evaluation may not be sensible. Both partners' timelines count.

Key takeaway: Meaningful changes are assessed over roughly three months because of the production cycle, but there is no guaranteed 90-day sperm transformation.

There is no single food proven to dramatically increase sperm count or cure male infertility. An overall nutrient-dense dietary pattern matters far more than adding one supposed “sperm-boosting” food.

You will see claims like “eat walnuts to double your sperm count” or “eat these five foods to increase motility”. Individual foods contain nutrients relevant to reproductive health, but male fertility cannot be reduced to a handful of ingredients. A useful foundation includes:

• Protein, eggs, fish, lean meat, dairy where appropriate, dal, beans, chickpeas, soy foods
• Fruits and vegetables, aim for variety rather than one “best fertility fruit”
• Healthy fats, nuts, seeds, fish, olive oil and other unsaturated sources
• Whole-food carbohydrates, whole grains, oats, rice, roti, millets, potatoes, legumes, fruit
• Key micronutrients, zinc, selenium, folate, vitamin B12, vitamin C, vitamin E, vitamin D, omega-3 fatty acids

Male fertility does not require eliminating carbohydrates, and extremely high protein intake is not automatically better for sperm. Knowing that a nutrient is involved in sperm biology does not mean taking more than required will improve fertility.

We would rather build a sustainable dietary pattern supporting overall and metabolic health than prescribe “2 Brazil nuts + 1 fertility juice + 10 almonds = better sperm”. Food is part of the fertility environment, not a guaranteed treatment for abnormal semen parameters.

Key takeaway: Male fertility is better supported by an overall nutrient-dense dietary pattern than by individual “sperm-boosting” foods.

Some supplements and antioxidants have been studied for male infertility, but the evidence is inconsistent, and no universal supplement stack has been proven to improve pregnancy or live-birth outcomes for every man. Commonly promoted options include CoQ10, L-carnitine, zinc, selenium, folate, vitamin C, vitamin E, vitamin D and omega-3 fatty acids.

Studies have reported improvements in certain semen parameters in selected populations. But three questions matter:

• Does improving a semen number mean more babies? Not necessarily, a supplement might improve motility without strong evidence that it increases live-birth rates.
• Does the man actually need the nutrient? Correcting a documented deficiency is different from taking large doses because a bottle is labelled “male fertility”.
• Are more antioxidants better? No. Normal oxidative processes have physiological roles, and unnecessary high-dose supplementation can have adverse effects or interactions.

Supplementation should be targeted rather than automatic. Ask: is there a deficiency? a dietary gap? a clinical reason? what evidence supports this? is the dose appropriate? could it interact with medications or conditions?

And if semen parameters are severely abnormal, supplements should not delay appropriate medical evaluation.

Key takeaway: Some supplements may influence semen parameters in selected men, but there is no evidence-based universal fertility stack. Supplementation should be individualised.

Regular physical activity and improved metabolic health may support male reproductive health, particularly in men with obesity or metabolic dysfunction. But weight loss is not a fertility treatment every man needs.

Obesity can be associated with changes involving reproductive hormones, testosterone, metabolic health, inflammation, testicular temperature, sexual function and semen parameters. So for some men, sustainable weight reduction may support reproductive function, but the goal should not be “lose 15 kg and your sperm will become normal”. The relationship is not that predictable.

Exercise itself provides benefits even without dramatic weight loss, supporting insulin sensitivity, cardiovascular health, body composition, sleep, psychological wellbeing and metabolic health. A balanced approach can include walking, moderate aerobic activity, resistance training and reducing prolonged sedentary time.

But more exercise is not automatically better. Extreme training, inadequate calorie intake, poor recovery or anabolic steroid use can work against reproductive health. This matters particularly in gym culture: a man may look extremely fit while using testosterone or anabolic steroids that suppress the hormonal signals required for sperm production. Appearance is not fertility.

Key takeaway: Exercise and sustainable weight management can support reproductive health, but extreme training, under-fuelling and anabolic steroid use work against it.

Low testosterone can be associated with fertility problems, but a low result does not automatically mean a man is infertile. Male fertility depends on the hormonal system controlling sperm production, not testosterone levels alone.

There is an important distinction between testosterone circulating in the blood and the hormonal environment required inside the testes for sperm production. Sperm production is regulated through communication between the brain, pituitary and testes:

• FSH (follicle-stimulating hormone) plays a central role in supporting sperm production within the testes
• LH (luteinizing hormone) stimulates Leydig cells to produce testosterone, and testosterone produced within the testes helps support spermatogenesis

So when testosterone is low, the important question is why. Contributors can include problems involving the testes, pituitary or hypothalamic disorders, obesity and metabolic dysfunction, certain medications, previous anabolic steroid or testosterone use, chronic illness, sleep-related problems and other endocrine conditions.

Symptoms such as reduced libido, erectile difficulties, low energy or changes in body composition cannot diagnose low testosterone by themselves. And critically: a blood testosterone level does not tell us what the sperm count is. A man concerned about fertility needs a fertility-focused evaluation, not testosterone testing alone.

Key takeaway: Low testosterone can be associated with impaired reproductive health, but assessing sperm production directly is more useful than interpreting testosterone in isolation.

Related: How the brain-pituitary-testes axis controls fertility →

Yes. Testosterone taken from outside the body can significantly suppress sperm production and, in some men, result in very low sperm counts or no sperm detected in the semen.

This sounds contradictory. If testosterone is the main male reproductive hormone, shouldn't taking more improve fertility? No, because of how the feedback system works. Normally: Hypothalamus → GnRH → Pituitary → LH + FSH → Testes → testosterone + sperm production.

When testosterone is introduced from outside the body, injections, gels, pellets, testosterone-containing treatments or anabolic-androgenic steroids, the brain detects the increased androgen signal and reduces GnRH, LH and FSH stimulation. The testes then receive less of the signalling needed to maintain the high local testosterone environment sperm production requires:

External testosterone → reduced LH/FSH signalling → reduced intratesticular testosterone → suppressed spermatogenesis. So blood testosterone may rise while sperm production falls. A man may experience increased muscle mass, improved libido and higher blood testosterone while producing fewer sperm.

If you are taking testosterone and want a baby: do not simply stop prescribed treatment or start fertility drugs on your own. Speak with a reproductive urologist or endocrinologist, there may be fertility-preserving or fertility-restoring strategies. Recovery after testosterone or steroid use can occur, but timing varies and it is not guaranteed, which is why fertility goals should ideally be discussed before starting therapy.

Key takeaway: External testosterone suppresses the hormonal signals needed for sperm production. Discuss fertility goals with a clinician before starting or changing testosterone treatment.

Related: Why external hormones shut down natural production →

Yes. Erectile dysfunction can make conception more difficult if it prevents or reduces successful intercourse during the fertile window, even when sperm production itself is completely normal.

Erectile function and sperm quality are different things. A man can have normal sperm with erectile dysfunction, or normal erections with abnormal semen parameters. For natural conception, sperm need to be deposited in the female reproductive tract around the fertile window, so repeated difficulty can mean missed opportunities.

There is also a fertility-specific problem: trying to conceive turns sex into a scheduled task, “she's ovulating tonight, we have to do it now”, and that pressure can contribute to performance anxiety. Erectile difficulty during timed intercourse does not automatically mean there is an underlying hormonal or sperm problem.

But persistent ED deserves proper evaluation. Contributors can include cardiovascular or metabolic conditions, diabetes, hormonal problems, certain medications, neurological factors, smoking, psychological factors and relationship or performance anxiety. ED can also signal broader health issues, so taking a supplement marketed for “male power” without understanding the cause is not a fertility strategy.

Key takeaway: Erectile dysfunction can reduce opportunities for natural conception, but erectile function and sperm quality are separate aspects of male reproductive health.

Frequent ejaculation can temporarily change semen volume, concentration and total sperm number in an individual sample, but normal masturbation does not cause male infertility.

Men sometimes believe they need to “save sperm” for days before the fertile window. But sperm production does not work like filling a storage tank that must remain untouched. Longer abstinence can increase volume and total number in some samples, yet it does not necessarily mean better overall quality, because motility and DNA integrity may behave differently at different intervals. There is no universal rule that the longer you abstain, the better your fertility.

For semen analysis, laboratories usually specify a recommended abstinence interval so the sample can be interpreted appropriately, follow the instructions you are given.

For natural conception the objective is different: have sperm available in the female reproductive tract during the fertile window. A couple generally does not need to avoid intercourse for a week to build up sperm, and masturbation does not permanently reduce sperm count or testosterone.

One situation deserves individual guidance: with a very low count, abnormal parameters, high DNA fragmentation or during fertility treatment, a clinician may recommend a specific ejaculation strategy. Sperm are continuously produced, conception depends more on timing and the couple's reproductive health than on preserving every ejaculation.

Key takeaway: Masturbation does not cause infertility. Frequent ejaculation can temporarily affect semen parameters, while very long abstinence is not automatically better.

For most couples trying naturally, intercourse every one to two days during the fertile window provides frequent sperm exposure without requiring perfect prediction of the exact moment of ovulation.

Sperm and egg have different reproductive lifespans. Sperm can survive several days in favourable conditions in the female reproductive tract, while the egg has a much shorter window after ovulation. This means conception is often more likely when sperm are already present before ovulation occurs, rather than waiting until ovulation has definitely happened.

Two practical approaches work:

• intercourse every one to two days across the fertile window
• or regular intercourse roughly two to three times per week throughout the cycle, which makes overlap with the fertile window likely when cycles are reasonably regular

Daily intercourse is fine if both partners are comfortable, but no couple should feel it is required. And prolonged abstinence solely to “save sperm” is generally unnecessary, regular intercourse across the window makes more sense than trying to produce one supposedly perfect ejaculation on ovulation day. If semen parameters are significantly abnormal, timing may need to be considered within the broader plan; the answer is not automatically “have sex less often so sperm can build up”.

There is a psychological side too. When every encounter becomes “OPK positive, we need to do it tonight”, tracking creates real pressure. The objective is adequate exposure during the fertile window, not perfect performance according to an app.

Key takeaway: Intercourse every one to two days during the fertile window is sufficient for most couples, and two to three times per week throughout the cycle also covers it.

Yes. Smoking is associated with poorer semen quality and sperm DNA damage, while heavy alcohol consumption can negatively affect reproductive hormones and male fertility.

Smoking exposes the body to numerous chemicals and can increase oxidative stress. It has been associated with changes in sperm concentration, motility, morphology, DNA integrity and overall reproductive health. The effect varies between individuals, so smoking does not mean a man is infertile, but if a couple is trying to conceive, stopping is one of the clearest modifiable steps a male partner can take.

Vaping should not automatically be considered a fertility-safe alternative. E-cigarettes can expose users to nicotine and other substances, and the long-term reproductive effects are still being studied.

Alcohol depends partly on amount and pattern. Heavy or chronic intake can affect testosterone and reproductive hormones, testicular function, sexual function and semen parameters. Evidence around occasional or moderate consumption is less consistent, so avoid both extremes, “one drink will damage your sperm” and “alcohol has nothing to do with fertility” are both wrong.

And lifestyle changes should involve both partners. Fertility preparation should not become a situation where the woman changes her entire diet and lifestyle while the man's health is ignored.

Key takeaway: Smoking is associated with poorer male reproductive health, and heavy alcohol consumption can affect hormones and sperm. Reducing relevant exposures is part of male preconception care.

The testes function best slightly below core body temperature, and repeated or substantial heat exposure may negatively affect sperm production in some men. But everyday heat exposure should not become a source of fertility anxiety.

• Saunas and hot tubs, frequent or prolonged high-temperature exposure may temporarily affect semen parameters, depending on intensity, frequency and duration
• Laptops, a laptop directly on the lap increases local temperature; using a desk instead is a reasonable precaution
• Tight underwear, the evidence that switching from briefs to boxers dramatically improves fertility is not strong; comfortable clothing avoiding excessive prolonged heat is reasonable, but fertility underwear will not solve significant male infertility
• Occupational heat, men regularly exposed through their work may have a far more meaningful exposure than someone who occasionally uses a sauna, and this belongs in the medical history

Keep this in perspective. If a semen analysis is severely abnormal, changing underwear while ignoring a varicocele, hormonal problem or testosterone use would miss the bigger issue.

Key takeaway: Significant or repeated testicular heat exposure may affect sperm production, but everyday heat is rarely the complete explanation for male infertility.

Yes. A varicocele can be associated with impaired sperm production and reduced semen quality in some men, but not every man with a varicocele is infertile or requires treatment.

A varicocele is an abnormal enlargement of veins within the scrotum, similar in concept to varicose veins, and it is relatively common. Some men with one have normal fertility. Others may have abnormalities involving sperm concentration, motility, morphology or testicular function. Varicoceles have also been studied in relation to oxidative stress and sperm DNA fragmentation.

Some men have no symptoms; others notice a dull ache or discomfort, heaviness in the scrotum, visible or palpable enlarged veins, or changes in testicular size. Sometimes it is found during a fertility evaluation.

Does every varicocele need surgery? No. Whether treatment is appropriate depends on whether it is clinically significant, the semen abnormalities present, fertility history, testicular findings, symptoms and the couple's reproductive circumstances. In selected infertile men with a clinically significant varicocele and abnormal parameters, treatment may be considered after specialist evaluation.

But surgery should not be sold as a guaranteed way to “increase sperm count and get pregnant”. Improvement varies, and pregnancy still depends on both partners. If a clinically significant varicocele is suspected, evaluation by a urologist or reproductive urologist is far more useful than trying to treat it with supplements.

Key takeaway: Varicocele can contribute to male infertility in some men, but many men with varicoceles remain fertile. Treatment decisions depend on clinical findings and the couple's situation.

Yes. Some causes of male infertility can be treated or managed without IVF or ICSI, but the appropriate approach depends on the cause, the severity and the fertility of both partners. Male infertility is not one disease, so there cannot be one treatment.

• Lifestyle modification, smoking, heavy alcohol, obesity and metabolic health, harmful occupational exposures, anabolic steroid use; but this cannot correct every cause
• Treating underlying medical problems, some hormonal disorders are medically treatable, and certain infections or conditions require specific treatment
• Testosterone-related suppression, if external testosterone or steroids are suppressing production, fertility-focused medical management may be required; do not attempt to correct this with supplements alone
• Varicocele, selected men with a clinically significant varicocele may benefit from treatment after evaluation
• Sexual dysfunction, addressing erectile or ejaculatory problems may improve the couple's ability to try naturally

In other situations the male factor may be severe enough that assisted reproduction offers a more appropriate path, IUI in selected cases, IVF, or IVF with ICSI, where a single sperm is injected directly into an egg. ICSI is particularly useful in certain forms of male-factor infertility, but it is not automatically required for every abnormal semen analysis.

The decision should weigh how severe the male factor is, whether it is treatable, the female partner's age, how long you have been trying and whether additional fertility factors exist. Spending a year improving semen parameters may not be the best strategy if the couple has another time-sensitive factor.

The objective should not be “avoid IVF at all costs”. It should be “identify what can reasonably be improved while choosing the path that gives this couple an appropriate opportunity to conceive without unnecessarily losing reproductive time”.

Key takeaway: Some male fertility problems improve or can be treated without IVF or ICSI, while others require assisted reproduction. The right path depends on cause, severity and both partners.

If IVF with ICSI does become the recommended path, our IVF FAQ explains what the process actually involves, from stimulation through to transfer.

An abnormal semen analysis is a reason to investigate further, not a verdict that you cannot become a father. The first thing many men do is search every number online and conclude: low motility = infertility, 2% morphology = terrible sperm, low count = IVF, high DFI = miscarriage. That is not how a semen analysis should be interpreted.

• Look at the complete report, volume, concentration, total number, total and progressive motility, morphology and other findings; the relationship between them matters
• Consider whether the test needs repeating, parameters vary naturally, and fever, abstinence interval or collection problems can influence a sample
• Review medical and reproductive history, testicular problems, undescended testes, surgery, infection, varicocele, medications, testosterone or steroid use, sexual dysfunction, smoking, alcohol, occupational exposures
• Seek specialist evaluation when appropriate, hormonal, genetic or anatomical testing depending on findings, rather than ordering every available test
• Address relevant modifiable factors, smoking cessation, alcohol reduction, metabolic health, nutrition, activity, sleep, avoiding anabolic steroids
• Be careful with supplement stacks, correct deficiencies and supplement where indicated; more pills do not automatically create healthier sperm
• Evaluate the couple, do not spend six months moving morphology from 2% to 4% while ignoring female age, ovulation, ovarian reserve, tubes or endometriosis
• Protect reproductive time, some interventions justify reassessment after several months, but waiting indefinitely for a “perfect” analysis costs time

The objective is not “get every semen parameter into the normal range”. It is “understand what may be reducing our chances of pregnancy, improve what can reasonably be improved, and choose the most appropriate path toward conception”.

A man can have an abnormal parameter and achieve pregnancy. Another can have a normal analysis and still be part of a couple experiencing infertility. The report gives us information. It does not give us the outcome.

Key takeaway: Interpret the complete report, repeat testing when appropriate, investigate significant abnormalities, address modifiable factors and evaluate fertility as a couple.

Fertilization and embryo development depend on both partners, so evaluating the female side matters equally. Our Egg Quality FAQ covers the parallel factors on the egg side, and if a previous IVF cycle didn't work, our Failed IVF FAQ explains how to interpret what happened at each stage.
