Struggling to Conceive? Common Fertility Challenges Couples Face and When IVF Becomes an Option

Infertility is emotionally, physically and financially demanding. For many couples the path to parenthood is straightforward, but around one in six Australian couples experience difficulties conceiving and need medical help or assisted reproductive technology (ART). This article explains what infertility means, the common causes for people of all genders, how clinicians investigate fertility problems, the treatment options (including when IVF becomes a realistic option), and practical, evidence-based guidance on what to do next. The aim is to be thorough, clear and clinically accurate while remaining sensitive to the realities couples face.

What is infertility? When should you seek help?

Clinically, infertility is usually defined as the inability to achieve a pregnancy after 12 months of regular, unprotected intercourse (or attempted conception). Because fertility declines with age, professional guidance in Australia recommends seeking assessment earlier if a woman is aged 35 or older — typically after six months of trying. If there are known medical issues (irregular periods, history of pelvic infection or surgery, known low sperm count, or a partner with fertility-related conditions), you should seek help sooner. These timeframes are widely endorsed by Australian fertility bodies and clinics.

Key practical rules:

• Under 35 and no known risk factors: see your GP or fertility specialist after 12 months of trying.
• Aged 35 or over, or with known reproductive health issues: consider assessment after six months (or immediately if there are urgent concerns such as cancer treatment or known reduced ovarian reserve).

How common are fertility problems?

Infertility affects a substantial minority of couples. Estimates used in Australian clinical guidance put the prevalence at around one in six couples. When a cause is found, roughly one-third of fertility problems are attributable primarily to female factors, one-third to male factors, and the remainder are mixed or unexplained. These proportions emphasise why assessment of both partners is essential.

Major causes of infertility — an overview

Infertility is multi-factorial. Problems can involve ovaries and eggs, sperm, the reproductive tract (uterus and fallopian tubes), implantation, or a combination of factors. Below is a breakdown of the common causes clinicians see.

Female factors

Age and diminished ovarian reserve.

• A woman’s fertility declines with age because both egg quantity and egg quality fall. Ovarian reserve tests (for example, AMH blood test and antral follicle count on ultrasound) estimate remaining egg supply and help guide timing and treatment decisions. Age is the single most important predictor of natural and assisted conception success, and success rates for ART decline sharply after the mid-30s.

Ovulatory disorders.

• Problems with ovulation are common and include polycystic ovary syndrome (PCOS), hypothalamic amenorrhoea, and premature ovarian insufficiency. PCOS in particular is a frequent cause of irregular cycles and infertility.

Tubal disease and pelvic adhesions.

• Damage to or blockage of the fallopian tubes—often from pelvic infection, previous surgery or endometriosis—prevents eggs and sperm meeting naturally.

Endometriosis.

• The presence of endometrial-type tissue outside the uterus can disrupt pelvic anatomy, affect ovulation and implantation, and is linked with reduced fertility in a sizeable minority of women.

Uterine factors.

• Uterine abnormalities such as large fibroids, congenital uterine anomalies or an intrauterine scar can interfere with embryo implantation or pregnancy retention.

Other medical or systemic conditions.

• Thyroid disease, diabetes, autoimmune disorders and other systemic problems can influence fertility and pregnancy outcomes.

Male factors

Semen abnormalities.

• Problems with sperm count (oligozoospermia), motility (asthenozoospermia) or shape (teratozoospermia) are common contributors. A standard semen analysis is the cornerstone of male fertility assessment.

Azoospermia and obstructive issues.

• Azoospermia (no sperm in ejaculate) may be due to testicular failure or obstruction of the reproductive tract; some causes can be surgically treated or sperm retrieved for ICSI.

Genetic and hormonal causes.

• Genetic conditions and endocrine problems can affect spermatogenesis.

Varicocele and infections.

• Varicoceles and a history of mumps, sexually transmitted infections or prostatitis can impair sperm production or transport.

Unexplained infertility

After thorough evaluation, approximately one in four to one in five couples may have no identifiable cause. “Unexplained infertility” is a frustrating diagnosis but still leaves many possible treatment pathways including expectant management, ovulation induction, intrauterine insemination (IUI) or IVF.

Lifestyle and environmental factors that affect fertility

Lifestyle choices and environmental exposures can reduce fertility for both partners. Important modifiable factors include:

• Smoking (both partners): reduces ovarian reserve, sperm quality and increases miscarriage risk.
• Body weight: both underweight and overweight can disrupt ovulation; for men, obesity may impair sperm quality.
• Alcohol and recreational drugs: heavy alcohol and some recreational drugs negatively impact fertility.
• Caffeine: high intake may be associated with reduced fecundability; moderation is sensible.
• Occupational/environmental exposures: heat, radiation, certain chemicals and prolonged tight heat exposure (e.g. hot baths for men) may be harmful.
• Stress and sleep: while the direct causal links are complex, chronic stress and poor sleep patterns can interfere with reproductive hormones.

Addressing these factors often forms the first step in fertility care.

How fertility is investigated (what to expect)

Assessment usually begins with your GP and, if needed, referral to a fertility specialist. Typical investigations include:

Medical and sexual history.

• Menstrual history, sexual frequency, previous pregnancies, surgical and infection history, medications and family history.

Semen analysis.

• The first and most informative test for male factor infertility.

Ovulation assessment.

• Cycle regularity, progesterone measurement in the luteal phase, ultrasound of ovaries.

Ovarian reserve testing.

• AMH (Anti-Müllerian Hormone) and antral follicle count to estimate egg supply.

Pelvic ultrasound.

• To assess uterine shape, fibroids and ovarian morphology.

Tubal patency tests.

• Hysterosalpingogram (HSG), sonohysterogram or laparoscopy with dye can detect blocked tubes or adhesions.

Infectious and immunological tests where indicated.

The pattern of results directs management. Initial tests are relatively simple; specialist testing and procedures are offered when needed.

Treatment options — from simple to advanced

Treatment is tailored to diagnosis, age, personal preferences and resources. Common options:

1. Lifestyle modification and expectant management

For many couples, small changes and time will result in pregnancy. This is often the recommended path for younger couples with no major risk factors.

2. Ovulation induction

Oral or injectable medications (for example clomifene citrate or letrozole, and gonadotrophins) can stimulate ovulation for those with ovulatory disorders such as PCOS. Monitoring with ultrasound is usually required.

3. Surgery

Laparoscopic surgery may remove endometriosis or adhesions, and hysteroscopic surgery can correct intrauterine problems. Tubal surgery is less commonly performed now because IVF is often a more predictable route for tubal disease.

4. Intrauterine insemination (IUI)

Sperm are prepared in the lab and placed directly into the uterus around ovulation. IUI may be combined with mild ovulation induction and is used for selected cases such as mild male factor or unexplained infertility.

5. Assisted reproductive technology (ART) — IVF and ICSI

When IVF becomes an option. IVF is recommended when less invasive fertility treatments are unlikely to succeed or have failed, or when there are specific indications such as:

• Blocked or damaged fallopian tubes.
• Severe male factor infertility (very low sperm counts or quality).
• Failure of ovulation induction/IUI.
• Advanced maternal age or diminished ovarian reserve where time limits make IVF more appropriate.
• Known genetic disorders where preimplantation genetic testing is being considered.
• Certain cases of endometriosis or uterine problems.

What IVF involves. Controlled ovarian stimulation, egg retrieval, fertilisation in the laboratory (conventional IVF or intracytoplasmic sperm injection — ICSI — where a single sperm is injected into the egg), embryo culture and transfer to the uterus. Surplus embryos may be cryopreserved.

Success rates and age. IVF success depends strongly on the woman’s age and the quality/number of retrieved eggs. Younger women have higher live birth rates per cycle; success declines with advancing maternal age. Clinics report outcomes to national registries to help patients make informed choices.

6. Donor eggs, donor sperm and surrogacy

Donor gametes or embryos are used when one partner has no viable eggs or sperm, or for single people and same-sex couples. Surrogacy is legally complex and regulated differently across Australian states and territories; legal advice and specialist counselling are essential.

7. Fertility preservation (egg or sperm freezing)

For people facing medical treatments that threaten fertility (for example cancer therapy) or those wanting to delay parenthood, cryopreservation is an option. Egg freezing has higher success when done at younger ages.

Risks and considerations with IVF

IVF is generally safe but not without risks and trade-offs:

• Ovarian hyperstimulation syndrome (OHSS) — usually preventable and often mild, but can be severe in rare cases.
• Multiple pregnancy — transferring multiple embryos raises the chance of twins or higher-order multiples, with associated obstetric risks; many clinics now favour single embryo transfer policies where appropriate.
• Emotional and financial burden — treatment can be stressful and costly. Counselling is recommended and often available through clinics.
• Procedure-related risks — egg retrieval is an outpatient procedure with anaesthesia and small surgical risks.

Cost, access and regulation (Australian context)

Costs vary by clinic, treatment type and whether Medicare or other rebates apply. Australia has an established regulatory and accreditation framework for ART clinics; clinics report outcomes to national registries and operate under recognised standards. Because policies and funding can change, talk to your GP and potential clinics about expected out-of-pocket costs, rebates and public or private options that may be available in your state or territory.

Emotional, psychosocial and practical support

Struggling to conceive can cause grief, anxiety and relationship strain. Practical supports include:

• Counselling and psychological support (many clinics include or can refer to specialised fertility counsellors).
• Peer support groups and patient networks.
• Clear communication between partners about expectations and decisions.
• Financial planning and understanding the likely cost trajectory.

Questions to ask your GP or fertility clinic

When you see a GP or specialist at a fertility clinic Melbourne, consider asking:

• What do my test results mean and what is the likely cause of our difficulty conceiving?
• What are the evidence-based options for our specific diagnosis?
• What are the chances of success with each option given my partner’s ages and test results?
• What are the costs, potential complications and timeframes?
• Is counselling included in the pathway, and can you recommend support services?
• Is the clinic accredited, and how do their success rates compare with national data?

Practical checklist: first 90 days if you’re trying to conceive

1. Book a preconception appointment with your GP at a trusted fertility clinic in East Melbourne. Discuss folic acid (recommended before conception), vaccination status, medications and relevant health conditions.
2. Stop smoking and moderate alcohol; optimise body weight and exercise, but avoid extreme diets.
3. Track ovulation using cycle charts or apps if helpful; aim for regular sexual intercourse during the fertile window (every 1–2 days around ovulation).
4. If under 35, allow up to 12 months of trying unless there are risk factors. If 35 or older, consider earlier assessment at six months or sooner.
5. If concerned, ask your GP for initial tests (semen analysis, basic ovulation checks, and discussion of ovarian reserve testing).

When to escalate care urgently

See a clinician promptly if:

• You have an acute medical condition affecting fertility (for example pelvic infection).
• You are about to undergo gonadotoxic treatment (e.g. chemotherapy) and wish to preserve fertility.
• You have clear risk factors such as a history of significant reproductive surgery, severe irregular cycles, or known low sperm counts.

Final thoughts

Infertility is common, complex and often treatable. The path from concern to parenthood is rarely linear: for some couples simple lifestyle change and time will be enough; for others medical or surgical treatments, or ART such as IVF, will be required. Early, joint assessment of both partners gives the best chance of identifying causes and starting the most appropriate treatment. Importantly, emotional and practical support are central parts of care — fertility treatment is a medical journey and a life event that benefits from good information, clear communication and compassionate support.
