In more than 15 years of fertility practice, I have learned that one of the most important decisions is often made before IVF itself begins: understanding what is actually preventing a couple from conceiving.
I regularly meet couples who arrive with a very clear idea that IVF is the next step. Sometimes it is. But in other situations, the more important first question is: “What have we found so far, and what are we trying to treat?” That distinction can change the entire treatment plan.
Infertility is not one disease with one treatment. It can involve male factors, female factors, a combination of both, or no clearly identified cause. Current guidance from the World Health Organization and professional reproductive-medicine societies therefore supports a structured evaluation before choosing the level of treatment. [1–3]
IVF Is a Treatment, Not a Diagnosis
IVF is a powerful tool in reproductive medicine, but it should not become the diagnosis itself. The reason a couple is having difficulty conceiving should guide the conversation about whether IVF is appropriate, whether another treatment may reasonably be tried first, or whether a more focused evaluation is needed.
For example, a couple with severely damaged or blocked fallopian tubes may have a very different treatment pathway from a couple whose main issue is ovulation. Likewise, significant male-factor infertility can change the reproductive strategy. Some couples may have unexplained infertility, where the evaluation does not identify a single cause and treatment decisions need to consider age, duration of infertility, previous treatment and the couple’s preferences. WHO’s 2025 infertility guideline specifically supports a stepwise approach that considers clinical findings as well as patient preferences. [1]
What Should Be Evaluated Before Choosing IVF?
1. Both partners
Infertility should be approached as a couple’s reproductive-health issue. I have seen situations in which the woman underwent several investigations while the male partner had not yet had a basic fertility evaluation. Current AUA/ASRM guidance recommends that both partners undergo concurrent assessment. A semen analysis is an important part of the initial male evaluation, with further assessment guided by the clinical findings. [2]
2. Age and reproductive history
Age is an important part of fertility assessment, particularly for women, because reproductive potential changes with increasing age. The timing and intensity of evaluation may therefore differ according to age and clinical history. Previous pregnancies, miscarriages, surgeries, duration of infertility and earlier treatment attempts also help a fertility specialist understand the situation rather than viewing one test in isolation. [3,4]
3. Ovulation, uterus and fallopian tubes
Depending on the history, evaluation may look at ovulatory function, the structure of the reproductive tract and, when indicated, whether the fallopian tubes are open. The choice of tests should be driven by the clinical question. More testing is not automatically better care; unnecessary investigations can add cost, anxiety and delay without changing management. [1,3,4]
4. Ovarian reserve — with the right context
Tests such as AMH and antral follicle count can help estimate ovarian response to stimulation, particularly when planning assisted reproduction. But they should not be treated as a simple “fertility score.” ASRM notes that ovarian-reserve tests are more useful for predicting oocyte yield than independently predicting reproductive potential, and that results should be interpreted alongside age, diagnosis and the overall clinical picture. [5]
5. Previous treatment and the couple’s goals
A fertility plan should also reflect what has already been tried and what matters to the couple. One couple may want the least invasive reasonable treatment first. Another may need to move more quickly because of age, a known tubal factor, severe male-factor infertility or another clinically important consideration. The goal is not to follow a fixed sequence for everyone; it is to match treatment intensity to the problem being addressed.
Why Two Couples With “Infertility” May Need Different Treatment
Consider two couples who have both been trying for two years. On paper, their problem sounds similar. Clinically, it may not be.
One couple may have regular ovulation but severely compromised tubal function. Another may have normal tubes but substantial male-factor infertility. A third may have irregular ovulation associated with an endocrine or ovulatory disorder. A fourth may have no specific cause identified after standard evaluation. Their treatment discussions will not necessarily look the same.
This is why I prefer to explain treatment plans in terms of the problem we are trying to solve. Patients deserve to know not only what treatment is being proposed, but also why it is being proposed for them.
When IVF May Be Appropriate Without a Long Series of Earlier Treatments
There are also situations in which moving to IVF sooner may be reasonable. For example, significant tubal disease, some forms of severe male-factor infertility, or situations in which age and ovarian factors make delaying treatment less attractive may change the discussion. The point is not that IVF should always be used early. It is that the timing of treatment should be based on the couple’s diagnosis, prognosis, previous treatment and preferences rather than a fixed rule applied to everyone. [1–4]
Does Starting With More Tests Always Mean Better Care?
Not necessarily. Modern fertility care includes many investigations and treatment add-ons, but availability is not the same as necessity. A good evaluation is selective: each test should have a clinical purpose and a reasonable chance of changing management.
The 2021 ASRM committee opinion on infertility evaluation, for example, notes that several advanced tests should not be part of the routine evaluation unless there is a specific clinical indication. This is an important principle for patients: a longer test list is not automatically a better test list. [3]
Questions Patients Can Ask Before Starting IVF
- What is the most likely cause of our infertility based on the evaluation so far?
- Have both partners been assessed appropriately?
- Why is IVF being recommended in our particular situation?
- Are there reasonable alternatives, and what would make us choose one over another?
- Which findings are well established, and where is the evidence still uncertain?
- How will our age, previous treatment and other medical factors change the plan?
These questions do not challenge the doctor; they improve the conversation. The more clearly a couple understands the reasoning behind a treatment plan, the easier it becomes to make an informed decision.
A More Individualised Way to Think About IVF
My approach is to think of IVF as one part of a larger fertility-care pathway, not as the starting point for every couple. The right plan begins with understanding the couple, identifying the most likely contributing factors, discussing realistic options and then choosing the treatment that makes clinical sense for that situation.
There is no single test that can explain every case of infertility, and no single treatment that is right for every couple. Evidence-based care means using the information we have, being honest about what we do not yet know, and revisiting the plan when new information becomes available.
For couples considering IVF, the most useful question may therefore be not “Which IVF treatment should we choose?” but “What have we learned about our fertility, and why is this treatment appropriate for us?”
A careful diagnosis does not always make the fertility journey simple. But it can make the next step more understandable, more focused and more meaningful.
