Sometimes, the decision to start hormonal testing and other investigations comes after months of trying, while other times it follows a clear sign that a more careful evaluation is needed. In my practice, fertility testing does not begin out of fear, but from the wish to correctly understand the situation and avoid wasting valuable time. For many couples, the first valuable step is not treatment, but a clear picture of ovarian function, ovulation, the uterus and the male factor.
When the Right Time for Fertility Testing Is
As a rule, I recommend fertility testing after 12 months of regular, unprotected sexual intercourse without achieving pregnancy when the woman is under 35 years old. After the age of 35, evaluation is worth starting earlier, usually after 6 months. And after 40, or when there are medical conditions that may affect fertility, there is no reason to postpone it.
There are also situations in which I recommend fertility testing without waiting for that interval. I am thinking of irregular menstrual cycles, absent periods, significant pelvic pain, suspicion of endometriosis, previous pelvic surgery, infections, recurrent miscarriages or a known history of altered sperm parameters. In these contexts, early investigation is useful because it can guide us more quickly toward the likely cause and the appropriate next steps.
For me, one important point is explaining that fertility testing is not addressed exclusively to the woman. Fertility is a couple’s reality, and proper evaluation should be planned in parallel, not in very delayed stages. That is exactly why the first discussions need to be calm, concrete and focused on the information that changes medical decision-making.
What We Check in the First Tests and Why It Matters
When I begin fertility testing, I first look at the basic elements, the ones that offer an initial map of the situation. One direction is the evaluation of ovulation and ovarian reserve, through hormonal tests correctly chosen according to the context and the day of the cycle. The results do not tell the whole story on their own, but they help me understand whether the ovaries are functioning predictably and whether there are signs that call for further investigations.
At the same time, I check the anatomy of the reproductive system. A well-performed transvaginal ultrasound can show essential information about the uterus, the endometrium, the ovaries, the presence of cysts, fibroids or other changes that may influence the chances of conception. Sometimes, this very simple step clarifies what is needed next and what is not useful to do too early.
Fertility testing also often includes evaluation of the male partner, usually through semen analysis and, when needed, additional investigations. I often say that this is one of the most important early decisions, because it can significantly shorten the path to a correct diagnosis. When we evaluate both partners from the beginning, we avoid assumptions and build a more realistic plan.
How We Correctly Interpret Results Without Rushed Conclusions
One of the most common mistakes is interpreting a single test in isolation. In reality, fertility testing does not mean placing a quick label after one result that is slightly outside the reference range. What matters to me is the context: age, medical history, cycle regularity, duration of attempts, symptoms and the correlation between blood tests and ultrasound.
That is why I tell patients that one hormonal result is not equal to a verdict, and one ultrasound is not equal to a complete prognosis. Fertility testing is useful precisely because it organizes the information and shows us what is relevant now, what is worth monitoring and what has no value if done too early or outside the clinical context. Good evaluation means rigor, not haste.
In some cases, after this first assessment, the next step is ovulation monitoring, evaluation of tubal patency or a discussion about treatment options. In others, I recommend only correcting modifiable factors and a period of follow-up. Not every couple reaches complex procedures, but it is important that the decision is made based on data, not on impressions.
“You deserve to be heard, seen, treated with respect, and supported throughout your life.”
Frequently Asked Questions
How soon should I start fertility testing if I am over 35?
In general, after 6 months of trying without achieving pregnancy, it is reasonable to begin evaluation. If there are irregular cycles, important gynecological history or other clinical suspicions, fertility testing may be recommended even earlier.
Do the first tests always show the exact cause?
Not always. The first investigations are meant to guide the diagnosis and identify the most common causes. Sometimes they are enough, while in other cases additional steps are needed to fully understand the clinical picture.
If my period is regular, does that mean everything is fine?
Not necessarily. A regular cycle is a useful sign, but it does not exclude all causes of infertility. That is why proper evaluation also looks at the uterus, the tubes, ovarian reserve and the male factor.
Does starting investigations mean I will need IVF?
No. Fertility testing does not automatically mean in vitro fertilization. For some couples, only diagnostic clarification, targeted treatment or proper timing is needed. For others, options may also include procedures such as in vitro fertilization (IVF).
The Role of Dr. Andreas Vythoulkas in Fertility Evaluation
In the initial evaluation, my role is to select the investigations that make sense for the patient and for the couple, not to recommend one standard list for everyone. What matters to me is explaining clearly why we are doing each step, what answer I expect from that test and how the results connect to one another. Fertility testing is truly useful when it is personalized and integrated into a coherent medical reasoning process.
I also believe it is important for patients to understand not only the diagnosis, but also the possible path after the diagnosis. For those who later move toward more advanced therapies, it is natural to also have a clear picture of the medical and emotional journey, including from the perspective of the patient experience in IVF. When information is explained well from the beginning, decisions become more grounded and unnecessary anxiety decreases.
