Stress and IVF: does stress lower the chance of success?

The study cited most often is a meta-analysis published in the BMJ in 2011 by Boivin and colleagues, which pooled 14 studies including about 3,500 women undergoing a cycle of assisted reproduction. The authors found no association between the level of emotional distress before treatment and the chance of pregnancy. That included women with high levels of anxiety or depressive symptoms. Later studies and more recent reviews have reached similar conclusions, and ESHRE sessions in 2026 repeated the message that stress itself does not lower IVF success.

There is a practical reason why this message matters. When patients believe that stress determines the outcome, they take on an impossible task: controlling their feelings during a period that is difficult by its very nature. That creates a vicious circle, stress about being stressed, and after an unsuccessful cycle it leaves behind a guilt that belongs to no one. The reasons a cycle does not end in pregnancy are mostly biological: embryo quality, age, endometrial receptivity and chance.

Stress has a measurable effect, but not the one usually assumed. It is the main reason couples stop treatment before finishing the cycles they had planned, even when their cumulative chances were still good and even when cost was not the main obstacle. Because IVF success accumulates across several cycles, stopping early does affect the final outcome. That, rather than the biology of a single transfer, is where the real link between wellbeing and results lies.

Beyond that, prolonged stress affects sleep, concentration, the relationship with a partner, work and keeping to medication schedules. Those are reason enough to take wellbeing seriously, without having to present stress as the cause of failure. The ESHRE guideline on psychosocial care places emotional support inside routine fertility care, as a responsibility of the team rather than something the patient has to ask for.

The first thing that helps is clear information and realistic expectations: knowing what happens at each stage, how long it lasts, what is normal and what is not. Uncertainty is harder to carry than difficult news. Next comes structured support: counselling with a professional who knows the fertility field, cognitive and behavioural approaches and mindfulness-based programmes have shown improvements in anxiety and quality of life during treatment.

Simpler things help too: involving the partner in consultations and decisions, contact with people who have travelled the same road, planning a break between cycles rather than pressing on at any cost, and limiting comparison on social media, where mostly the happy endings are visible. Lifestyle basics, regular sleep, moderate movement, a Mediterranean-style diet and not smoking, are linked with better wellbeing; they are not a condition for success and should not be turned into a new list of obligations.

Sadness, anger and disappointment are normal reactions to a real loss. They become worrying when they persist, when they do not ease as the days pass, or when they block everyday life. Signs that deserve a conversation with a professional are: low mood lasting more than two weeks, anxiety that stops you working or sleeping, loss of interest in things you used to enjoy, withdrawing from family and friends, or thoughts that nothing has any meaning. These are not signs of weakness and they do not call for patience; they call for help.

In Kosovo, counselling services specialised in fertility are limited, so the team looking after you, your family doctor, your family and one or two trusted friends take on a larger role. Say plainly what you need; people often stay silent because they do not know how to help. And keep in mind the main message of this topic: you did not cause this with your feelings.
