Short answer: Stress appears to affect fertility, albeit indirectly. Studies have linked high stress to a slightly lower chance of conception during the fertile window and to hormonal imbalances via cortisol. At the same time, many people get pregnant amidst stressful circumstances – so stress is rarely the full explanation, and definitely not something to blame yourself for.
How can stress affect fertility?
During stress, the body's stress system (HPA axis) is activated, and cortisol levels rise. Chronically high cortisol levels can disrupt the balance of hormones that control ovulation and the menstrual cycle, and in men, stress has been linked to slightly poorer sperm quality.
What does research say?
A study that followed women during their fertile window found that those with the highest stress markers had a lower probability of becoming pregnant that cycle. A systematic review of cortisol and infertility points in a similar direction. At the same time, researchers emphasize that there is no simple cause-and-effect relationship – stress often affects indirectly, through sleep, lifestyle, and well-being.
An important nuance
Being told to "just relax" is rarely helpful, and stress is not a mistake one makes. It's more about feeling as good as you can during a period that is often stressful in itself.
What can you do?
Sleep, appropriate physical activity, relaxation, and social support can help. Many also find relief in talking to others in the same situation or with a counselor. In cases of prolonged low mood or anxiety – seek support from healthcare.

Stress can have an indirect impact, but is rarely the sole cause. Many people get pregnant during stressful periods.
Does relaxation help?
It can support both well-being and the factors affected by stress, but should be seen as part of the overall picture.
