Introduction:
The ability to reproduce is an important part of human life, which is why infertility and its treatment, being a source of stress, can cause serious personal and social problems. There are many different definitions of infertility, but the WHO definition is most commonly cited; it defines infertility as a disease of the reproductive system characterized by the failure to achieve a pregnancy after 12 months or more of regular, unprotected sexual intercourse.

Aim of the research:
The aim of the study was to determine the level of perceived stress and life satisfaction in a group of women undergoing infertility treatment.

Material and methods:
The study was conducted at the 1st Military Clinical Hospital in Lublin. The study involved 110 women treated in the Gynaecology Ward due to infertility. A research tool was prepared for the study, which consisted of three sheets: a self-designed questionnaire, SWLS questionnaire and the PSS-10 questionnaire.

Results and conclusions::
The study revealed that women undergoing infertility treatment exhibited average levels of both perceived stress (mean score 21.49) and life satisfaction (mean score 19.52). A significant negative correlation was observed between stress and life satisfaction (p = 0.010), indicating that higher stress is associated with lower satisfaction. Significant predictors of higher stress were the patient’s age (p = 0.042), the duration of treatment (p = 0.017), and changes in partner relationships (p = 0.011). Conversely, the only factor with a significant positive association with higher life satisfaction was having children (p = 0.002).
