RESUMO
INTRODUCTION: Infertility treatments such as in vitro fertilization (IVF) impose substantial distress. However, the specific role of individual contributory factors remains unclear. We therefore compared treatment-related psychological stress in IVF treatments with (cIVF) and without (NC-IVF) gonadotropin stimulation, as cIVF includes potentially stressful factors such as ovarian stimulation, anesthesia, embryo selection and cryopreservation, whereas NC-IVF does not. MATERIAL AND METHODS: Women were offered to have cIVF or NC-IVF. Validated psychological questionnaires filled in online before, during and after completed treatment cycle(s) at home were used to analyze psychological distress and treatment-related satisfaction and quality of life. To avoid different pregnancy rates in the two treatment groups, one cIVF was compared with three NC-IVF therapies, resulting in the same cumulative pregnancy rate. RESULTS: Data from 57 NC-IVF and 62 cIVF patients were evaluated. NC-IVF resulted in a similar overall clinical pregnancy rate than one cIVF. NC-IVF patients had a significantly lower level of depression (CES-D, 13.4 vs. 15.7, p < 0.05) and a higher satisfaction with the treatment (Treatment FertiQoL, 67.9 vs. 62.9, p < 0.05) compared with cIVF patients. The level of psychological distress increased during c-IVF treatment and decreased during NC-IVF treatment. In contrast, during NC-IVF treatment there was a significant increase in satisfaction with the treatment, whereas satisfaction with treatment in the cIVF patients decreased. CONCLUSIONS: Factors other than just pregnancy rate seem to have an impact on psychological stress in IVF treatment. Due to reduced psychological stress in NC-IVF, this treatment could be especially considered in psychologically stressed women.
