Impact of psychological stress on the outcomes of assisted reproduction in Tunisian infertile women.

Abstract

Introductionchildlessness is an emotionally difficult experience for infertile couples. Undergoing assisted reproductive treatments (ART) could generate further stress in these patients. Studies investigating the impact of anxiety on ART outcomes have shown controversial results. Moreover, there are no publications focusing on anxiety symptomsin infertile Tunisian couples.Methodswe conducted a prospective study including 79 infertile women undergoing in vitro fertilization at the Reproductive Medicine Unit of the Farhat Hached Hospital (Tunisia). Participants were asked to answer to the Beck anxiety inventory (BAI) on the day of oocyte retrieval. Accordingly, they were classified into the 3 groups: group A: very low anxiety (n= 36; BAI<21), group B: moderate anxiety (n= 24; 22≤BAI≤35) and group C: severe anxiety (n=19; BAI≥36). For each patient, two blood samples were collected to assess free cortisol level on the day of oocyte retrieval and on the day of embryo transfer.Resultsresults showed that women with primary infertility were significantly more stressed than those with secondary infertility (p= 0.011). Cortisol level was significantly higher on the day of embryo transfer than on the day of oocyte pick-up (p<0.0001). A lower implantation rate was found in severely anxious patients compared with moderately anxious women (p= 0.03) and those having low levels of anxiety (p= 0.001) and was negatively correlated to BAI score (r= -0.65; p= 0.001). Both clinical pregnancy and livebirth rates were similar among the three groups.Conclusionthe day of embryo transfer is the most stressful timepoint and psychological counseling is crucial to enhance implantation rate. Hence implantation took place, no effect of stress on pregnancy and live birth was found.
