- BACKGROUND: The aim of the study was to investigate the effect of psychological stress before and during IVF treatment on the outcome of IVF, controlling for known physiological predictors METHODS: This is a prospective, longitudinal study A total of 166 women were studied during their first IVF treatment They answered questionnaires concerning psychological and social factors on two occasions Psychological well-being was measured by the Psychological General Well-Being (PGWB) index and psychological effects of infertility were assessed by 14 items RESULTS: In the analysis of the psychological variables, no differences were found between pregnant and non-pregnant women The total number of good quality embryos, the number of good quality embryos transferred, and the number of embryos transferred were significantly higher in the pregnant than in the non-pregnant group In a multivariate analysis, the number of good quality embryos transferred was the only variable that was independently associated with pregnancy CONCLUSIONS: We found no evidence that psychological stress had any influence on the outcome of IVF treatment When counselling infertile couples, it might be possible to reduce the stress they experience during the treatment procedure by informing them of these findings

- BACKGROUND: Both lifestyle factors and occupational and environmental factors have been suggested to affect the female reproductive system. In the present study, the separate and joint effects of several such factors are investigated. METHODS: Information on time to pregnancy (TTP) was available for 1578 women randomly selected from the general Swedish population. The information was collected retrospectively by using self-administered questionnaires. By means of logistic regression of survival data, fecundability odds ratios were determined for many factors. Multivariate models were used to determine which factors had the most impact on TTP. RESULTS: Several lifestyle factors were found to associate with TTP. However, only use of oral contraceptives prior to attempting to conceive, menstrual cycle length, age at conception and parity remained in the multivariate models. Together, these factors explained 14% of the variance in TTP. Excluding first and second month conceptions, only age at conception and menstrual cycle length remained in the multivariate models, together explaining only 8% of the variance in TTP. CONCLUSIONS: Although information on several factors was available, the multivariate model explained only a small fraction of the variation in the observed time to pregnancies. Furthermore, female biological factors seemed more important predictors of TTP than lifestyle factors.

The couple's decision-making in IVF : one or two embryos at transfer?
- 2005

Journal article (peer-reviewed)abstract
- The aim of this study was to evaluate the decision-making process and factors that contribute to the decision of IVF participants to choose one or two embryos at transfer.Methods: Two hundred and seventy-four IVF patients equally distributed in males and females were personally interviewed using a semi-structured questionnaire which included 82 items.Results: In the whole study population, previous childbirth [odds ratio (OR) 2.1; 95% confidence interval (CI) 1.9–3.6], and spare embryos to freeze (OR 23.6; 95% CI 11.2–54.5) emerged as the most important variables in patients who had one embryo transferred, while previous IVF treatments (OR 0.3; 95% CI 0.1–0.6) and the assumed increased pregnancy chance (OR 0.1; 95% CI 0.05–0.3) were the most important decision-making factors among those who had two embryos. The women were more satisfied with the information (83 versus 71%; P=0.02), and more aware of the risks with twin pregnancies (77 versus 66%; P=0.03) than the males. The women were also more concerned about their age. Knowledge about risks of multiple pregnancies was higher in females (77%) than in males (66%, P=0.03).Conclusion: The results of this study indicate that despite good information about the risks for complications with multiple pregnancies, many patients wish to have two embryos transferred. Spare embryos to freeze, improvement of pregnancy rate in single embryo transfer and young age of the woman are predictive of choosing single embryo transfer. However, the final decision must always be made in agreement with the physician.
