    ABSTRACT: PURPOSE: To evaluate whether psychological stress, as well as changes in hypothalamus-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) at different time points during a first in vitro fertilization (IVF) cycle, correlates with the reproductive outcome. METHODS: A prospective study was conducted in 264 women undergoing IVF or intracytoplasmic sperm injection (ICSI) treatment between January 2009 and March 2010. Standardized psychological questionnaires were used to assess anxiety and depression. Norepinephrine and cortisol in serum were measured with specific assays. RESULTS: The non-pregnant women reported higher anxiety and depression scores at the pregnancy detection day compared with the pregnant group. Lower levels of norepinephrine and cortisol at the time of oocyte retrieval and lower levels of cortisol at the time of pregnancy test were found in women with successful treatment. Significant increases in serum norepinephrine and cortisol values were observed during ovarian stimulation. State Anxiety scores were negatively correlated with live birth rate, and positively associated with serum norepinephrine and cortisol values. CONCLUSIONS: State anxiety is associated with both pregnancy rate and live birth rate in IVF patients, an effect that is partly mediated by activities in the HPA and SNS.

    ABSTRACT: To evaluate whether psychological variables as well as changes in hypothalamus-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) at baseline and in response to a psychosocial stressor affect the chance of achieving pregnancy in women undergoing a first in vitro fertilization (IVF) cycle. Prospective study. Private IVF center. 264 women undergoing IVF or intracytoplasmic sperm injection (ICSI) treatment. Oocyte retrieval after ovarian stimulation. Standardized psychological questionnaires to assess anxiety and depression, and norepinephrine and cortisol in serum or follicular fluid measured by specific assays. Only a trend increase was found in psychological scores during treatment, which did not affect the ongoing pregnancy rates. On the oocyte retrieval day, a statistically significant increase in norepinephrine and cortisol concentrations was found. Lower concentrations of norepinephrine and cortisol, both in serum and follicular fluid, were found in women whose treatments were successful. Concentrations of steroid in serum before treatment and in follicular fluid were positively associated with the State Anxiety scores. Norepinephrine and cortisol concentrations may negatively influence the clinical pregnancy rate in IVF treatment. These biological stress markers could be one of the links in the complex relationship between psychosocial stress and outcome after IVF-ICSI.
