Psychological assessment and follow-up after in vitro fertilization: assessing the impact of failure

Christopher R. Newton; Margaret T. Hearn; A. Albert Yuzpe

The present study was conducted to assess the immediate psychological impact of failed in vitro fertilization (IVF). Emotional status and marital functioning were also examined pre-IVF, and both demographic information and psychological test scores were evaluated as predictors of reaction to treatment failure. After a failed first cycle, both males and females showed significant increases in anxiety and depressive symptoms. Although group means were not clinically elevated and most participants were coping adequately, the prevalence of both mild and moderate depression increased substantially, particularly among women. In addition, women without children were a subgroup particularly vulnerable to the stress of failure. Predisposition towards anxiety, pre-IVF depressive symptoms, and fertility history were the most important predictors of emotional response. Treatment implications of these findings were discussed.

Memory complaints associated with the use of gonadotropin-releasing hormone agonists: a preliminary study

Christopher R. Newton; Dianne Slota; A. Albert Yuzpe; Ian S. Tummon

OBJECTIVES To study the effect of GnRH agonist (GnRH-a) treatment on memory and to assess the role of psychological factors. DESIGN A randomized prospective study. SETTING An academic teaching hospital. PARTICIPANTS Women with endometriosis and infertility or endometriosis alone. MAIN OUTCOME MEASURES Memory Observation Questionnaire, Profile of Mood States, Health Concerns scale, a weekly diary of adverse effects. RESULTS Perceived memory functioning decreased during GnRH-a administration and by the final week of treatment 44% of women reported moderate to marked impairment in comparison to community norms. Prospective memory was most affected and withdrawal of GnRH-a treatment resulted in a return to normal memory functioning. Impairment was not related to excessive health concerns or mood changes and was uncorrelated with other adverse effects. CONCLUSIONS Memory disruption may be a more common side effect of GnRH-a treatment than currently is recognized. Problems were temporary and more likely a result of rapid estrogen depletion than a consequence of mood, somatic distress, or personality factors.
