Objective:In the past few decades, new and more efficient techniques to help solve fertility problems have become widely available throughout the developed world. The aim of this study was to determine whether there were differences on psychopathology factors between women who had conceived after in vitro fertilization (IVF) and women who had conceived naturally.Methods:The sample was composed of 41 pregnant women of whom 28 women had conceived through assisted reproductive technology (IVF) and 13 had conceived naturally. Women were evaluated by week 20 of pregnancy at the Infanta Cristina University Hospital Obstetrics and Gynecology Service, in Badajoz. Women consented to complete the Symptom Checklist-90-Revised (SCL-90-R).Results:IVF women were characterized by higher scores on Anxiety Scale (t = 3.90; p = 0.045) and lower scores on Hostility Scale (t = 4.35; p = 0.041) than women who had conceived naturally. There were no differences in the others scales.Conclusions:IVF women appear to present a temperamental profile characterized by a tendency to anxiety. Further research is needed to firstly, confirm these preliminary findings, and secondly, to longitudinally explore its impact on pregnancy outcome and mother-infant attachment.

Several years ago the writer's attention was called to the apparently favourable influence of field peas on oats when the two were grown together. The rank growth of the oats, their dark-green colour and the delayed ripening gave every indication of an abundant supply of available nitrogen compounds. On the other hand, oats seeded without the peas, at about the same time, were less rank in their growth and matured at an earlier date. Further observation and inquiry strengthened the impression in the writer's mind that the associative growth of legumes and non-legumes is frequently advantageous to the latter in that they are supplied with nitrogen compounds derived either from the decay of the fibrous roots of the legumes, or from the soluble materials passing out of the roots into the surrounding soil.
