Background. Multiple pregnancy is in itself already a risk factor for the course and outcome of the pregnancy and birth. Its frequency in in-vitro fertilisation is approximately twenty fold in comparisori to natural conception which is also why it is one of the main problem areas of pregnancy and birth after an IVF-ETprocedure. The aim of our research is to determine whether the twins, born after an IVF-ETprocedure are any different than twins,born after spontaneous conception. Methods. The research was retrospective in nature. It included 1511 twin pregnancy patients who gave birth to twins between April 1987 and May 1995 and between January 1997 and December 1999. Our research group consisted of 255 mothers and 510 twins, bornafter an IVF-ETprocedure. The research was divided into a cohort and controlled study. In the cohort study the research group was compared to the entire Ljubljana cohort of 1256 mothers and 2512 twins resulting from spontaneous conception. In the controlled study 93 mothers and 186 twins from the research group were compared with 93 mothers and 186 newborns after spontaneous conception. In this group the mothers matched the research group in age, parity and birth year. The course of and complications during the pregnancy, and the course, complications and outcome of the birth as well as the characteristics of the newborns were compared. Results. Certain serious complications during the course of the pregnancy, including hypertension, gestation diabetes and threatened preterm labours, were no more frequent with the IVFgroup of mothers with twin pregnancy than with the control group. However more bleeding in the first trimester and less proteinuria were determined in comparison to the control group. (Abstract truncated at 2000 characters).
