Deliveries and children born after in-vitro fertilisation in Sweden 1982–95: a retrospective cohort study

Assisted conception and retinopathy of prematurity: 8-year follow-up study

“…13 The higher incidence of prematurity in AC births is primarily explained by the greater number of multiple births in this group. 14 McKibbin's study, between August 1991 and December 1994, found that 46.0% of babies born after AC were one of twins and 18.6% one of triplets. In this study, the rates have fallen to 36.9% one of twins and 1.5% from triplet births (Figure 1).…”

Meta-analysis of cancer incidence in children born after assisted reproductive technologies

“…Out of the 14 studies, five (Bergh et al, 1999;Ericson et al, 2002;Pinborg et al, 2003Pinborg et al, , 2004a were partially overlapping, therefore only the two most recent publications, with the larger cohort were included in the meta-analysis (Pinborg et al, 2004b for the Danish data set, Ericson et al, 2002 for the Swedish data set). The metaanalysis was therefore performed on 11 of the 14 data sets (Table 2), which reported pertinent, nonoverlapping, and comparable data.…”

Assessing the Risk of Cerebral Palsy in Children Born after Assisted Conception – The Role of Multiple Pregnancy and Preterm Delivery / Procena rizika od cerebralne paralize kod dece začete vantelesnim oplođenjem – uloga višestruke trudnoće i prevremenog rođenja

“…The chances of adverse obstetric and neonatal outcome of pregnancies are increasing with age (35). Results of the research published at the end of last century noted a tendency toward a strikingly different age and parity distribution of the women who delivered after IVF when compared to that of the general population (36). The risk ratio of being aged younger than 30 years (stratified for year of birth) was 0.23 (95% CI: 0.22-0.24) and of the pregnancy being the first was 1.49 (95% CI: 1.46-1.53) (36).…”
