Introduction. The use of sisted reproductive technologies has had sufficient experience to reduce the risks associated with the technologies themselves. But pediatricians remain concerned about the health of children born from induced pregnancies because of the influence of the parents’ initial health on perinatal outcomes. Congenital malformations remain socially significant, the risk of which may be higher for children from induced pregnancy.Objective: to evaluate the effect of initial parental health and the methods of assisted reproductive technology used on the formation of congenital malformations and minor anomalies in children from singleton induced pregnancies.Materials and Methods. A retrospective cohort study was conducted using data on live-born children from singleton induced pregnancy born at the Avicenna Medical Center (Novosibirsk) over the period from 2007 to 2017 (n = 409). The reproductive, somatic, and infectious history of the parents and the methods of assisted reproductive technology used were assessed. Parental fertility treatment up to childbirth was performed in the same center, which ensured complete continuity of follow-up. Differences between the groups of children from SIP with and without congenital anomalies were determined using Pearson’s chi-squared test.Results and discussion. We found that children with congenital malformations and minor anomalies were more often born as a result of subsequent pregnancies; thawed embryos transferred at the blastocyst stage were used in assisted reproductive technology programs (p < 0.05); exacerbations of herpes type 2 infection were diagnosed during the current pregnancy (p < 0.05). In the group of children with only CM, the parents had a longer history of infertility (8.3 ± 1.2) years; pregnancy was achieved by transferring fresh embryos at the blastocyst stage (in 68.2% of cases). In the group of children without congenital malformations and minor anomalies, the maternal infectious history was more severe: there were significantly more frequent cases of urogenital infections (p < 0.05) and exacerbations of herpes simplex virus type 1 during pregnancy (p < 0.05).Conclusion. A set of measures aimed at an earlier solution of the infertility problem is necessary for the primary prevention of congenital abnormalities associated with the age and duration of parental infertility.
