Vitro Fertilization

Multiple pregnancy is currently considered an important social and research problem, because it is often associated with a number of complications, such as premature birth and extremely low birth weight. Multiple pregnancies are facilitated by late reproductive age of the mother and in vitro fertilization (IVF) with the transfer of several embryos. In this review, we analyze specific characteristics of multiple pregnancies after IVF. Key words: twins, neonatal outcomes, in vitro fertilization

To assess the physical and mental development of infants born after in vitro fertilization (IVF), we performed a general physical and developmental examination (Bayley and Stanford-Binet scales) on a cohort of 116 IVF children, conceived and born at our institution between February 1985 and March 1989, and on 116 non-IVF matched controls. Study and control groups were each composed of 66 singletons, 19 pairs of twins and 4 sets of triplets, whose age at examination ranged from 12 to 45 months. The developmental indices of IVF infants were within the normal range and did not differ from those of their matched controls. The indices were positively correlated to gestational age, birth weight, head circumference at birth and at examination, and mother's education. Mean birth weight, gestational age, and birth weight percentile of IVF infants were lower than the mean of the healthy population. Mean percentiles of weight and length at examination (mean age 22.4 months) were equally low but did not differ from those of the matched controls. However, mean percentiles of head circumference at birth and at examination compare well with the normal mean, both in IVF and control groups. Twins and triplets (IVF and controls) had significantly lower physical and mental indices as compared to singletons.

Abstract The aim of this study was to determine zootechnical and health performance of Girolando calves born with high or low birth weight, and compare metabolic parameters between groups. The study was carried out on a commercial dairy farm located in Passos, Minas Gerais, Brazil. In this sense, a hundred Girolando calves were divided into 2 groups: Control, which consisted of calves that were born weighing ≤ 35 kg; and HBW, calves that were born weighing > 35 kg. Calves were monitored for zootechnical parameters; epidemiological indexes such as morbidity, mortality, recurrence of diarrhea, pneumonia; as well as serum concentrations of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, cholesterol, triglycerides, paraoxonase1, albumin, urea and globulin). Calves from the HBW group had a higher mortality rate as well as a tendency to more cases of pneumonia, but no effect on zootechnical performance was seen. The reasons for the differences in mortality need to be clarified since our study found no changes in biochemical parameters between the groups. The results allow us to conclude that Girolando calves from in vitro fertilization that are born heavier have a greater chance of clinical complications and a higher mortality rate, but the birth weight does not influence the zootechnical performance.
