MATERIALES Y MÉTODOS: Estudio observacional, transversal, retrospectivo y analítico. Se incluyeron pacientes que terminaron el embarazo en el Instituto Nacional de Perinatología Isidro Espinosa de los Reyes; se excluyeron las embarazadas con expediente clínico incompleto, terminación del embarazo antes de las 22 semanas. Se analizaron y compararon las principales consecuencias perinatales en ambos tipos de embarazos. El análisis de asociación entre terapia de reproducción asistida y complicaciones perinatales se hizo mediante una regresión logística simple y ajustada por variables confusoras.  RESULTADOS: De 448 ciclos iniciados, se analizaron 98 embarazos únicos logrados por reproducción asistida; menor probabilidad para recién nacido pretérmino (p &lt; 0.05) e ingreso a la unidad de cuidados intensivos neonatales (p &lt;0.05) y embarazos múltiples; una probabilidad significativa de amenaza de parto pretérmino versus embarazos espontáneos (p &lt; 0.05).  CONCLUSIONES: Se registraron menos complicaciones perinatales en embarazos únicos por reproducción asistida y en embarazos múltiples mayor probabilidad de amenaza de parto pretérmino sin mayor prevalencia de recién nacido pretérmino. La adecuada atención multidisciplinaria previa a la concepción tiene mayor peso en las repercusiones perinatales que la técnica de fertilización asistida por sí misma.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  BACKGROUND: As demand for assisted reproduction techniques has increased, so have concerns about associated perinatal outcomes and whether they are different from spontaneously achieved pregnancies.  OBJECTIVE:  to describe and compare perinatal outcomes of pregnancies achieved by assisted reproduction versus spontaneous pregnancies.  MATERIALS AND METHODS:  Observational, cross-sectional, retrospective, analytical study. Pregnancies with resolution within the institute were included; those with an incomplete clinical record, termination of pregnancy before 22 weeks were excluded. The main perinatal results in both types of pregnancies were analyzed and compared. The analysis of the association between assisted reproduction therapy and perinatal complications was made by a simple logistic regression and adjusted for confounding variables.  RESULTS:  Of 448 cycles initiated, 98 pregnancies achieved by assisted reproduction were analyzed, observing in single pregnancies; lower probability for preterm newborns (p &lt;0.05) and admission to the neonatal intensive care unit (p &lt;0.05) and in multiple pregnancies; a significant probability to present threat of preterm delivery versus spontaneous pregnancies (p &lt;0.05).  CONCLUSIONS:  There were fewer perinatal complications in single pregnancies for assisted reproduction and in multiple pregnancies a greater probability of threat of preterm delivery without a higher prevalence of preterm newborn, concluding that having an adequate preconceptional multidisciplinary management has a greater weight in perinatal outcomes than Fertilization technique assisted by itself.]]></p></abstract>
