MATERIALES Y MÉTODOS:  Estudio descriptivo, retrospectivo y observacional efectuado en pacientes con diagnóstico de infertilidad atendidas en el Departamento de Biología de la Reproducción Humana del Instituto Nacional de Perinatología Isidro Espinosa de los Reyes, Ciudad de México. Criterios de inclusión: pacientes infértiles entre 18 y 43 años a quienes se realizó histeroscopia. Criterios de exclusión: pacientes del servicio de Reproducción Humana a quienes no se les realizó histeroscopia o ésta fue fallida. Se utilizó el paquete estadístico para las ciencias sociales (SPSS Statistics) versión 20.0. El análisis estadístico fue descriptivo, con media, desviación estándar o porcentaje.  RESULTADOS:  Se analizaron los expedientes físicos de 440 pacientes infértiles a quienes se efectuó histeroscopia. Las características demográficas incluyeron edad, IMC, tipo y años de infertilidad. Los hallazgos histeroscópicos fueron: cavidad uterina normal 38.4% y anormal 61.6%, pólipo o endometrio polipoide en 34.3%, malformación mülleriana 13.4%, sinequias 10.7%, leiomioma 7.3%, hiperplasia endometrial 1.4%, adenomiosis 0.9%, cuerpo extraño 0.9%. El 7.5% consiguió el embarazo espontáneo y a 21.8% se les practicaron distintas técnicas de reproducción asistida y se logró el embarazo en 34.3%.  CONCLUSIONES:  La evaluación de la cavidad uterina es un requisito indispensable del estudio de las pacientes infértiles; en esta búsqueda más de la mitad tuvieron hallazgos histeroscópicos anormales.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  OBJECTIVE:  To describe the prevalence of endometrial pathology by hysteroscopy among infertile patients in a tertiary referral hospital, from January 2015 to December 2016.  MATERIALS AND METHODS:  This is a descriptive, retrospective and observational study. The inclusion criteria were patients between 18 and 43 years of age, who had a hysteroscopy due to infertility. The exclusion criteria were patients from Reproductive Science Department who did not undergo hysteroscopy or for whom it failed. We used the software Statistical Package for the Social Sciences (SPSS) version 20.0 Data in this study were analyzed using mean ± standard deviation or expressed as percentages.  RESULTS:  Four hundred forty infertile women underwent hysteroscopy. Data from physical patient records were retrieved. Demographic characteristics included age, BMI, type of infertility, years of infertility. Hysteroscopic findings were: normal uterine cavity 38.4%, abnormal 61.6%. Some patients had 2 or more findings: polyp or endometrial polypoid 34.3%, müllerian malformation 13.4%, synechia 10.7%, leiomyoma 7.3%, endometrial hyperplasia 1.4%, adenomyosis 0.9%, foreign body 0.9%. In 7.5%, spontaneous pregnancy occurred, 21.8% underwent assisted reproduction technique, achieving pregnancy in 34.3%.  CONCLUSIONS:  Assessing of uterine cavity should be an indispensable requirement of infertile patients, since in this study more than half of them had abnormal hysteroscopic findings.]]></p></abstract>
