Objetivo Determinar los factores asociados con la presentación de gotas citoplasmáticas en porcino. Métodos Se realizó una revisión sistemática donde se encontraron 133 artículos, se eliminaron 70 por duplicados y 65 se seleccionaron finalmente: 57 en Cab Abstract, 39 en Pub Med, 20 en Agrícola y 17 en Science Direct. Se recuperaron 47 artículos en texto completo. Los datos se tabularon en EpiDataEntry, se transfirieron al programa Stata versión 12.0. Resultados Los factores más frecuentemente asociados con la presentación de gotas citoplásmicas en porcinos, son los climáticos (estacionalidad, temperatura ambiental y fotoperiodo) y la frecuencia de eyaculación de los verracos. La información a pesar de ser heterogénea y diversa, no menciona estudios realizados bajo condiciones intertropicales, ni bajo condiciones comerciales, ni involucra animales dedicados a la producción intensiva de semen para reproducción controlada. Conclusiones La información se caracteriza por su amplia heterogeneidad y diversidad de estudios. Se realiza un aporte a la Salud Pública Veterinaria colombiana sobre la importancia de las GCs como limitantes de los procesos reproductivos en porcinos. No fue posible la determinación de la relación temporal entre la causa y el efecto de las GCs.

Objective To determine the factors associated with the presence of cytoplasmic droplets in boars. Methods A systematic review was carried out in which 133 articles were found, 70 were eliminated due to duplication, and 65 were finally selected: 57 in Cab Abstract, 39 in Pub Med, 20 in Agricola, and 17 in Science Direct. Forty-seven articles were found with an available full text. Data was tabulated in EpiData Entry and transferred to the Stata version 12.0 program. Results Factors Associated with cytoplasmic droplets are: Climatic and environmental variables; ejaculation frequency with intervals of less than three weeks; spermatic morphologic alterations in tail (coiled and distal reflex); DNA fragmentation; and enzymatic factors related to seminal biochemistry. Work carried out in equatorial climate regions or that focused on the analysis of the implications of CDs in artificial insemination centers was not found. Conclusions The information is characterized by a wide heterogeneity and diversity studies. A contribution was made to Veterinary Public Health in Colombia on the importance of CGs as factors that limit reproductive processes in swine. It was not possible to determine the temporal relationship between the cause and effect of CDs.
